1.do you buy the pmc?
2.can you use the Ashly in home audio?

Hi John. I'm John also.

The SS tweeter is grossly overpriced IMO. The ATC mid is definitely not worth that much money.
Do you have any speaker building experience? Good drivers are wasted in poorly executed designs.
The 10" refered to, are they RCF? The L10/750YK?

IMHO, No. (well maybe if you think that the extreme Danish School speakers are good -- i find them boring & lifeless)

Other John has a good point... if you haven't diyed a speaker before, start with something more modest.

I would always chose to build my own, rather than buy ready made.
What are the specs for the RCF? A true midbass really doesn't need a midrange driver (these are on the big side at 10").

[planet10]

There are lots of guys here repurposing pro gear to home hifi -- often in the form of a big midbass, XOed over to a 500-1000 Hz horn (with optional supertweeter.

Because of the efficiency differences, active between midbass & horn is usually recommended. Also note that given the efficiencies, and how much less level these kinds of systems need in a domestic environment, they can be brutal at revealing the deficiencies of most big SS amps in the crossover region. This may be an opportunity to get a smaller Class A amp (tube or SS) for the high range (the Bryston makes a great sub amp, they are on the better end of big SS, but still may get revealed if used for midbass -- only one way to find out)

Here is a thread i have been following sporadically that seems to have turned into a discussion of these kinds of systems What's your pick for drivers in an ultimate 3-way (for music)?

It's a good job you live over the pond, as you're cruisin' for a bruisin'!

my google turned up that these went for about 6k canadian new.4200.oo for them when their 6 years old sounds alittle much to me.plus only 250 hours in 6 years.who spends that knid of money on speakers to use them 42 hours a year.sounds alittle fishy to me.
but if its costing you 3k in drivers to build+plus time and money on cabinets,i would try to talk him down in price and save alot of work

Sorry Al. I'm not bashing ATC, that might be an amazing mid. But $840.00?? way too much.
