Axiom Home Page Forums General Discussion Advice from Axiom Owners Why make Vp180 HP?

I'm curious why axiom choose to make the vp180 HP as a lineup if you would crossover to a sub at 60-80hz? I'm I missing something here? The reason why I asked because I have the m80 HP and a vp180 standard and was thinking about upgrading to the HP version.

For those who are pumping huge amounts of power into their centre and are concerned about dynamic compression below some frequency. Axiom has never defined "huge" nor the frequency. When crossing over at 80Hz, you absolutely don't need an HP driver. But for anyone crossing over at 40Hz, they might want to check with Axiom.

I tried crossing over below 60hz on all three front speakers and seem like you are losing a lot dynamic bass on scene like big explosion. Crossing over at 80hz for all speaker sound best. I find the HP benefits from running 2 channels full range for music, makes the speaker sound very good but I find it a bit too boomy. Still unsure why axiom offers the HP for the Center. 3 channel music?

80% of audio depends on the room just like 80% of fitness depends on how and what you eat and drink. 80Hz crossover sounds good in your room but in my home theater 60Hz sounds best. Others may cross over lower and hence may want the best possible fidelity at elevated sound pressures which may push them to HP drivers. I surmise the HP drivers came out of the Bryston Model T research which Axiom subsequently decided would be a good idea to incorporate in their models to limit low frequency dynamic compression at higher powers. We have to remember that just because a speaker is rated at 400W, it doesn't mean it's linear to 400W. It just means it can consume that power without damage.

I still don't see a point for Home Theater use. Does anyone out there own this model care to share the reason for choosing this over the standard?

Because as I've said in a previous post, some cross over below 60 Hz (say 40Hz) and like to turn it up loud. So loud in fact that the standard drivers compress and the HP don't (or less so).

I asked this question before regarding the M80 HP and from Ian I got the response.
That he M80HP are mainly designed for 2.0 ch stereo enthusiasts who do not want a sub and that use at higher volumns. If, you are using a sub the benefit of upgrading from a M80v4 is Moot.
If you are not using a sub when listing to music or movies, then the M80 HP is benificial.

That said I realized that in movie watching I use a sub, as most everyone does. So, Getting the M80HP one could set thier Pre/Pro or reciever up to two settings. One for music 2.0 and one for movies 5.1, 7.1, 11.1 whatever. Cross over at 40hz with L/R and set the V180v4 to crossover at say 60hz. Your using a sub and as Ian said, it is moot.

That said I do not use my system at extreme volumes, I am ok listening occassionally around 90 - 95db. movies maybe 85 - 90db

These, M80v3 and vp180v3 handle that volumn extremely well I don't even think they break a sweat.
Actually, my current room is only 12x15x7.5 and I am scaling back to the M22's and dual subs.
I will wait until Axiom goes v5 before I upgrade the M80's to a HP, but those will be used in a second system for music only and at that it will be in a newer addition Movie room. 15x23x9
