Greetings Shredso ! First, thank you for doing such a detailed and objective review - we really appreciate the attention to detail and the time required to this.

We listened carefully to the audio clips. In our opinion, you are spot-on with your "low mids" comment; the moment the PinWoofer track started it was immediately apparent to us what was in play. There is most definitely a signature in the 200-500Hz range from our kit. An external sub typically has it's power concentrated below 200Hz and a stock cabinet speaker is pretty weak below about 500Hz. The in-cabinet PinWoofer driver has a great response below 200Hz but a superior response in the 200-500Hz range which improves the blend in the low-mid / high bass band. This is where much of the track "presence" can be found.

One final comment and possibly the most important. The backbox amp and speakers are vital to balancing the system. With the exception of a few titles / trims, the vast majority of stock backboxes fall woefully short of the potential that the track offers. With improved backbox speakers and our amp, one can hear call-outs and effects with much greater clarity and well defined bracketing compared to the de-rated stock amp and paper cone speakers.

We offer a complete solution.

I can't tell you how much we appreciate your patience on the install time and with the instructions. Back in the day I would say "installs in about an hour" but I revised that to "one to two hours" because realistically, that's what it takes. However, once you see what's going on the second kit is much easier. A similar comparison might be installing a car stereo; that will take a couple of hours so I don't know that our install time is completely unreasonable but we are working hard to bring it down in a significant way.

Quality instructions are difficult to write and I've received many an email literally saying "great instructions, it was easy" etc., while other guys have constructive feedback which we take seriously and incorporate as much as is possible and relevant. Some feedback is in-between but in the end I am certain we have never left anyone behind since we track every kit outcome closely. We have some open cases for guys who don't respond / stop responding, and we stop hounding them after two emails and 60 days. I am always willing to help break you loose so I hope that making myself available to help out makes up for any troubles you might have.

Learning the subtle differences among the 125+ titles we support and the different trim packages, vault runs and speaker panels, other speaker kit wiring and not to mention documentation errors in the manufacturers manuals and specs has been a huge challenge. It is impossible for us to know all of these variants at time zero but over time, customer interaction and feedback have helped us to become what we are today and we are immensely appreciative of this. It really bothers me when a customer is "broken" or must deal with a specific variance and feed it back to us. The good news is that we have matured and there are far fewer surprises today compared to 6-12 months ago so the effort has been worth the outcome!

Thank you for your strong support!

Awesome guys - thanks for the accolades - have fun!!!

Greetings @ballykiss1978! Great chatting with you today, thanks for reaching out!

Below is the comparison we talked about.

A teardown of that amp is shown below. This unit is branded several different ways depending on the distributor. Single sided PCB, through hole components, some jumper wires. (This is not to say it's a bad option because it does meet needs, just some observations on its construction.)

Next, a few PinWoofer amps, undressed. Appearance won't always tell the story, but I think the difference in effort here is clear. We use the best materials possible; SMT, large decoupling caps, custom heat sink, extensive ground plane / polygons, thermal vias, and a high-end enclosure for our Plus Series Amps. We have invested heavily into our electronics and offer what we think is most well-designed pinball audio upgrade possible. If we have a design issue, we fix it. (For transparency, we did use a commercial amp years ago, but have since migrated to 100% in-house PCB design.)

OK, just a fun look inside. Have a great day, and thanks for your attention!
