You are wrong there....you can get huge (more so), powerful (more so), and beautiful (more so) with modern Tannoys....you need the right ones. I can see someone feeling the tulip waveguide is not as beautiful, but the traditional type new Tannoys with the Alnico magnets and pepperpot waveguides will do all the old ones do, plus some. You'll pay more than for the old ones to get those advantages, so that is a negative. But they are still reasonable in price compared to what passes for state of the art in modern speakers.....and most are nothing near the performance.
Best vintage Tannoy for rock?
I know that Tannoy speakers are not usually associated with rock but I'm mesmerized by the sound of old Tannoy 15 monitors (Super Red, Gold, Classic etc) in big cabinets. The sound is huge and beautiful - you just don't get anything like that from the modern Tannoys. So what's the best vintage Tannoy speaker to rock out with deep bass and tons of punch? I'll be using Manley 250 monos.
