What size sub or subs for a 21' x 14' home theater

post #1 of 20
Thread Starter 

I am in the process of setting up my first dedicated home theater and am looking at upgrading my sub (currently a Cerwin Vega ARPH 02300).  My other components are an Onkyo TX NR708 receiver, Artison Portrait LCR (older model that I just bought used), and Artison Portrait LRS (bought new old stock). I am still up in the air about adding two more speakers to make it 7.1 so I have not purchased anything for that channel.  My walls and ceiling are drywall and I have porcelain tile over a concrete slab.  I have three doors and one window in the room.  I keep the doors closed during movies.  I can try to sketch something if necessary to show the layout.  Based on the above what size sub or subs should I be looking at?  If there is some additional information needed please let me know and I can try to provide that as well.

Budget? Open to DIY? Goals? WAF or size limitations?

I have not completely decided on a budget yet. I am hoping to get a few different options and then weigh out the pros and cons, cost, etc.  That being said I would hope to stay under $1000.00 if possible.  I am open to DIY as I have done most everything myself up to this point ( the room remodel, ran the cables and wiring and built my risers). Goals are to have a good sounding home theater to watch movies in. I am not sure what "WAF" is and I am not sure on the size limitations. I guess that is where a good sketch or picture of the room would come in handy.

For under $1K, options include:
- PSA XV15 ($799, shipped); and
- dual SVS PB-1000s ($949, shipped).

The new SVS PB-2000 ($799, shipped) might also be an option.

For just over $1K:
- HSU VTF-15H ($879 + $143 shipping)

Is there any correlation to the size and make up of a room vs. the size of sub one should run?  From the suggestions I see several different sized subs.

How do the offering from Definitive Technology SuperCube's rank with those suggested?

If you're willing to go DIY I would strongly suggest that. Pick up two SI 18's http://stereointegrity.com/index.php?id=57# and buy a inuke 6000DSP http://www.parts-express.com/behringer-nu6000dsp-inuke-6000w-lightweight-power-amplifier-with-dsp--248-6710

Build two 4cubic/ft cabinets for them and away you go.

For a $1000 a HSU VTF15 will be about the most amount of sub you'll be able to afford. Go to data-bass.com http://www.data-bass.com/data?page=system&id=90&mset=97 And compare the graphs of a single SI 18 to the VTF15, a single SI 18 is very comparable to a VTF15. Adding a second one only improves things.

Of course my recommendation is all based around you willing to go DIY.

Where are the laughing till you cry emoticons? If I could use them I'd place about 1000 of them in response.

In other words- they are not even on the same planet.

Rythmik has some excellent choices for around $1k.

Dual SVS PB-1000 subs would be my pick at $948 shipped, but HSU and Rythmik would be excellent choices too if you only have enough space for one sub. Forget the SuperCubes.

A room that size is going to call for more than one sub for good coverage.

Thanks for the input. So is the general consensus that I should go with (2) subs?

It makes all the difference. You need at least two subs to get reasonably smooth response. With that 21 foot dimension you won't have appreciable cabin gain, so you want ported subs that measure well to 20-25Hz (see data-bass.com for measurements). For low level listening, ie., what your wife will consider plenty, two tens will do. For more realistic levels two twelves, for better than theater levels two fifteens, and for IMAX two eighteens.

if there's a recipe how not to build an HT that would be it. Having all hard surfaces pretty much guarantees a bad listening experience. Required reading:

Thanks for the info. That is what I was looking for.

 

As far as my room being "...a recipe how not to build an HT...", it is what it is. I am simply working with the finishes I have throughout the rest of the house.. In a couple of years when I sell, I am sure I will get more money as a 5th bedroom than a media or home theater room, so I am going to keep it such that all I have to do is remove my "stuff" and it can be utilized in that manner.

There's a lot of good advice in this thread from some guys who are really worth listening to. Eljay broke down some nice options for you and rnatali also gave some really good choices as well. Bill and Prime explained how two subs would be better than one, especially in a room of your size, and brown has even opened up the option of DIY. But now you have the hard part, you have to decide which option to choose. My advice is to have fun with it all, not many things are more fun than getting new subwoofers. :D

Yep My room is 16x30x8.5 and I have these now but am upgrading to dual PB2000's that just came out.

Having said that the dual PB1000's in my room that is much larger did a really great job!!

Reason I am upgrading? SVS's great Bill of rights , one of them is a full 100% credit if you upgrade within
1 Year. Also they have a 45 day trial period, if you dont like them you send them back full refund, no shipping
costs either , either way.

Right now the Best customer service in the industry.

Return customers also get 5% discount, even on the upgrade.

Call them tomorrow and order them.

I didn't know SVS offered those deals. Not sure if that would be good, full credit if trading up in a years time. I'd have a new sub every year! eek.gif

If within 45 days then there is no shipping cost either way, outside of the trail period buyer is responsible for shipping both ways, IMO this makes the upgrade for dual subwoofers costly, almost $400+the cost of the new subs if you are upgarding from PB12NSD to SB2ks

The SVS Sound website has a wizard function they call Merlin that will help you figure out which of the SVS subwoofers would be a good match for your particular speakers - presumably matched in timber?  Just enter the brand and model information for the speakers you plan to use and voila a list of suggested subs pops up and they even provide the setup settings (on the selected sub) for blending your speakers to the sub you buy.  Anyway I found it helpful since I have decided to buy an SVS sub.  If interested you might go to svsound.com/Merlin

 

Make sure to check out their Outlet Specials for discounted pricing on slightly used equipment - they offer free shipping both ways, a 45-day trial period and a full 5 year warranty on the used items which I think is impressive service.
