HeY Ake, in about 2 weeks i'll have a 3 way designed and built by Rick Craig, Selah Audio, a member over at Madisound. Seas W22+Accuton C79+RT8P. I choose the Seas and Philips ,Rick choose the C79. He's using superior xover parts. So i should have them up and running and will post the review. Yes kits are a good alternative to the commercials, but for lack of time and more importantly the experience, i prefer to have a designer do the work.
