Possibly Build my next subs?

So if I have the time, I may look at building a pair of sealed 15" subs vs. say purchasing dual ULS-15's or waiting for the new SVS subs to come out. I currently have a PB13 Ultra, but it's just too large phyiscally for my room. I'd like to put dual sealed subs upfront. Considerations are:

1. I'm in Canada, so would prefer not to deal with US online companies and brokerage/duty issues if possible
2. Would want the boxes NO larger than say 18 to 20" (WxDxH)
3. Love to be able to get a gloss black or walnut finish (preferrably prefinished box)
4. Has to be relatively "simply" to do!

Room size is 13x17x9, not sealed (two doorway openings to Kitchen and Hallway). Front speakers are Paradigm S2 bookshelves which I'd probably place on the Subs.

May run them with an SVS ASEQ1.

Budget would be in the $2500 to $3000 max range for duals.

Thoughts?

Oh, would also prefer say a "curved" box, similar to the PB13, ULS-15 look versus the usual squared hard/sharp edged box.

With 2 subs, would one have to EQ the low end even in a smaller sealed box? Want to avoid as much THD as possible.

Have a PM into Dennis to understand the dimensions of that box better. How easy is it to find mesh subwoofer grills of different sizes btw? With a 2.5 year old, I need some protection for the woofers...

I may buy a prefinished box if I can find one I like, or have a carpenter friend of mine build a box to some spec. I don't think I'll have the time to personally put one together, buy the necessary wood working tools, etc.

Now I'm confused, isn't there a lot more to building a sub in terms of specing the right sized box/woofer, amp, EQ and other internals combination than just "install driver and turn on" into any box?

Yes, ideally no larger than 18 to 20" cubed, max. Can probably stretch this to 22" height (you can see in my linked pictures to my family room that the PB13 Ultra just gets above the Salamander stand, but I can likely increase the footings below the stand to adjust another 1/2" or so).

But 20" depth and preferrably 18 to 20" max on width.

How large is this puppy?

Interesting ... perfect size for me. Build Thread?

Okay, let's narrow this down a bit. I don't think I can do an external amp due to space issues on my family room rack. So I'm stuck with likely going with a 1000 watt Dayton amp (I think I may have a 750 watt Bash amp lying around somewhere as well, not sure how big a diff it would make)...

Assuming say a similar size enclosure as Fatawan uses above (might make it curved similar to the Paradigm Sub 15/25 enclosures unless someone thinks a 15" driver + PR can fit in this box and work better?):

1. What driver would work "best" in that enclosure and amp size
2. Will this sort of a setup compete in terms of clean output across say a 15 to 80hz range with my PB13 in 15hz mode?
3. Will there be enough output in the upper hz to blend well with my S2 bookshelves?
4. Would an AS-EQ1 be fine to use as a final EQ solution (seeing that the Bash amps each have a single PEQ)?

Or is the box size simply too small to best the PB13 even with duals?

Can also look at the eD 1300 watt amps if they would be that large of an upgrade over the 1000 Dayton above to justify the cost difference.

Go easy on me, entirely new to even thinking of building subs so some of the questions above may seem obviously "stupid", but not to me!

So I checked, and I "might" be able to fit one external amp if it could power both subs and do better than say the 1300 watt eD plate amp (do they make higher powered plate amps btw, can't seem to find any?). So not sure if a Crown 4000 would fit the bill, or an EP2500/4000 (though I understand there could be considerably fan noise with these)?

So still taking my time on this (if I do go this route won't be until likely mid to end of Feb), but want to ask as many questions as I can before I start.

The box may be smaller than I wanted (after measuring the space), and I'm looking at likely a box no wider than 18", say 22 to 23" deep, and 22" high max.

Question, if I were to go with say an LMS5400 15" woofer (i.e., find two used ones), but only have space for a possible single pro amp to drive both, would this severely limit the woofers potential? I have read that they "love" lots of power, especially in small sealed boxes. So wondering if 1 external amp would work better than say 2 plate amps like the eD 1300 for this application?

Just bumping re: any single pro amps that would be able to do justice to dual LMS5400 15" drivers in sealed enclosures of about 2.5 to 3.0 cuft? I.e., 1 amp, two small sealed subs?

Thanks guys. Another option I'm investigating is building a sub with the same dimensions/layout as the new Epik Empire (dual 15's), 22h x 18w x 24d.

I'd have the have the drivers facing towards the salamander triple 20 rack I'm using and the opposite driver would be facing the wall (say 2" from the wall) on the right side and out into the open hallway on the left.

Think I'll have issues with that sort of setup?

Leaning towards dual 15AV-H's (or AV-X's?), dual SDX-15's, or a much longer shot, dual LMS-Rs if I can get them, driven by one QSC 5050 or 1 Marathon 5050.
