SWTR- 4A kit
for Stern & Late SEGA Pinball Machines (Whitestar)
The SWTR-4A 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-4A 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 parallel 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. Go to www.pinballspeakers.com for an informative and interesting presentation on backbox speaker testing. Don’t risk damage to your sound card with kits using 4-Ohm speakers.
