tomlinmgt's QLS-1/Threshold/ARC rig

Awesome. My garage only has two cars, a garden tractor, a generator and three trash cans in it (plus random crap)

Garage system? Of course this is a garage system - in Texas! The 750-hp F-350 (for toting all of those amps to the re-cap shop) is parked just off to the left. Really.

Very, very nice! Room treatments - you mean garage treatments!

Thanks for sharing this with us :thmbsp:

HA! Yeah, there's a good number of those prowling the roads down here. Not me, though. But what I drive is a lot closer to what you suggest than say... something like a Prius. Gotta have something to haul the big speakers home, ya know. :yes:

My other garage has the garden tractor, lumber, air compressor, garden tools, random crap, etc.

Oh, and these little rascals (note the fiddle shaped marking on the cephalothorax)......

I suppose anyone who can use cephalothorax in casual conversation deserves a system like that! Nice system!

Right now, up here in Michigan, we can hang sides of beef in our garages... In particular, they work nicely as bass traps in the corners.

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.

I can't imagine doing a northern winter. Woke up this morning to 14 F.....if that lasted more than a few days I'd lose it. I'd rather have two consecutive months in the 100's.

Hey Michael, You need to post the updated pic. There is a lot more goodies in there now.

I'm thinking I'll just start a new thread that shows the progression of the room and rig with some of the different set ups I've had in the past and ones I'll have in the future. Stay tuned!
 
Michael , did you make the pads your Thresholds are sitting on ? Any magic to them I need to make a pair.

I did. They're simple boxes made from 1"x4" pine and segmented plank tops and bottoms with the cavity inside filled with cement and adjustable spike feet I made from all-thread (ground down to a sharp point) threaded into t-nuts. They weigh about 35 lbs each.

Thanks, Michael. Ummm, they are Marantz DS-940's. :yes:

Oh, sorry 'bout that. I'm admittedly not very well versed in speakers manufactured by electronics manufacturers. You could've told me they were JVC's and I wouldn't have known any better. :no: :)

Another approach is to use some thick maple cutting boards. I use that approach with VTL monoblocks.

Had I made mine with the intention of using them for amps I likely would've done just as you did, E-Stat....so take note, Steven. They were originally built as speaker plinths....but have since been recommissioned for the amps.

Yeah, neither am I. :tongue:

The ones I am particular about are the ones designed by Edmond May while he was employed by Marantz. They were produced in very short order in limited quantities, so it is very much like a non mainstream type of design.
