hsu uls-15 mark ii vs Velodyne Optimum 10


I have an opportunity to buy either of these for about the same price. The HSU is a 15" but actually rated lower in power than the Velodyne.  (2000/600 vs 2400/1200). I believe both are sealed type. I will be using for music, not HT. Fairly large room (16x22 with an open entranceway) Any thoughts.  Thanks.

Bot,
I have a pair of HSU ULS-15 (1st generation). I can tell you they do not lack for power in my 14'x 36' living/dining room which is also open to the rest of the house (kitchen/loft/hallway, cathedral ceiling, etc).

I moved up to this pair from a pair of SVS SB12+. The SVS subs integrated better with my mains, but did not have the output required for my space. The ULS-15s go low with authority. I had some peak issues at certain frequencies with the ULS's and now have excellent integration using an SVS AS-EQ1. Probably one of the best (least expensive) pieces I've added to my system. Easy to set up and with great results. If you have room in your budget and can find one, I highly recommend the AS-EQ1 (you will need an old Windows laptop to set it up, I picked one up for $50 on my local CL.)

The ULS-15 should have plenty of output in your current space. Looks like the Velodyne has auto EQ however, which is something to consider if you're not a tinkerer.
The service at Velodyne for me has always been 5 star. Have had my HGS 18 in twice over its long life and have been very happy with the service.
enjoy Pete
