Way back when B&O used Celestion Drivers in a number of their speaker systems. The 5700, 5702 and M70 come to mind. I used 8 of the HF drivers from the 5702 as super tweeters to add frequencies above 11,000 hz to My Bozak Concert Grands. My Symphonies have 2 each. The Grands are tri-amped with a separate amp for the Celestion super tweeters using a UREI crossover at 12 db/octave. The Symphonies are bi-amped and I use a 12/db per octave passive crossover for the Celestion super tweeters. I could have used Vifa tweeters, but once I started with the Celestion, I have stuck with them. The last time I saw a pair of the tweeters on E-bay they sold for $200.00/ I paid $32,00 way back in the early 70's as I remember. The B&O rep was a great guy and got me 8 pairs tweeters at the time. When we sold our Casavant pipe organ to the Baptist church in town, it was up graded with Resonant speakers in the bacK of the sanctuary. They used Multiple Celestion speakers with a 10 inch woofers and multiple tweeter speakers. They also used more and different Celestion speakers to supplement the pipes up front. I was amazed how well the electronic and pipe organ blended together. The company that put it all together was from Britain as I remember.
I installed and maintained many discos in Old Mexico and ran across any number of Celestion Music speakers being used. They didn't hold up well as the tweeters were under rated as compared to the mids and 15 inch woofers.
I ve only heard Celestion speakers at trade shows and at Listen-up hifi store in Denver. They had great highs, mids, but the bass like most European speakers seemed limited to me. Not a bad thing, just not my choice.
