Wanted to share some pics of my newly completed SB 3 Way Classic build. Speaker is very detailed with exceptional bass qualities. I have also built your Seas 5" and am still using them. As always thank you for all you do for the DIY speaker building community. My system consist of the Yamaha A-S2200 integrated amd, matching Yamaha CD-S2100 CD-SACD player and Rega P2 vinyl spinner.
I have a question. What is the next level up from the 3 way classic in terms of performance in your opinion. Not looking for sound characteristics, just performance level.  
Also what about a Tannoy based design along the lines of the Arden or Cheviot. Some sorta dual concentric design. Always had a thing for the big Tannoy's. Just cannot afford them.
Please feel free to post anything here. Thanks.
