Im fairly new to HT, and I am currently trying to start my second subwoofer build, as my first one is just not going to cut it.
My current equipment:
Receiver - Pioneer SC-67
Sub amp - Crown XLS 2000
Current sub - My first DIY 10" JLW7 in 4.1cf ported box tuned to 20hz (Should be able to see it in the pictures below. Please ignore the Dual W3's. My brothers car subs.)
The issue I am having is that I got a small taste of low end and I want more . The room is large and I just don't think a single 10" will cut it.
24' x 17.5' with 14' vaulted ceiling. And then off course it opens up into an almost identically sized kitchen and then a hallway. I understand this is less than ideal but its what I have to work with...
Please excuse my mess in the photos. We recently had our first daughter, and I just finished rebuilding the entertainment center below the TV.
So, im limited to a budget of roughly $1000, so utilizing my current amp would be ideal.
I am being "allowed" either two "Large" subs or four "Small" subs. This is how my wife refers to ported and sealed boxes. Either two ported 15"s with a max 6cuft each, or four 3cuft sealed. (I made mock up cardboard boxes of what roughly each size was to be for the wife, and those are my allowable options).
Goals: 70% HT and 30% music.
Basically I hooked up my W7 in one of my spare 10' x 10' bedrooms to play call of duty on my brothers TV and I heard and felt sounds I didn't know existed in the game. 4 hours later we finished watching "Medal of Honor" and now I want "that bass sound" in my living room. Best way I can describe it, sorry.
I had planned on using the 15" Dayton Audio Ultimax subs because of the perfect "recommended" enclosure size and price. Please, any advise on using these subs, going the ported or sealed rout, and any other advise would be much appreciated.

Psychotic Episode Averted
Here is a model of a few drivers. I don't know how much power your amp can put out exactly so I just went off the manufacturer specs.
Yellow is four 15" Ultimax in a 3cu ft sealed enclosure each (12cu ft total) with 2100w.
Blue is two Dayton 18" HO in a 4cu ft sealed enclosure each (8cu ft total) with 1300w.
Gray is what you currently have, 4cu ft tuned to 20hz and 500w.

If you really wanted to go ported then yes, you would need a high pass. I think given your size constraint the quad sealed ultimax 15s is your best bet. You could do a pair of 6 ft3 dual opposed cabs, or four 3 ft3 single cabs.
Thank u for your reply Jay. Im open to either ported or sealed, however I think your right. Size and price would make sense to go sealed seeing I would have to buy additional equipment.
Now I don't have any experience with dual opposed. Is there any +/- going 2 dual opposed vs. 4 individual box's? I will do some forum searching to get up to speed for that style in the mean time.
Another concern would be room response. im new to this but there is defiantly a "boomy" part of the room in one corner. Would having 4 box's instead of 2 dual opposed be better or worse for this issue?
They can be stood up or laid down if it fits better in the room. The enclosure is a lot bigger than you're looking for but the price and sound are both right from them. 2 in one room should be all the bass you're looking for.
There is also a similar design floating around out there - the THT - that gives pretty much the same output but is in a different form factor that may or may not work as well in your room but is something to consider for another option.
