Port tube availability ?

[buzzmarr]

I was wondering if the port tubes for a set of 4311b's were still available retail through JBL? And isn't there a tube behind either the tweeter or midrange as well? My memory is fading! Anyway, same question as above for that tube also. I have the drivers, am missing ports and need to make some cabinets to get these things in use again. I looked on the web site, but might have missed it as I didn;t see anything. Thanks

Neither the port tubes nor the subenclosures have been available through JBL. You can find the port tubes on eBay.

The subenclosures can be made from 5" or 6" diameter tubes so that the internal volume is ~ 80 cubic inches.

JBL often used the following dimensions for their subenclosures:

5-5/16" internal diameter x 3-1/4" depth
5-11/16" outside diameter x 3-5/8" depth
recessed into 3/4" thick baffle by 3/8"

The subenclosures can be made from 5" or 6" diameter tubes so that the internal volume is ~ 80 cubic inches.

Yea, buzzmar -

I don't know where you're located, but if you're needing some lengths of that 6" tube, I've got ample left from prior DIY projects. Lemme know...

Any good ideas on a good substitution? Are the L100 tubes (or any others) and the 4311b tubes the same. I am trying to match my other set of 4311b's as closely as possible

Thanks

Ok, I lied.

JBL appears to have some left and is willing to sell them regardless of the "Not for Sale" notice.

Have your favorite Authorized JBL Service Center order you a pair.

Part number is 52211.

JBL is so weird...
