      I used a Morel CAM558 as the mid with a NeoCD1.0 ribbon. The two really work great together crossed right around 4k. Then you just need a woofer that can cross smoothly around 900 Hz. I used the Usher 8945A. It is my best sounding design to date.

        good info .... i have all the parts on hand for that sim and a box with a detachable baffle that would fit the RS225 all ready to go . i may just put this together this weekend and see . Craig , did you ever use you famous maker 3" ? i believe you said in a mtm . if so what did you think ?

            DUDE !!!! that looks awesome !

            maybe one day after i get the electro-magnetic aspect of this all i'm gonna have to spend some time learning woodworking !

            this weekend i'm gonna put this together re-purposing my CC prototype box . just need to cut a baffle and cutout the mtm chamber ...

              Thanks! Trust me though they only look decent from 10 feet or more away

              Are you sticking with that new cc you were working on and building a new box (since you said you are repurposing it) or changing the design?

                  wasn't happy with the impedance in that 1st sim . i think this looks much better . what y'all think ?

                    Impedance looks phenomenal, definitely better than anything I’ve ever done, especially in a 3-way. Any chance you can drop that 900 hz peak down a dB or two or 2k up a touch to offset that bump and still keep the nice impedance phase?

                      was working on that and i'm guessing a lil filter peaking as it's rite at cross . small changes there in FR get the impedance wonky . this is where i'm at now ...

                        btw , these are PE factory files for the RS225 and DS90 and traced factory for the Neo . i can attach the Neo file if anyone wants to play along .

                          I did get the MTM enclosures built using Peerless BC25SC06-04 tweeters. Unfortunately I got side tracked with other bigger projects so they are still sitting here unmeasured :( Maybe I'll set them up and get a good set of measurements this winter.

                              thanks .... looks like some tweaks in the tweeter caps help to flatten out that 3-5k hump but at the sake the of impedance curve . not bad at all though . definitely gives me directions to go with .
