Last month when I ordered my Monolith 12” all of my subs favorite place was a front corner beside my TV stand, no matter if it was my BIC PL-200 II, Polk PSW505, Monolith 10”, or Monolith 12” they all loved that front corner.
My buddy has a SVS PB-2000, I took him my Monolith 12” & took his PB2K in the meantime and threw it in that front corner...nothing. Absolutely nothing. I called him and made sure he didn’t make me haul this 80lb 12” around for no reason but a giggle but he assured me it shook his room. Remember my room is 9x15 so it should be breaking drywall. It didn’t matter if I had the gain maxed out & the AVR trim at +5 w/ a master volume of 0 it wasn’t doing ****!
I ended up throwing that beast all around my room, different corners, halfway on side walls, middle of the room, anywhere there was open floor space. I pm’d mthomas as well, made a thread, etc. I received the same suggestions you have, something is not right.
After two days I totally rearranged my room, flipped the furniture, moved my seating, throw my TV & setup on the other side of the room & wallah; output!
Between my placement & seating I was in a massive null bringing the output down 27dB...27dB!
My point being, every sub I’ve owned loved that one corner until the SVS PB2K didn’t, it created a bass black hole, sucking all output down the abyss. This sounds exactly what you are experiencing. It sounds like you spent more time packing & unpacking than you did trying to integrate the PB13’s. Just because your HSU’s like that front wall doesn’t mean every sub is going to. Also you didn’t even adjust the gain according to your post so I’m curious if you wanted the PB13’s to work in the first place...
You can buy every brand of subwoofer available in the world but, if you don’t find the correct placement, make sure polarity is correct, make sure there’s not phase issues, address nulls & modes, & take the time to properly adjust your system settings, you’re just wasting money whether it be shipping or purchasing them, wasting your time, etc.
It would have been much simpler & easier to find a remedy to your placement issues than packaging both of those big subwoofers. I’m not trying to upset you or sound cynical but, there’s no point in experimenting with other subs if you aren’t willing to accommodate their best placement/settings needs
. Yes it is a need. If you expect tremendous output & extension, you’ll have to experiment with different gain settings, different PEQ settings, different phase settings, different phase settings, different AVR settings, & most importantly different placement.
It seems between your front wall & your seating you are experiencing nulls &/or standing waves. Even moving your seating forward or backwards 6”-1’ can fix these issues.
I’d recommend getting these running right, stop worrying about aesthetics so much for now, then once you figure out what the best setup is, go from there.
Anyway I’d be willing to help if you’d want to unpack them but, I don’t see buying a different brand would remedy your room issues.
