Hello. I am a lover of music of all styles but very attached to the quality of the sound. I built my stereo little by little with as a base high-efficiency diy speakers: Supravox 16" EXC 11V in bass reflex 200 liters and compressions Radian 950pb with horns Araï 290FL. Dcx24-96 active filter, digital FLAC source on JRiver, separate bass-treble amplification.
After long months of study, tweaking and testing, I got a hi-fi system that works well, with superb bass and well-detailed treble, working on all styles of music. Today I feel the need to measure my installation, to see if it is consistent, and where I can make improvements (treatment of the room). REW seems to me to be the ideal tool for this

Hello Eric and welcome to the forum. Sounds like quite the setup you have DIY'd. :T What amps are you using for your treble and bass?

Hello, sorry for this long silence on the forum. I have little time because of work.

sorry for the horribly late response to chrapladm: the power amplifier for low frequencies is a Hypex Ncore 250 that gives 125W under 8 ohms

The power amplifier for high frequencies (Radian 950pb) is a clone of Nelson Pass' AmpCamp class A 2x15W

here a photo of the cabinet (diy) with at the bottom a 2000vA current symmetrizer (DIY too), the two laboratory power supplies for the excitation bass speakers, the DCX Behringer and an SRC (to add a turntable later)

all connections are balanced (neutrik) and cables of professional type but at a very reasonable price (Mogami, Belden, Canare). Everything is DIY

Regarding REW, it took me a long time to set up my sound card (Focusrite) and get the first curves. I am not at all an expert in computer science or acoustics. For the moment I have measured a response curve in the near field and at the listening area.

My approach was to make measurements of the speakers in near field, measurements of frequency responses of the bass speaker and the treble speaker, to check the cut-off frequency. Then I corrected the near-field curve by equalization with the dcx (and simulation in REW).

Hello, the small A/B box is a speaker selector that was to be used for adjusting the length of the vents when listening. I've never used it until now.
