My initial impressions of the Emotiva Ultra SUB10.
When I first got this sub, the first thing that I noticed was that absolute amazing build quality. This thing is a 12 inch cube and it is no light weight, at almost 40 pounds. The grill is very heavy for its purpose as it is made out of wood. How often is subwoofer grills made out of wood today? Very impressive. The grill has metal pegs that will not be moving anywhere, it is secure. With the grill on, the subwoofer looks nothing special. Once you take it of though, you can see the beast inside. The subwoofer it self looks very good, nice and clean. The amp on the back looks top quality.
Enough about looks though, lets talk about what really matters. After the sub crawl and calibration it was time test it. I popped in a Live John Mayer DVD and this subwoofer came alive. Bass lines were well defined, drums were hitting hard. This sub is very musical and gets quite loud. Then it was time for raw bass testers. These are mostly just bass sweeps, but they are actually decent songs. The SUB10 does not disappoint and hits every note with authority. The most challenging test though, was Bassotronic's "Bass, I Love You." This song doesnt really have much bass above 40 hz and dips to 7 hz. It does very well in all the passages, but when it goes to the 7 hz part it obviously cannot play it at a decent SPL, but there was a little punch to it.
I did decide to watch The Matrix last night on it, and allthough it does not have the absolute best LFE, it did very well. The most memorable was when the helicopter hits the building after Neo saves Morphus. It slammed HARD, I felt like I got hit by the helicopter.
EDIT: So I just got done watching the bass classic War Of The Worlds Pod emerging scene in DTS and jeez did the SUB10 perform well. I never bothered to watch this movie in my old sound system because I knew my old Polk subs would get destroyed by this. So I did not really know what I was getting my self into, even though I heard that it will test your sub HARD. I was watching at around -25 Db on my Denon, with the sub a few Db hot. Lemme say that this scene scared the bajesus out of me when it hit. Mind you I am in a small 11 x 13 room, and this sub pressurized the room like a champ. Now its nothing that the high end subs can do but this is a 300 dollar sub, and it was shaking everything in the house. I was super impressed with the power this little sub has in it.
I decided to take the subwoofer out side to see what it can do at 1 meter. I wasn't expecting much but it did quite well. Its +/- 3 Db was at 25 hz (roughly), and from there it rolled off quite hard. 20 hz was at -15 Db, which I guess is not too bad, considering it is a sealed 10 inch subwoofer.
I can't recommend this subwoofer any more. For the price of 269 with free shipping is an awesome price.
