Anyhow, what are the 2" comp drivers that ARE any good and are available comercially? I didnt go with any JBLs because I had a very bad time with the 2427 1" version, could never get any music out of it.

I would be surprised if you get any reasonable sound out of 2427 driver. I do not had it but I true a number of the drivers from the same family. My observation is that those drivers with small cones are very-very poor, unless you use them somewhere above 3kHz, but still the do very bad sound. The 1” Altecs were better, the older 802 or 808 with the 802 cones (not with the 808 cones). Still the Altecs were slow and had very small/ stiff-suspended cone to sound reasonably. The large Altecs were more fun and the 2” JBL were way more sophisticated, particularly with put aluminum cones. You might try the 2440/375 but do not bite into the newest titanium diaphragms. With all cones and pros of 2440 they will have VERY different sound then even a dozen BMS drivers. BMS juts do not go where Sound lives and no foam will help them. The entire reputation of the BMS driver is based upon the hype that a half dozens of idiots- manufacturers blow up abound the BMS driver but in reality it is all very-very third-rate drivers and any single product built around the BMS drivers is a testimony of nothingness.  You might stop by in your local pro audio shop and lease for a weekend a speaker with 2440/375. It will cost you ~$60 over a weekend. At home you would need to clean and to align the driver and give it time to play. It will be very different then JBL one-inchers. There are other options but it is would be an easy way to learn how much you do not get with BMS....
