Good to read some posts here from people who use the Devialet with subs. I have a pair of ELAC Sub-2090 (although one is playing dead now). When I bought them 4 years ago, I spent hundreds of hours learning on how to set them up properly and bought the XTZ Room Analyzer Pro II kit to help me.
There seem to be two schools, one who recommends using mains full range (REL and PS AUDIO for example) and the other that insists that only using HPF for the mains will give proper integration (JL Audio, www.acousticsfrontiers.com). Since the Devialet provides this option, I went with the latter and practically created a three-way speaker with bi-amping if you like from my two way YG Acoustics Carmel. The two subs were close to the main speakers and crossed (both HPF and LPF) at 80Hz.
All subs, especially the ones with DSP, like mine, will have some delay, somewhere between 3ms-10ms (possibly more even), I found that time aligning the subs was critical to get the best results. Depending on the delay, this means that you either place the subs a little bit behind the mains, or a lot behind the mains. 10ms means about 10 feet. Usually, this is worked around by adjusting the "phase" but that will alight the speakers at the crossover frequency and close proximity (reg the frequencies). Plus, as the name suggests, it is phase aligned but not time aligned. To be able to do that, you have to delay the main speakers. Luckily, with the Devialet, you can also do that. It took me about 3 days (about 8 hours) to properly do that with a lot of measurement but a lot of time was spent on the online configurator...
Subs were set mono btw, for better room mode cancellations. I got a nearly perfect result with above 20Hz-20kHz with +/-5db (not bad for a small room) and RT60 0.23-0.4 throughout.
Now, that one of my subs died, I have to start all over again. For now, I got good enough results regarding measurements but the sound is less convincing. To make sure I don't get directional bass from the sub, I lowered the crossover freq to 50 (both high and low).
I'm wondering now if I should either increase it back to 80-ish and see if I can localize the sub or should perhaps try running the mains full range and just use the sub to extend bass? My main spks go down to about 35 Hz (+/-2db) both in the specs and measured in my room. If I run them full range, where should I set the crossover for the sub? Also, what order is recommended? So far I have only used 2nd for both low and high as somebody here measured a few years ago and that seemed provide no phase shift. But that may not be important if I run the mains full range.
Anybody else tried to integrate their sub(s) using the active xover in the Dev? Or any suggestions regarding the above?
