Bass traps in a small HT set up?


I am presently using two SVS Sub Ultra 13 front firing subs in a small 10 x 12 room with really very satisfactory results. To eliminate any bass bloom or bloating, I am using a DS Peaker 8033. IMO, I think it does a reasonably good job. I am however, considering adding some bass traps in the corner of the room behind the subs. Does anybody know? Can I expect this kind of tweak, to give me even more improvement?
If so, what are the best kind of bass traps to use?
Remember, it's movies, movies all the way here!

You can expect dramatic results . For $700 of rigid owens corning 2 inch thick 2'x4' you can go floor to ceiling in all 4 corners. google superchunk bass traps. or you can by ready made ones for that price for just one trap that will cover one quarter of one corner .

My highest recommendation considering both acoustics and aesthetics would be Vicoustic Super Bass Extreme Bass Traps. I absolutely love mine - tremendous improvement.
Hello Bob,
Thank you for your reply.
Forgive my ignorance, but what are room modes?
I am using a Lexicon RX7 and a Yamaha CXA-5000 processor.
My front speakers are a set of Monitor Audio PL100's and GXC350 center. The PL100's sit on to of heavy granite stands on top of each SVS Sub Ultra 13, right and left of the TV & Sunoko Vent AV rack facing me.
I hope this helps. Do you need more info?
Many thanks,
Morgan.

Thanks Bob. I really do appreciate the time and effort you put aside with your very comprehensive reply. Awesome. Thank you so much! and most informative.
Now I understand "room modes" a lot better.

I am using the the Anti Mode 8033 in tandem with the Yamaha YPOA for the following reasons Mr. Kalman Rubinson from Stereophile magazine mentions in the end of his review of the Yamaha CXA-5000 and he says this;

"A look at the graphic presentation of YPAO's correction results revealed all (fig.1). All of the correction filters were of low Q (ie, broad in frequency), and there was little correction in the low end. One of the L/C/R channels now had a filter at 63.1Hz, but the rest were at 78.7Hz or above. No filters below 125Hz were applied to the L/R surround channels, even though their placements in the room's corners subject them to a severe diagonal room mode near 45Hz. Nor were any filters applied to the subwoofers below 125Hz; with the Yamaha's bass management applied at 40Hz (fronts) and 80Hz (surrounds), this meant that YPAO was not applying EQ below 100Hz.
Even knowing that, and despite its lack of effect on the lows, I continued to prefer YPAO-Natural to Through (no EQ at all), for the former's natural-sounding mids and highs. YPAO has filters that can have their center frequency set as low as 31.3Hz, and a more-than-adequate range of gain and Q, so it could be used for the bass¬óbut it seems that the correction algorithm made no use of these filters. This left me with three options: 1) I could use the RoomEQ Wizard, Omnimic, or XTZPro room-optimization software to measure and develop bass filters to add to YPAO's results; 2) I could add an external subwoofer equalizer; or 3) I could accept the Yamaha's settings and say that, although the Aventage CX-A5000 is an excellent, transparent, capable pre-pro, in this aspect it is flawed."

This is why I felt that the Anti-mode 8033 would go some way in solving the above shortcomings of the YPOA. It certainly seems effective..

There is only one more thing you mentioned Bob, that I do not fully understand, even after studying the Harman Kardon link. Why is it that you think that having my bookshelf speakers mounted on the subs is not ideal?
Is it that you think, (In layman's language) that the vibration from the subs might interfere with the sats?

Hi Joel,
I certainly did gets lots of good info.
I recently discovered that I had a few settings incorrect on my subs..
First of all- On my two front firing SVS Sub Ultra 13's, I discovered that before I ran the DS Peaker 8033 - I did not have the volume on the subs set to 2, like it said to do so in the instructions. There were a few other incorrect settings too and due to this the bass sounded bloated and not at all up to scratch. I spent about three hours carefully resetting everything one night last week. My conclusion is this - The DS PEAKER 8033 really works! Everything sounds so nice and tight now. I am really very happy with it all now. No need for bass traps and so on now, I am sure. The moral of the story is; when you get new gear, don't get too excited, take your time to set it all up. It will save you a great deal of disappointment in the end. Always take your time to read the instructions. Sometimes, isn't it great to state the obvious!
Cheers lads!
'Love That Bob.' How's that for dating myself?

Seriously, its people like this who take the time to write responses like this that make the internet great.
