Sloped baffle

Practically, headphones are the best for time and phase coherence. Even good quality cheap ones. Use those as a reference to help decide how good speakers sound in this regard. Then check the measurements if available to see if things correlate.

Bombaywalla, I use the DEQX, and I can tell you its tranformative. Because it 'corrects' the drivers, it has a way of making different speakers sound more similar, which would no doubt be disturbing to some potential users. Also, it makes some recordings sound somewhat different than we are used to hearing them, which is something that also takes some getting used to.

Hi Psag,
What you are quoting makes absolute sense... If you pull the crossovers and make everything perfectly phase and time aligned along with perfect frequency response, then the only difference is sound between speakers is the materials themselves...ie, how does the box sound, what does a Kevlar cone vs a paper or aluminum cone sound like etc.... So you are hearing first hand, (by correction) how important a flat response along with phase and time alignment can be.

Even with DSP, bet there's still a market for $300 Revelators vs. a $20 Silver Flute and vice versa.

Psag ... just took a quick peek at the DEQX web site. Very interesting.

Problem is that it's not cheap and where is the vendor located? What recourse if it doesn't work well.

Also, it obviously entails inserting an artifact into the signal path, presumably between source components (e.g., CDP, DAC and phone pre) and linestage. Oftentimes, not the best thing to do. How does it work if one has an integrated amp with built-in phono section??

Sure wish I could try the device on approval.

Cheers,
