I'd kind of like to replace my IWOW VP100 for an IWON VP150 to see if I'd like it any better. I know a VP180 would be too much for my needs right now.

Micah, when two speakers are run in parallel the resulting impedance is such that its reciprocal is the sum of the reciprocals of the impedances of the two speakers. Using 6 and 4 ohms, this works out to 1/6+1/4=1/X, 2/12+3/12=1/X, 5/12=1/X, 5X=12, X=2.4ohms.

Keep in mind that the nominal impedance ratings of speakers don't represent their impedance over their entire range(the 4ohm rating on the M80s is a notable example)and that 2.4ohm result would only apply at a frequency where the speaker impedances were in fact 6 and 4 ohms. Also note that a low impedance doesn't necessarily cause a problem if the power used at the low impedance frequency wasn't high enough to require an excessively high current.

I've wired car subs in series/parallel, could this be done with the VP180 and the VP150?

Micah, i have Krell amps and I am not sure if i want to run those 2 speakers in parallel.. I don't think that there are any recievers that could power a pv150- and vp180 in parallel safely.. If you have a power amp you might be able to get away with it, but you will need a pretty strong amp... my amp's are rated at 250W at 8ohms, and 500W at 4 ohms.. and if i put a 2 ohm load they would be making 1000W, but Krell has not designed them to be stable at 2 ohms though, so i don't know that i want to push them....

not with only 1 set of terminals wild, to get a series connection you would have to have 2 sets of terminals. one in and one out, if you will... when you wire a sub in series, you use one set of connections, then on the other side of the speaker you use another wire to a different speakers. making the current go though the first speaker, then to the second one... there is no way of doing that with the way the cabinets are designed from axiom that i am aware of.

Give Axiom a call, Cat. I'm sure you could try out the 150, if you prefer it you could probably trade up, or if not, send it back under the 30 days return policy. Check with Peter Bell, maybe.

Rick, I assume that you're referring to two subs in parallel plus one or more in series with them. That wouldn't apply to just two speakers.

Yeah, that's probably the only way. I'm going to have to wait until I have some spare cash though. I've got too many projects going on right now with the house. Needing a new dishwasher and new floors, etc.

Haven't posted in ages but if these dimensions are correct for the 180 then I have no idea where I could put this monster in my setup:

Dimens. H W D (inches) 39.5" x 9.25" x 17"

It has to sit on my stand in front of the TV and I have my amps, Belkin pf60 and satellite receiver behind the vp150. At 17" deep there's no way anything else will fit there!!!

This thing is crazy big!!!
