I don't know why, but I'm excited about new versions of the amplifiers. If I can make my EP800s v4 by switching out the amps, I think I may be able to swing that kind of upgrade. I have trouble imagining a performance improvement, but half the fun of a hobby is wasting gobs of money on it chasing an impossible ideal. Right?

I kind of like the idea of a digital volume control instead of a dial, but I have no practical experience with one. Remote control would be nice, but like I said, I'd rather have a device that's designed to handle multiple subwoofers and tactile transducers, and then have a remote control for that one device.

Andrew, I know it's too early for you to really tell us what you're focusing on with the redesign, but I hope you don't mind my babbling. I figure it can't hurt to throw the ideas out there, harebrained as they may be.

I think there are several of us who are kind of wondering this, what a surprise right?... I was also wondering if our data has been helpful at all thus far?

I'm also planning a sub upgrade in the near'ish future. It would be nice to have an idea on what may be the horizon.

I believe it will have an new option.

A toggle switch that lets you choose if it runs in full mode where it acts as a localized EMP weapon or at half strength where your electronics don't have to be moved to the other side of the room but you will disrupt migritory bird patterns.

No no no. It'll be equivalent to the EP500 only at half the price. smile

What Axiom subwoofer(s) do you own?


I am going to include my two systems and another two systems I have set up for my brothers recently.

EP800 and 2 F113 Fathoms

EP600

2 Velodyne DD-18s

Where do you have the Level, Frequency, Phase, and Subsonic Filter (if applicable) controls set?

9:00 on EP800, 11:00 on F113s, 8:00 on EP600 11:00 on Velodyne DD-18s

Phase set to zero and subsonic filter off on Axiom subs. All controls adjusted in receiver/preamp when possible. Except for Fathom parametric control at 25 hz and phase at 45 degrees. And Velodyne DD-18 which have extensive onboard parametric and phase control (SMS onboard).


How are you connecting your signal source to the subwoofer (RCA/XLR/High Level)?

RCA to EP 800, Velodyne DD-18, EP600
XLR to FL113s

What receiver/processor/pre-amp/integrated amplifier are you using?

Pioneer VSX42 with EP800/m22s
Integra 9,8 with Fathoms/M80s
Onkyo TX-nr717 with Velodyne DD-18/M80s
Onkyo TX-sr876 with EP600/Totem Arros

What are you using for your main speakers?

see above

Where do you have the crossover frequency and trim levels set in your processor/receiver for your main speakers and your Axiom subwoofer?

50hz and -2 with M80s/F113s
80hz and -5 with M22s/Ep800
100HZ and -5 with Totem Arros/EP600
50HZ and -5 with M80s/Velodyne DD18s


Are you using the trigger on your subwoofers? Yes

Very happy with all systems.

Something to consider would be some kind of parametric equalization adjustment or slope adjustment in the 25hz zone such as can be found on the Fathom F113. This feature is very useful in many rooms for additional control of boundary reinforcement in the lower octaves.

If some parametric equalization is not possible, then perhaps consider reinstating the room trim adjustments found on the Axiom V2 subs. They were useful and better than no room adjustment at all. One last thought is that high level inputs are somewhat antiquated especially in modern HT systems so I question whether they should be continued.
