Axiom Home Page Forums General Discussion Advice from Axiom Owners Do I have my speakers setup right?

bass waves are long enough that they don't get blocked by furniture in the same way the higher frequencies would. Also remember that it will be pretty hard to get good bass in every seat without multiple subs. This is a best effort sort of thing. You may eventually need to settle -- or throw lots of money at it.

Dear Mr. On-Topic,

I agree with Peter.

I would also think that - if the positioning of the seating DID actually make a difference, you would want to leave it configured in the way you usually have it for viewing.

I don't think you are going to be able to get uniform bass response at all the listening positions because some of them are so much closer to walls than others. I'd think you would have to do multiple sub crawls (as many as you can handle, I guess) - marking various sub positions and then moving the sub to the next listening location.

I'd be tempted to use a 20-80Hz sweep or something like that.

In addition to Peter's astute observation about throwing money at the problem, I just don't see any way to figure this out without you spending an extended amount of time on your knees.

I suppose I better go get some knee pads.

LOL!!

What a sense of humor!!!

So...I've watching this thread since it started... Have you done the crawl yet??

No I'm thinking tomorrow I may have some time. I have some buddies coming over to watch the NASCAR race in HD on my big screen and crank it up with the axioms. I still am trying to figure out where to put the sub, based on my above follow questions...

So have you done the crawl yet ? If so, what were your results ?

If truly is amazing. People with cheaper setups can have awesome sound. I love my current system. However, my friends system has more punchy base from the sub while mine exhibits more rumble. I like punch. So I am a little envious. It has a lot to do with placement and room acoustics. I have not spent the time to go over the placement of my mains and sub. It's all about compromise. And the optimal position for those speakers might not be physically feasible.

A ton of acoustics is the room. You can have a super high end sound system sound like utter crap if everything isn't setup right, or that certain room has bad accoustics.

I've moved my axioms around a bit from room to room, college and back, and couple places in my house. Definately a big difference.

Ok, I did the crawl recently. I will tell you, at first I kept moving around and thought I really don't hear a lot of difference no matter where I go? I tried variouos CD's with low bass. I even put in a cd mix I created that had nothing but BOSS Bass tracks. I even turned off the mains, just so I heard the sub only. Anyway, I think I did find a better home for the sub. Months ago, many of you recommended that I put the sub near the left corner, which would be the furthest cornere away from the opening into the larger room (see above pictures). Well, I ended up centering the sub below the screen, raised my center channel up onto the wall so it is more inline with my m60 tweeters. It actually looks pretty cool having my EP500 below the VP150, there is about 6" between the two.

Anyway, I think the bass is much better/tighter/explosive/less boomy...

I think I may rerun the RealTraps experiment again and post a new graph on my other RealTraps post. Bridgman is evaluating my results.
