Thielrules - it all depends. A very big deal is running out of power. The Adcom and Benchmark have overload LEDs. Listening at 95dB peaks at listening position, the Benchmark overloads consistently in stereo with one amp channel driving the woofer...

Unsound - I agree to wanting 4 ohms minimum which would roughly double the impedance of many Thiel models, making them far easier loads to drive with lower amplifier distortion and fewer cable interactions. Jim committed to underhung voicecoils as...

unsound & thielrules - about individual amps. I’ve been comparing configurations these past few days and conclude that it’s very murky water. I have matched pairs of Adcom GFA-555 mkII, Classe DR9 and Benchmark AFB-2s. The power is similar, bu...

Yes, the side and front wall reflections are quite important. Your room is quite narrow, since the polar pattern of the CS3.7 is quite omnidirectional. Can you try putting them on the long wall?

Yyz - the definitive test is to make a momentary connection from a 6 volt lantern battery (or other 6 volt DC source) to the XO inputs. All drivers should move forward. You can readily see the woofer and midrange move, but may have to feel the twe...

Keep the time domain in mind, especially for phase coherent speakers. On and off axis radiation patterns are different as the frequency rises. The speaker is balanced into an "average" environment with assumptions made as to where the front and si...

Unsound  & yyz- thanks for the catch. Seems I am confusing my stories. The 'cubed' feedback stands as exceedingly complimentary; but I don't remember from what source.

As a point of Thiel history, Jim used very good amps to design the speakers. His attitude was that making a good amp was the ampmakers’ business, and making a good speaker was his business. We generally had on hand the best from Levinson, Krell, A...

I really appreciate amps with clipping indicators, since there are so many variables of room, level and loudness preference - it's hard to predict amplifier power need; except that more is better, but usually at the cost of sonic finesse. Rules - ...

Hello all - back from away for a few days. Jon - was it you looking for grille fabric? Rob at Coherent Source Service has original grillecloth. Note that it got more sheer over time, so you might need a matched pair.Re amps: What a trip - I have s...

JAFant - thanks for the cable tips. Too many variables, too little time.I have direct experience with Mogami from the pro world. It's considered by many pros as best of form for mic, interconnect and speaker cable. Their best is quite good, but di...

thieliste - what's the price tag?Anybody tried the new PS Audio 1200 watt monos? They state 2ohms as suitable for musical transients, so I donno.

YYZ - what a system! Thanks for chiming in. I landed on Benchmark for my use and love it. thielrules is correct that low impedance loads are harder to drive when bridged. John Siau, the designer. evaluated all Thiel performance curves and chose on...

Regarding the cracked concrete baffle. The chicken's way out (easy and little danger) is to smear concrete caulk on the inside to stop the airflow. Then dribble thin epoxy or cyanoacrylate into the crack from the front and either finish the show f...

Unsound - I agree that the proper rating for the 3.7 would be 2.5 ohms. Nominal impedance is by convention stated at or near the minimus after the bass anomalies. If that trough is deep and steep the rating can be upped a little, but the 3.7 does ...
