    Looks pretty cool! I envision a lot of great projects with these. My first thought is a soundbar application.
    ​I was thinking "center channel", e.g. coax 4" at the center, flanked by two 6.5s to handle the lower bass duties.

        Very nice! I wish they made a midrange coaxial version of this. One big problem with a 2 way coaxial is that the large woofer excursion for reproducing bass will audibly modulate the treble response. Therefore to really get the benefit of a coaxial, a 3 way should be the minimum.

          Sorry Allen, not until a practical demonstration.

            I'm thinking the same thing, but obviously it will depend on the frequency response data once PE supplies it.

              I like that idea too. Right now I'm leaning toward 3 of the 5.25s for an LCR. Quick model shows favorable results with .375 cubes each.

                The Daytons remind me of the Rockford Fosgate R1675X2 pair I used in my car. I tested them in cardboard box enclosures in the house before installing them in the car, they sounded quite nice (6x9 in the same series sounded a bit harsh in the lower treble though).

                  And what would be the main design use for these do you think? Surround sound speakers I'm guessing, and at least for the little 4" ones, probably smaller boom box type, or all-in-one bluetooth amp setups for the kitchen or bedroom.

                  I think these could be the basis for a decent little table radio setup if you don't mind having a little more height.... I've been thinking about doing a nice table radio with a Voxel-type sub hidden (or at least camouflaged) up on top of the wall cabinets.

                  At any rate, it's nice to see these; they're something new and different.

                  Interesting question on the Z - it may not be what you expect. Here's a graph from a coincident design I just finished.

                    My two arrived today. Waiting on the Dayton frequency files to be posted as well.

                      Spec sheets are being built as we speak, expect them sometime next week.

                        I'm thinking of the idea of a center channel that uses the 4" coax flanked by two ND105-8 for bass duties for a very slim center channel.
                        Or the 5" coax paired with 6" woofers as someone else mentioned.

                          I haven't done anything with the 4" yet, but you might be surprised with the bass response you will get from the 5". I had them in pretty big cabs though, so it really depends on your output needs.

                            My quickie modeling of the 5" suggests about .5 cubes with an fb of 50ish. Even in .38, it looks very good to about 60.

                              I tried them in 0.5 cubes and got similar numbers. They looked a little odd for a bookshelf in that volume but a small tower would suffice.

                                I think the biggest issue with a single 5" coax for a center channel is that it just wont have the sensitivity / output for really clear dialog near reference levels. (esp when baffle-step is considered)
