A nice commercial kit- North Creek Pegasus

[Dennis H]

Yup, I don't get the new Seas tweeters either. 29mm domes but 26mm voice coils. More efficient but only if you cross above 3K. Who in the heck is going to cross a 29mm dome at 3K and pay the off-axis penalty? And $260 for the Crescendo? Things that make you go hmmmmm.....

I bet that crazy peak in FR on the T29AF-001 is where the horn unloads. It looks to me if you just put a first order lowpass at about 8.5k you would end up with a 2nd order acoustic at about 2k. That jives with the recommended frequency range of 2-22k and the specified 92dB sensitivity. There are a decent number of commercial designs that would fit into. Seas is probably filling a market demand.

One more post on this (off) topic. What do you think the odds are that Seas will release chambered versions of the budget wide surround tweeters? Does anybody remember if the last time Seas released a batch of tweeters they came out with all the variations at the same time (chambered, non-chambered, fero, non-fero, etc.)?

Speaking of North Creek, anyone tested or measured this NC-tweeter?

Seems a bargain with frequency response straight down to 1,5 khz and a xmax of 1mm (both ways). All this at $36 per pair! 8O

Even if they're not high end they have to be a bargain...or?

I've got a pair of D28's which we've tested, but I've never looked at this guy- the price is certainly right, and I wouldn't be surprised if it was a leader that price point. The Fs is a bit higher than I prefer in tweeters.
