So my in-laws just gave me a pair of 240ti's from their storage unit. Cabinet condition is great, but after removing the grilles I see that one of the 14" drivers needs a refoam and the other is missing all-together. Is there a comparable driver to put in their place, or are there replacement drivers available?

thanks in advance

I would search ebay and craigslist for JBL LE14-h1 that is the component name for the woofer in the 140ti. More often than not you can find them in good original or reconed state for very little money

see the manual for the 240ti : http://manuals.harman.com/JBL/HOM/Technical Sheet/240Ti ts.pdf
+1 on this. You DEFINITELY want to put the original driver back in there, if at ALL possible. These are very elegantly designed, high-performance speaker systems... IMHO, one of the top five things that Greg Timbers has designed while at JBL.

BTW: The same woofer is used in the 240Ti and 250Ti. So, that can broaden your search criteria a lot.

BTW^2: In worst-case conditions (i.e, you never find a LE14H-1), the LE14H-3 (as used in the Citation 7.4 subwoofer) can work as an acceptable replacement, according to comments I've seen by those who have directly compared the 'H1 and 'H3. The only serious difference is the use of a rubber surround on the 'H3, as opposed to foam surround on the 'H1. IIRC, the LE14H-3 is actually still an available part from JBL parts. You would DEFINITELY want to replace BOTH woofers in the pair, to make sure that the cabinets sound the same, if you did this...

Gordon.

Oh, one more thing that came to mind- an earlier JBL LE14-H (white cone, ceramic magnet) CAN be reconed with the cone kit for the later JBL LE14H-1 (black cone). This will make an exact functional match to the original. A good reconer should be able to do this for you. In fact, while the cone kit is out (before the new one is installed, you can paint the edge of the frame black... so, it should match the original one in cosmetics...

To be clear- that's the JBL LE14H... NOT the JBL LE14A with alnico magnet. The 'a' version with alnico magnet (rounded "pot" magnet) has the wrong magnet geometry and strength, for the new kit to work properly... but, the 'H' version with ceramic magnet is fine.

Gordon.

I would definetly lean toward the ebay suggestion. I own a pair of 240ti's purchased new and I still think they are great. I've noticed the woofer does come up from time to time on ebay... I've thought about buying myself a spare.. as I plan on keeping my old JBL's for a long long time...

Be happy your not looking for the tweeter.. those are spending even on ebay.

Just FYI... there are two of these drivers on Ebay right now. If you type jbl in the search, and then select vintage electronics you will find them. Looks like one is reconed, the other not. Same seller for both of them...

Thanks for all of the input y'all, I've had to put the 240's on the back burner temporarily. Had an unexpected (read unwanted) trip to the in-laws that came up. Also, when i do get another LE14h, does anybody know of a recone service in Houston,Tx, or are there reputable places that i could ship them to(i.e. partsexpress)?

thanks again y'all

Both of my 7.4 subs have the LE14H-1 in them.

This is the correct repair kit for these speakers. Midwest speaker repair are the best outfit to repair those speakers. You can buy the kits or send it to them if you do not feel comfortable doing it yourself.

You do need the dust cap and shims or you will not get the VC centered and you will have gap rub. This is not difficult, but you have to be precise and careful.

You need to remove all the old surrounds and glue. Then you cut out the dust cap. Make sure you cut it out on the inside of the VC former. If you do it on the outside you will ruin the speaker. Then you place the shims between the VC and the pole piece, to center the VC. Now you glue in the new surround with the provided speaker glue. Leave it overnight. Then remove the shims and glue in the new dust cap. If you do this carefully, then your speaker will be as good as new.
