FEATURES

SPL 55 Midrange / Woofer

The SPL 55 is an excellent performer with a combination of high
sensitivity, solid bass and smooth response throughout the audible
range.

• Lightweight Cone designed for good rigidity and high sensitivity

• 2 Ohm Voice Coil for increased voltage sensitivity and higher

output

Aluminum Dome Neodymium Tweeter

The SPL 55's coaxially mounted tweeter is a high performance 1”
Neodymium tweeter designed to deliver outstanding high frequency
reproduction.

• Black Aluminum 1" dome for improved power handling and

linear response

• Ferrofluid-immersed Voice Coil enhances heat dissipation

• Vented Aluminum Voice Coil Former for superb heat dissipation

and high power handling

Passive Crossover Network

• The crossover consists of high quality, 2 pole design for improved
power handling, lower distortion and better imaging.

• Acoustic Summation design combines the crossover with the
speaker's natural roll-off for a steeper slope and increased power

• Dynamic tweeter protection allows for improved power handling
and continuous output

2 Ohm Nominal System Impedance

The 2 Ohm impedance design of the SPL 55 system provides an overall
3 dB increase in output compared to a 4 Ohm design.

•Effectively a doubling of Sound Pressure Level -- with the same
voltage input

•More stable, phase coherent load than two 4 Ohm speakers
