Dual Sub Placement

[house72]

Hello All

I currently own a Single Submersive HP and planning to add a second one with in a month.

I have a quick question to all you folks about placement of my second sub.

My current placement is Left Speaker Center Speaker Sub Woofer Right Speaker.

I was thinking about doing Left Speaker SW1 Center Speaker SW2 Right Speaker.

Is this a good way to do? Ideally I would keep the second one near back wall, but my seating starts 2 feet from wall and this may not make it ideal for rear placement.

Any inputs appreciated.

Flanking the center along the front can give good results. I recommend making sure the placement is not equidistant from left and right side walls. Make one sub closer to the nearest side wall than the other sub by at least a foot. This will help minimize phase cancellation between the subs.

[house72]

Thank you so much for the feedback. In my case left side wall would be closer than the right.

Great question. I, too, have wondered about the ideal placement for dual subs (dual subs are awesome if you can swing it). I have had phase issues in my system to be sure, so I would say find a friend to do the switching and lifting while you sit in your favorite seat with a cold one (prob. have to promise said friend a few beers for his trouble). I'll bet you find a placement that just nails it for you. It's all about trial and error, at least that's been my MO with placement (unless you hire an expert).

I stack mine for a couple of reasons. I get a bit more overall output and I don't really have any other place to put it. As far as smoothing out the response, I have it EQ'd with a Behringer BFD.

I have mine as: Sub..L....C....R..Sub I had the subs flanking the centers but, there was an obvious movement from center(ish) to Left or Right of the lower end as the frequency changed.

I found placing them outside the mains has the effect of the sub and main being one on each side.

However, as DYohn said, cancellation is a problem. Mine ARE outdistance from the sides and thus, I have cancellation and reinforcement of the room's modes. Yes, I need to adjust. They do sound very good though on the outside of the mains.

Without knowing how you room is set up, any advise anyone can give at this point is pointless I'm afraid.

[house72]

Thanks for all feedback.

I am planning to play around, but for some reason feel like flanking will work better in my room.

Cheers

Mr. Symmetry here...

Out of necessity many moons ago, I had to set up my Subs with quite the same arrangement as Dyohn mentions. It works so well!!

I had to break my own rules of perfect symmetry, but...the result is waaaaaaaaaaaaay worth it!

Good Tip Dyohn!

actually front centre and back centre would be better.. if not able

then centre of each side walls..

if not front left back right right.. etc

sub crawl is the ideal way to find the best spots

cheers..

you ever heard of sub risers and the effect on the verticle axis?

cheers.

Luv this hobby!

We would need a quick layout of the room.

In the meantime take a look at this:

That was going to by my advice also. I have come back to this thread three times now thinking that I might have a better response if I thought about it, but each time I found I still agreed with your advice. What can I do but say "+++1".

[house72]

Sorry for not sharing room. I just gave quick shot of the room. Please let me know if I missed everything.

Let me know if this helps. Thanks again for all you folks help

Personally I would put the second sub under Surround 1 as a starting point.

[house72]

I will try that, but my worry was the seating being very close to the position.

Hey Cool,nice set up ya got.

This may sound strange but do you have room under the bar for it as an alternate location?
Does the bass rattle things now?

[house72]

I did experience once, with my wine glasses suspended close to each other. I redid the bar and the glasses have literally one glass gap between each other.

Rest of the bottles don't rattle. I have to rephrase the bar and call a wine cellar built in with solid doors. Its rear venting with latest cooling unit staying outside to avoid any noise coming in the room.
