Ahan,
Seeing the gorgeous grills of the Patrician IV's tells me that, if you bought them new, you and I must both be on medicare. I first heard them at Audio Engineers in West Allis Wisconsin in 1957. They had 2 Patricians, and a JBL Ranger Paragon. When I heard them there was a special price on Patricians; buy one at $999.99 and get the second for a penny.-----
Being in High school , I built two of them over the next 2 years. It would have been cheaper to just buy 2 for $1,000.
I used them until 1984. I heard an infinity Quantum Line Source, used, and the first generation of the IRS. Sonic preferences changed, but I still have all the drivers and crossovers from the Patricians. I'll keep them along with the memories of my first girl friend.
Time allignment will enhance the sound of one of the greatest speakers anyone could hear, good luck.
Ken
