I order the ULS-15. I hope it is as good as all the hype. The goal was to get tighter bass from the sealed box. I don't really expect to be pumping out 100dB of subsonic rap music or techno...Sure a few slams of movie soundtracks will be nice...But I have a hard time thinking I'd want more bass. It will arrive sometime next week. I'll post an incomplete first impression review and then a full review when I integrate into the paradigm speaker setup. The dealer had to order the speakers. I might even see if the dealer will let me bring the woofer to the show room. We could compare it to the 1400$ Paradigm Millenia Subwoofer. I saw the Millenia sub in person and it looked dainty...The woofers were oval shaped. It didn't strike me as a 1400$ subwoofer...I mean the cabinet didn't even weigh over 100LBS... I understand the appeal is a compact easy to place woofer but if it won't deliver the goods what's the point. We'll see. I really don't want to knock the Millenia Woofer. I liked the Millenia speakers so much we ordered 5 of them for the theater setup. I just couldn't see how a tiny woofer like that could perform as well as the HSU. We'll see. Also I didn't like how Paradigm charged an extra 120$ for the wireless accessory and then another 300$ for the bass optimizing software...Can't a guy just use a good old fashioned SPL meter and a make and make some adjustments?
