Guidance on NHT 2.3A Driver Replacement

[ChrisKandor]

Hi, I'm new to the forum and want to replace drivers for my NHT 2.3A's. I've done some initial reading and visited home.comcast.net/~jhidley/ and see I may be able to find some of the replacement drivers for this pair, but I am not sure of the available stock, what is going to work. NHT's support can sell some tweeters, but without the mounting plates and nothing else.

A couple of things perplex me. (1) I've seen that my actual part numbers on my set don't exactly match what I've seen as replacements for a 2.3A, from resellers or other sources and (2) I can't find a definitive spec on the 2.3A to tell me what to match (for ex. Hidley does point to a replacement but his npt-11-010-1 looks like a part match for my tweeter, but that 6.5" size is definitely not my 93mm dia. tweeter). If it matters, my Left was made October 1994 and the right September of 1995, they both say Model 2.3A, Min. 30W - Max 200W and 8 ohms.

Any advice would be appreciated to restore these to close to original working order, ideally with an OEM driver replacements if that is practicable but something that makes sense if not an original match. Here is what I have as stamped on the drivers:

1. Definitely need to replace both tweeters; the part number I see on the back is 1-010-01 with "841TND" as another notation. These are 3-screw mounts with NHT on the front, I have only 1 of them but may be able to locate a used replacement. (if the attachments work, they are pictured).

2. Definitely need one mid-range, the part I see is 1-11-019-1 with "651TF" under it.

3. Would like some guidance for a replacement on the woofer Part 1-11-017-1 and "753TNE"

I really appreciate anyone who knows and takes the time to offer suggestions, so thanks in advance.
