My home built 4 pi speakers - Wayne Parham's design. Playing Mark Knoffler Shangrila album

My home built 4 pi speakers - Wayne Parham's design. Playing Mark Knoffler Shangrila album Tube. Duration : 1.87 Mins.


These are the 4 pi speakers I recently built. They still need to be finished. They are Wayne Parham's uniform directivity design (www.pispeakers.com). Wayne has been unbelievably helpful with his advice. The high frequency driver is 1" throat B&C DE250 mounted on Eminence H290 horn , mid woofer is 15" JBL 2226H. I bought the drivers from parts express and crossovers from Mr. Parham and the wood panels cut to spec by the helpful guys at home depot. The midrange reproduction is fantastic. Voices sound spectacular! These speakers can reproduce the air and ambiance in a concert hall or venue if it is in the recording. Eg: BVSC at Carnegie Hall. Superb dynamics too. Therefore great for 2ch HT. I am driving these with a tube integrated amp with Russian made tung sol 6550 ~ 30 watts / ch.
