Page 2 Thank you for your support of Kicker products, and especially our subwoofers. The KICKER subwoofer has always been at the forefront of speaker technology and the latest versions are no different. Our technical and R&D staffs have designed some extreme enclosures beyond the sealed boxes to give the end user some choices when it comes to earth shaking bass in their car.
Page 3 2 - Extended low frequency response and smooth roll off (12 dB/octave). 3 - Excellent transient response. 4 - Tolerant of minor enclosure size variations. 5 - Easiest enclosure to build. Cons 1 - Not as efficient as other designs. Kicker Technical Tips Vol. 1 Page 2...
Page 4 5 - Vented enclosures usually don’t sound as fast as sealed boxes because the resonant effects of the vent tuning, is always slightly out of phase with the driver’s output. Kicker Technical Tips Vol. 1 Page 3...
Page 5 4. Generally requires 50 to 100% more total enclosure volume than vented or sealed types. 5. Usually has less power handling than a simple sealed box. Designing bandpass enclosures for increased power handling can result in very poor deep bass response. Kicker Technical Tips Vol. 1 Page 4...
Page 6 On a sedan or any other car with a conventional trunk, it is very important to couple the enclosure to the interior through a package tray or rear seat area. Failure to do so will allow can- cellation of much of the low bass information. Kicker Technical Tips Vol. 1 Page 5...
Page 7 36” (1m), but there is already a corner brace on the adjacent wall, we’d need to deduct one inch (2.5cm) so that the braces fit together- not overlap. Deduct two inches (5cm) from a brace’s length if there are braces on both adjacent walls. Kicker Technical Tips Vol. 1 Page 6...
Page 8 Place the brace slightly off center for maximum rigidity. A perfectly centered cross brace can actually increase cabinet flex and resonance (at a higher, more audible frequency Kicker Technical Tips Vol. 1 Page 7...
Page 9 Height x Length x Width = Total Cubic Inches 12" Total Cubic Inches/ 1728 = Total Cubic Feet Total Cubic Feet/ # of Drivers = Total Cubic Feet Per Driver 1728 Cubic Inches = One Cubic Foot Kicker Technical Tips Vol. 1 Page 8...
Page 10 Guess what? It is coming back to haunt you! It really is pretty simple. If only the teacher could have related it to car audio, we might have paid more attention. Are you ready? Area x Length = Volume. Isn’t that simple? Kicker Technical Tips Vol. 1 Page 9...
Page 11 Driver Displacement: The driver also takes up air space inside the enclosure. If you use Kicker speakers, we’ve made calculating driver displacement real simple for you, just flip to the chart on page 14 of this sec- tion.
Page 12 Result - we use 12” Kicker Comp VR woofers in a sealed enclosure! Another possibility though, is the 10” Kicker Comp VR in a ported enclosure. It can be quite a long process to figure all these different things, but...
Page 13 5 + 13 = 18 18/2 = 9 17" Instead of using the entire height dimension, deduct the height of the riser, 4” for this example. 9" 17” - 4” = 14” High 4" 13" Kicker Technical Tips Vol. 1 Page 12...
Page 14 17" 0.46 + 1.13 = 1.59 cu. ft. total per driver This is your net internal airspace for each side of this 9" enclosure. That was not very tough, was it? 4" 13" Kicker Technical Tips Vol. 1 Page 13...

Page 16 The smallest change in loudness that a human can detect is defined as one decibel. Directionality- Determined by the angle into which a speaker radiates its sound. A speaker with a narrow angle of dispersion is very directional, while a wide angle of dispersion is more nondirectional. Kicker Technical Tips Vol. 1 Page 15...
Page 17 Lowpass- When information higher in frequency than a given crossover point is attenuated, a lowpass fil- ter is in use. A common application is for woofers. Kicker Technical Tips Vol. 1 Page 16...
Page 18 Qts- The driver’s magnification at resonance. A measure of the driver’s ability to dampen its resonance. Resonant Frequency- (Fs). Frequency at which a driver most easily responds to an external force and continues to vibrate after the force is removed. Measured in Hz. Kicker Technical Tips Vol. 1 Page 17...
Page 19 Woofer- A driver designed to reproduce low frequencies. In car audio it is usually restricted to 100Hz and below. A woofer that is used down below 40Hz can be called a subwoofer. Z- See impedance. Kicker Technical Tips Vol. 1 Page 18...

Page 21 All of these designs need some internal bracing. Be sure to add 2”x2” to 3”x3” triangle braces between each of the larger unsupported panels. Kicker recom- mends using a good grade of wood glue and silicone sealer for an airtight box.

Page 29 Greg: Tuning vehicles for competition is a passion for me. First-time competitor or World Class pro, seeing a competitor on stage is one of the most rewarding aspects of my position at Kicker. Tuning is a vast, and sometimes controversial subject that I cannot fully cover in the scope of one interview. My goal is to get the competitor to approach tuning with a systematic approach.
