Default Push Pull, Dipole or Ripole...

A great thread topic... choice for pairing speakers with particular "requirements"

I ran with an *Audio Pro B270 active sub for ~15 years on Quad ESL57 (ESL63 and LS3/5a) It was utterly seamless, with a great sense of speed, incredible dynamics and slam with dual 8" push pull drivers. I will forever be a PUSH PULL SUB WOOFER fan. *the B270's sensitivity and drive level matched these speakers well, it got out of the way of the music.

I wished that I never sold B270, would like to build one like it ~ or ~ possibly build one of GR Research *dipole* Push Pull Servo driven sub(s?) But I want to use my own amplifiers on subs. **for use on ESL57 or MG3.5r.

The RIPOLE sub as mentioned [by JohnnoG] above is pretty amazing / has held my attention for many years. *I thought* that I read it was more of a spatial / "ethereal" type of bass, not one that is known for slam or pressurizing the room... [I am curious about consensus here]

I already have multiple monster (>500 wpc MOSFET) amps built, 2 and 3 way electronic crossovers... subwoofers are next on my list...

Push-pull is really only useful with “cheap” woofers. The configuation is often seen with OB woofers that have even numbers of drivers each side.

I get it, am with you on this point. 100%


*I also like push pull, where one voice coil is always in the magnetic field,
with linear impedance / drive... when used with "modest' power amplifiers.
as portion to the budget driven basis common to DIY efforts.


I replaced my ESL63 / B270 with something *better*
used during the late 80s and 90s

Revel Ultima Studio [admittedly, love at first sight]
then added the Sub 30 Subwoofer *sort of overkill
from 2000 - 2015 *my Audio Mart ad.

~ I am driven to "OUT DO" what is shown ~
working in the DIY build world...

Sub woofer for Quad ESL 57s with active crossover
Based on considerable experience....

I'd say only add bass if you are adding treble too,

there's no false localization on music with a XO at 130 Hz to a sub, if slope is sharp and low distortion - that will let you play Quads louder; likewise adding a tweeter might do the same by removing the need to drive high freq with the ESL amp, given the load ESLs present to amps at frequency extremes,

I never thought there was much "matching" of speakers, but a Klipshorn bass will fill the air in the whole room with clean full bass kind of resembling ESL sound.

I agree. That is the only way you will achieve a seamless blend with your panels.
