Boomy bass - please help

[plasmoid]

Hi all,
I had recently shifted to a new apartment and set up my stereo. I seem to be getting boomy bass in the new living room. Tried shifting my setup in different positions, moving speakers away form walls, using doormats under the speakers, plugging ports etc. but all is in vain. The open doorway leads to a dining room with french windows(no curtains). I was wondering if this was the problem.

The same setup sounded real good in my old place even though the room was a bit smaller. The new apartment is rented so I can't really make any sort of structural changes.

Can you please suggest some other alternatives (apart from moving to a different place :sad

Have attached a rough floor plan of the room

Thanks...

Do you have enough furniture around? Are you sure it is boomy bass and not reverberation?

I have 2 wooden chairs with foam cushions(same as the old house)...yep the bass is like a deep boommmm. Also my speakers are front ported. The ceiling has a thick beading...was wonder if this was causing it.

What is the room size? Is it a square room? Square room can cause this. Put some pillow at the floor corners behind the speakers and see if that reduces the boom a bit.

Two wooden chair is not adequate. You must bring in some more furniture or treat the room acoustically.

Room is rectangular, roughly 13x9 feet. Tried pillows...reduced a bit but hardly enough. You have an idea if these would work:

What kind of carpet is better - coir (seen these in demo rooms) or the regular Persian ones.

Ofcourse these helps. The price seems still on the higher side though. Best if you can build them using glasswool. Much cheaper but equally good solution.

I have seen this discussion about whether a carpet helps low frequency boom in other forums as well. Many people think that due to the size of the standing wave created it is "transparent" to the surface below? I leave my doors open to reduce the boom somewhat, which was a good suggestion by a fellow FM. You really need the right room treatments - which are very invasive I feel - or a super room correction system.

how to make these bass traps living room worthy?

I mean can you make them fit the decor of a living room?

Different room configurations have different acoustic characteristics. Keep the speakers at least 1 foot away from the side walls and back walls. Also, when you place you speakers on the floor, the floor acts as an extension of the lower part of the baffle. You can place your speakers on stands, which are about 0.5 foot high. Increasing the height from the floor will reduce the boom. When I moved to my new house, I had the same problem. Reduced it by using speaker stands. Also the boom and room-echo will reduce as you fill up your room with furniture.

My Speakers are floorstanders so no stands :sad:

I find the write up below the product (for the link you have provided) to be very useful. It clearly says that the corner trap depth needs to be selected in relation to the frequencies that are causing a boom in you room. If you select one that is not approximately appropriate at least then you may end up spending a lot of money with little benefit.
It could be worth contacting a local acoustician in your area and getting him to "map" your room so that you can get the most out of your acoustic treatments.

Thanks for your help...in the meantime I was wondering if a carpet would help - coir or the the regular Persian style would be better...have seen demo rooms with coir carpets...also would one be enough or 2 stacked?

I use a short pile carpet in front of the speakers. It definitely helps with taming floor reflections. I am fairly sure it would be of very little use when it comes to taming low-frequency bass boom though.

You're having lots of Reverbs, echos due to empty space. You don't need to do much, just do the following:
1. Add carpet (nylon, woolen) desi carpets do just fine
2. Add curtains (heavier the better)
3. Add furniture (optional)
4. Move woofer to center, 2 feets from wall.
