Magneplanar 1.7 Instruction Manual

Quick Step-Up Instructions

The 1.7 has exceptional phase characteristics that are accomplished without the use of compensation networks. To
realize the optimum phasing, the 1.7 should be angled inward to be on-axis with the listener. (Do not place parallel to the
front wall.)In most rooms, we have achieved the best imaging with the tweeters placed on the inside.The frequency
balance should be smooth for rooms with a modest amount of damping. The enclosed resistor should be used for under­damped rooms.

1. Introduction

Congratulations on your purchase. The Magneplanar 1.7 loudspeaker was conceived and designed by
perfectionists, for perfectionists. Due to the elegant simplicity and ruggedness of the design, the Magneplanar 1.7
loudspeaker will give many years of trouble-free service.

2. General Description

The 1.7 is a 3-way, full-range, quasi-ribbon design with a quasi-ribbon bass/midrange, tweeter, and super-tweeter.

3. Carton Contents

1 pair 1.7 loudspeakers
4 each feet
8 each foot bolts
8 each plastic washers
2 each 1 ohm resistors
2 each Magneplanar logos
1 each Allen wrench
1 instruction manual

4. Packaging

Save all packaging. If you need to transport the speakers, they can be shipped safely only in the original
packaging. You may never have to return your loudspeakers, but should the occasion arise, they should not be
shipped in any packaging but the original. Should you discard it, packaging is available.

5. Assembly

Before you begin -- Spacers are provided to adjust the vertical angle of the speaker. Install the spacers on the
bottom mounting bolt to tilt the speaker backwards. The amount of angle will be dependent on your particular
listening conditions. Under most conditions, stacking 2 spacers will be adequate; however, some experimentation
may be necessary.

A. Remove speakers and feet from carton. The 8 mounting bolts are installed in the speakers.
B. We suggest the assistance of a second person will facilitate the installation of the feet. Place the speaker

on its side edge.

C. Remove the 8 bolts from the internal T-nuts. Note that one end of the foot is longer than the other end.

Place the longer end toward the front of the speaker. Carefully align the foot on the backside of the panel
so the holes in the foot line up with the bolts in the panel. Using your fingers, insert a bolt through the
center hole until the bolt engages with the nut in the panel. Do not use a screwdriver until the bolt has
engaged the threads. Care must be taken not to cross-thread the bolts. Use longer bolts if spacers are

used to tilt the speaker.
D. Repeat the same procedure for top hole.
E. Tighten all the bolts securely.

6. Hookup

The 1.7 features unique, high current connectors which provide optimum contact area with the speaker cables up
to 10 gauge (or for banana connectors). Simply strip 1/2" of insulation from the end of the cable. Insert the cable
into the terminal (observing polarity), and tighten the set screws with the Allen wrench provided. Banana plug
connectors can be used and locked in place with the set screws. Spade lug adapters are available from your
Magneplanar dealer for spade connectors that are incompatible with the Magneplanar high current connector.

7. Caution

The terminal plate states a maximum fuse value of 4 amps Type 3AG ("normal" or "fast blow"). The bass section
does not require fusing protection. This fuse value should never be increased or bypassed. Do not use slow-blow
fuses. BURNED OUT TWEETERS ARE NOT COVERED UNDER THE WARRANTY.

8. Speaker Placement

Proper speaker placement and room acoustics can have a greater effect on a music system than upgrading one
of the components in the system. Unfortunately, there is no definitive guideline which will cover all possible
listening rooms. Some experimentation is required for locating the optimum position. The following are a few
general guidelines:

9. Bass Response

Play a CD with repetitive bass. Try the speakers in several possible locations in the room. Begin experimenting
with the speakers about 3 feet from the front wall. Try moving the speakers forward or backward in increments of
6 to 12 inches. One position in the room should be noticeably better than others. Also experiment with your
listening location to avoid standing waves.
