Revolutionary Pinball Amplifier and Speaker Upgrades
Why PinWoofer?

At PinWooferTM our goal is to enable the best sound possible and unlock the full potential of the audio track. Our approach is to provide:

  • The top speakers in the industry that produce a clear backbox sound field and deep, rich bass.

  • A well matched and feature rich amplifier specifically designed for a pinball machine.

Replacing the speakers alone does little to improve the overall presence of your title because you are still stuck with the de-rated stock amplifier. The typical pinball machine amplifier is no better than what is found in a television or clock radio.


The PinWoofer amp provides clean track reproduction that has been perfectly balanced for a pinball machine with deep bass, defined mid-range and a crisp backbox recreating detailed call-outs, music and effects. You'll hear the bass and feel it in your hands.


Increased amplification is vital to improving dynamic range, which is the difference between the quietest and loudest sounds in the audio track. With the PinWoofer amp, at any volume level you'll hear a dramatic improvement as the cabinet and backbox are liberated from the stock amplifier.


PinWoofer offers three amplifier formats:
1) The PinWoofer "GTP" or "Glass Tamer Plus" which is available for all platforms we service, and has a rich feature set including a pro level line out, a differential input with gain control, auto-muting for older titles that may have developed noise over time, and a proprietary glass shake reduction technology - a nice feature for some titles that have a bass intensive track.
2) The PinWoofer "KOP" or "Knockout Plus" is a slightly simplified pinball amplifier compared to our "GTP" amp (includes a pro level line out), initially targeted for Jersey Jack Pinball and Stern Spike Titles. The KOP Amp removes the Auto Muting and Pre-Amplifier with Gain Control features that are generally not needed on these modern platforms. The KOP also removed is the Glass Tamer (TM) feature as part of cost reduction.
3) The Do It Yourself, or "DIY" amplifier which has the same amplifier electronics as the KOP, but takes it out of the enclosure and mounts to the backplane. It is a cost reduction and as such, there is no wiring harness to the coin door location which reduces the convience of adjustment.


All PinWoofer amplifiers feature cutoff and tone controls.


Our system is simple to install and anyone can do it!


Our products are assembled in the USA so you can feel good about having a product that supports American manufacturing.
