    Re: RS180P-8 and RS28F

    Pete , that sim and curves were not the final crossover but very close to it, my post with the off axis curves was though . these are designed to be on wall surrounds witch did present some challenges . as far as distortion , i posted a near-field (2" off the plug) shot that showed 3rd order . i'll have to go back through my files to see if i kept more . i also just moved and haven't had time to set up testing gear yet but i'm getting ready for a pro-driver 3way and when i get set up would be glad to run some more distortion sweeps ....

    post # 67 is final XO and # 25 shows 3rd order ...

          was hoping to get these painted this week as my buddy is going to be spraying a Nissan truck with dark metallic charcoal . BUT upon inspecting them the primer has had a adverse effect . all the bondo'ed seems have shrunk and are visible and it appears to have stressed my 1" baffle to the point of cracking it just before it rounds over ...

            looks pretty sweet. wish i saw this thread before. I've gone the same woofer with the peerless tweeter, fingers crossed they turn out like yours.

              I didn't realize the bondo would shrink - perhaps the MDF (or ply) did instead of the bondo? Either way, tough break!

                thats what i'm starting think , the mdf swelled . those seems were bondo'ed twice and blocked smooth . they sat unfinished in a climate controlled room for almost 4 years and the two weeks they were at the shop it rained all day every day . not to mention the high humidity that we have anyway in FL .

                  Yeah that might do it - hopefully an easy fix and ready for paint soon

                    plan going forward is to wait until the day they're going to be painted and i'll skim coat and sand all the seems one more time . then prime , sand and paint . this morning i injected super glue into the crack to bond it together . tonight i'll sand that then inject some TitebondII into it.
