250Ti LE14H-1 Replaced by LE14H-3

[varice]

Question - has anyone replaced an LE14H-1 with an LE14H-3 in a speaker system?

Are you happy with the results?

Hi,

If you havent seen this thread already, take a look. Seems to be an OK substitution.

In answer to your question, I m not sure if anyone on this forum has actually tried it out yet. If I had to, I would do it myself though.

Did you find any change in the woofers?

No report, taken.

I have 1 thread where i reported and have also talked about it in Andy's thread, try the search feature.

Sonicaly so far seems the same maybe punchier but it also could be what we want to hear. also note that an old speaker was replaced by a new one no matter what model when making a comparism. you need 1 of each both newto compare them directly.

Before I did the switch I was told by someone that GT said he would do the switch himself now, he had no fondness for replacing foam (something close to that)

Harmam Audio has LE14H-3 drivers (336321-001) available for $279.93 on the parts website:

I ordered and recieved a pair back in November. Also got the longer mounting screws (804-01110-24), but they did not have the gaskets (354680-001) in stock. I plan to keep using the LE14H-1 drivers currently mounted in my 250Ti system, they should have a few more years left in them before the foam surrounds give up the ghost. Hopefully, I should be able get a couple of the proper gaskets by then.

A recent post elsewhere here on LHF prompts me to suggest you take those drivers out of the box and test them before you lose the warranty.

Yes, I did give them a lookover. One has a banged up ID plate on the back. A DC resistance test measured about 6 ohms on each, about what I would expect. Then ran a test signal to check for any other problems. They seem to be 100% functional.

I replaced one LE14-1 in an older pair of 250Ti's. I lam very pleased. I want 3 more to finish out my system (I have 4 250Ti's, but JBL does not appear to be making anymore.

they are listed on the webpage, but if you order them, they bill your crdit card and you are on backorder until you ask for your money back. I had a very disappointing experience which I will not detail here.

JBL left the loudspeaker component business in the early 80's. Since then various drivers have been in stock only for replacement purposes. Alot of the older drivers became NLA as stock ran out and replacement runs were never made. Sometimes we have to wait up to eighteen months for our orders to be fulfilled.

It will be interesting to see if this is rectified with the closure of the eastern campuses.

Just small question.

What is the diameter of the 14" woofer in the 250Ti, in metric please.

Is it mesured on the cones outer edges, or the foamrings, or the outer edge of the mounting frames widest part?

My 14H-1 is 35.5cm from corner to corner, measured across the screw holes. Inside the flange, (outer edge of the gasket), is 30.5cm.

JBL calls it a 14" 360mm driver, FWIW.

(Though 14" = 355.6 mm)

[Dr Tinnitus]

Ok, according to the two latest replies my 14" is the same. I just started to wonder, because if you measure the actual cone diameter with foam ring, it's not more than a 12" woofer. But if you measure across the frames edges on the widest part, is 14".

I don't really like that kind of tricky way to boost a woofers size. You can if you like then have a 4" cone with a 3" wide mounting frame, and call i a 10" speaker....
