Do you have some 1400nd woofers?

Do you have some 1400nd woofers?
The first phase I will use a pair of 136A (2231A) 15" woofer for DIY S7500, HF driver is 2420 or LE175, 85. The second, I will upgrade from S7500 to S9500 by adding a bass cabinet (using 2215A 15" bass driver only) on the top of S9500.
Please giving me the drawíngs if you have.
Thanks

The S7500/S9500 woofer enclosures are too small for those woofers.

We don't have the drawings, as far as I know. There are cutaway sketches in the manual, and I understand the size as about 2 cu ft each. The boxes are even too small for the 1400nd. For that woofer you would want to use the volumes of the M9500. The upper box is 2.8 cu ft tuned to 32 and the lower is 4.1 tuned to 28, as I recall. Do a search for the M9500 if you are interested in building enclosures for the 1400nd.

I don't know why you call this project an S7500/9500 K2 clone. The only similarity I see is that it is a 2-way.

You should be building enclosures for the woofers you have, which are quite dissimilar to the 1400nd and require entirely different enclosure planning.

I suggest you do some looking around the resources here on your own. Familiarize yourself with the library. Learn how to use the search function. Read for a couple of weeks and orient yourself a little bit. Find JBL Pro, look around. Find JBL Home at Harman International, look around.

Thanks for your good idea.
I 'll do some looking around the JBL resources and finding out the new ideas for my DIY project.

thanks for that!

I've read the posts and there's no detail parameters I needed for S7500 bass carbinet cloning, I do find the one for M9500, will make the cloning by a little changes on M9500, hopefully work.
