Minimonitors

Also look at Reynaud Bliss Jubilee at half your max budget new and less used.  Have owned multiple Reynaud monitors over the years and now the Fritz Carrera Be.

@bananaslug have you considered the Dynaudio Special Forty ?
They're know to

...put out what its fed, play well, and basically disappear

Combined with a sub of your choice you can easily stay under $5K


@ditusa I'm afraid you're incorrect.

minimonitors minisound ALL minimonitors are cutoff @70hz try a pair jbl 4425 monitors I run the jbl with quick silver amps same power as the vac amp cut off @ 40hz

Most mini monitors go well below 70hz. I've measured them myself and found even the affordable Paradigm 20 studio monitors go down to 32hz. Granted they may be down 6db or so at that frequency it's still audible and they were flat to 48hz. My Revel and B&W stand mount/monitors easily do the same. 

The OP's VAC Renaissance 70-70 specs pretty good for low frequencies.
Power Output:
65 watts continuous average power at 1 kHz with less than 2% THD into 4 ohms connected to the 4-8 ohm tap

Distortion:
0.12 % THD at 10 watts 

Frequency Response:
down 0.5 dB at 6 Hz and 90 kHz, ref 0 dB = 1 watt @ 1 kHz
down 3.0 dB at 2 Hz and 103 kHz, ref 0 dB = 1 watt @ 1 kHz

Power Bandwidth:
down 0.5 dB at 12 Hz and 58 kHz
down 3.0 dB at 8 Hz and 85 kHz

Another great option I meant to mention is the Vandersteen VLR CT.

I'm waiting to audition a pair of these and may just buy a pair without an audition. Trusting my experience with Vandersteen speakers I'm sure they're outstanding.

Would recommend looking at Raidho XT-1
they are incredible speakers and a bargain. They compete with speakers costing 3 to 5X their price. Andy

Vandersteen 1ci.Small footprint and no need for a stand except the one that tilts them back.Good bass and spacious highs for about 1.5 K.
