The '57 have a bass bump around 90Hz, and output falls off quite quickly after that -
having a crossover at 100Hz - or 150Hz if you prefer- removes this signal from the quad, leaving you with signal that the quad operating where it can work its magic- The sub can pick up the bass duties
The '63s have a very different construction for the panels from the '57s - I'll stick with the '57s-
I have no experience with the 2xxx series Quads ...
Happy Listening

Speaker resonance, if working to spec., should be around 65-70Hz. 90Hz tells me the film in the bass panel has gotten old and brittle raising resonance. If the panels are rebuilt the rebuilder used too much tension on the film.
Of course there is little bass below 40Hz and the region between 40-80Hz can have a rather one note quality but it is still quite tuneful and musically pleasing.
Agreed, the bass of the 57 has been found to be a little "wooly" to some owners. Not just rolled off in the deepest bass, but not very clean in the second octave (40Hz-80Hz). Removing that frequency range by installing a simple, single-capacitor high-pass filter---rather than an active electronic x/o, and adding a pair of really good subs for the bottom two octaves, and you now have a speaker capable of playing a little louder AND cleaner. This has been done for decades with great success by many Quad 57 owners.
For those preferring the 988 and 2805 Quads (instead of the 989 and 2905), the money saved by getting the cheaper, extra bass panel-less version will pay for the subs! More bass, deeper bass, and, more importantly, better bass, and the Quad itself will sound better when relieved of having to reproduce that low bass, the upper eight octaves now being more distortion-free.
I agree with you guys but I have the high pass filtering through the digital crossover.
The next thing I'm under consideration is DBX Venue 360 and which has multiple analog outputs along with other features for flexibility while dealing with/complicated setup(e the ESL.
Exactly. If one wishes more bottom to the Quad the smaller one with subs will produce a much better result that the larger version without subs.
The downside of this approach is system complexity. Some people will opt for the larger version just to keep things simple.
The bass is quite nice with the 63 type speaker. Not the last word of course but very good, perfectly integrated and musically pleasing which is the most important thing so I don't have any real desire for subs.
When I want my bass fix I just listen to Sound Labs. They have the best bass performance of any loudspeaker I have ever heard. They have great extension , are perfect in pitch something lacking in in the bass performance of most speakers, and they have bloom in the bass, again something lacking in the bass performance of most speakers. It is this bass 'bloom' that I find most enchanting. This is what it sounds like in the hall.
As incredible as the bass is with the Sound Lab there are some owners that are bass junkies still want more and add subs. Amazing.
