Speakers for string Quartets

No one mentioned time coherence. Quads got me interested in coherent speakers more than ½c ago.

Vandersteens are pretty good. Maggies can be if set up properly. Spice TC-50 on stands with sub in a good room can transport you.

Tri-amped, time corrected Eminent Tech LFT-8b w dual subs are outstanding! 😉

With 650 wpc, they will make you duck in the finale of the 1812 or have you stomping along with Queen’s "We Will Rock You". Jaqueline du Pre and YoYo Ma live  here!

Small string ensembles in a good room are extremely rich in coherent harmonics.

Speakers plastered on a flat plate are never going to cut it.

Quad 57's with the right room set up and proper amps matched to them

Quad 2805's again, with proper amps matched to them.  

the 2805's perform well down to about 33hz

Quad 2905s.  more speaker area.  more bass response.  2905s perform well down to about 28hz... again with proper room set up and amps.  

Magnepan's: several great options.  I used Maggies for over 30 years.  I like the 1.7s, the 3 series... and hot rodded Tympani's.  Maggies need a bit more power than the Quads.  and again proper room set up and proper amps matched to them.

I am not a big fan of the ML's. the ML's are nice.  really good in fact.  I personally don't care for the bass range being driven by a cone speaker and trying to match that with the planar mid range / treble via a cross over.  Again very good.  But for what you are specifically looking for.... 

nothing will come close to the Quads.  Seriously.  NOTE: I have not tried Quads with any of the amps you list.  I drove my 2805's with AirTight ATM-3 mono blocs... sublime!!!!  

I know several amazing violin and cello players.  some are world famous.  I am familiar with standing near them while they play live.  I know the sound and the feeling in my bones from strings being played,  I have been actually in the recording studio with some famous violinists and know the sound WELL.  The Quads are stunning close.  Especially when set up properly.

The Maggies are quite nice as well.  I just prefer the Quads.. they are amazing.

IMHO  

fascinating read,

Re tonality of speakers Im amazed to hear strong recommedations for Vanderteen.

My limited experience of that touted brand was entirely negative,

One of our respected audio store here in Toronto was offerin a record cleanibg service for LPS back in the day.

About 10lps having been cleaned and dried he played one back on the house demo system-the speakers being Vandersteen Towers.

Well the lps were cerainly cleaned up but the sound was brutal.

Id assume this upscale shop wdve had the speakers properly set up in their listening room and paired with sympathetic electronics but granted the reputation of the brand very likely not.

At any rate my experience and that long ago.

Most posters are blasting past the amplifiers you have.  You would need to decide between the lower powered ones and higher power.  Most recommend choosing a speaker and then getting the right amp to power it.  For timbral purity with lower powered amps, such as you mainly have, I'm going to repeat my recommendation of Audio Note.  I was at Deja Vu in Washington DC and put on my favorite CD of English viol consort music (the antecedent of the string quartet) and I was blown away.  

Consider a single driver speaker that is not a horn, e.g., Voxativ. This German speaker uses the cabinetry to drive bass notes, like a piano. It is acoustically designed using many of the principles of high end piano design.. Vox’s are high efficiency, very fast, and not cheap. I run my pair with a 300B SET.
