I have Maggie 1.7's actively crossed over to subs. HUGE difference getting the lows out of the Maggies. At $3500 you should be able to get the Maggie 3.7's with a full ribbon tweeter and a quality active crossover. After that you can add a pair of subs when funds accumulate. Rolling everything off at 60Hz with the 18db slope is nice however found 60Hz roll off on the low end at 18db/octave then the high end is set at 70Hz and 12db/octave
$3500 floor standing speakers used. What would be your choice ?
My speakers are 25 years old, working fine for now, but who knows I might have to replace them at some point in the future.
The amp would be VAC Avatar SE 60 watt/ch all tube with onboard phono stage. Nottingham Analogue Spacedeck/Spacearm turntable and couple of tape decks.
I am thinking Proac maybe or whatever.
