We have the passive version, the 4367 arriving here as soon as they are released in the UK,
hopefully next month.
With the M2 you either need the JBL/Crown amps or I believe the spec-d box, which will implement the crossovers.
I did look at the M2 but it just appeared too much kerfuffle, also JBL's UK pricing is all over the shop, check out the M2's price via their 'domestic' and 'pro audio' distributors!
