sub crawl questions

[NINaudio]

So I previously did the sub crawl when I had a super cube 4000. I'd really like to make sure I'm getting the most even response possible with the ultimax at my MLP, but I had a few questions though:

I'm wondering if it is something that needs to be redone for a new sub with lower extension?

If not, would I be able to place a smaller sub at the MLP and then measure for where that has the best response?

I still have the SC4000 and it would be much easier to place that in a different position and test for the best response than moving the beast to the couch, plus I wouldn't require help for moving the SC4000.

If I understand your question...you have new sub that is difficult to move around and want to use a smaller sub to find the sweet spot and move the larger sub to that spot.

It might not yield the same results, but it certainly won't hurt.

I did the crawl test, and lugged the subs around. Then I ran Audyssey and they ended up being best along the TV wall...same as the crawl test would have them. I will admit...it's much much easier to balance out the low end frequencies with 2 subs of the same elk.

Admittedly...you can probably find a happy medium for the MLP with one sub, but if there's more than one seat...everyone being in the bass sweet spot is challenging with one sub..

Do you have a measurement microphone? It's much easier and better than using the subwoofer crawl.

I have a umik and a laptop loaded with REW.

I would just use that to see what the response is. Measure the response at the places where the sub can go. Use the best spot. Remember that its better to use a spot that has more peaks than nulls. Peaks can be EQ'd, but it's not a good idea to EQ nulls.

Same idea though, put the sub in the MLP and then run the sweeps through REW?

That is correct. Hard to pickup a 100 lb sub and put it up on the couch by myself! Unless there is someone in northern NJ that wants to help.
