Does Anybody Remember Rocket Speakers?

He signed a contract with me (we knew a lot of the same people such as Howard Schilling and Bob Rapport) and he just stiffed me for $40,000. 

Then he tells me "why don't you come to Denver and I will buy you a steak dinner and let you drive my Porsche Boxster" 

For the record, I was driving a 1997 911 Turbo then. I just sent him a photo and moved on. 

Wasn’t Danny of GR Research contributing to speaker design of some sort for them?  The audio circle forum is where I found some more info on them awhile back.  I have my old 750’s as my garage speakers now but those things have survived a few cross country moves and still sound great for what they are.  Too bad about the founder.  

Prior to this there was the Perpetual Technology 'thing'. I bought into the whole concept, dsp possibility for all speakers was going to be a reality, never happened. On the other hand, Dan Wright and my own diy mods brought that stack up to very high level of sound quality. 

Yes I owned the RS750 as well as the Ref1 back in the day.

As an owner of RS850 Sig, RS450 Sig and RSC200 sig and a long time (20 years) follower of Danny, I know quite a bit about it.

Dick Pierce was the designer of the hardware and original crossover of the AV123 Rockets. The crossover design wasn’t great and AV123 asked Danny Richie if he could step in and redesign the crossover.

This became some of the Signature series speakers.

The 850 Sig, 450, and RSC200 Sig all had a completely redesigned Danny Richie crossover that was known to be much better designed, had significantly better parts, crossed over lower which greatly improved vertical off-axis and didn’t have tweeter rolloff like the original had.

The 850, RSS-300, RSC200, 750 and 750 Sig always had the Dick Pierce crossover. The only difference that I’m aware of is the 750 Sig changed the tweeter resister value to one that wasn’t as rolled off as that was a big complaint at the time.

Here’s a little talk from Danny about them: https://www.audiocircle.com/index.php?topic=186471.0

I’ve personally moved on to another AV123 product and own a full set of 4 AV123 X-Static and a X-Voce center which were 100% Danny Richie’s design and he still stocks replacement drivers to this day. Most of the GR-Research X-Series was available from AV123 at the time https://gr-research.com/x-series-3/
