Default Radio Shack 1272, anyone?

I was wondering if anyone has ever used this speaker in a project. Its sort of like a slightly higher power 1271 without the curvilinear cone( instead, its a more conventional shaped cone, and a more aggressive whizzer). I've used these to restore old console stereos when a good vintage speaker was unavailable. They don't sound too bad in this application, and I'm wondering if anyone has used them in a project.

I've bought a bunch of the full-range Radio Shack 8in. drivers. And, so far, I've liked the 1272(D) the best. I've used them on a set of large open baffles and they sound REALLY nice. I've just gotten a set of 1271C's, and have read that people have really liked them, but, don't have the time to try them out.

the 1271c ( which btw is my avatar) is a nice sounding speaker as well.

It seems to hold the bass notes a little longer, while the 1272 seems to have a stronger initial punch to its bass notes.

I have all three of the rs 8 inch fr speakers, the 1271, the 1272, and the 1043( though it seems the model varies on this last one. theres also a 1286 that seems to be the same as the 1043) and two of the Wall mount PA speakers, which is like an "instaOB" when use un-mounted. It sounds alot like the 1271, but the driver lacks a whizzer.

I think I have all the same drivers :-) 1271C, 1286A, 1272D, and 1044(poly prop cones, foam surrounds). I just swapped out the 1272's for the 1286's (they have blue paper cones with black whizzer) to see how I like them in relation to the 1272's. I didn't care for the 1044's but, maybe I didn't let them play long enough.

the 1286/1043 seems to be a heavier duty FR that seems to have the underpinnings of a woofer. Its bass is superb, yet it still retains alot of its highs and mids. It seems to be made for medium powered amps, while the 1271/1272 is made for lower powered amps.

I played around with the 40-1271 in an open baffle. The results were ok, but nearly as well refined as a Fostex driver. I found them best suited as the mains or rears in a HT setup with a sub. The problem I had with them is that they start to beam at higher frequencies.

Greets!

In 2001 someone sent me a 40-1242 FR plot, but don't recall if it was an 'E' or not. Anyway, it was so bad that I had no interest and I don't recall him doing anything with them either.

Yeah, I've irritated more than a few folks on other forums when I remarked IMNSHO that a particular driver be used for skeet practice since invariably someone was either pleased with its performance or they had already bought some on sale.
