FEATURES
SPL 4 Midrange / Woofer
The SPL 4 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 output
SPL 1 Aluminum Dome Neodymium Tweeter
The SPL 1 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
SPL 4X Passive Crossover Network
The SPL 4X crossover consists of high quality, multi-element
components with a two position tweeter level control. This allows
tailoring high frequency output to the installation and individual
preferences.
• 24 dB/octave Acoustic Summation Crossover Slopes
• Variable tweeter control for added flexibility
• Dynamic tweeter protection allows for improved power handling
and continuous output
• Ultra-low DCR Inductors for minimal signal loss (High power
Ferrite in woofer path)
2 Ohm Nominal System Impedance
The 2 Ohm impedance design of the SPL 40 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
amplifier voltage output
•More stable, phase coherent load than two 4 Ohm speakers
