I don't own this sub, but am very close to buying one (probably three). With that prospective purchase in mind, I thought I would start the official thread (my 9 to 5 job remains terrifingly quiet).
A few initial thoughts as a non-owner.
1. Hsu is general, and the ULS-15 in particular, does not seem to get credit/respect in these forums compared with SVS, JL Audio, Submersive, etc. Any thoughts on this?
2. I think the ULS-15, but also the Rythmik DD15-SE (and Sunfire if you can accept a smaller driver) monopolizes a high value, high quality niche of strong SQ, premium finishes, reasonable size. The commercial competitors:
A. JL Audio Fathoms, Earthquake, Velodyne - More expensive
B. SVS - Larger
C. AV123 - Having organizational issues
D. Seaton Submersive, Epik, ED - No premium finishes
Any thoughts on the ULS-15's place in the market?
