Hello, I'm interested in buying an Audiobahn ALUM15X from this site for less than $150 shipped. I picked this driver because of its Tempest like qualities, low Fs, low price, and high Xmax. However, I'm worried that the listed specs are maybe not up the Dumax standards. Could one of you who has some knowledge or experience with these drivers please lend some advice? Thanks, Duane P.S. Any Crest LT owners know if those particular units are capable or bridged operation into 3 ohms?
