Elevating subwoofer about two feet off the floor

Actually, the question is whether raising the subwoofer off the floor about 2' will make it sound better. No need to purchase the bass trap that ASC is selling.

Hey, everyone, I asked this question last week because I could not do the test myself. My speakers were out for repair so the whole system was down. Today, the speakers were returned so I got to work. I raised one of my two SVS subs off the floor 11" inches by setting it on concrete cinder blocks with Herbie's footers under the sub. Personally, I think ASC is on to something. Raising works for me. The bass blended better with rest of the music.

I only posted their photo as an example. If you need a bass trap, then yes, their product would be helpful. But my room already has bass traps, so I just wanted to see what raising the sub would do.

hey ejr1953,

Thanks for the tip about Room EQ Wizard.

Okay, so I pulled the trigger and purchased an ASC sub-trap. Will report findings soon.

Okay, coming back full circle to the beginning of the question: is it useful to elevate the sub? I bought a full round ASC tube trap that measures 20" diameter and 30" high. I placed the trap just to the right side of the right channel KEF LS50 monitor speaker and set an SVS 2000 sub on top. I think the result was phenomenal. Tight tuneful bass that was in the middle of the sound stage. You can see the tube trap here:  http://www.ebay.com/itm/371567367597?_trksid=p2060353.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT
