Well either Jimi or Stevie Ray Vaughan Yeah, she could use a little work, but the friggin' guitar is bigger than she is. If she keeps at it, by the time she's grown she'll be bigger than her axe and grinding the heck out of it. http://youtube.com/watch?v=p1OJc3Cg1c4
I propose we use this Thread to document some of the references that we find pivotal, with a brief mention on why. There are some references I know got buried out in the ether, and I will go find 'em and get it all here. :coolness:
Thiele-Small Parameters B Magnetic flux density in gap, in Tesla-meters (TM) BL The magnetic strength of the motor structure. "Expressed in Tesla meters, this is a measurement of the motor strength of a speaker. Think of this as how good a weightlifter the transducer is. A measured mass is...

I'd like to hear from others about the methods used when measuring a driver's Fs and for calculation of Vas, specifically the mounting and orientation of the driver being tested.

Hi, I am a newb who just purchased a pair of N2400 JBL crossovers in an Ebay auction. I have read that some of these crossovers are either 8 or 16 ohms, most of them being 8 ohm? The question I have is when I go hunting for other components that go along with these crossovers. I see many JBL...

My friend here in the UK has a pair of mint JBL 4355s but on long listening sessions I found the quite fatiguing compared to my 813Bs what is your opinion of these speakers? They were tri amped with the appropriate crossovers. Dave
I had not heard of fraziers until a couple of weeks ago. The model 7 grille is much like the L100. Made this sample for someone who furnished a picture and the outside dimensions of the grille. The actual grille is twice as tall as this sample. He told me the Frazier Model 7was designed by...

How does these RCA Mi9584 midrange drivers compare with western electric in sound and is it possible to convert these to field coils
Has anyone had any experience with these "Class D" amplifiers yet? I've read conflicting reports, particularly about the XTi1000, which has a very attractive price, and I gotta say, at only 11 pounds, the weight seems quite reasonable. On the one hand, some tests have claimed the amp lacks the...

Hi, My audio gear is 4343, with Mcintosh C29 preamp and Marantz power amp. Initially I didn't notice this, but as time went by, I suspected some sort of difference in loudness of the right and left speakers. And only today I concluded that the sound from the left speaker was a bit louder and...

What is it about the "Significance of a Screen Name" that caused it to be a closed thread? :confused: I guess I've missed something?:blink: Thanx
In my search for the required hardware to reach audio nirvana I found this! I'm sure many of you have seen it before, but, no one ever talks of hearing one and I believe I have found out why. Now its obvious that you must drive it with something and after reading the whole sheet it is more than...
Hello everyone, I need some general information, and user experiences IF anyone has on Parasound amps. Basically, what I am doing is seeking new amps to run all my horns and tweeters, I am also upgrading my sub bass and midbass amps, and I will remain Crown powered for all my woofer needs....
Recently installed 4 brand new Infinity Kappa 6x9 in my truck. The other day I hooked up my Pioneer CD player that I have had in several cars over 13 years. And I've always had different versions of Infinity Kappa 6x9s hooked to it. They sound pretty good compared to factory speakers with the...
