Features

— Mica Filled Polypropylene with a Titanium Deposit Coated Cone An Ultra High Performance look that
makes the Solo-Baric® L7 truly a statement piece. The cone gives you deeper and stronger bass at higher listening
levels with less distortion due to less tendency to flex. Because, when a woofer cone flexes, there is a loss of out­put. This loss of output translates into less bass.

—

—

Re-engineered rear cone brace In order to keep up with the demands on the cone at extreme listening

levels, the rear brace has been re-designed and strengthened to reduce the cone flex. The brace works in conjunc­tion with the other components of the cone, to insure that cone flex does not decrease the output of the woofer.

— Massive Surround Radius High SPL=VMAX=Cone area + Xmax + surround radius. What does this mean?
According to Dr. Koneairea, the Vmax of the driver takes into account the cone area as well as the Xmax of the
driver. To increase the Xmax - the distance the cone can move in one direction - the surround must be large
enough to handle the demands. Taking this into consideration, the new Solo-Baric L7 surround has been increased
to handle the massive power needed for high SPL.

— One Piece Front and Rear Gaskets Instead of using the cork gaskets, which can separate, the new L7’s have
a one-piece gasket on both the front and rear of the mounting flange. It is more durable and ergonomically pleas­ing to the eye. The previous cork gaskets could tear off if you were transplanting the speaker into another box, or
they could stay adhered to the old box causing you to order another gasket. These problems are eliminated with
the new rubber gaskets. They not only look better, but also function better by eliminating the chance for air
leaks.(provided the box is built correctly!) We still recommend if you are carpeting the box, to cut away any carpet
that is under the woofer mounting flange to insure a tight seal.

— SSD (Spun Spoke Design) The basket not only looks impressive, but it is extremely functional. This cast alu­minum basket provides a solid foundation for the motor assembly insuring that all the parts work together in har­mony and prevent shifting or misalignment. Without a solid foundation, the speaker’s various parts could shift
under extreme excursion causing premature failure and add unwanted noise to the music. If misaligned, the voice
coilcould rub the inner wall of the motor structure and thus exposing the bare windings, which would cause speak­er failure. The same thing happens if the coil former rubs the pole-piece. The damaged former exposes the wind­ings causing speaker failure. When other speakers are pushed to their limits they tend to make noises that add col­oration to the music. When you’’re LIVIN’LOUD you only want to hear the music the artist intended you to hear, not
a bunch of unwanted ringing.

— Perimeter Venting Without the perimeter venting along the side of the speaker, hot air would be trapped in
with the voice coil. This will cause the structure to heat up quicker and cause power compression, which results in
decreased output, as well as shorter speaker life. Perimeter venting causes a vortex cooling effect around the coil
which exchanges the hot air around the voice coil for cooler air outside the speaker. It also releases pressure from
under the spider to allow the speaker to work in a more linear fashion. All of this translates into cooler operating
temperatures which will allow the speaker to sound and perform better.

FEATURES cont.

ä

— Blackened One Piece Uniplate

11.

.

Provides enhanced heat transfer for cool operation and maximum power handling. The heat is transferred

from the pole piece to the back plate, effectively acting like a radiator in an engine. This lowers the operating
temperature of the voice coil. Note:The increase in temperature increases the impedance of the
speaker. This results in lower output and is referred to as Power Compression.

22.

.

Reduces non-linear magnetic fields around the voice coil gap for superior cone motion control. The
extended pole assures the voice coil is always in the magnetic field when moving peak to peak. When the speaker
reaches it’s Xmax, the voice coil is still in the gap between the pole piece and magnet structure due to its extended
pole-piece.

33.

.

Releases pressure under ISD for freer cone motion and enhanced low frequency response. Air trapped
under the ISD is forced out though the pole-piece to allow the cone to move freely. Heat and pressure build up
under the ISD and need to be released to allow the speaker to function properly.

— High-Temp Kapton® Voice Coil Former Heat is the primary enemy to the life of a speaker, which is one of
the reasons we use Kapton® voice coil formers. Kapton® is a man-made product that is light, durable and
heat-resistant. The Kapton® former acts as an insulator to keep the heat of the voice coil from breaking down the
adhesive that connects the voice coil to the cone. During high excursion and prolonged exposure to heat, the
Kapton® former holds its shape and does not expand or contract. As a bonus, Kapton® is also a very quiet material
and during operation, does not discolor the music by adding unwanted sound.

— ISD (Inverted Structural Dome

)

Kicker was one of the first companies to switch to the Inverted Structural
Dome. We have designed a cone with a groove for the ISD to lock into, further adding strength to structure. When
a cone reaches it’s peak it wants to buckle because it’s momentum keeps it moving out. The ISD provides
structural support for the cone to resist buckling. NOTE: When the cone buckles, the output of the woofer
decreases. Therefore, the ISD is not just a cosmetic thing, it is an integral part of the woofer to maintain it’s
maximum performance.

