I thought I would open a new thread for discussion of Axiom subwoofers in general, and the development of the next generation in particular. With all that has been learned during the design and engineering of the new amplifier line, it has naturally lead us towards looking at our subwoofer amplifier platforms to see what improvements might be possible. To do this is going to require a better understand of how you are using your subwoofers, and with what types of partnering equipment. So, I'd like to start off with a serious of questions which I'm hoping everyone will answer and share with us and the group. You never know, your answers to these questions might allow us to make some significant improvements to the future Axiom subwoofer line-up!
Now, on to the questions:
What Axiom subwoofer(s) do you own?
Where do you have the Level, Frequency, Phase, and Subsonic Filter (if applicable) controls set?
How are you connecting your signal source to the subwoofer (RCA/XLR/High Level)?
What receiver/processor/pre-amp/integrated amplifier are you using?
What are you using for your main speakers?
Where do you have the crossover frequency and trim levels set in your processor/receiver for your main speakers and your Axiom subwoofer?
Are you using the trigger on your subwoofer?
Many, many thanks for your input!
EDIT: I am going to open up the survey to include ANY subwoofers, not only Axiom models, so please participate.
I also wanted to add that if you are not comfortable revealing the other aspects of your system, for whatever reason, you can happily send me a direct message.

What Axiom subwoofer(s) do you own? EP500 (also a Polk 10" sub to be replaced by a second EP500 soon I hope).
Where do you have the Level, Frequency, Phase, and Subsonic Filter (if applicable) controls set? Level 11 o'clock, freq is at highest (150Hz if I recall), phase 0, subsonic off.
How are you connecting your signal source to the subwoofer (RCA/XLR/High Level)? RCA.
What receiver/processor/pre-amp/integrated amplifier are you using? Denon 4311CI for surrounds (I have a 7.2 setup), 3 ch ADA1000 for VP150 and M80s.
What are you using for your main speakers? M80
Where do you have the crossover frequency and trim levels set in your processor/receiver for your main speakers and your Axiom subwoofer? I calibrate with Audyssey. LFE is at 120Hz. I set the M80s as Large. I leave the trim at the Audyssey setting for the M80s but bump up my two subs by 6db.
Are you using the trigger on your subwoofer? No. I have had problems with it in the past.
For every expert, there is an equal and opposite expert.

What Axiom subwoofer(s) do you own? 2X EP-600, with a 3rd in the works.. Where do you have the Level, Frequency, Phase, and Subsonic Filter (if applicable) controls set? the above settings are mostly the same on both, so i am only listing them once. Level- 12:30, Frequency-80hz, Phase-180 on one and 0 on the other, Subsonic filter-on How are you connecting your signal source to the subwoofer (RCA/XLR/High Level)? currently using RCA's, I tried XLR, and i believe Brent talked with you about this Andrew.. The gain on the XLR input path on the current amps is 6db or so lower than the RCA's.. The XLR input on the current amps is pretty much unusable due to the difference in gain, which results in a VERY reduced max volume. What receiver/processor/pre-amp/integrated amplifier are you using? Krell HTS 7.1 What are you using for your main speakers? LFR's Where do you have the crossover frequency and trim levels set in your processor/receiver for your main speakers and your Axiom subwoofer? Cross over is set to 80hz for the Subwoofer within the processor Are you using the trigger on your subwoofer? Not using the trigger due to issues. Many, many thanks for your input! No problem, glad to help....

Are you using the trigger on your subwoofer? I'll go ahead and answer these, but several of the answers will change as my addiction to upgrading continues to play itself out. 4x EP800 Levels are between the 8 o'clock and 9 o'clock positions. 150 Hz. 0º. Subsonic filter set to Off. Receiver has two RCA subwoofer outputs, so one is feeding one pair, the second is feeding the other pair. Onkyo TX-NR708 LFR1100 40 Hz for main speakers. LPF of LFE is 120 Hz. Trim level for front left is +0.5 dB, front right is -1.0 dB, and subwoofer is -2.0 dB. I'm not using the triggers. As I said, though, it's a moving target. I'll be looking to do a lot more tweaking when I move my system, and I do plan to upgrade my receiver within the next year, probably, perhaps back to a preamp-processor with XLR connections.

Also, I'm excited to see what Axiom comes up with for the next generation, even if I may have to sit it out.

Oh great! I just ordered two EP500's...
Well I can answer most of the questions even though I haven't received the subs yet.
2 x EP500 1pr M22's as mains
RCA, Denon 3808CI, Crossed at 80Hz, highly unlikely to use the triggers.

This is all GREAT information everyone!
Note that I have edited the original post to open the survey up to all subwoofers, not only Axiom models.
I am also intrigued and surprised that three of you have mentioned issues with the trigger. This is news to me, so more specific information on why the trigger did not work in your system would be appreciated!
Thanks again,
Andrew
