As I move forward with the complete renovation of my (infamous) 4325's, I now find I have a couple of 2216's kicking around in pretty good shape. I figure Giskard would suggest that I pitch them into his local lake, but being an optomist, maybe they could rise from the ashes and be morphed into something else.

Anybody know what they could be turned into? 2215's maybe?

p.s. - In water tight plastic bags please along with a gps beacon. ;)

Sure they can... what are you trying to do? I mean what is your goal? Do you want the best economical solution from a performance stand point? Do you want to restore them as vintages pieces?

For performance I would sell off the 2216s and get 2235s. This will require entirely new networks. You can recone the 2216s as 2215s and they will be better, but 2235s are better still and less costly.

If you are after an acoustic match for the 4325 and your 2216s are not operational you can pick up LE15Bs pretty regularly.

I already have four 2235's, I was wondering if there was a list somewhere that allowed a choice of possibilities. The motors and cones and surrounds are fine, I just doubt that anyone would be interested in them. So maybe I could turn them into something useful.

The 4325's are now S-22-2's, I no longer will need the 2216's.

Actually, I have access from below of my HT system and I was thinking about bolting them to the floor joists and feeding the sub signals (<40Hz) to them! Might be fun.....:dj-party:

Even though the 4325 has a checkered reputation at best, it has one advantage - extreme rarity. The LE15B is common enough, but 2216's almost never show up. I would keep the drivers as is. If you want to use something else, pick up a pair of 2215B/LE15A's or even 2235's. You can generally get these for not much more than the price of a recone. If you ever want to get rid of the 4325's, you can put back the original drivers and sell them to Japan for significant $.

The 2216/LE15B and the 2215/LE15A are the only two drivers made from that frame and magnet.

I would not ruin a functioning 2216 to make a 2215.

The 4325's are now S-22-2's, I no longer will need the 2216's.How are the S22-2's? Are they as horrific as someone else posted in another thread? What are your specific components in that system again?

Don, the 4325's were pretty badly beaten up. They now sport integral bases and with some filling, sanding and melamine paint they are quite cool in my listening room, but they never were candidates for restoration - at least within my meager woodworking skills. I'll try to post pics again when the LF portion of the system (see below) is complete.

But, they made an excellent platform with suitable bracing and reinforment, for the S-22-2. I installed an alnico 2235, 2441/2311/2308/2405H. They are currently biamped at 100 Hz to four (two per side) Altec 414z's (soon to be four 2235's and later a pair of sub1500's for kicks). Giskard, you asked, how do they sound?

Bloody AWFUL! I couldn't live without them. :) They simply reproduce sound as I think it should be.

My original, stock and untouched 4430's can't approach them for now.......I am eager to change diaphragms and update the xovers and do a head to head comparison.

Speaking of this, I was asked about something very similar recently...

Just to be sure... this is the relationship I think I remember, but just wanted to make sure it's valid:

2215 == LE15A

2216 == LE15B

2215H = LE15H

... at least as far as factory recone kits are concerned, right?

Regards,
Gordon.

Yep.

2215B == LE15A 2215A is an 8 ohm version (not to be confused with an LE15A with 8 ohm foilcal)

2216 == LE15B

2215H = LE15H

I now have an unused pair of LE15B's from L-200's. Many posts here say that the commercial equivalent is the 2216. In looking at the spec sheet for the 2216, it says that the impedance is 4 ohms, but my LE15B's say on their label that they are 6 - 8 ohms. Does this matter?

Your LE15Bs have the same impedance "curve" as a 2216. In the past JBL has been a bit arbitrary with their printed impedance figures. It has been suggested that the confusion arises from different intended uses for the drivers... I suspect it was more marketplace driven.

The impedance number given for any speaker is a bit misleading. Other than ribbon drivers, most all speakers have quite a range of impedance values depending on frequency and the simple number printed on them is really only a guide.

I have never measured the impedance curve on an LE15B, but if I were to design a passive network for one I'd measure the impedance curve first.

As for the 2216, that was the Professional Series designation for the same woofer. I would guess that JBL sold more LE15Bs in their L-200 systems than they ever sold 2216s as raw drivers or in their 4325 systems. In any event the LE15B is a popular driver on the used market, if you don't have any plans for them you might consider selling them. They are popular in part because their surrounds do not rot like the foam surrounds do. Of course they don't perform the same way as drivers with foam surrounds either.
