PinWooferTM – DIY – “Do It Yourself”
Attention: if you are upgrading a Stern LE or have a different upgraded cabinet woofer, it is strongly recommended that you add the Cabinet Speaker Mounting Ring. You'll get poor results otherwise since the woofer will impact the cabinet floor during bass-hits and it will prematurely wear out your speaker, and you'll hear an audible "thud" during gameplay at moderate to high volumes.
This product is intended for those who want to customize their pinball audio system, have the confidence and technical know-how to do so, but want to avoid the hassle and disappointment of trying to kludge everything together separately, spending the time to do so and likely ending up with a poor result.
Do the math and factor in your time and risk of a poor outcome and you’ll see that this is a very sensible alternative to pure “DIY”!
If you are confused or unsure if this is the right pinball audio system for you, it is not. If this is the case, please select a full PinWooferTM Super Kit using the “Search” option in the upper right-hand corner of the web page. A distinct advantage of the full PinWooferTM Super Kit is that technical support is offered during the warranty period for the original target machine. The PinWooferTM Super Kit is supported by highly detailed installation videos, electronic instructions in addition to a well-developed blog that has tips and tricks to get your machine sounding great.
The PinWooferTM DIY system is minimally supported outside of the warranty terms, and while instructions for connection are provided, technical support is not readily included. The DIY is brutally simple and if you have a problem, please take the time required to diagnose what might be wrong with your setup before contacting us.

PinWooferTM – Optional 8in Cabinet Mounting Ring
Vital for good cabinet sound - this ring has a 0.375" dwell that allows for cone and surround excursion when the bass is pumping.
The PinWoofer cabinet mounting ring fits a standard 8" speaker mounting hole pattern of 7.625" +/- 0.125" diameter. It also matches the cabinet floor bolt pattern found in Stern SAM, Spike and Spike-2 machines.
Most 8" woofers have a standard hole pattern that fits this ring, but you must verify your woofer dimensions prior to ordering to ensure your speaker fits.
This is a rigid PVC injection molded ring that is offered nowhere else. The rigid material provides a tight coupling to the cabinet which improves efficency and tonal response.
Ring secures to cabinet floor, and the speaker mounts to the ring. Included are eight each #6 flat washers and #6-32 nylon locking nuts.
2.1 MAX Amplification - 50Wx50Wx100W Final Stage*
Optionally select other items as listed to support your install.
* Average maximum amplifier power in application can be approximated by taking the product of the MAX power rating per channel and 1/(√2*1.5) and average maximum RMS Power is determined by a further 1.5 divisor.

I came across the DIY solution after having great experience with GT Pinwoofer on my JJP. I replaced my factory 4 1/4 in speakers with Kenwood KFC-1366S 5 1/4 in to accompany the Speakerlights.com Deluxe kit mainly for LE looks on my premium Deadpool. The sound at proper 4 Ohms was garbage, not just volume but overall... Looking for another solution with a clean power source, external amp, sub out, and equalizer controls to really take advantage of the Kenwoods, I came back to Pinwoofer. This solution fits the bill in everything I needed. The Kenwoods may not perform as well as the Pyle's which come with the full Pinwoofer GT and KO kits, but they sound great and much improved to the Spike Amp to my ears, so if your looking for an LE look with the White speakers and a perfect sound package, this is it. I am also using an External Klipsch 12 inch sub with the DIY amp and it sounds great add well, nice tight bass thump without scattered muddy sound that I was getting from the sub out on the internal amp I was using earlier. A+ across the board!!! Dan is always very responsive and a great customer supporter as well. Can't say enough good things about Pinwoofer and Dan!
