I worry about companies that have lessened in quality to make ends meet. There are companies who are falling by the wayside on a regular basis. And some of those companies are very big.

I don't know about the LF drivers you are looking at. Altecs lineup of 416/515 were their bread and butter series, but required large enclosures(416 - 8.5cu' - tuned to 28hz), and the 515 is even more of a midbass driver. Not a prob if you have a sub underneath.

Other topic here. I finally got my 2242H 18" JBL sub-woofer installed in a 8.8 cu ' box tuned to 28hz.

WOW!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Talk about moving some serious air!!!!!!

I have only hooked it up to test it out(heavy bass music-no mid or tweeter or crossover, just straight up to the amp).

Can't wait to integrate it with my 2226 and 902 on Edgarhorn(650hz).

My crossover is your standart 4 Pi-pro with .68 ufd MPP caps bypassing the caps in the PE 1.6khz hi-pass crossover.

Took some time to burn in the new crossover(drivers are already burned in). I think it will still smooth out with more time(only have 14 hrs on it so far).

By the way: Altec 902 beat out the JBL 2426 in my un-official shootout in my home. The upper HF response was much superior.

Time to quit wasting bandwidth now!!
