Standard Subwoofer pictured
ESPECIALLY DESIGNED FOR SPIKE SYSTEMS. With new wiring and Stereo volume control. Don’t buy systems that skip the wiring and added control just to save a few bucks. The SWTR-4B kit provides an 8-inch sub-woofer with attached network to replace the original 8 inch speaker. The special design of the sub-woofer network routes the low frequencies to the sub-woofer which extends bass reproduction to 32 Hz. for unbelievable sound. The SWTR-4B kit includes new 4-inch 8-Ohm backbox speakers and a stereo volume control for the back box speaker levels that provides for greater bass output from the sub-woofer. No permanent modification is required to the pinball machine.
Our 8-Ohm backbox speaker will not overload the games audio amplifier like other kits can. The 8-Ohm speakers wired in stereo match up with our 4-Ohm L-Pad control for the perfect solution. The amplifier sees a constant load over the volume range and the L-Pad drops completely out at full volume. Kits using 4-Ohm automotive speakers can cause overload to the amplifier if run in parallel (2-Ohms) or lose 2db of high frequency sound if run in series. Don’t risk damage to your sound card with kits using 4-Ohm speakers.
The SWTR-4B kit is for the latest Stern pinball machines with the Stern SPIKE System CPU/sound card and comes with a SW-4V sub-woofer, two 4 inch backbox speakers and a volume control with attached wiring harness as shown below.
