Ok that is more impressive than I thought, very smooth distortion profile. I bet it sounds pretty dang good. Though volume limited, from what you are saying.
Made couple boxes for mac6. Rst28f and nd28fw have the same cutout so I will try both. I am not that good for designing passive crossover, it will take a lot of trial and error until i come up with something acceptable, but yesterday i tried using dayton kabd dsp amplifier and rst28f and they sound awesome
Dang that 5" just went from the ugly duckling to the star of the show! Finding a tweeter that doesn't cost over double to match it's distortion and cross down below 2k would be quite the challenge. Good problem to have I suppose.
Dangit. I promised myself I was going to stop buying drivers until a few more builds whittle the stock down some. This isn't helping

That HD3 bump. If you want to try to maintain that 50db down distortion profile.
And to clarify I said ugly duckling since it seemed some folks were disappointed by the enclosure size it would need for 2-way. This would become more moot if used as a very low distortion mid.

I definitely like the ol Dynvox. I did have an issue of the surrounds coming loose were they are glued to the frame. Had to break out the CA glue.
I have a pair of the new style 6.5" Dynavox, might be interesting to do a side-by-side of the two and see if anything meaningful has changed over the years. Interested?

SIG150-4.
Wavecor TW030WA11
Distortion @ 2.83v & 4.24v
I mah have missed them, but did you do the MAC drivers with HD? It’s be good to see how they do versus the Daytona signatures
Nyet ^ (No in Russian, Not Yet, compound contraction in English).
Looking forward to the HD sweeps for the MAC series of drivers as well . . .
Huh. I thought those were posted. I just did the MAC-06. I will do the 4”-5” tonight and post when it’s quieter in here.
New mic so I re-measured FR and Distortion.
MAC-04
MAC-05
I'm surprised more people have not bought some of these drivers.
I don't see the MAC-6 sweeps anywhere yet but thanks for the data so far, hifiside!!
Got a pair of MAC-4's inbound . . .

Why below 2k?

The chopping block tonight.
I welcome the Dynavox poly-old-frame measurements.

SB17NRXC35-4
Dynavox LW6004PMR
Dayton ND140-8
Why were these so popular at once?
Still better than -40dB on all 3 of those. SB is the best HD wise, but all 3 are usable.

I had to do the same.

I can drop off the 5.25" poly as well.
I’d love to test them.
OK, I'll figure out a drop time.
That could be a really nice combo!
I have that Infiniti, 8 inch and 4 inch in my office too.
