Last iteration on them was re-voicing the LE85/Smith combo, lowering the lowest frequency output. After that iteration there was no longer any need for the 077. The process ended with charge coupling the network.
Lately I have also moved them away from the back wall and raised them up from the floor, giving a much better bass frequency linearity.
IMO the sound is very good and IME you chicken out before they do. Playing on them is simply fun and addictive.
I have only 2 concerns with them. The first being that all drivers are in one box. The second concern is impulse response - which is not spot on through the frequency spectrum. I.e. the bass comes little later than the rest.
The boxes have a footprint of 55x55cm, are 125cm high and the top is 55x50 cm. The dog box volume is ~30l, which in retrospect is unnecesary large.
The above measurements of the new horn is with TAD TM1201, not the 2202A. Judging by a short session running this driver/horn combo, the TAD driver is ridiculously good.