— Stitched Surround A signature of KICKER woofers has always been the stitched surround. It prevents the
surround from separating from the cone at high excursions. When the woofer is moving back and forth it puts a
lot of strain on the adhesive that is holding the surround to the cone and often causes the two to separate.
Stitching the surround to the cone eliminates this from happening.

If stitching were inexpensive, everybody would

do it!

—

—

Dual Ultra-Length Voice Coils A speaker can obtain extreme Xmax only when the voice coil is long enough

and can sustain the stress. Dual voice coils give the installer the option of several different wiring configurations
compatible with any amplifier.

In addition, the S15L7 has Dual spiders to help control the massive structure!

— Sleeved High-Power Tinsel Lead Wires Resist lead breakage and power robbing resistance losses under
demanding conditions. When a speaker is being pushed to it’s limits there is a lot of strain being put on the leads,
especially on high performance woofers like the Solo-Baric® L7. Sleeving tinsel leads help strengthen them to resist
breakage.

—

—

Spring-Loaded Nickel Plated Terminals On a High Performance speaker like the Solo-Baric® L7, you would

expect nothing less than a High Performance terminal. They allow the installer to use the maximum gauge wire to
minimize power losses for the ultimate Ground Poundin’ system.

Thank you for your support of Kicker products, and especially our Solo-Baric® L7 (patent pending) square

subwoofers. The SL7s are truly unique products in a world of round subwoofers. Our technical and R&D staffs have
designed some extreme enclosures beyond the small sealed boxes Solo-Barics are famous for. They have
unleashed the awesome capabilities of the L7s.

In this paper we will explore some applications for the Solo-Baric® L7 complete with box drawings and cut sheets

plus some important information regarding the break-in period for this ground-breaking speaker.

Important Break-In Information

Due to the complex nature of the Solo-Baric® L7s they require a little extra time to break-in. Especially in sealed

enclosures, break-in is a must in order for woofers to produce optimum low bass response. Due to the high
performance suspension system incorporated in the Solo-Barics they are very stiff “out of the box”. Approximately
two weeks of daily playing will allow the suspension to break-in and reach its optimum equilibrium. The “broken-in“
sub will exhibit stronger bass performance, smoother response, and greater low bass extension.

For those of you with more sophisticated audio equipment, the Solo-Barics can be broken-in on the test bench

overnight with the following procedure.

Solo-Baric Freeair Break-in Procedure

1. Connect the speaker to a power amp of about fifty watts or more. The speaker should not be mounted in any
enclosure - just freeair.

Please make sure it will not walk off the bench while it is playing!

2. Connect an audio generator to the input of the power amp, and adjust the generator to approximately 45Hz for
the S8L7, 35 Hz for the S10L7, 30 Hz for the S12L7, and 20 Hz for the S15L7.

3. Now adjust the gain on the amplifier and generator so that the cone is moving to Xmax. This can be determined
visually by looking at the “blur depth” of the logo on the ISD. A close approximation will do. On the S8L7 this will be
about 3/4”, on the S10L7 about 1”, on the S12L7 about 1”, and on the S15L7 about 1 1/4”.

NOTE: Keep in mind that as the speaker is used under normal conditions the break-in will continue, so if you don’t
have time for the complete break-in period the speaker will still break-in itself under normal usage.

Sealed Enclosure Applications

The Kicker Solo-Baric® SL7 woofers are designed to give more output than an equivalent round speaker. The SL7

is amazing when used in the recommended sealed boxes. These sealed enclosure SQ recommendations will give
the smoothest response with the most energy at really low frequencies, around 20 to 30 Hz.

The recommended

CCoommppaacctt

sealed boxes are in line with our traditional Solo-Baric enclosures. They have the
highest power handling capability of all our recommended enclosure designs. They deliver massive amounts of
high impact bass and can be driven with punishing levels of amplifier power.

One of the benefits of the L7-Series high performance suspension system is that the Solo-Barics can operate in
larger sealed enclosures for ultra sound quality (SQ) applications without significantly sacrificing their power
handling. This extra bass extension and smoothness can be obtained by simply using a larger sealed enclosure. The
box can be “sized up” all the way to a .707 Qtc. enclosure, which has a very flat response, with greatly extended
sub bass.

Solo-Baric® L7 series woofers also perform well in any sealed enclosure between the

CCoommppaacct

t

and

sizes. These

SSQQ
systems will exhibit some benefits of both (high impact and low extension) generally sounding more like the box to
which they are most closely sized.

Characteristics of Sealed Enclosures

The most basic and simple of all speaker enclosures is the sealed box or acoustic suspension design.

The acoustic suspension design has several advantages; it is easy to build, easy to tune and offers high power
handling, tight response and extended low end output. Acoustic suspension enclosures roll off at 12 dB
per/octave. Cone motion is better controlled at all frequencies because of the constant pressure on the back side
of the cone, which enables you to run more power to the woofer. They are called acoustic suspension enclosures
because the air inside the box acts like a viscous brake to control the woofer. That is why the box
tight. If there are any air leaks in the enclosure, the woofer cannot function properly.

