Dual Subs - What do you have & locations

post #1 of 94
Thread Starter 
I just recieved my 2nd PC-Ultra. Located on each side of my projection screen about a couple feet back of mains. Have not tweeked yet but I sense a fullness to the bass in the room already.

I have an SVS 20-39 pc-plus and a B&W ASW-650. The b&w is in the front right corner of my theater and the svs is on the left wall about 4.5 feet from the front corner.

I haven't taken any measurements yet but am very pleased with the sound. The B&W plays really loud down to around (I'm guessing) 30 hz and the SVS provides the tactile impact at the sub 30hz frequencies.

I think I would worry about the construction of my room with 2 ultras.

Cool, you got it! What do you have them tuned to?

Dual Velodyne DD-15s, at the 40% mark down each side wall.

2 pb10's and setup up the same way as you. I had them across from each other and it sounded like crap

Currently have 2 PB-12 Ultra's one in each front corner of my living room, soon to have 2 PCU's instead. Absolutely love it, and absolutely love hearing my wife complain because it frightens her!

A PB+12/2 and a sealed Tumult next to each other, right front corner EQ-ed by a BFD.

An SVS 20-39 PCi in the left corner and an SVS 20-39 PC+ in the right corner.

Dual PB10's running about half on the gains and staggered across from on another. One on the left of the HT and the other on the right next to the main seat.

Velo CHT12 behind the right main, and 2 Energy ESUB2's, 1 in each rear corner of the room, running full range. (small little guys don't go very low, but a nice extension for the LSi9 mains)

20 Hz native tune for now. I will experiment with 16Hz.

I have twin glossy black Plus/2s in each front corner.

Do I need two? No.

Do I want two? Oh yeah.

I read somewhere that the optimal locations for dual subs is on opposite corners of the room.

2 Mirage S10's next to each other up front.

Long time ago.....Replaced those things with 2 SVS PB12/2's. The 10's are thumping outside in the garage with the cars.

An SVS 16-46 PC+ in the right front corner; an "antique" M&K 15" passive in the rear left. (These are actually directly in front and back of my seating area, which is on a diagonal).

Experts would generally advise against this, but it works for me.

The arrangement flattens out my room response significantly. Not perfect, but measured +/- 4dB from 16Hz to 100Hz, meter compensated. (It sounds smoother, as the highest adjusted readings are below 25Hz, where ear sensitivity drops off. Measurement peaked at 18 Hz.)

No EQ on the SVS, but I use an ART 351 equalizer on the M&K, which is driven by a 200 watt AudioSource amp. I measured 108 dB SPL at my seating area on WotW, at -10 on the receiver. Room is 2200 cu. ft. including adjoining kitchen.

That will vary room by room.

2 servo 15's, stacked, placed 7 feet from listing position on left hand side facing backwards towards wall , not where they should be but the room sucks poo. Still sounds great though. In my old house the subs were on either side of the coutch and they sounded fantastic. In my new house they sounded sooooooooo bad it was crazy they basically cancelled them selves out, then I stacked them and bingo was thy name and his game was house crumbling bass!!!!! Ahhh the look on people faces when glasses shake off the coffee table is priceless!!

3 subs:
Two JBL S120's placed up front under my JBL S38s. They are set up to be the bottom to make the front L and R speakers be full range.
I have an ACI Titan II in the left rear of the room to handle the LFE sub duties.
The sound is smoother and cleaner and more effortless now with three 12 inch sub woofers in the room.
Of course (SHE) and the (BRATS) all think I am crazy.

Former: dual stacked Paradigm PW-2200 v.1's front right corner.

Current: 1 SVS PB12Ultra/2 left rear corner.

Absent 3 months, and noticed/cared.

Dual SVS PB12-Plus/2's symmetrically located in each front corner just behind the mains and at the bottom corners of the screen... tuned to 16hz in a fully sealed 1800 cubic foot HT room.

I have dual HSU VTF-3HO with Turbo. They're either in China or on a boat somewhere in the Pacific Ocean.

So far I'm not satisfied with the output. I can't hear them at all.
post #24 of 94
Two JBL B212 12" subs connected to the main L/R speakers; plus two JBL/Revel 15" subs, connected to the subout.
The 12" subs are right next to their L/R mates and the 15" subs are at the mid-points of the side walls.
post #25 of 94
Currently my subs are on the left and right of my screen just slightly behind the L+R mains. They are 2 double 18" Bag End boxes running in stereo via the ELF-1 processor. The bass is very even and capable of structural damage if I'm not careful. I am running them right down to 8Hz.

I have two recently purchased TN1220's placed opposite from each other along the side walls 80" from the screen wall and 62" from the first row of seating in my HT. I first tried placing them both in the corner to the left of my screen, but there was a big dip at my seating location, and the bass was lacking in some areas. So I moved one to the opposite corner, which helped the dip and the sound, but I felt the placement was still hurting the bass so I moved them just past the first columns on the side walls, and the bass noticably tighetened up and now sounds great. Now all I have to do is learn how to use RoomEQWizard and check my room to see if I need a BFD.

I have four SVS PB 12 Plus 2's arranged in a row symmetrically across the front of the room behind the screen.

Did you have to do anything to deal with phase issues between the subs?
And are they all driven from the same LFE channel?

I just bought an SVS myself and considering using it in conjunction with my other sub (Veloydne 18"). Not sure best way to set-it up.

Two PB Ultras stacked in each front corner. Not optimal, but midwall placement not possible in my room
