Opinions on dual Subs
I have a Supercube II currently that I am happy with but have been entertaining the idea of SVS, Rythmik, SPA and HSU Subs. The problem is that my budget is between $500-$800 on a decent sub. I have a chance to pick up a matching Supercube II for around $250-300 in great condition. I have read that adding a 2nd sub makes a substantial difference and possibly the way to go over a single bigger sub. I’m not trying to spend over $1,000 on this sub because the wife would have my head. I have pieced my HT through ebay and craigslist over the last 10 years and have the patience to wait for a deal I can’t refuse. I was considering SVS PB-2000 dual Subs and I need to listen to the ported subs for myself to determine I want that feature over sealed. I love tight clean bass but need to see if I like the ported option. I’m probably 65% HT and 35% music. I had a chance to pick up a SVS SB-13 Ultra but $1,100 but was over my budget. I’m wondering if the extra $1,400 for SVS dual subs is really worth the investment over dual Supercube II’s? I just don’t want to drop that kind of money if it’s not like Standard Definition to High Definition type of transition. 720p to 1080p or even 1080p to 4k won’t justify it for me…lol

My Living room is about 18x18. 18x30 If i'm considering the open floor plan with the dining area and did not factor in the kitchen. My room is obviously not totally enclosed. I have a crazy idea of maybe converting my Garage into a dedicated HT room at some point where the budget would somehow magically expand.

I’m also wondering if eventually upgrading my bp10s to bp 30s would make a huge difference with movies and music? If I can find them close to me at some point that is. Im also pretty happy with the CLR 2000 and wondering if there was a major upgrade that would be worth considering for the center?

Can anyone also recommend the crossover settings for my potential dual subs? I’m still a newbie when it comes to home audio and depend on the calibration tool for setup. I am going to have a Sub in the rear left corner and the other sub on the front right of my room as the other options will not work for my room. Ive ordered a Y splitter since my amp does not have dual sub ports. Glad to be back on the Home theatre craze since I got my new home!

Do not be stuck on the idea that sealed somehow sounds so much 'tighter' than ported. A good ported sub will be able to match the sound quality of a good sealed sub.

As for the benefits of multiple sub systems, that is only true if you have some freedom to place the additional subs where it improves the frequency response. If you only have one or two places where the additional subs can be placed, you may not get any improvement at all aside from some more output. Do not expect to just add a second sub and then be blown away at how much better everything sounds. It takes some effort into calibrating the second's sub response to gain its benefits. Read through this article. And here is another one worth your time, and another one.

As for crossover setting for dual subs, just experiment with different settings when you get them, and keep which ever one sounds best to you.

As for brands, if I were you, I would sell the supercube. If you want to see the difference between sealed and ported, try one of the Hsu VTF subs or RBH I-12 subs, they support both sealed and ported configurations. Here is a roundup of subs you might consider. I would go for any of those well before the Deftech supercubes.

As for the upgrading towers from BP10s to BP30s, don't bother. If you want to upgrade, do so in a way where the difference would be immediately noticeable. No sense in spending a lot of money for a upgrade that is only subtle.

Imo, one excellent sub is worth more than 2 mediocre ones. Dual subs have the potential to provide more even response over multiple seats, and obviously more headroom. But that's not a guarantee, and if they're set up wrong, can actually make it worse. I recommend getting the best one you can afford, and then save up for a second(or break the bank and get two right away) Also, def tech subs aren't really that great, so I wouldn't buy a second one, and I'm pretty sure, using your analogy that an upgrade such as these would be like 480p to 1080p. I would look at these options for 800ish.

Any of these will provide you with tight clean bass, and destroy your supercube. Ported vs sealed in this level of subwoofers is non issue. IMO sealed only holds an advantage in size. And since you have a big space, you'd need multiple large high powered sealed units. Def tech is pretty generous(fudges) with their specs, which lists the BP10's as good down to 20hz, so I would start with the normal 80hz XO and experiment from there. Also going to the BP30's might be more a lateral move once you get real sub(s).
