Sub placement

Just looking for advise of where my subs should go. I have dual sv sb3000 subs, the first sub i will place in the left corner, the second sub is what I have a question on. Should I place it in the other corner or place it in the first arch facing the opposite wall in pics provided. Any advise would help. Or should I just place both on the front wall.

Try them and see. Placing and integrating multiple subs is not child's play. It involves patience and persistence, and often ancillary equipment to make the most of your sub investment.

First off, see if your receiver handles the subs separately, or does it tune as one unit? Corner placement may get you the loudest bass, but it often becomes boomy and muddy. Try it and see. I'm thinking center of room, on the front and back walls might be the best solution, but there is no way to know without trying it.

BTW, you have in-wall mains? That off-center speaker on top of the furniture is your center channel?

You need to do a sub crawl to determine where the sub(s) work best. Corners can often times be less than ideal, mostly due to corner loading has the sub reinforced by an extra barrier and will increase the output, but can make it sound "boomy" or muddy.

Subs>RBH I-12e, I-12. HSU VTF-15H mk2. Monolith THX 12(x2), THX 10(x2). XTZ 1X12. SVS PB-1000(x2). Speakers>JBL Studio 270/235c/230/225c. Sony CS3/CS8/CS5. QA 3020i/3090Ci, 2020i/2000c. Monolith Cinema 5bs. Polk RTiA1/CSiA4. Other Audio>Sony MDR-Z7m2,V6, XB900n,700,XB32,XB31. Sennheiser HD58X,HD4.50,PC37X. HiFiMAN HE4XX. Philips SHP9500. SIVGA SV004. SA HDTwo. HyperX CloudPS4. TB Elite AtlasAero. LG FH6,RK8,RK7,PK5. HK Onyx Studio4(x2).

My other dilemma is open floor plan with kitchen attached. The viewing area is about 3000 cubic feet with kitchen about 6000, these are not exact but I believe close. I sit about 10-12 ft away from front sound stage if any of that helps. Before I got second sub 1st was in left corner and other speakers are as viewed in pic. I did sub crawl for the one sub and left corner was 3rd best placement behind the 2 top spots in kitchen area, which is a no go. I just thought dual subs you cant do sub crawl.Attachment 2579972Click image for larger version

You definitely can - the 1st one goes in the best spot, and then you repeat, with both subs playing in mono. 2nd sub once again goes in the best spot, wherever that is.

The crawl isn't super reliable, though. Best if you use pink noise. Don't use music - you'll only be hearing certain frequencies, without knowing if you have cancellations at others.
