Hey,

So I have been running an ed a7s-450 with the upgraded amp for a few years now. I love the sub but I am looking to save a little room (this is a 2+ foot black cube) and make things look a little nicer.

I'd guess I play 70% music and 30% ht duty with my system that is in the middle of an upgrade. I have focal aria 936 and cc900 on the way for the front and my denon 4308ci is going to be replaced by a mx151 and most likely an emotiva xpr-5.

 

I am looking for a "musical" sub or pair that would be fairly low profile compared to the ed but give me similar output. Can anyone make some suggestions for me? MY listening room is a large open space (about 1000 sqft) that is open to the kitchen and living room.

 

Thanks

Matthew

I was wondering if stacking a pair of sb 13 ultras would do it for me?

Stacking is a good idea, if your concern is output. Based on what you described, two subs will better serve your musical needs.

Sealed subs for small rooms.

Vented subs for large rooms.

It's an argument if one is better than the other for music with the nod going to sealed for music.

Two subs smooth out room modes.

Sealed usually has a smaller profile than ported.

With a budget for two SVS Ultras, which is an expensive, large vented subwoofer, consider a pair of sealed Rythmik F15HPs.

The OP mentioned SB13-ultra ... which is an expensive, sealed design and much smaller size.

D'oh! You're right. From Data-Bass, I have a picture of the ported sub, seared into my poor little brain like a tattoo.

The PB13-Ultra is indeed a monster wink.gif.

I have a preference for sealed subs dating back to my car audio days, not sure if this has just become a "habit" that carried over to my home system...

 

Are there other options in small footprint / high output sub that are less expensive than the svs?

This absurdly large ed sub (which I love) was half the price of what I am looking at...

Go to data-bass.com and you can compare your A7s-450 against the PB13 in sealed mode to get and Idea of performance. Looks like you will need a pair of SB13's to match the output. I think it would make for a nice setup and imo duals are better then a single anyday of the week. I say go for it. smile.gif

Btw The Rythmik F15HP or D15SE is a little cheaper, but it is not as compact...not sure how small you want to go?

Would stacking the subdivision negate any benefit to placing them in different locations.
I am pretty new an unknowledgable in the realm of dual subs in a home audio/theater system...

Stacking the subs would mostly negate the advantages that multiple subs can bring as far as smoothing out the room's response. It would simply double the output of a single sub's response.

+1.  Stacking subs will almost never be the better option, unless you have extremely flat in room response from one sub, or only have one placement option.  Spreading the subs optimally will give you, as mentioned, the smoothest frequency response along with the increased output/headroom of dual subs.  If you do not have the capability, you can measure in room for around $95 with REW and a Umik-1 mic from miniDSP.  This mic also serves as an SPL.  If your AVR does not have subwoofer eq capability, miniDSP can be added to your order along with the correct software, for a grand total of $210(REW, mic, miniDSP, software/plug-in).

 

This assumes you have a laptop computer and a long HDMI cable which makes setting up comfortable.
