FEATURES
SPL 65 Midrange / Woofer
The SPL 65 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 65'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 65 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 
operating in parallel providing an easier load for an amplifier
