Thought I'd share the latest incarnation of this (garage) rig as it's performing at a fairly high level compared to what I've done in the past.

So you went ahead and got another Threshold, very nice!

What a great view, must be an even better listen.

Tom, you have just about the opposite of everything I have: Lo sensitive speakers, big amps, SS, many drivers, complex crossovers. But if I've learned anything in this hobby it's that there are many different ways to make a good system.

I bet it sounds great. Looks mighty impressive as well.

Thanks for posting and enjoy!

Well, if someone would hook me up with some SET mono's for my Altec 19's (some Bottlehead Paramours would do just fine, if you please) I could walk around in your world a little bit. I'm all about sonic exploration. :yes:

And thanks for all the compliments, guys.

Very nice my friend.

But where are your H-frames?

Oh, just temporarily sidelined, Paul. I'm chompin' at the bit to get em out again. I sold the Alphas and need to beef up the "frames" as I want to try a few of these AE IB15's I picked up in them. MJK's been having some success with them but the slope in my plate amps isn't what he recommends. I have a dbx Driverack PA+ that'll take care of that but before any of that happens I want to finish the restoration of these IRS Betas I've been working on since Feb.
