While I have the Excell drivers and Maestro power amp up for sale, I thought of continuing the little project I started when Zeabre was looking for white speakers.
The history: I promised Zeabre to build a set of speakers for him to see and hear what is possible with DIY. Just a quick test build, with what I had available with me. Had he waited just a little longer before he decided to keep his Spendors, would the project been completed long time ago.
Anyway, I'm kind of glad I didn't Finnish it sooner, since I spend quite some time on the x-over. Its not a setup that I intend to keep, but till someone decide they want to buy the drivers I might just as well keep playing.
Its probably the first time that I'm done a sealed enclosure with quality drivers. Usually I would go for sealed with very cheap drivers that I'm too lazy to test the TS parameters.
I used the W18e001 and the Millennium tweeter with a 4th order acoustic x-over at 1800Hz. So far: boy oh boy, I have never realised that a proper driver in a sealed box can sound so natural. I've listened on them in my sound room, that is somewhat acoustically treated. Its only 3.5m x 3.4m. And I sat about 1.5m from the speakers.
Compared to the Chario's I owned (A R20k speaker set), its way more natural. And don't get me wrong, the Chario's were good.
With Jenifer Warnes - Way Down Deep, it sounds as if it run out of breath (power wise) long before the Charios ever did, but that could also be the cheap little amp I'm driving them with that doesn't have big enough caps on the PSU. Bass is however deep. I think a factor very often forgotten with speaker design is the room gain below 100Hz, which increase the usable low frequency responce to more than what simulation shows.
My son played some Accopolyticas songs, and the Cello sounded just so cool. Very very natural.
Now I can't wait to put a propper amp and preamp on them to hear what they really sound like.
