Svs pb 2000pro not performing in small room

[hardcore_gamer99]

I just received this sub. My room is 11x11 only. I have denon x4800h sony oled Dali opticon 2 FLR and pansonic 4k player. I did subwoofer crawl 3 times. When i put it randomly between fronts it was complete NULL no bass in my sitting position. Then did crawl 2nd time deep bass was good but mid bass was zero. My settings are LFE and crossover to 80hz. In 1 place hollywood movie like spectre opening scene deep bass is good but same place my indian bluray does not give good bass there. Wtf is happening? I cant belive pb 2000pro not performing in small room it must give chest pounding bass
OVERALL I AM NOT HAPPY

The square dimensions aren't doing you any favors at all, they are notoriously tough to work with particularly with a single sub.

My office is a bit more forgiving, but similarly small in area. I went from a somewhat larger single sub to a pair of slightly more modest subs (still plenty enough for the small room) and got better results.

Maybe return the pb2000 for a pair of pb1000? Small rooms get a lot of cabin gain, so sealed subs with their shallower roll off are an option without sacrificing extension. So if space is limited, a pair of sb1000 is a viable alternative.

Probably not the feedback you wanted to hear. Sorry, man. But square rooms are not ideal.

A couple small sealed subs like the sb 1000/2000 would give you more placement options and benefit from room gain in that small space.

Would really need to see some measurements to see what's really going on.

The trouble is your square room. It gives reflections that are all time aligned and reflections all arrive at the same spots and in some areas will be antiphase and cancel and you get a null, in other areas will reinforce and you get a peak. You may well need four subs carefully spaced and times. 11 X 11 is just about a worse case scenario.

Probably best to simply keep saving up and buying more. Start with one, and try it in a position that's not exactly opposite the one you have.

I have a single subwoofer (JL Audio E-112) in a square 13' room, and in my main listening position it's perfect. Move to the chair next to the MLP, nearly nothing. I have every intention of getting more.

its too costly i just somwhow bought it. In india too much customs duty import fee etc... So youu mean to say single will never perform? Also can you tell should i do subwoofer crawl by putting sub on my chair . i had been putting on floor till now

The subwoofer crawl is always done by putting the subwoofer in place where your head would be, pointing straight ahead. Get a movie or music with deep bass playing, then YOU crawl around the room to find where it is that you hear the best bass output. That's where you put the subwoofer, pointing at the listening position.

It's possible a single sub will never get the kind of bass response that you want, due to the acoustics of low frequencies in smaller rooms. This is why Audioholics advocates so heavily for multi-subwoofer setups.

Even two subs can be iffy you don't have enough freedom in placing them in the room, as well as being limited by placement of your speakers and listening position. I got two subs and there is improvements but still a deep, fairly narrow, null around 31Hz.

so you mean put in onc hair where i sit or just put on floor where my chair is? issue is with sub crawl i here good bass but then when i place sub there bass is not great or same

Yes, put it on the chair where you sit, preferably right where your head is. Then go around the room, crawling on the floor where you might put the sub, and listen for where it sounds best. Then you just swap positions of you and the subwoofer.

1 thing i noticed when i did crawl 3rd time. while i was on floor bass was good but when i put the sub there that was not the same

 

[hardcore_gamer99]

Also should we not use any pads and put subwoofer on it? Is it must to be directly on floor

That shouldn't make a big difference.

bass is very deep while sub is in my chair but in actual bass is not that same. what could be issue?

here is the demo no time to die 4k on svs pb 2000 pro and dali opticon

Small, square-ish rooms are about the worst choice when you want good bass. Cancellation is your enemy. Bass traps are likely to be your friend.

Plz guide what is best material and where to install

What is your floor covering? If you have bass when the sub is raised, it sounds like you are getting floor bounce issues. I am far from certain that bass traps will help you. I think positioning will give the best results and suitable floor covering.
