I love my 436's also...However the things get awful hot though...one of mine will go into thermal protection if I really get the system going. There is suppossed to be a fix for this that the dealer can do but I don't trust my dealer to do it. so I'd have to send it to Madrigal to get done & I just haven't had the time to do it. I think its some kind of modification to the fan or something...anyone know about this? Also, how has your follow up been with you dealer after you bought your equipment? Mine stinks,
they never know about updates or anything. I've purchased quite a bit of Madrigal gear from my dealer including the 436's a No.40 & revel speakers...
