Synergistic New Tesla Line...Any comments?
Of course. With the pyramid upside down, standing there on its little point, the shielding is sure to become unstable, eventually toppling over and ending up, oh, I'd say about 120 degrees out of phase. I would not expect a hum, though. Maybe a li... 
Synergistic New Tesla Line...Any comments?
Karelfd, the wall wart in the MPC is just a garden variety 300mA 24V transformer that you can buy for about $15 online. I've had a couple of them burn out, and after once buying the real deal replacement for an idiotic price, I just replace them b...

Consider also Dave Alvin, Robert Earl Keen, and Lyle Lovett. 
Divorcing..Splitting the cd collection..
"I can't imagine any court ruling that one party should keep both copy and original because of copyright infringement."One does indeed need an imagination to conjure up a scenario where a court would get involved. However, even though it is almost... 
Andra II speaker tilt/effective tweeter height
Kurt, I am biamping with two BAT Vk600SE amps, each configured with a bridged input so I need onlya sinble interconnect to the amp. BAT Rex pre. Sometimes I switch in Krell 750s, but they work poorly with the BAT pre, so I use an EMM DCC2se as the... 
Andra II speaker tilt/effective tweeter height
Perhaps the angle has something to do with time alignment. I do not know. But there are two indentical midrange drivers, one above the other. If time alignment was an intended design element embodied in the tilt of the speaker, wouldn't these driv... 
Andra II speaker tilt/effective tweeter height
It was surprising how high the tweeter was aiming when I checked it by placing a laser "tape measure" flat against the tweeter surround and noting where the light hit a target at the listening position. To get my head up there I'd have to sit in a... 
High density fiberglass as bass absorber?
A veritible goldmine of useful information. Now I retreat into my cave to see if I am able to utilize it effectively. Thank you Shadorne! 
High density fiberglass as bass absorber?
That looks like a real effect. A bit unpredictable maybe, but real. Any idea how dense the insulation was as packed into the tubes?I will stack some bags iof this Atticat stuff into my window dormers, measure the low frequency levels in those dorm... 
High density fiberglass as bass absorber?
The wrong "kind"? Knowledgeable people have recommended simple bags of rolled fiberglass insulation (thank you Ethan Winer). I find no reports on using this particular Atticat product or any other fiberglass of this density (if indeed there are an... 
High density fiberglass as bass absorber?
For present purposes I have no concern about reflections from the bags. FWIW, some very effective bass traps (e.g., realtraps) do not have any defined inner space, but they are said to work better with open space behind them. And they have a refle... 
High density fiberglass as bass absorber?
The product is a bag of fiberglass, pretty tightly compressed and intended to be taken out of the bag and spread in the attic. No foil or backing. Its not a sheet or a roll or anything like that. Its unique feature is the high density as packaged.... 
Listening chair suck-out
Yeah, I can swap chairs. My room is dedicated, so I can do whatever I like. For now I an going to use a little wooden rocker that I have always found very comfy. I hope those of you with SPL meters have an easier time than I in dealing with the re... 
Listening chair suck-out
Porcelain! That's it! It would go well with the magazine rack, and the back doesn't extend above my shoulders. Most significantly, we all know from experience that those things don't absorb low frequencies! Yeah! 
Thoughts on attenuating 1/4 wave cancellation
The deployment of the speakers and listening position is constantly varying, so I hope to keep the discussion general and related to the possibility of soaking up low frequency bass backwash. Will that generally work, or is there some flaw in the ...
