 SP-8 Subwoofer/Speaker for Bally-WIllams Pinball Games

The SP-8 is a subwoofer-speaker specifically made for early Bally – Williams pinball games.  It comes with a gasket spacer for direct mounting on the floor of the game or you can use the adapter plate that mounts to a 6 ½ inch stud pattern found in some games. This gives you flexibility in fitting it to your game. The impedance is 8 ohms matched to the pinball game amplifier so it won’t over load it.  You will get the full range of sounds plus the low frequencies missing in the stock speaker.  This is a high quality subwoofer speaker that will out last your game.  The dual cone design supports 20 – 18,000 Hz operation – well beyond the capabilities that the pinball machine can produce. For machines manufactured from 1977 through 1984 having a sound board with one speaker driver output.

    Compared to the stock speaker………there is no comparison! Install was easy and the sound improvement is great. I installed this in my Firepower and am thrilled with it. The sound is clearer and warmer than with the stock speaker. Volume can be turned up louder now without the speaker failing. And it looks super cool sitting in the bottom of the cabinet!
