Digital speaker crossovers and room correction discussion

--- Quote from: HAL on August 10, 2017, 06:14:28 AM ---So far the list of DSP based crossovers has been:
Behringer DCX2496 (own)
DEQX 2.6P (own) (and newer listening to demos)
MiniDSP (listening to demos)
Danville Signal Processing dspMusik LCD (own)
Perpetual Technologies P-1A for SOCS (own)
Room correction:
MathAudio RoomEQ (own)
Dirac (listening to demos)
Room measurements:
Room EQ Wizard (use)
CLIO (own)
CLIO Pocket (own)
MMK speaker measurement system (co-developed)
Presently the best sounding of the group to me with the Megalith speakers here and others tried is the dspMusik and RoomEQ. Both have easy setup capabilities and very flexible.
Only takes very simple measurements to get RoomEQ working and sounding very good in my room.
Not heard everything, but have heard other systems as well at shows.
To me the most audible part of great DSP crossovers is the ability to capture the soundfield with very accurate channel to channel crossover matching that is extremely difficult with passive components due to their tolerances. When accurate time delays are needed, it is very easy to add.
I use room correction as part of room tuning. First are the acoustic treatments (absorption and diffusion) to correct for the normal room bounce problems and bass absorption. Then use RoomEQ as the last step to integrate the speakers and room. Done this way has given excellent results in my system.
Hope this starts a conversation.

Rich,
You mentioned using room eq as the last step. Wouldn't excellent software be able to correct for deficiencies without using acoustic treatments? Also, I was on the Amarra site tonight which is Windows compatible. It seems to be a Swiss army knife of sorts. Your thoughts on it?

richidoo:
Room correction only fixes the spot where you measure. Treatments affect the whole room.
HAL:
To me room correction with treatments helps to minimize the need to use software correction. Have heard both methods with full room treatment only and systems like Tact/Lyngdorf without room treatment, but it sounds more natural to me with treatments and then correction.
The correction systems have a limit as to how long they can correct the response. Any room artifact outside that will not be corrected. This is another reason to minimize the room artifacts to begin the process.
I have not used Amarra, so cannot comment. Others may have and would be good to see their comments. I run Foobar2000 with RoomEQ as the player and room corrector. Keeping the user interface as simple graphics is good from my experience.
Nick B:
Thanks, Rich(es),
As you are both of the room correction first method, that works for me. I'll order a mic and do the testing.

How fine of adjustment can be had with a digital crossover?
