This dome should be well suited down to Hz. Unfortunately I do not have two of this to test in a classic 3-way and evaluate against e. Distortion measured at 2. Measurements Above frequency response measured at 0. I’m almost glad I don’t, because it takes a damn lot of work to do so, and we may end up thinking we compare apples and pears.

Wouldn’t the ScanSpeak 12MU do just as well? This is midrsnge huge transition! Two ways of doing the same thing – and in the end mirrange matter of taste. Why they have gone out of fashion is a good question, maybe because 3-ways generally got out of fashion and thanks to D and other excellent dome tweeters, 2-ways took over although never able to deliver the same smooth transition between a 6″ or an 8″ midbass driver and the dome.
Dynaudio had the D52 and mid-domes and used them extensively in their commercial products.
middange Today we see a couple of 2″ and 3″ domes from China and rather recently reintroduction of 3″ domes from ScanSpeak. The midranye plot displaying the resonance at Hz, not something that should bother even with a 2nd order point of crossover at 3 kHz. The good question is what a 3″ dome has to offer against a lot of really good 4″ cone drivers available today? Distortion measured at 2. Baffle mdrange x cm, driver placed 40 cm from top. Unfortunately I do not have two of this to test in a classic 3-way and evaluate against e.
As can be seen, double suspensions secure stable positioning of voice coil in magnet gap. With an assumed point of crossover around 3 kHz, this is just excellent. This dome should be well suited down to Hz.
I’m almost glad I don’t, because it takes a damn lot of work to do so, and we may end up thinking we compare apples and pears. Some break-up modes appear around 4.
Soft Dome Mid-Range
This is a 16 Ohm driver Re TS data midrnge from the impedance plot. I think the claim has come due to ATC introducing double suspensions for their 3″ dome and people thinking this is good and all other single-suspension domes must be bad. Probably not as nice as this. Not cheap at all.
Still very smooth with only a small glitch around Hz. Above cumulative spectral decay. I’ve always found it strange to combine two 15″ drivers with a single 3″ dome as done by ATC in their larger studio monitors. Measurements Above frequency atx measured at 0. Piece of cake really! Hard to do a full test from either added mass or added volume. Above the midrange crossover based on simulation.
Apparently no symmetric driver is incorporated here to reduce impedance rise towards higher frequencies. Having a middome adds considerably to cost and crossover complexity. Above horizontal dispersion 0, 10, 20, 30 and 40 deg, off-axis. Above frequency response measured at 0. Wonder how it would sound.

At least from simulation from the large baffle. Large midrange domes are claimed rocking in the magnetic gap due to the single suspension, but I’ve never seen any proof of this – and it would probably be very difficult to do that test.
This is an easy driver when it comes to crossover construction and overall implementation. Not a trace of unrest from to Hz.
