New OB bookshelf ideas

Looks very good. The dual 12's per channel are definitely a good approach.

How are you liking the top end on the B3S's?

Right now that is the weakness in the system. The B3S has an adequate top end, but it isn't great. I've been noodling around with the idea of adding a dipole tweeter like in the Linkwitz Orion ++ using two Dayton ND-17FA's per speaker. I'd use a 2LR crossover at 4,500 Hz. Right now that's a project for the next parts order after I finish my wife's X-mas present!

Yeah, I must really dream about Linkwitz products. First, playing around with scrap materials I make a pseduo Pluto. Now I'm adding dipole tweeters to my 3-way open baffle speakers. Wiring isn't done - should be ready in a day or two.

Wiring is done - FR to follow.

I heard these in person yesterday and they sound great. Very open, airy, and mellow at the same time. They're so good that Boomie is starting to hear why mp3s stink

Well, I knew MP3's stunk before. These speakers do make the difference much larger. Also I'm noticing the differences between good and bad recordings on CDs. Now there is a whole new host of things I'm unhappy with.

Here is a quick FR from my listening position. The big spikes and nulls are the room - you can only treat the top of a Cape Cod so much.