Note: Grill shown on diagram is
optional please see your Kicker
dealer for purchase.

Ported/Vented Enclosure Applications

Ported Solo-Barics incorporate massive slot loaded ports with ultra low air velocity for ground pounding street
bass that will make your hair stand on end (if you have any left)! These are the enclosures of choice for outrageous
street bass and high performance SPL contests.

The following chart shows three recommended ported enclosures for each Solo-Baric driver.

Compact has increased bass efficiency over a sealed enclosure, yet can still fit in tighter applications.
It is the smallest design that will work well for each woofer. Although it is the smallest ported enclosure the output
from 30 to 80 HZ will be considerably higher than that of a sealed box. This smallest vented design is for places
where you can only give up the room normally taken up by two L7s in the normal small sealed boxes. The two
other ported designs have proportionately more output in this region.

Street Bass is a medium sized enclosure that will kick out bass that can be heard for blocks away. And it does
go LOW!

Finally, SPL / Deep Bass is a large enclosure that has it all. It is high efficiency and will deliver the output needed
to win SPL contests, yet low frequencies go all the way down to the basement - with power that will shake the
foundations! We’re talking truly awesome.

If space is not at a premium and you want to get the most from your Solo-Baric® L7, try one of these designs.
You won’t be disappointed. Note: You must add the port volume to the volume of the box! See the

cut sheets.

Characteristics of Vented Enclosures

A vented enclosure is not much more complex than a sealed box. It consists, basically, of a box with a hole in
it. However, despite its simple design, vented boxes are considerably harder to get good performance from
than sealed boxes - although many times the extra effort can be worth it.

The vent in the enclosure interacts with the volume of air in the cabinet and the driver to help increase
output and reduce cone excursion at and around the tuning frequency. In fact, at box tuning, almost all the
bass is produced by the vent - NOT the woofer.

The trick in building a vented box is to get the right size enclosure and the right size vent. You can’t be to far
off on either of these factors or your speaker’s performance will suffer. In particular, using a too-small box or a
too-high vent tuning frequency can eliminate bass instead of increasing it. Porting a sealed box that is too
small usually does nothing to improve frequency response. The vents placement within the enclosure is also
important. You must leave at least the equivalent of the vents diameter between the vent and any inside wall.
For example, you would not place a vent with a 3” diameter within 3” of any wall. The same is true for clearance
between the vent opening and the bottom of the enclosure.

PPrroos

s

1 - Reduced cone excursion and reduced distortion around vent tuning.
2 - Increased output capabilities around vent tuning.
3 - Vented boxes give you that extra “Bump” that is preferred in certain types of music.

CCoonns

s

1 - Total loss of cone control below vent tuning, which can result in high distortion and driver mechanical
failure.
2 - Midrange sound coming from inside the box through the vent can produce unpleasant sound coloration.
3 - Vented enclosures are more sensitive to changes such as temperature, humidity and driver fatigue.
4 - Enclosure design is more complex and the enclosure itself must be more solidly constructed because
internal pressure at frequencies around vent tuning can be nearly twice as high as a sealed enclosure.
5 - Vented enclosures usually don’t sound as fast as sealed boxes because the resonant effects of the vent
tuning which is always slightly out of phase with the driver’s output.

Box Building & Mounting Hints

All the cubic feet numbers given in the supplied charts include the displacement of the woofer. For the
ported boxes the displacement of the port must be added to the final design. It will be impractical to use
round ports for these designs. The rectangular port information given will yield the best results.

Always use 3/4” or thicker MDF and make sure all the joints are
secure and well sealed. The peak pressure in a ported box can
exceed that of a sealed enclosure. All of these designs need some
internal bracing. Be sure to add 2”x2” to 3”x3” triangle braces
between each of the larger unsupported panels. Kicker
recommends using a good grade of wood glue and silicone sealer
for an airtight box.

Note:If you prefer an ultra-smooth bass response, you should
loosely fill your ported Solo-Baric Enclosure with polyfil. If you do
so, the entrance to the port (inside the box) must be covered with
hardware cloth, chicken wire, or expanded metal to prevent the
polyfil from being blown out through the port. Use of polyfil will
slightly decrease efficiency, but will deepen and extend low bass
response.

Do not install a ported box with the port against a
solid surface. The port opening must remain
unobstructed. Use the smallest dimension of the
rectangular port as the minimum amount of space
required between the port and any surface to insure
unrestricted airflow.

If you would like to use a vented enclosure, but the box designs we provide you with (in this manual) do not fit
because of width or depth, the designs can be modified. The shape of the enclosure is not vital, but
The volume, of the design you choose, must stay the same. The following diagrams provide you with some help to
insure your enclosure is built correctly.

damage your hearing! Turning up a system to a level that has audible distortion is more
damaging to your ears than listening to an undistorted system at the same volume level. The
