PinWooferTM – Bass Boost Unit (BBU)
The BBU is available for all PinWoofer Amplifier models (please see amplifier identification image). Please note that the KOP Amplifier has enhanced output drive so if you are looking for a simple volume adjustment solution for your external device for using the KOP Amplifier, the PinWoofer Line Trimmer is a great option:

The BBU provides volume and cutoff frequency controls at the coin door location.
Aside from the features, there are two additional considerations.
First, add more input signal to the external and it will get louder. A speaker tap routed to the popular PSW10 or equivalent may not provide a strong signal so this gadget can potentially improve that and give you more intensity / better utilize the power of the external.
Second, bass quality. The BBU roll-off is quite steep (~35dB / decade above ωc) so the result is some filtering of unwanted high bass that might otherwise originate from a speaker tap, of which the input filtering of the external sub is likely not able to fully remove. So, the BBU provides an additional screening out of unwanted higher bass frequencies so it should not be surprising that the result is a "purification" so to speak, of the bass signal provided to the external and less energy is wasted on the high bass area.
Maximum boost ~8dB (~2.5x).
Cutoff frequency is adjustable ~50-173Hz @ -3dB ωc.
Frequency roll-off ~35dB/Decade.

This control did exactly what I wanted/needed! Extended my subwoofer controls (both volume AND frequency!) To inside the coin box. After some experimenting and adjusting for the right settings, I do think it improved the quality of the subwoofer sound overall. It's the details on circuit board design and little things in life that make all off Dan's products top notch. Thanks Dan for making just what I wanted!
