15hz 100db SPL 4% THD

EQ can't help with room modes dude, If theres a dip, there will ALWAYS be a dip(unless you treat the room). It just levels off peaks.

Thats alot of cash It's safe to say the DD15 or 18 is out of my price range. Anybody else have any ideas? Thanks for all the help by the way.

What about the other 15foot wall? Can you put your TV on that one? Corner and long wall placements are not that great for a HT setup.

Correct me if I'm wrong, but I think the mob has spoken, 2 PB-12Plus's would rock.

The other 15' wall has a stairwell, door, and cabinets. It's basically a kitchen on that side. No chance of it working over there.

I was referring to the http://www.avtalk.co.uk/ subwoofer tests, which seem to indicate to me that the DD series requires room gain for decent SPL at lower frequencies. Whereas the SVS subwoofers do not. Regardless of the sub choice, as Sheep mentioned, your room will have a big impact on its performance.

yes, with the eq, you'll know when to move the sub. without it, you'd be scratching your head as to why it doesnt sound right.

although there were guys who upped a single frequency using 3 of the sliders

You can up some, but it can't be alot, or you might damage the subwoofer.


The Point is, In a 15 by 40 room the seats are going to be somewhere in the middle, and there is the least bass there. Having 2 will help with this problem.

sorry sheep, you cant damage a DD in that way. They have protection up to wazoo, you can place all sliders at one fq and still not increase thd or damage the sub(trust me I've tried).

And yes you can flatten dips even serious black holes(although this is not ideal, better to work with placement, which the on screen realtime sweep does best)

cheers

Easiest way to place two subs and avoid problems is to stack them. Not sure how easy it would be to do that with the subs in question though. I have my pair of subs right next to each other. I don't plan on experimenting with different placements until I get an SMS-1, as that would show me exactly what's going on.

15' wall has a door smack dab in the middle of the wall. Believe me I would if I could.

.....Stau40, your efforts toward a balance between audio and video for a Home Theater situation are jaw-whomped to start with, with the TV in the corner of a square or rectangular room....what does the door in the middle of the 15 foot concrete block wall of your basement give access to?......

.....edit....make that whomp-jawed....

 

[mike c]

sheep,
Bruce Hall himself said there will still be enough headroom even if 3 sliders are all put in one frequency.

The door on the 15' wall goes to a bedroom. There is an L couch that extends about 15' back from the wall. This is the main listening area. From the L couch back the room is mainly open, until you get to the back of the room. This subwoofer problem is driving me crazy.

.....don't go crazy yet, Stau, I've been there most of my life, and it should be avoided if at all possible, haha....ok, does the door to the bedroom open toward the bedroom, or toward the large room?....probably the bedroom....what I'm getting at is, the TV doesn't necessarily HAVE to be tight against the wall, allowing just enough room to gain access to the door to the bedroom....I feel most here would agree, that the TV centered on the 15 foot wall and not in a corner, is CRUTIAL toward what you are trying to accomplish....somehow, let's get the TV out of the corner and centered on the 15 foot wall, and then we'll worry about the sub or subs.....

Similar question about ideal SVS subwoofer for my room

You really need to be asking this question directly to the manufacturer. Go to the SVS site to contact them with your question. I'm sure they will be very helpful to you.

I wish that worked for me. I posted a question to them (SVS tech support) over a week ago and got nada in reply. I sent them a floorplan and everything. Luckily some people here seem to be more willing to help.

I have a very similar problem: I am trying to decide between SVS subwoofers, I know one of them will work out. My price range is $1000-$1500, I can stretch it a bit but I want to get a nicer finish. This will be used primarily for movies, but also music. I have very musical speakers (set of B&W CDM NT) and I like them that way. The subwoofer will probably be just to the right of the couch, or alternatively in the front of the room between the mains under the screen. We don’t tend to listen in very high volumes, in a much smaller room with a 7x100w receiver I would set volume at about -15 for movie watching. So I am trying to decide between:

1) A PB12 Plus in Rosewood (single driver)
Option 1 is attractive because it is the least expensive, the question is, can it give the impact for movies in that space.

2) A PB12 Plus/2 in Rosewood (two drivers)
This should give all the impact I need in that space, hopefully. Should sound and feel great.

3) A PB12 Ultra in Rosewood (single driver)
I am not clear what the benefit here would be, especially compared to the PB12/2 which seems like would have a much greater impact in the room, and has similar specs on paper.

The room is about 15x20' in the primary viewing area, by 10' high, completely open in the back to a 15x15' area that is 8' high. Total is over 4000 cu ft of space. All wood construction, mostly exterior grade walls (2x6 insulated).

Thanks for any opinions!

Hi Warped,

I apologize for the missed email. Chances are that your server, or ours, filtered it as spam. Did you use one of these email addresses?

techsupport@svsound.com
tomv@svsound.com

Either one will come directly to me.

Would you be able to forward it to me again?

Also, for anyone reading along, if you send an email to either of the above addresses and you don't get a reply within 24 hours...please try resending. We aren't perfect, but 99.9% of the time...your email never made it to us the first time. Thanks.

Now, getting to the actual question(s)..

With almost 5000 cu-ft of room space, the choice is easy...the PB12-Plus/2.

Set to 20hz mode, you'll get strong bass down to 16-18hz, with clean output in the 112-121dB range(depending on placement of the subwoofer---and how far it is from the key seating positions).

Please try sending me the room layout again when you have time...I might be able to narrow down those output estimates a bit more.

Sorry again about the missed email.

Tom V.

Well guys I'm taking your advice. I about to order 1 plus/2 for now with probably another to follow shortly. Wish they weren't on back order though. Thanks for all the advice.
