Okay, maybe this one should have been in the In Theory section, but I fully intend to build this project. The idea here is to chop the Tw6.1 in half and make a bookshelf speaker out of it. The idea was from Wayne J's Dayton Project. I'm in the process of building an entertainment center, and I want a really good set of bookshelf speakers. The Bk5.1's are doing a good job for now, but I prefer to listen to music without the sub, so I need something with a little more bottom end. In the Tw6.1 form, the Dayton 6-1/2's give a very solid bottom end down into the low 30's.
