Ok, I pulled all 5 speakers. The two out ones measured 6.0 ohms (left) and 5.4 ohms (right). The three 5.25" ones were ALL open circuit! So where can I get replacement ones? Does Axiom sell them (not sure if they are component sellers or finished products only)?

Or can I replace them with any 6ohm 5.25" speakers? I don't want junk but as you might have been able to tell, I'm no expert either.

Thanks again.

Axiom will sell them. They're relatively expensive (something like $60-70 each, I think?) but they'll work much better than third party replacements. I strongly recommend that you call Axiom before you proceed with any part replacements.

if you buy "matching" replacement speakers from another mfg.
you will lose most of the quality reproduction you should expect from your Axioms.
there are many other things than size and impedance that are much more important in a speaker design.

I think I'd go for the upgrade model myself before spending around $200 plus shipping for 3 repacement speakers. New VP150 v3 is $434, or $391 on the Auction site (buy it now price). Sure it'll cost twice as much, but you've warded off any potential expensive problems for another 5 years. (Did that make any sense?)

Not to mention a misdiagnosis.

Yes, if the replacement speakers are each 60-70 (180-210) then it's worth considering a new VP150. However, I also have a pair of M22's and QS8's of the same vintage as my current VP150. If I mix a new VP150 v3 with the other speakers, will there be any noticable difference?

I guess I'm asking what is different between the original VP150 and the newer v3 speaker? How much of an improvement has there been in the last 8-10 years?

Personally, I doubt that there would be "that much of" a noticable difference. If anything, I think there would be an overall improvement in sound quality. Then if and when you decide to replace the M22s (if that should ever happen), you would already be one step ahead with the newer VP150.

Ken,

Just curious, how could I misdiagnose? I removed all 5 speakers from the VP150. I tested the two high range speakers, one was 6.0 ohms and the other was 5.5 ohms, so they checked out as expected.

WIthout changing any settings on the DMM, I repeated the exact same testing procedure with the three 5.25" woofers. Presumably, all 3 should have read about 6 ohms, but all 3 were open circuit...

By open circuit, do you mean that it read Zero ohms?

If that's the case, then perhaps the real problem is the cross-over, feeding too much current to the speakers(???), causing them to go out. Just thinking out loud.

CatBrat,

Nope, zero ohm would be a short circuit.

This read off the scale (on my DMM a 1 is displayed in the left hand corner, not the right side as if it were 1 ohm). I slid from the 200 ohm range up to the 20M range, each one stayed the same so I'm certain it's reading open circuit on all 3.
