I was thinking that you would place your SPL meter at your sweet spot and take measurements that way. You would keep the position constant and just vary the frequency.

If you get really bored, you can vary the position also \:\) . I am mainly interested in how much difference it made right at your sweet spot.

Good work, Sean. Yes, on the question of boominess and positioning it isn't necessarily being too close to the walls, but rather that the center of the woofer cone shouldn't be an equal distance from the side wall, front wall and floor, if possible.

Is this boominess from your speakers or the sub? I know my sub gets quite the boost to become boomy when in the corner like yours. Maybe try moving the sub around or better yet do the dreaded sub crawl, when you are off to try to find a better position for it.

Jason, the boominess comes from the speakers. Really noticeable with two-channel listening, during which I don't run the sub. I like the boom during movies! (insert sheepish grin)


And, JohnK, my speakers play pretty low (less than 30Hz) and I erroneously thought that putting them too close to the wall would accentuate that. Sometimes, it's okay to be wrong!

Hi St.Pat guy,

Like others here, I like your stand and I also was curious about that big spider. Looks a bit like the big dock spiders I used to get on my floating dock up in Georgian Bay (Lake Huron).

What are your main speakers, by the way? Big enclosures, so it doesn't surprise me that you might have issues with boominess depending on placement. And yes, it is amazing what audible changes are invoked by slight readjusments in speaker location. Sometimes when it comes to low bass, I throw up my hands and say, "The room is EVERYTHING!"

Regards,

LOL @ MSJ! \:D \:D

Sean, those pictures are great. +1 on the ingenious center channel accommodation.

I used the Room EQ Wizard (REW) software available at Home Theater Shack. It makes uber groovy graphs if you have the right sound card and an SPL meter. You can also use it in conjunction with a Behringer FD unit, but I think it would work stand-alone just for analysis. Very quick and elegant once you get it going.

I'm going to have to try that software out once I'm able.

Thanks, Alan. Not a dock spider, just your typical black widow. Don't usually find these gals inside.

Odyssey Audio Loreleis. From the same guy that Sirquack and Haoleb got their amps from.

Regards,


And heavy, too! The room I had these in previously was smaller, but I didn't have that much bass issues. In that room, which was square, I ran them diagonally trying to avoid bad reflections. Yes, the room can make or break things. It's amazing how bad a good speaker can sound if not set up properly.

Thanks, Tom! After I moved and rearranged my system, I was determined to make things work with what I had. I didn't want to spend money on a new stand. Such a simple solution, but it took me a week to think of it! \:D Hey, I never said I was smart.

I am frustrated with software because nothing seems to be available for Macs. Maybe there is now, but I gave up looking a long time ago.
