Has anyone had a chance to audtion Audio Pro subs? I've heard from many retailers that they are very excellent subs and along the same price range as Polk, AR, etc. This kinda came as shock to me because I've never read or heard of Pro Audio before until this week and I've been subscribing to most of the audio/video magazines for the last 5 years or so. The word is that they offer very tight bass which is so what Im searching for because I have had it with loose/muddy sounding subs during music sources. I would greatly appreciate any feeback on these puppies.
