I have a pair of Snell Type C bought in the mid '80's and a pair of Large Advent Utilities purchased in the late '70s. Both have had new surrounds installed years ago, cones are still in good shape. They still pack a punch. I use a 400 wpc amp with high dynamic headroom on the Snell's.
How long should high quality speakers last?
My Zu Omen Def MKii (rev B) are going on 13-14 years old. The speakers sound wonderful. I have no intention of parting with them. The speakers came with the latest ZU tweeter design. How long should I expect the speakers to last without any issues? I do not abuse the speakers and run them with my Luxman 595ase amp.
