Room Simulator!

[speakerman39]

Folks, been playing around with the REW Room Simulator today. Seems that I have gotten the hang of it now. Not real sure how accurate the results are. But, it appears that if I add a 3rd PSA S1500 it would NOT be a good idea to place the 3rd nearfield just to the left of my LP. I get the flattest response by placing all (3) S1500's up front. One in each corner and the third about half way directly behind my tv stand. Seems kind of a weird place, but it allows for the flattest response at my LP. Does that seem logical? Or should I take the Simulator with a grain of salt? Any thoughts?

If I place a 3rd S1500 behind my tv stand, then that will shorten the distance to the LP. Any benefits in doing that? Right now my LP is about 9.5' from my front-stage. As such, my LP will be about 20" shorter or ~ 7' 10". Not too sure how that would work. Was hoping to place the 3rd S1500 more nearfield. Any suggestions? Comments?

Cheers,

Phil

Okay been playing around with the X-over and it appears that 70 -75 Hz is the best point for the flattest response at my LP. Usually prefer to X-over my subs at 90 Hz. Sometimes 80 Hz works well too. Not too sure about 70 Hz though. Just find the Room Simulator very interesting to say the least. Once again, does 70-75 Hz sound logical? Any and all help will be most appreciated.

Cheers,

Noticed that I get the flattest response at my LP when using (2) S1500's. Adding a third does not flatten things out much. I have a peak at 46.7 Hz and a slight dip at 65-66 Hz. Of course, that is using a 70 Hz X-over. Not too sure getting a 3rd S1500 will be worthwhile in my room. That is, the simulator is making that very obvious. Not sure how accurate it is though.

Cheers,

You're probably going to need to step up to the Seven Sub Solution for that apartment.

According to the Room Simulator, adding a 4th S1500 really complicates things a bit. The third S1500 does flatten the response a bit, but nothing day or night. My room just does NOT like me placing a S1500 to the left of my LP. As such, placing nearfield is NOT going to work. Will work on it some more and see what I come up with. Hopefully, the Room Simulator is pretty accurate.

That will be pretty easy to check once you stop playing with Rm Sym and plug your mic in.

Remember- you can place the speakers and subs in 3 dimensions, so height is another variable that can be changed- speakers and listener's head can be moved.

Was NOT aware of that. Will be sure to look at things from that angle. Thanks for the info!

Look in the lower left corner- that's where you adjust height.

The creator of REW is a contributor at another forum- it doesn't do odd shapes and there's no provision for center and surround speakers, but that may come later.

Yeah, I see where to check it out. Thanks for the info. Not sure how to fully integrate it, but will play around with it some more. BTW, do you think that the Room Simulator is accurate? Hope I am not wasting my time here.

I don't think he would have added it if it wasn't going to be useful but, as I wrote before, it's for rectangular rooms. Unfortunately for me, I have a theater to do in a room that's basically shaped like a T and now, they want to turn the whole thing 90 degrees, which means one side is a wall and the other opens into an area where they want to put a pool table.

I see. Sounds like you got quite a chore to do. Plan to mess with the Room Simulator to see what I come up with. Thanks for the help. it is most appreciated.
