I paid an "Authorized JBL Pro Repair Center" to "fix" the same problem in one of my 6260s. They recapped the low voltage supply. The amp ran "back to...

Colleagues, Here are a few thoughts on the degradation of pop culture music. I believe that Rock music as an art form, reached its zenith between...

There are two well known bass players involved in these recordings: Wilton Felder and Carol Kaye. Inner sleeve note of the musicians credits: "Base:...

It has been a while since I have torn it apart but IIRC the motor is hard mounted. Here is a pic; I was thinking of trying a 3 axis...

A fine one. Sonny Landreth, guitars. Listen to the swinging "Who, What, Where, and Why?" B5!

That makes sense. Maybe if the drivers are run on a sine wave at 30 hertz for a reasonable period they might loosen up. You can down load an...

Me too as well! Same with me lots of vinyl where I am with the CD's. I do a lot of small venues close to NYC and some of the bands I see for a $12...

Allison Miller, Yoko Miwa, Jenny Scheinman, Janel & Anthony. Most recent stumbles. Random visits to small clubs in the area. I like the fact...

A little bit too much sugarcoating with strings&horns by Bob James. Typical of the late 70ies. But overall its good STUFF. Listen to the beautiful...

well, i think that its better if i stay with my regular amplifier setup... i think its not worth the effort and the money.. thank you anyway for ur...

Just a cautionary note: I can't say for the black cones, but the 128H white cones do come in two different sizes. Rick Cobb will have you measure...
