    New Member Introductions
    Hello everyone! Just stumbled upon the REW software and was looking for resources. Got a studio PA that's quite loud but needs serious EQ help. Got tired of tuning by ear. Using an RS 33-2055 SPL and a laptop for measurements. Sound card lets me set line level and the calibration was...
  2. Target curve filter fine tuning advice

    Home Audio Acoustics
    Hello everyone. I've been getting the hang of REW and would like to get some critiques regarding my before and after EQ curves. My concern is the very narrow (0.200 BW OCT) 9db gain at 55hz to treat that null. Is that okay? I also have a very narrow and deep null at 270 hz, could this be an...

  6. HT Subs: Sub-30Hz tuning really necessary?

    DIY Subwoofers - General Discussion
    Hey guys, I have been having a look over quite a few specs for commercial cinema subs. And the one thing I have noticed is that a lot of commercial subs extend down to about 30Hz before they roll off. THX certified subs seem to extend to 22Hz or so before the roll-off. So that sparked my...

    Hello all, I got an idea that might get me lower tuining with this subwoofer as I am not happy at the moment and cant afford getting the tc 5400 up and running yet. Its a mtx sw1515 and it does not like deep output and seems to have a steep roll off at around 30hz. Anyone have an idea how I...

    I am in the midst of trying to finish my theater space. It is at the point where the shell is constructed, the wiring is done, and the stage with the baffle wall is nearly completed. Notwithstanding the fact that I'd have to take it all apart again to paint it, I could hook up all 7 speakers...
  11. sms-1 manual tuning has no test frequencies

    SPL Meters | Mic's | Calibration | Sound Cards
    I have been messing with the sms-1 with my klipsch sw310 to see how it works before I start messing with the DIY subs. I can get a test sound with the auto EQ but when I go into manual there is no sound. I type 12345 to get to the main sound screen, same place as the auto EQ test sounds but...
  12. Live Tuning?

    REW Forum
    I'd like to be able to do some "live" crossover tuning by using the RTA, but I need to be able to see historical readings since it refreshes way too fast. Is there a better way to do that, I'm still exploring the program. Otherwise it's adjust, measure, and repeat. The way speclab does its...

  15. Fine tuning my sound

    Home Audio Acoustics
    I have had my room completed for about a year now and I have never really felt like I am getting the sound that I should be getting. I just do not feel like the surround sound definition is really there. To be honest, I am not sure how much of that is due to my speakers and how much of it...
  16. Tuning BrilliantColor

    Home Theater Projectors
    I have a love/hate relationship with BrilliantColor. My projector(Acer 7531D) has on or off settings. With BC on, sometimes things seem more natural, I see less rainbows, brighter image....but it also seems to add a lot of yellowness to the image. I have gain controls for RGB, and when BC is on...

    I am Biamp AudiaFlex certified. I have a lot of experience with programming DSPs but have never had to tune a system (most of the work I do is for courtrooms where some basic defaults sound pretty good and only voice is usually involved. I have been contracted out to tune a few auditoriums...
