Axiom Home Page Forums General Discussion Stereo Sound Quality (Price not important): M60/80 vs...

Let's see the science (curves).

So... here's a link to the page with the graphs of impedance, etc...

Not sure if that says anything to you guys? Look the same pretty much?

Any thoughts on these graphs? These speakers look pretty much the same to me (judging by the graphs). Only a very slight variation (nothing I'd assume my ear could 'hear').

I think I'm on my way to being an M60 owner (non HP). Probably spend the extra $s on a power amp.

There is a slight increase in output at the lower frequencies. If you look at the physical attributes of the HP woofer it has a much larger surround which would indicate it has a longer Xmax which will allow the speaker to move further and have higher output. Now if you plan to use a subwoofer at any point then you don't need this extra output plus the sub would take a huge load off your main amp. It is the bass that consumes the most power from the amplifier so using bass management will allow the sub to take over those duties. Now if your a bass head like me you would do one of 2 things, get the HP's or add a sub. I know I have already said this but if your sticking to straight 2 channel listening I say go for the HP's. Tam will tell as I will also , I use subs with my 2 channel listening since my mains don't have much output below 60hz and I really like the way it sounds and the subs blend really nice so those are your choices. It seems your are really having difficulty with this final decision hopefully this will help sway you one way or another.

Ditto on 1 sub per channel in a 2 channel system.

I don't use any LFE control as my tube amp doesn't have that feature. Attaching the sub(s) to the Amps' Speaker Out connectors gives true 2 Channel, even in the low end, although common wisdom says that the low bass is mono anyway. I have several CDs where this is definitely not the case...

Those curves say that if you are going to listen at "sane" levels, stick with the standard.

If you want to listen at insane levels, you need to ask Axiom for a different set of curves. You need the curves for 105 dB and above. Those curves will likely show that the standard driver compresses while the HP driver keeps on going.

My advice continues to be go with the standard and save your money for a sub in the future. Even better, use the funds for room treatments.

It is essentially the same, the graph shows that the lower level sounds are sustained easier by the High Powered Drivers. The flatter line with out so many dips.

I ended up going with non-HP, based on the response curves seeming to be flatter in the low end at the SPLs I usually frequented. Need a pair of HP's to be sure I did the right thing though. Sigh.
