Is DEQX a game changer?

Lewinskih01, If I remove the time alignment, imaging and soundstage collapses to a much flatter representation - something I hadn't fully appreciated until I included DEQX in the chain. Recordings which include original acoustics sound quite stunning when DEQX has time aligned all drivers and frequencies

For a three way system + subs you would need to add something like mini DSP for 8 channels as one DEQX unit will only cover 6 channels (ie HDP-4). Use DEQX on the main speakers where the benefits are most significant and another device to time align the subs. Alternatively, leave a passive crossover between treble-mid or mid-bass on the main speakers and use the remaining two HDP-4 channels for the subs

When an initial DEQX measurement is taken, the software will attempt to correct whatever it hears so if there is a passive crossover in the chain and any drivers are out of phase or timing, it will automatically correct that in the calibration it makes. Doing this process outdoors 'anechoically' produces the best results

Subsequent time alignment to subs and then room equalisation will enable you to remove almost all the damage done by your room so whatever speakers you listen to will perform closer to optimum, as Bruce has experienced

FYI:

Just got a letter to Marc Mickelson of The Audio Beat published, here:

I hope Marc gets around to reviewing the DEQX.

I can't overstate how important and decently priced this piece of kit is for one's audio toolbox. Considering what some are willing to pay for cables and other tweaks, when one considers what the DEQXC can do, it's a no-brainer decision, IMO.

Thanks Bif, very interesting.

It really seems ridiculous to make a product that requires a rep to get it to work to its best. What about a power outage?

Though I think the product has merit, I will wait for a more user friendlier version.

Power outage should not affect the DEQX which stores the information. I have disconnected mine, stored it for weeks and, upon reconnection, it ran as it was. In addition, all the information is stored on your local PC and can be uploaded to the DEQX if necessary.
