  1. REW Forum
    First of all: 1000 Thanks to the authors of the great tool REM! I am exploring the functionality of REM and got stuck in computing the Thiele Small Parameters. I've made the following measurements: free air: +10g The result is then the following: That is odd, since fs is clearly lower...
  2. Home Audio Acoustics
    Hey HT shack, I'm forced to listen in a less than perfect position. The rear wall is only ~4' behind my ears. Usually I would diffuse the area behind me, but since 4' (or even 5') isn't enough distance for effective diffusion, I thought it might be better to use some 8" broadband absorbers...
  3. Home Theater Design and Construction
    Hello folks, Long-time projector fan here. We have enjoyed the big screen for 8 years, but my first projector decided it doesn't want to power up any more and Optoma informed me they don't have parts for it. It was an Optoma Movietime DV10 (Circuit City Black Friday deal - $450 for projector...
  4. Home Theater Receivers | Processors | Amps
    Well my X4000 has began resetting all the time so I'm sending it off for warranty. In the mean time I bought a X1100W to use (I bought it for the wife for her TV downstairs to use w/ the tiny NHT speakers I used previously) Needless to say... going from the X4000 as a preamp/processor and...
  5. REW Forum
    Hello everyone, I was hoping somebody might be able to shed some light on this topic. I am a custom car audio installer by trade, over the past couple years I have found a way to make my job exciting and "new" again. REW has played a significant roll in this newfound excitement. I've discovered...
  6. Home Theater Receivers | Processors | Amps
    :help:I am wanting to run speaker level outputs (Front L/R) from an ~95watt Sony STR DH720 into a QSC USA 850 (Input Impedance:20Kohm balanced & unbalanced "non-inverting" [??]", or 20k ohm "inverting" .... quotations mean :dontknow:. This looks like a helpful site...
  7. Home Audio Acoustics
    Any help / input will be appreciated:- 1. I have a slightly L- shaped room and the ceiling on one long-side of the room slopes at the edge. For better acoustics, I am thinking of turning the room into a rectangle and incorporating the exact same slope on the opposite corner of the ceiling. This...
  8. System Setup and Connection
    I currently have a Rotel RB1070 powering my mains, I've just received a Rotel RB1080 to replace it. The 1070 has an input level of 1v, the 1080 has a sensitivity of 1.5v. Am I correct in assuming this will have an effect on the output level of the main channels? My SPL meter is out of action...
  9. Ported Subwoofer Build Projects
    Hi all, I have "stood down" my ambitious plans for a monster Tapped Horn for the moment. Instead I built a 24" cube sealed box for 2x 15 inch Alpine SWS-15D4 and it works ok, clunky bracing not withstanding. It is a "test mule" somebody called it, over at the Other Forum That Shall Remain...
  10. Home Theater Receivers | Processors | Amps
    Hey folks, figured I'd drop in and do a brief write-up of what I experienced with my recent component upgrade; I replaced my AVR head unit with a bigger model. As the title says, I went from a Marantz NR1402 to a Marantz SR6007, as I am revamping the system in the bedroom, and plan to move the...
  11. Computers | HTPC | Media Servers
    I'm so new to setting this HTPC up, I'm not sure what even to ask, so here's what I have and what I want to do. I want to: -use J river to organize my music and movies from my couch upstairs -use my existing PC (win 7) and 2 TB HD that is downstairs -use my Onkyo 818 as the AVR upstairs -use...
  12. System Setup and Connection
    I have a brand new zbox which works great on a monitor via the Display Port to DVI connector included in the package. But i just bought a DVI -> Component cable from Monoprice, and my receiver doesn't seem to want to recognize it (Integra 5.5). I plug other things into those ports, and they work...
  13. Audio Processing
    Okay, this may be an odd question. I just want to get some feedback if I'm on the right track. Assume I have a source material mixed in the ITU 7.1 standard (30 degree separation from Center of FL/FR, 110 for SL/SR, 150 for RL/RR.) Now, I want the panning to work for a physical installation...
  14. REW Forum
    Hi all, I think that this can be done, but I just want to be sure. Can REW produce an impulse response file that contains room corrections that can be fed directly into the foobar convolver? Magical if it does....:bigsmile:
  15. DIY Speakers
    I am intrigued by DIY speakers. All of the options, shapes, finishes, presumed value interest me. Unfortunately, I am just starting out and have zero tools or experience. I do not have any cabinetry experience or wood finishing experience. I do not own a table saw, router, clamps or...
  16. Subwoofer Amps | High Pass Filters
    My sub build is coming along nicely, and I'm working on getting the power side of it figured out too. The problem I'm having is that it seems I can't get a signal from my Denon 791 receiver to go into the pro-audio stuff I hook up. It works fine for my itty bitty subwoofer with a plate amp, but...
  17. SPL Meters | Mic's | Calibration | Sound Cards
    So I guess there's a debate whether or not to include a preamp in a soundcard calibration file. In my case, I have an EMU 0404 PCI interface and a GT Brick preamp. According to REW instructions, I'm supposed to just plug the output of the soundcard directly into its input. However, I'm certain...
  18. System Setup and Connection
    Hi everyone, this my first real post! I really hope you guys can help me out with this one. I have a 2009 MacBook Pro with Windows 7 installed so I can use an external Blu Ray drive, and basically turn my laptop in a part time HTPC. I also purchased a Pioneer vsx 520-k Receiver, and Optoma HD20...
  19. DIY Subwoofers - General Discussion
    Dual mono subs => splitting and design questions I'll be making two seperate subs. They will be connected: Receiver (sub out) -> behringer dsp1124 -> stereo PA amp -> subwoofers now is my question, where and how do I split the channel? My thoughts were RCA (receiver) -> 2x XLR (thus using...
  20. Creative Sound Solutions
    hello, I'm building 2 subs using a CSS SDX-15. (thus 2 seperate subwoofers!). I will go with either a 120l closed design, or a [email protected] ported design (still have to decide). However, I'm currently looking into an amp that will be able to drive these babies... Pure spl is not important, it...
