Does anyone just happen to have a BassCube schematic???

Larry Frederick here, trying to fix one ...

PROTOTYPE PRODUCT THAT NEVER SAW PRODUCTION (One of many products over the years, there was a computerized 1/3 octave EQ that I developed too, we showed at the 1994-95 CES..don't know where that one is??) I think we made this for the 1993 or 94 CES show. Again one of my projects that never got into...

Actually I built a set for a CES (I think 1997) white pearl enclosure similar to Wilson Watts Tots. 2 Layers of Ranger Board (non of that wussy MDF) 2.5 inches think on all walls, BRACED internally. Dom built custom crossovers (because of the on-axis design of home speakers, different that the car o...

We built it for CES 1990. It was as everyone figured out, our statement piece. It was to be a real production amplifier after the show. But at that time our resources were limited (not like 1996 when it was UNLIMITED!!). 7 employees hidden in a closed off area on the 2nd floor of Tom Peterson's Furn...

Wow, how old are these photos of the MP6300? And who has it now?? Man!!! haven't see that amp in over 16 yrs now. Hand built (by me) at CES 1990 36 hours straight to finish the build. It is all real, other than: 1. The boards were to be 4 layer, but we only had time for 2 layer (so it WONT power up ...

No ....you and Bill and Brian are MR Ellis Island!!! (didn't you guys get banned from there like FOREVER ??? )

It will be interesting to see, for sure.

Free advise from Larry...NOT Audison...get it straight!!!!

Shorten the vent about 3 inches and it will tune about 32HZ and be MUCH flatter in response. Just go get WinISD Pro. Its FREE and what I teach to all HERTZ retialers to use. Super easy , and FREE!!!!!!

Going BIG (meaning long BIG amplifiers) is TOTALLY the wrong direction. In my opinion. Yes, for a small die-hard group it may be fine. But the reality is WE ALL want big power ...small package!! And if you do a marketing study of what RF, JL, ARC and a bunch of others are doing... ONLY their small f...

There was under 200 of FAS. We just ran out of MQ430 boards. That is the real reason we didn't make anymore :) PRODUCT to build??? Make a series of amps that are small (Philips chip set is really cool by the way). But make the power ratios correct (where as ARC didn't!!) Like a 4 X 100 , 1 X 500 4 o...

LRx is built EXTREMELY well. Think PG 21st century. Seriously!!

In the Thesis amps we use solid state capacitors!!! They are the SHIT for sure!!!

They'd have to pay me a LOT of money...and build the right stuff to make it all happen. But...saying that, having Morgan there ain't bad :) My best recommendation is to do a MS275/2125 circa 21st century! Build a few "State of the Art" models,and then the normal meal ticket stuff. Right no...

Yeah, we had an outside house do our "daughter " boards in SMD. Cause we didn't have the SMD setup internally. We were thinking about it. But with ClassA/B amplifers we still needed mass and surface area, so it didnt do much good to make the boards more compact as you had all these output ...

Did PG EVER do SMD??? Really? Not that I know of (as of 2000 for in house build stuff), at least not any REAL amplifiers (MS/MPS/ZPA/ZX/ZXi ???

Compete with ZX450?? Probably I would say an LRx 4.1K 2 X 130 and 2 X 140 http://www.audison.eu/index_main.php?Section=LRX41k Not small like the ZX, but real powerful. Don;t have any issues with bad pots either :) Power wise probably the LRx4.5 http://www.audison.eu/index_main.php?Section=LRX45 VRx ...

Actually Ben Heil and myself built ALL the parts to that beast. MPH-6300 Was a killer "Art project" for sure :) I machined all the standoffs, metal cages, 25 pounds of 1/4 thick copper bussbars, etc. Then spent 3 days with NO sleep at CES putting it together. 36 -TO3's for switchers AND ou...

Remember I am the "idea" guy. I only know enough to be REALLY dangerous. Not a EE. I have patents on the "design", cosmetically and mechically for the ZX and ZPA. And 5 Design and Engineering Awards. Put an engineer? Only if I wear one of those funny striped hats Train enginners ...

Stupid go look at our THESIS, 6 -shielded Power supplies, 4 just for the output rails, dual monorual and one for each positive and negative, plus 2 more shielded supplies for the front end. And this is a stereo 400 watt per channel amplifier! Solid State capacitors! 4 layer 4 mil thick copper clad P...

I got a MILLION of 'em

Yes - Parts used, board layout, materials, etc. We (well PG) at the time (early 90's) built THE best car audio amplifiers in the WORLD! PERIOD!!! Best parts, best PCB, best design, etc. All the things that mean...the best. You cannot say your the best, and use TIP35/36 output devices in an amplifier...

And what is even werider is we put a GIANT ASS BRIGHT YELLOW sticker on the top Plex ..telling whomever that there was a switch!

What can I say...People amaze me on a daily basis

ZPA's are still the BEST under $2,000 car audio amplifer ever built. Not quite up the HC-100 or THESIS HV Venti




But this amplifer is now ONLY $12,500.00 retial. So not in the same ball park

ZPA's HAVE to have a Line Driver (TBA??) of some type as their input gain structure was very low. Like 2-8 volts, instead of the more normal .2 -4 volts that 99% of all other amplifiers built have. Remember that this was the "KRELL/Mark Levinsion" of car amplifers. And becasue of the cool ...

If they would have let me keep designing product, I would have stayed. But..becasue I was such a "great " ambassador for the company out in the field ( the whole damn world!!) they just wanted me to keep flying around. Shaking hands and kissing babies stuff. I have a wife and 2 kids! I don...

We found that at about 400 watts RMS, the "blades" would "shear" off. Actually the tip of the blades would hit the bottom edge of the "ski slope" (If you've seen a cyclone you know what I mean) It took us a long time to figure out that we didn't need that much power. Wh...
