Very good sounding speaker set. It’s still original and beautiful looking. Read the positive online reviews about the sound. This closed system has tight but warm bass and beautiful mid-hi. I like it better than B&W like opponents. All in excellent condition, also the fronts. Foam from woofers is as new too. The unusual inverted drive unit geometry, first designed by Henry Azima in the Mission 700, goes some way towards equalising the distance from the acoustic centres of the drive units to the ears of the normally seated listener.
