Brilliant tweeter

Ordered and delivered as advised and well packed. The tweeters are replacements for vintage Scan Speak d3808 tweeters bought in 1972, done well didn't they. The SB tweeters fitted the cabinets with out any mods, just a minor tweek on the cross over .
These are working just fine and are revealing micro detail I had not heard, triangle really sparkle with a really fast attack. Drum kits really are very crisp with good detail. Not yet fully used these but so far results are really pleasing. These are teamed with Seas w18E001-08 bass drivers in 1.2cu/ft cabinets tuned at 34Hz driven by a 70watt state of art amp and a Roksan Black cd player.

Thanks for the comprehensive review David !
