i've never been able to find an answer to this question. i'm looking to build 95dB 8" celestion based two ways with ribbon/AMT/planar tweeters, but i also see that, especially with ribbons, good luck finding anything rated over 30w, but i've seen smaller fountek/aurum cantus tweeters in 100-200w rated speakers like the ones linked to below though i imagine the tweeters are padded down to match the woofer efficiency, so i don't believe the ratings directly apply to power ratings in a system, but continuous test tones. besides that, i've also seen compression drivers with similarly low ratings where it's expected that a PA speaker should at least handle 200w.
it seems like my "best option" is to just go with a more durable AMT and deal with a high 3,500Hz crossover right in the midrange where one doesn't want one if it can be avoided.
can anyone help clarify this. i'd like to find a 95dB+ ribbon that can be biamped at 2,000Hz and take at least "100 (system) watts" preferably with 3dB headroom as i'm building a high output system i'd like to be able to hit at least 115dB with. i seriously doubt everyone that owns speakers with ribbon tweeters is only feeding them 20 watts. i'm interested in the fountek neo 2s & 3s. i want a system that can do cowbells with wide dispersion and without horn shriek/sizzle.
