Agree with the 10F rec. If you're going to crossover that high (800hz), system power handling is going to completely depend on your woofers.

If you really want a woofer that's little bigger, the 5.5" SS 15W8434G also has a very smooth top end

dome mids are not popular but this Zaph's design is rated top class Zaph|Audio - ZDT3.5 it uses Dayton RS52 dome, it has diameter of 52mm (2") cloth dome. Don't expect much bass but dispersion is wide.

I was going to mention the Zaph ZDT3.5. There was a Zaph shootout over at HTguide.

rythmsandy : "I have seen dome midrange from 800hz to 4.2khz and there is no breakup in this region. "

Really? Show me which one.

I fooled with 2" dome mids for a while (admittedly long ago) and concluded that they have little value unless one is building a 4-way. What worked best for me was a small mid-bass of 4-6" like the old Dynaudio mid-bass, or maybe a small Focal like you'd find in an MTM system. I think the crossover ends up in an unfortunate place with the 2" and it didn't seem to match up well with any serious woofer.

agreed on that behalf that matching the speed of the dome drivers is tough unless until it has to be really fast.. yeah domes do well at higher crossovers like 1.5khz and up and I would like to cross it at 2khz especially the 2 inch mid dome as there is no problem for the midbass driver doing till 2khz..
