Standard subwoofer pictured, upgrade can be seen here
The SWTR-4ST kit is designed for the new style metal back box, and Vault Editions and 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-4 ST 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. Special Hardware included for mounting into the new metal back box
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. Don’t risk damage to your sound card with kits using 4-Ohm speakers.
The SWTR-4ST kit is for the latest Stern pinball machines with the Stern S.A.M. System CPU/sound card (520-5246-00) and comes with a SW-4V sub-woofer, two 4 inch backbox speakers and a volume control with attached wiring harness as shown below.
For any major pinball flipper looking for high fidelity sound! Consider an upgrade for the ultimate treatment for your high end restore. The sound is one of the few things that are a must for your pinball machine!
