Axiom Home Page Forums General Discussion Home Theater Dual EP800 vs SVS Ultra 16

When I got mine, I tweaked so many things I couldn't possibly make heads or tails if it was break-in or changes to parameters and environment. I am positive however that temperature changes in my space affect the sound.

I am in the same boat. I am always making adjustments, and it is impossible to determine what individual change has made the most significant difference when multiple changes are made simultaneously. I should be more regimented in my methods but the end goal is always better sound and not determining which change has the most effect. I enjoy playing with the sound ALMOST as much as listening to the music.

I never considered temperature and may have equated differences heard to other factors. I will give special attention in this regard from now on.

Temperature seems to have an effect, I would agreed.
With respect to break in time, my first set of M80's really opened up a short time after I turned up the volume. I had babied them for a week or two then got a little braver as time went on.

Temperature, barometric (atmospheric) pressure and input power have a great effect on loudspeaker response. The magnitude and phase response of passive filters in traditional loudspeakers change with temperature and input power and also time (component values drift). The driver characteristics change as well.

Digital filters don't suffer from these problems. Phase response is linear and pass-band ripple is pretty much nil under all conditions. Amplitude and frequency dynamic range are an issue though and have to be carefully designed for in a digital filter. Couple a digital filter with feedback incorporating each driver's condition and you'd have a very expensive but maybe better sounding speaker.

Maybe though a better use of time and money is to use digital filters to compensate for deviations in the family of curves. That's what Axiom is doing for Bryston and will soon do for the LFR1100s as a purchasable option.

Having said all that, I don't know why I am hearing poorer sound in my environment as the temperature climbs. There may be effects I am not aware of like eddy currents and the like in my room.

I used to tweak a ton in my main room. Since I re-configured it, I no longer have a propensity to tweak. I also have a secondary listening area that Serenity_Now helped me with. I found I didn't have to tweak that environment at all.

Incessant tweaking could indicate a deep satisfaction with your environment.

My ultimate tweak. I went so far as to remove walls to enlarge my space predominately for the purpose of improved sound. My main floor laundry room is no more. Each trip to the basement to wash cloths is a reminder of how much I appreciate quality sound. Not sure what that says about me.

It says you recognize there is no substitute for a larger space. My 80s are 9' apart, 6' away from side walls and I sit 14' back. It's bliss.

It says your a wise man indeed. Cant be having that noisy washer and dryer interfering with your pleasure.

Anyone who needs a dump run to improve audio is A-OK in my book! . Mattman built a room around his LFRs as well. But he is modest about showing it off.

Would love to see pics.
