Is DEQX a game changer?


Just read a bit and it sure sounds interesting. Does it sound like the best way to upgrade speakers?

Hi Guys, I have read several post, but not near all, this may have been addressed. I have no doubt that the DEQX could be a game changer, but it would require Biamping, triamping etc.
The biggest problem in any speaker is the crossover. Coils suck the life out of music. If you are willing to remove your speakers crossovers, run an amp channel on each driver, properly set up the electronic crossover, then adjust time delay and eq to your room, there is no doubt that any of us will have performance that we have only dreamed about.... assuming that the DEQX is clean and does not mess up the sound of the other electronics in the system. Unfortunately for me, this is a product out of my reach... I have found a substitute that I will be trying shortly, it is called Mini-DSP... I have purchased it. It comes in 2 to I believe up to 10 Channels... I have gutted my speakers crossovers, but have decided to do some cabinet work so it will be some time before I get it all up and running... I can't imagine the Mini DSP doing anywhere near the job of the DEQX, but it does have full electronic crossovers, full eq capabilities and full room correction software with a calibrated mic available. I'm excited to give it a try and very curious to see if anyone else has tried this inexpensive product?
Thanks, Tim
Hi Al,
Thanks for the reply. When building speakers, we time drivers are not time aligned on the frontal plane by adding padding/baffle step compensation to change the delivery of the tweeter and mid hitting your ear at the same time. This is built into the crossover. An External device cannot change that as far as true timing speed is concerned. Using a 2 way as an example: When bi amping, you can change the delay of the response of any driver to properly align when the response of each driver will hit the ear.
What the DEQX would have to do is send a delay of given frequencies of one driver or the other to compensate for the work that has been done in the crossover....
My point was more that by completely removing the crossover, you should gain the attack, leading edge info and detail that hundreds of foot of copper coil can diminish in a crossover. There should be no comparison of the speaker with a crossover vs without. Any multi driver speaker with a DEQX with proper delay and room compensations tailored and the passive crossover removed should be a whole new world compared to the same speaker with the crossover left in tact. Theoretically, you should be able to take any 2 or 3 way with quality drivers and customize the DEQX settings (eq out the bumps, bring up the dips, time align, eq for room) to be a world class speaker system. Yes, it can certainly help a speaker without removing the crossover, but even with the best speaker systems available, if the DEQX is biamped (2way) there should be no comparison.
Hi Al, yep, Oh, absolutely. You can increase delay, but you cannot decrease the delay. If any designer ever over compensated with Baffle step compensation or match pad, you cannot remove that resistance or speed up the passive parts inside. On the other hand, you can add delay electronically. What I have loved reading about the DEQX is that once mic'd, it will automatically adjust time delay and help eq... This is a tremendous benefit. I would also suggest that you take your current crossover points and try taking a listen at very steep slopes, say 48db per octave. On some speakers that alone can make things more coherent and easy enough to reverse if it doesn't work out. Good Luck with it, Let us know how you like it, Tim
The comment to use steep crossover slopes is for those that can bi amp that still have their crossovers in place.... sorry for any confusion.
