Adire Audio makes incredible drivers and thier pricing is very good.
Lambda acoustics made some of the best sounding equipment I've ever heard, I have still not heard a subwoofer that played music as faithfully as my PB15. Unfortunately they no longer exist.
JL drivers are top notch as well
I can only hope that Elemental designs will get a good review after I get my 16Kv.2 whenever they finally decide to ship it.
