Hi, I was looking to buy McIntosh amp. MA 2275 and I happen to see and hear the XRT-28 made by McIntosh. I had hear many speakers before but I was really extremely impress (blown away by this arrays - if you can call it that. I'm new to line arrays but this are not typical looking arrays. Instead of one row of drivers per speaker they have (20) 4" midrange in 2 rows (10 each row) with (16) - 1" tweeters in between the Midranges and (2) 10" Woofers. I find out from MC web side this are 3-way sealed system in aluminum enclosure - and yes the price tag 18K !!!! They sound is absolutely spectacular (only my humble opinion) Dos anyone think it would be possible to DIY similar project ? Obviously it wouldn't be aluminum enclosure and different drivers. I understand the quality and precision of the finish speakers wouldn't be the same but I'm sure it could be done for a lot less then 18K Please let me know what you guys think - Am I out of my mind ? Did I really lost my marbles ? John
