>>Matress foam, maybe? I would GUESS that kind of foam is CLOSED cell ?? I would not bother with the tape/glue ... it's the 4 bolts that hold &...

Hi, and thanks again guys :)! Good idea, I must have some old foam somewhere. Matress foam, maybe? Next one I'll use less/narrower leverage and...

Good catch Dagfinn :)

looks nice ... for foam, I just went through old packing boxes and found some pliable, but firm open cell foam that was older, but didn't seem to...

Ok, after being lost in the Postal system, the 044Ti arrived today, and I just couldn't wait :bouncy:. It got a sqeeze during shipping, poor...

Hi Anti K, May BMS 4540ND would be OK http://www.bmsspeakers.com/index.php?id=bms_4540nd or Ferrous 4538 ...

Turns out one of the switches wasn't fully engaged in a position. Once I cycled those a few times on the K2, all was well. You were right about the...

Thanks for posting. Please, where can I find these specs for JBL drivers?

As for the left right issue what happens when you swap the cables at the input to the amp?

Low serial number??

I think those are pretty cool , the birth of a legend. Easy to make look tidy if the drivers are A1 ,, why not ?

JBL number starting with 45 is the enclosure.

Thanks for your input Mike, much appreciated. Oh, I did not know that about the fans. Yes, each fan was caked with dust. Although perhaps...

Just measured L19 speakers with DMM. They are 5.7ohm and 5.8ohm.

Can't say if what you measured is correct or not. But the 8 ohm spec is a NOMINAL figure only. Its not unusual for speakers to actually measure lower...

Hello all! Just a short question about L110A. Today I measured with DMM the resistance on speaker terminals. One speaker is 5.1ohm, the other is...

I always wonder when I see this load quoted if you don't really mean 130A. I know there actually was once a time when dinosaurs ruled the world but...
