Axiom Home Page Forums General Discussion Technical Questions Impedance graphs for bi-amped M80V2 ?

Hi,

i'm perilously close to bi-amping my M80v2s

has Axiom plotted impedance curves for bi-amped M80 V2s?

my first guess is that the impedance would increase because fewer speakers are being driven, but could really use some help in establishing even an overall number.

thanks in advance,

Elden

Here is the graph for the M80s.

Hi, Rick.

Thanks for the quick reply.

is this for the bi-amp configuration? i'm guessing one would see 2 curves: 1 each for both speaker circuits.

thanks,

Elden

No it isn't. How exactly are you planning on biamping the 80s? If you are doing a passive biamp I don't believe the impedence will change.

Elden, unless you're planning to use a separate external crossover before the amplifiers(and entirely separate amplifiers)and remove or bypass the M80 crossovers, nothing significant would be accomplished. On the impedance question, the separate low and high frequency sections of a speaker have the same impedance and, as Rick commented, passive biamping doesn't change this.

No, Axiom doesn't have bi-amped graphs available, and Alan has made clear that the process isn't considered to be worthwhile. The presence of two sets of input terminals is essentially a concession to marketing considerations rather than reflecting principles of audio technology.

I like pictures. Wow, I wonder why the change in peak around 1K, compared to the flatter ti chart Wid posted?

Alan, or someone else from Axiom, can you coment on which graph is accurate for the v2's? Thanks Randy

The question was actully for something I'm testing with my Emotiva MPS-1 amps, sorry for the confusion.
