Go to this forum. One of the guys gas a link in his signature called 'Getting started with REW a step by step guide'. I thought that guide was awesome.

Doesn't look like it changes your FR much at all. You probably need to move one of the subs to a location where it will help the FR.

I have moved the V1500 around quite a bit in the limited area it could be moved to. This was the best I could do. Wondering if adding more bass traps would help instead of adding a second V1500.

^^ just want to be sure that you rerun AVR auto calibration after each sub move. There should be a difference/improvement with dual subs. Your graph does not show.

Have you tried opposite corners of the room? Or do you have them both up front?

I did not. I ran it after the fact I guess now that you mention it. The single v1500 measurement was taken after auto recalibration. I will try to get another measurement this week and see what it looks like i just ran out of time today.

I could but would need to get a wireless transmitter, then if you go wireless with one you should go wireless with 2 right?

I was doing the 1/4 option here. Physically that is my best option with cables.

You could probably do one wireless and not the other and it would work just fine. I do, however, think that you shouldn't really have to move around much more than you already have. As you graph suggests, you are doing pretty good with one sub. What I would do (when you have time again) is put both subs how you "want" to have them... in other words, put them in the 1/4 option. Then re-run MCACC fully. I even would go so far as going through each step in the Manual MCACC option and going through it one by one.

I put my subs in their "spots" as I don't have any other options. I connected the miniDSP and bypassed every filter there it had. I then ran MCACC in expert mode with the "all channel adjust" selected. Afterward, I grabbed the SPL meter and sat in my MLP and manually adjusted all the channels (which really was only minor adjustments) to 75db. Some channels were just a hair bit over 75 while others were slightly less. I did the gain correction. I took the loudest sub and used it at my default and raised the less loud sub a tad to match. I then bumped up the subs to be a bit hot (-5db to 0db). Afterward I went into MCACC manual and ran the full on equalizer again. Then reverb.

Needless to say they sound amazing. I watched The Avengers with my family today and I was so impressed. Now... I have a huge room with tile floors. It should be very difficult for me to be impressed... but I am. I think you should try and it get it looking "sounding" good without REW and then once it sounds good without REW then use REW to get it that much better. I don't think REW is going to make something that is really lacking all of a sudden satisfying.

A few side notes... I have the room size knobs maxed out to large. I also set my XO to 100Hz for a little more headroom (MCACC set all my speakers to +4-6db).

Big nebbish question here

Can undo sub crawl and best location with no furniture in the room? I've never NOT had furniture in the room so that why I ask. Obviously a lot easier to move things around without furniture.

Also would like to run ReW to see where the flattest locations are for the duals

I would think that heavy furniture would have some impact on bass, sort of like bass traps, but I think you would still be able to get a pretty good setup regardless. I would guess that any effect it would have would be more in the upper bass region anyway, probably above crossover.

Thanks jhughy2010. I will try your approach. The dabate for me is really is the cost to benefit ratio of replacing the old SVS with another v1500. To clarify what i am getting at is if I go dual I want dual v1500's. I was hoping there would be a night and day difference in REW to help justify. Either way I wont keep the SVS hooked up for long. I will recalibrate MCACC and try again this week.

Got the house to myself today so I moved my sub next to my front left speaker instead of the front right speaker. This puts the sub closer to my rooms only corner. I also ran Audyssey with the room size set all the way to large. Immediately noticed an increase in output. Without changing the gain on the sub, Audyssey set the sub level to -5 from -3 when it was in the other spot. Going to play a few scenes before watching the new Hobbit.

Brian I agree with Bear. After reading a lot of posts from Bill F It seems the real player in sub FR are the room boundaries. Of course bass traps change things because of absorbing the waves etc.. I admit I'm guessing here but it would seem to me that your seating would act minimally as bass traps and therefore they might change things slightly but with all your walls in place you really have what you need to do the sub crawl. Just guessing though.

I believe Bill F. mentioned that for bass traps to have much effect on frequencies below 80hz, all the walls would need to be covered 6" thick with acoustic panel/foam.

I have read more than once that due to the delay created by the wireless transmitter if you do it for one sub you will need to do it for all subs others wise your calibration software can't set things properly. I can't verify that because I have no first hand experience with it but that's what I've seen posted in other threads. Some guys here have it though, maybe they will chime in.

I believe you are right about that. IIRC I've seen Bill say that the long bass waves require seriously thick traps.

+1. After much moving of subwoofers I found the best response in my room was opposite corners…By far the best.

Gotcha. I have 6 inch thick 8 foot tall traps in the front corners right next to the screen. I have a recessed screen area that those are in. I could also add a couple 4 foot versions of those traps outside of that recessed area and also do the same in the back of the room. But that's not covering the entire wall with stuff.

I'll give it some thought. I just hate to buy a couple sets of the wireless transmitters just to see if something might work.

Just watched the Pod Emergence scene from WOTW. I could see the driver moving like crazy but couldn't feel the deep bass. I just don't think my room is very bass friendly! Can't wait to add a second V1500. Probably need at least four in my room lol!

FYI - you should optimize the placement of both subs (using REW) with Audyssey OFF. After you have the best response you can get, then you run Audyssey.

Don't let a few bucks for some longer cables compromise your sub's position.

Get some longer cables and put a sub in the back (or both) and take some measurements...you'll know if the wireless transmitters will be worth it after that.

I haven't yet received my mic so have been unable to run REW. But using the ear listening test the best position for dual V1500s is 1/4 from the front corners. In the corners I have GIK soffit bass traps.-huge boxes and GIK wall panels throughout the HT which affect things.

I tried mid side wall and it just didn't have the impact I was looking for. I haven't tried opposite corners. Kinda of a pain to do that. I'll know more once I run REW.
