Axiom Home Page Forums General Discussion Home Theater EP800 experiences

Hi SRoode,

Thanks for the detailed feedback on your EP800 experiences. I'm just writing a piece on the EP800 and may quote you in the Axiom AudioFile newsletter.

Interesting as well that you took the BFD out of the loop and got such excellent room response. Incidentally, on the abbreviation front, what is REW? (In another era, that meant "Rewind"!)

Regards,

Room Eq Wizzard Alan, it is free software you can get from Home Theater Shack to graph your room response, and apply filters, etc.

I see Rincewind is expanding his activities.

My understanding is that it's the separation between drivers (or between driver and port) which helps to smooth out the response. A bit like having two subs in slightly different parts of the room.

I suspect this is why the SVS cylinder subs seem to sound a bit smoother than their response curves would indicate; the ports are about three feet away from the woofer...



Wow...

I think that's what I was getting at. Since there are now 2 drivers in each enclosure instead of one (each about 14" apart on center), and since the drivers are now significantly higher than the EP500, I'm wondering if that helped to smooth the response out.

Alan,

Randy is correct. It's a piece of software to help expedite the tuning process.

Please accept my thanks for helping to turn out such a wonderful sub. Please FF my comments as you wish to the newsletter!

Well I'm a little late to the party because the first sub was damaged pretty badly in transit (thanks Fedex) and had to be replaced, the replacement arrived yesterday. I find the amount of bass to be quite smooth yet dramatic even in our fairly large room (admittedly with limited seating, one couch), I suspect the two drivers may be a help there but we've never had a sub before so that's just a guess. I have to say I'm glad I only ordered one because my wife's comments so far have been "it's too intense" and after the first sub stopped working she expressed relief, "It was like an earthquake in the living room, I thought I'd never get used to that rumbling."

Well fortunately human nature is adaptable and I suspect/hope that after she grows accustomed to the sound she will begin to enjoy its musicality, however, in the interim my daughter and I love the sound and to me it indicates that a single EP800 can be capable of quite an impact in a fairly large room (7300 cu ft) such that many users may find themselves quite satisfied with only one, I mean on DVD or Blu Ray the LFEs have been simply spectacular ("like an earthquake in the living room") with no particular sense of unevenness or excessive boominess.

Have you calibrated it yet with a RatShack meter?

Your wife might be right (gasp!) and you might find that you're running your sub +15dB hot.... as many first-time sub owners do.

It really shouldn't be thought of as a seperate source in it's intensity...but rather an extension of your mains.

That said, many (myself included) DO run subs 3~5dBs "hot" because we simply like it better that way!

Ditto that. I'm all for "encouraging" the wife to adapt before turning the sub down.

So far I went with the Audyssey calibration and I would actually prefer to run it a little hotter because it seems a bit tame (although it also seems pretty accurate and balanced, sounds quite good), but now might not be a good time. When you calibrate with an spl meter to calibrate the system, don't you have to run tones at a lot of different Hz? Still haven't explored the whole manual calibration thing in much detail.
