Altec 420 questions.

I know this is an old thread but maybe there is still interest on the Santana/420A driver. I picked up a set of the 420A drivers on the cheap a few years ago and finally put them in a pair of 828 cabinets. Like others on this thread, I tried them with different tweeters such as JBL 2404H, EV T350s etc. I used an EV Merlin ISP-100 crossover to best match the tweeters to the 420A/828 combo. The sound that yield the most phenomenal results was putting a 1000Hz LeCleach horn on top of them with a TAD2001 driver. Crossing over them at 3300Hz with a third order butter worth filter, the voices sound absolutely real. Myself and people that have heard this combo are amazed my the quality. I know this is an overkill, so this weekend, I am swapping the TAD out for cheaper drivers (ex. 902-8B) to see if I can get similar results.

Awhile back there was a gentleman on ebay selling an quasi A7 system using 420A woofers in a 825 cabinet, 511B horns with JBL drivers and ESS tweeters. He was asking very high price for the combo....but maybe he was onto something..

Correction, I think he had 1005 horns instead of the 511....

I've always liked the sound of the BiFlex speakers. The vocals really come out.
