    Have a pair of these that did not work out for my original project....

    To my ear, they are lacking a bit of "effortless" high end. Sorry for the subjective description.
    Has anyone paired them in a miniature two way with these, for instance...

    Still have not learned crossover software. Just checking to see if anyone else has info on a two way with the 3 1/2 Viva or could suggest a quick and easy crossover for the Dayton 5/8 or other in a sealed box.

    Thanks

    That would make for a very nice micro-monitor. Do not take the following as gospel, but rather as a starting point for experimenting. I would really go with a single, small coil on the woofer and a single, small cap and resistor on the tweeter. Let's just say 0.5mH, 3uF and 4ohm to start. Good time to learn how to tweak by ear.
    Don't listen to me - I have not sold any $150,000 speakers.

      Looks like it could be a cool combo. Or even the ND20FB in an MTM!

        The xover still works pretty good with +/- .010 change on the Z axis, so I would say this is pretty safe. Deeper bass can be had with a deeper ported cab.

          Very timely post. I just ordered 4 of the Vifas and a pair of the ND-20s. I was wondering how an MTM with this combo would work.

            I've been working on a design using that Vifa as the mids in a WWMTM tower.

              Cool thread. I also have a stash of these Vifa's, as I'm sure many PETT members do. And some spare ND20FB's. Following with interest.

                KINDA like mine.

                LP: I went with a 1.2mH series coil, and a 6uF shunt cap.

                HP: I went 3rd order w/an L-pad: 4uF series, 0.20mH shunt coil, 12uF cap, and "L": SR = 4 ohm, PR also 4 ohm.

                My vented box IS a bit larger, 0.34cf. A 1.5"d x 2" long vent will run fairly flat down to 60Hz, but with a 2w limit. The closed box can take about 6w, and (/but) therefore +4dB @ 200Hz, -2 @ 100, -6 @ 80, and -10dB down at 60 (compared to the vented box).

                  Thank you Jay for that excellent starting point, and everyone's encouragement here.

                  Mike, this may finally be a good time for me to try an mtm. With any more expensive drivers i'm generally too cheap to want to experiment much. But with the low cost value of these little drivers it's definitely an attractive idea. A press fit 5/8 tweeter between two 3 1/2 drivers seems about as close to coaxial as an mtm could get. Easy small cabinetry and good fit for my small home office room.

                  Chris,
                  "KINDA like mine."
                  Do you merely kinda like these? Or is your design 'kinda' like a version of the Vifa and Dayton with an implied smiley and question mark at the end?
                  Or is it the latter and i'm just a bit of an idiot?

                  Are they built and auditioned? Was it worth the effort?

                    Oh no. Never built 'em. My ratio of sims to builds is in the 10:1 to 100:1 range most likely.

                      So Cchris,
                      Is this for a TM or an MTM? And which of the tweeters did you sim this for? Thanks for adding your expertise. The sim you did for me for the TB W4-1720 ans RS28A works great.
                      Thanks again,
                      Mike

                        Now fantasizing about TMWW, small footprint floorstander. Maybe ND-105-4's (series) for the bottom, kinda like N-t-N, but with a mid.


                        W = 40=400, M = 400-4K, T = 4k +

                          A TM w/ND16.
