Sub Position In Big Room

post #1 of 5
Thread Starter 
We are buying a house that has a huge room in the basement that is finished. The room is 22' x 32' with 8' ceiling and I'm planning on building a fake 3' wal lin front. I have two subwoofers. One is a Klipsch RW-12 front firing and a Klipsch Sub10 down firing. Should I put both subs up front, or should I put one mid-way in the room?

you should sit on those subs in that big a room. tongue.gif

no seriously - depending on how loud you like your bass, a 10 and 12 inch sub are not likely to keep up with your expectations. if you can put them near field (close to your seating position) it will help them to stay pertinent in the room.

I feel your pain. Sitting in a 28x30x8 room myself and it is open to the stairway and the entire upper floor from there. Archaea speaks the truth. It hurts... but he is being honest.

I started with an Outlaw -EX approximately 8 feet from my couch in the 2nd best spot according to my sub crawl adventure. This is a beast of a sub compared to what I used before and it hurt to spend the money. I did it on the advise of members here (Archaea and others) and I'm glad I listened. $600 for a sub and it was JUST OK! The bass varied wildly just by moving 1 cushion over on the couch. BUT I fear anything smaller, like I had planned, would have just been lost in the room. MAYBE a PA-150 would have worked if I was willing to give on the lower end.

I've just added a RW-12D myself until I can save up for a 2nd EX and/or maybe a 2nd RW-12 also. At this point I have the 12D in the old spot (about 8' away) and the EX corner loaded after WAF approval (again about 8' away). So... ~$900 later and I at least have 'good' and somewhat smooth bass on my sectional. I would still like more... but for the time being at least I have some noticeable spl output and only about +-2dB from one end of the couch to the other. smile.gif

IF you can keep them close, and/or add another RW-12 or better, you might be ok. But don't expect window shaking or knick knacks falling. smile.gif

Buy a sub $90 USB microphone (like this one):

And get REW for free:

You will want to measure response from the listening position and try different placement options with the sub. Typically with dual subs you either want to place them mid wall on opposing side walls, or try one in the back of the room and one in the front. If you can do near-field placement, try that.

Good luck. I had dual 15" subs in my room which is slightly larger than yours, and I had to go DIY to get what I wanted.

For $1K I was able to build four 15" sealed subs and buy an amp with DSP/EQ to power all of them. Night and day difference in sound quality.

Yeah, and just so the OP is aware - that $1k in DIY is equal to about $2k in store bought sub(s). eek.gif

IMO, in that size of a room, you're not gonna get any sort of satisfying bass for less than $1k-$1.5k (store bought or ID). Personally, I wouldn't go with less than dual 15"s.
