I've never been blown away by the Watt Puppies myself, though I've listened to them on numerous occasions because a local dealer kept wanting to sell me a pair. I've had excellent imaging before (Spica Angelus, Martin Logan CLS) and excellent highs (CLS and Energy Reference Connoisseurs) but the Maxx wrap it all up in one package and add clean powerful bass (3db down = 20 hz)
I think that there are many people that simply expect a certain boominess or over-hang in bass from anything with decent bottom end extension and the friends that have listened to the Maxx always comment that the bass happens....and then it stops and ins't there any more, like that was some sort of minto miracle, which I suppose with many speakers it is. I could probably do without Dave Wilson's approach of making speakers that are also fashion statements (mine are painted not in Ford Minivan silver, but in 2006 Ferrari Nurburgring Argento, a fact that probably added a couple of thousand to their original list price.
As a consumer, I find Richard Vandersteen's (old - have you seen the 7s?) approach - put all the money into design and components and then stick a big sock over it to keep the price reasonable.
Sitting here listening to Bach's Six Sonatas for violin and harpsichord on old RCA mono, those considerations kind of evaporate and what remains is the great sound. Pardon me while I flip the record......
