I'm glad you found a solution. Its not ideal, but is does allow you to set up the speakers the way you wanted and enjoy them.

I wonder if Axiom is going to put something in place to avoid this issue in the future. Something simple like threading a spike into each hole a couple of turns at the end of line to verify all inserts are threaded. Thats the kind of thing we do in automotive manufacturing all the time.

If Axiom really believes that bi-amping is a myth, and can't be accomplished with the passive crossovers in place, why do they still build the M80 with two sets of posts? Well, they've stepped up, and now if you want the placebo posts, you have to specially request them, and wait 10 days. Though there's no additional cost.

So if you had bought some Paradigm's would you be expecting the same part replacement ability from them?

I do agree the prices seem/are high and wonder if Axiom has considered special pricing for a full kit(2 speakers), ie 4 5.25 drivers, 2 tweeters and 2 crossover for M22, opposed to individual component pricing.

I do not know if Paradigm ever offer any upgrade, but if you decided to do it, IMO it is nothing special to expect that you will be realistic with the prices, specially with your previous customers, otherwise just say no and period, nobody expected nor forced Axiom to offer any upgrade, we just asked them if they would like to offer it...And please do not bring Paradigm here, their performance is not in the same league, and their policies and prices shouldn't be in the same league neither...
