Room simulator for multiple sub placement in REW 5.01 Beta 17

The REW sim look a lot like the hunecke.de simulation hunecke.de | Loudspeakers Calculator

However, it is a happily wellcomed add-on to REW!

Here are my simulation and measurements! A calibrated UMIK-1 and REW, 300ms. Same 10dB scale as in sim.
It took some time to adjust subs to get these mesurements, which sounded best. The worst room mode at 45Hz gets masked if I increase the volume from the subs even more. BTW if I use my HT am and 5.2 system, the measurement is even better. And teh second sub really helops, withoout I get a huge dip beween 60 and 100 Hz.

I measured at ear position which is the same as shown in simulation and in the middle of the room (mor)

Yes, I love the sound in my HT room! RT is good too! The subs are my PPSL470 (2x15") and a commercial 8" BR.

Some more data from Juhazi's HT room

Source - desktop PC running REW, usb to Audio-GD NFB-12, RCA to Vincent SV-129 integrated amplifier, speaker out to main speakers, pre-out to subs (R+L summed)

Input - mindsp UMIK-1 microhone usb to PC, calibration file

Room dimensions and speaker placement can be seen in the simulation and in this thread, post #24 http://www.diyaudio.com/forums/subwoofers/223960-bench-style-cabinet-subwoofer-2x15-closed-3.html

p.s. I hate my Pc's keyboard!
