The IQ900 has nine bands of equalization. Eight graphic EQ bands are centered at 125Hz, 250Hz, 500Hz,1kHz,2kHz,4kHz, 8kHz and 16kHz with a cut/boost range from +12dB to -12dB; a sub-bass equalizer section allows up to 12dB of cut or boost at a variable center frequency from 40Hz to 60Hz. The EQ slider controls are lighted red, and the rest of the unit has switchable amber or green illumination for matching with the vehicle’s interior lighting.

The unit also contains an 18dB/octave low pass electronic crossover adjustable from 60Hz to 120 Hz and an 18dB/octave high pass electronic crossover with a fixed 100 Hz crossover point. Front and rear RCA outputs are fader controlled. A separate sub-bass RCA output with front-mounted output level control is adjustable from -75dB to +6 dB.

Low level (line) and high level (speaker) inputs are provided for universal connection to a variety of different head units. For increased flexibility, input voltage range is a wide 150mV to 10Vrms.

In other KICKER news, the company asks…How big a difference in output does L7 technology make? Let’s use the new 10-inch Solo-Baric S10L7 as an example. The L7’s square cone design results in 20 percent more cone area than last year’s round Solo-Baric S10d. Xmax is 49 percent greater than last year’s model. Using these figures in the Vmax formula, the S10L7’s Vmax is 78 percent greater than the S10d. Power handling is now 600 watts, 150 watts more than the previous model.

Making the same comparison between the 10-inch Solo-Baric S10L7 and last year’s 12-inch Solo-Baric S12d, the advantages of square subwoofer technology allow the S10L7 to move 20 percent more air than last year’s 12-inch model with the same power handling capacity. A 10-inch Innovative square subwoofer technology from Stillwater Designs increases output on the new KICKER Solo-Baric L7 subwoofers enough to give users the equivalent performance of the next size larger speaker. This performance increase is on top of the Solo-Baric’s already proven ability to provide isobaric-pair performance from a single subwoofer. And, like previous versions of the Solo-Baric, enclosure requirements are among the smallest in the audio world. In 2001, new specifications for large sealed boxes or vented boxes are also available to give you the option of the kind of bass you want.

This advance in performance is primarily due to three factors, each of which results in an increase in the amount of air the subwoofer can move. By making the Solo-Baric square, cone area (or Sd) for a given size baffle is 16 to 20 percent greater than typical round cones. Increasing the Xmax - the distance the cone can move in one direction - is another way to make a speaker move more air; new ultra-length round wire voice coils and hyper-extended poles give the Solo-Baric L7 24 to 49 percent more Xmax than the previous models. The gains in Vmax (Vmax = Sd x Xmax) greatly increase the amount of air that the speaker can move. Power handling has also been increased to the capacity of the next larger driver in previous models.speaker - in a box volume of 0.66-1.0 cu.ft. - can outperform the larger 12-inch model of one of the most respected subwoofers in car audio. It’s like buying one size and getting the next size bigger in the same size box. While not as dramatic, similar comparisons may be made with all models in the line.

Power ratings range from 450 watts for the 8-inch S8L7 to 1000 watts for the 15-inch S15L7. All models have dual voice coils for the ultimate in wiring flexibility - 2-Ohm DVC models give you the option of running the sub at 1 or 4 Ohms, 4-Ohm DVC models allow 2-Ohm or 8-Ohm operation. Since the cones may be mounted much closer together than with round speakers, Solo-Baric L7 technology also allows better acoustic coupling and its resultant greater output in multi-sub installations.

The Solo-Baric’s square cone is the ultimate application of KICKER’s exclusive Inverted Structural Dome (ISD) technology which locks the dustcap into the cone for resistance against flex. The cast aluminum basket (patent pending) provides rock-solid support to control the extreme energy created when applying power to the massive moving structure. Four heavy-duty spring-loaded nickel-plate connection terminals with built-in strain relief allow positive connections, prevent speaker lead breakage, and improve the flex life of the high power speaker leads.
