For primary studio monitors, I use active 2 way with analog active crossovers (Mackie HR824) for accuracy and revealing detail. My studio sub, when I use it, is fed with a digital crossover (MiniDSP). While I like the programmability of a digital crossover, I don't fully trust it for the mid...

The meeasurements for the dimensions of a control room must be for where the hard physical boundaries are. Where you sit MUST be on on the center line of the room, and the monitoring environment absolutely MUST be symmetrical to the line going from front to back where you sit. Any treatments...

Any acoustical measurement with enough power to be truly useful will require any non-technical user to spend some quality time climbing Mr. Learning Curve. Having been a professional studio technician and recording engineer, I too have been learning about the proper use of REW.

As the room gets smaller, correct acoustical treatment becomes more difficult. Liveness can be nice if the room is BIG, and most of the rooms in ordinary homes do not qualify as big enough. Sadly, in a "small booth" situation (particularly for recording VoiceOver), "kill it dead" is the only...

Actually, the fact I stated is very old news, and widely understood. I first learned about this problem over 30 yers ago working as a studio tech. A few years before, there had been a big thing of using 1/3 octave graphic equalizers to correct response in control rooms. The studios that tried...

My response would be "it depends". Is the internal DSP only for response correction (for the room), or does it also serve as protection for the driver of the sub? If the sub is ported (as most are), below the port resonance the cone motion is not controlled by the box, and putting power into...

This is correct, up to a point. The room modes, meaning resonances dictated by room dimensions, get closer together as you go up in frequency, until they blur together enough to smooth the frequency response. The room modes mostly come into play below 300 Hz or so. I would also point out that...

I use an older Denon receiver. Can't speak to your specific model of speaker, but I can tell you that most of the center channel speakers I have seen have the "MTM" design, which does not tightly localize the center. I fought back by making an extremely ugly looking center channel speaker by...

Your best and most cost effective choice for broadband absorption (bass trapping is different) is standard fiberglass roll unfaced wall insulation, the deeper the better. Not less than 6 inches thickness, and thicker is better. My preference is that attic blanket stuff. What you do is wrap a...

I will be using REW to test and set up monitors and subwoofer in my studio, possibly also using a MiniDSP 2x4 balanced for processing and crossover to sub. But before I pull the trigger on hardware, I need to know whether I can make UMIK-1 work in conjunction with the setup that drives my...

Judging by what I see, there is probably more than one problem. First, there is a very good chance that your midrange driver is more efficient than your woofer. This does happen sometimes, and I must admit that I don't know why speaker designers let that go by. The smaller peaks and dips may...

As a recording engineer and studio tech, I can tell you that some recording studios has flirted with and then rejected room correction before 1990. A room creates time domain problems that cannot be corrected in the frequency domain. I can also tell you that ALL rooms have room modes...
