Ribbon Tweeters

Could it be that a tweeter with a range that extends beyond 20khz sounds more detailed and extended because it is working more comfortably within its range and not being affected by the mechanical limitations of the diaphragm. I would think that if a driver does not have that extention you could here the effects much lower in its response. Its like running a woofer a little too close to its upper limit. Also, HiVi (Swan) ribbons sound very nice and seem to be fairly durable. Dont know about others but the smaller HiVi goes down to 3,000 and the bigger to 1,700hz.

Every cone and ribbon tweeter i've seen goes to 25K+ hz's. As far as i'm concerned, there's no issue about any tweeter not hitting the upper reaches of fq's. How musical is a particular driver? That's the issue. But honestly you can ask 10 DIYer's and all will give you 10 different answers as to their favorite tweeter. BTW i just found out the Raven3 goes down to an incredible 500hz!!! But you got to pay for that: $3400/pr!! Next would come the ESg3 ribbon goes to like 1500hz.

The piega ribbon,mid system system in the c-40 plays from 350-47.5k.P-10 and 8 ltds & 5ltds from 450-47.5k and have a unique design differing from all other companies.
