After looking at the midrange domes that are available now and in the past, it got me to thinking. What are the limits of dome sizes? It looks to me that if the RS52 was a little larger it might be a much more useful driver.
Midrange Domes?

Originally posted by cotdtthere's a 3" accuton dome. the 2" tested very well, so i bet the 3" is even better.
From around 400Hz upwards it is really hard to beat ... Low distortion, high sensitivity (96dB/1W), almost unlimited SPL (will nudge 120+dB in peaks), no directivity problems, first breakup around 4.5KHz or so.
Ugly looks and horribly sticky coating that attracts dust and fluff aren't everyone's cup of tea, but I've learned to close my eyes when listening- Bottom

Thanks guys! I knew about the other drivers. Unfortunately, the ATC is a little pricey for me. I guess it is possible. Now, if PE could just give us a RS75 and a RS16 for a good price.- Bottom

Vifa makes the D75MX 3" dome which is used in the PMC IB1 monitor speaker.They use it with LR4 xovers at 380 and 3.8k.It may have been discontinued though so might be hard to find. http://www.pmcloudspeaker.com/ib1.html
They use the ATC's in their more expensive models.Last edited by Habs4life; 19 February 2007, 17:48 Monday.- Bottom

Checking at the Tymphany site, the Peerless-vline D75MX appears to be available. I believe it was used in the Coincident Total Victory. 76 bucks at Madisound.- Bottom

The Usher 9845 dome mid (~$70) is kinda largish. Highest you could use it is about 3khz due to its 150mm flange diameter (and assuming you use a neo tweet), but it looks like it can go reasonably low. Of course it depends on how loud you you listen, Usher seems to think you can use it as low as its Fs, which is 400-500hz. Good dispersion, pretty low 3rd order harmonic distortion.
FYI, PE has the .frd and .zma files posted.
Cheers,
Sam- Bottom
