Used the supplied way, the big Maggies are just as you describe Darren. Hifi dave meant that "too much" was perfect
Jimmy always wanted to go that much further, for good or ill, so the first thing he did was to remove the grille cloth, turn the speakers round so the sound came from the rear (magnets were then behind the diaphragm rather than in front of) and maybe did some crossover tinkering (I can't remember). The end result was a hugely OTT sound that could be fatiguing on bad recordings/mastering - a similar kind of thing to using high resolution huge monitors at home (large double-driver Tannoys, JBL's, ATC200/300's, that kind of thing). The Impulse speakers he ended up with had just the right balance of detail, dynamic range, lowish colouration and listening "comfort" too.
Tear down these walls; Cut the ties that held me
Crying out at the top of my voice; Tell me now if you can hear me
