Which Sub is better?

I was hoping someone could help with the situation I am having. I just ordered a Definitive Technology Supercube 2000 from an online store to replace my orb audio uber 10. I wanted something that sounded a bit better with music. The tiny definitive sub (smaller than the super 8) actually has better specs too. Before I get it though, I was wondering if I made a good choice. The specs for the Uber 10 are 10 inch driver, 300 watts (peak 500), and frequency response 24-160hz. It's also 13.5 inch cube (price 699). While the specs for the subercube are one 7.5 inch driver, two 7.5 inch low bass radiators, 650 watts, and a frequency response of 20-200hz (price 599 sale 475). It seems too good to be true. How could this thing be that much better on paper at a lower price and size even? Any thoughts on the comparison of these two? It seems like the specs would indicate that the super cube would not only be better for music, but it would also have a better low end too. By the way, the sub will be matched with orb audio mod 4 center channel and mod 2's for the other four channels. Here are the links for the two subs.

If I could get the same low end with the DT sub, but with tighter bass for music it would be worth the upgrade. It is also WAY smaller. Sometimes the orb sub sounds a little boomy for music and movies. I want tighter bass all around. Do you think they would be able to reach the same level on the low end? Does a bigger driver (10 inches) guarantee better low end? Where can I get the more technical info you were wondering about? Oh, the FR for the orb was found on a professional review. So, Orb 24-160 DT 20-200.

Sorry I could barely cut the 475 price of the DT sub. I am just looking for advice between these two models right now.

I guess I will have to let my ears do the test. Size is a big factor to me and that is why I was interested in the super cube to begin with. It is much smaller than the Orb Uber 10. I don't need a sub that goes lower than the orb, I was hoping that the super cube could at least match the low end, while giving me tighter bass for the music. Like I said, I also want something very small due to size constraints. I live in a condo and am already at the max as far as thumping bass goes with my neighbors.

Got the cube, so far it seems to be able to reach all the low notes of the orb. This is just from viewing common test scenes and music, so I will have to use it more to see. I also need to let it break in for awhile.

I ended up determining that the orb had better lows. However, wanting an 8inch subhas become a priority now. The wife is on my ass about something smaller. So, I ordered the super cube 4000. Do you guys think that this sub will perform better than the orb über 10? If not, what is the best 8inch sub out there? Please no huge sub recommendations.

Thanks, those look like great subwoofers, but they are all too big compared to the supercube 4000, which I got for 600 shipped. The reviews I found seem to be pretty good, and it is less than a cubic foot. Does any other company make something really good at that size?

Okay, so after sound testing myself and emails to company representatives for both Definitive Technology and Orb Audio, I decided I am going to keep the Uber 10 sub and return the super cube. It turns out the frequency range I was given by Will Christiansen from orb is 21hz to 164hz at +or- 3db he said that the 24hz rating on their website is with a +or- 1db variance. Although I liked the size to performance ratio of both DT subs, they didn't really seem to hold up after extensive testing. Now, although it is bigger than I like, I am probably going to keep the orb. Anyway, the only other sub that I may be interested in is the SVS SB12, but I was looking at that sub's frequency range at +or- 3db and it is 23-270hz. Would this sub even be better than the orbs 21-164? The SVS is also an enclosed design, while the orb is ported. Would that give an advantage for music? What do you think? Should I keep the orb or go with the SVS? By the way the DT Rep told me the super cube was rated at 26-100hz +or- 3db, not too impressive.

So no opinions on the orb vs svs knowing the specs on both now?

Will from orb said that the fr on the page (24-160hz) was measured at +- 1db. However, he said it is 21-164 at +- 3db. After listening to it after hearing the dt subs, I could say it does go much lower. The only reason I got the dt dubs in the first place is because I thought their advertised specs were real. I wanted to switch because of the small size, but now I see that a 10 inch sub is better. I don't think that the specs for orb are off. The dt guy said the super cube 4000 got down to 26hz at 3db (not the advertised 16hz), and the orb sounded much lower than that.
