Seas prestige: anyone with experience?

[PV Audio 5,000+ posts]

Hey all, I finally got tired of my MTM dayton RS 7" towers, and want to step it up...and down a bit. I want to use the same woofers (I won't be able to afford anything better than them, nor do I expect to find anything that will be worth the extra money), but nix the tweeters. They were the short coming of the previous build. xover is a 4-O LR filter padded on both tweet and woofs. Here's the thing: I want to only use one woofer per cabinet now, as before, the bass could get kinda boomy on me when I would push 'em. And as such, I need a new tweeter to complement my new setup. I was lookin around on zaph and saw that the seas prestige 27TDFC did pretty well. Does anyone have any experience with these guys? Thanks for anything.

I'm actually listening to them right now on a custom pair of bookshelf speakers along with Dayton RS 150s. They are quite amazing for the price. Very smooth and neutral sound. I also tried the 27TBFCG, the aluminum version, which is excellent as well but the fabric dome sounds much more neutral and open in my opnion. You won't be disappointed at all.

I crossed it over at around 2200 hz with acoustic LR3 slopes. The high pass is an electrical 2nd order. The low pass is an electrical 3rd order with a Zobel. Impendance peaks at around 11 ohms at the crossover point but it is broad and fairly flat. About 3db of baffle step compensation.

This combination works out well but I would say it is pushing it as far as the high pass/low pass limits of each driver. You would not want to cross the Dayton over any higher because it's got pretty bad breakup but and the tweeter really shouldn't be crossed over and lower. LR4 or LR6 slopes may be more desirable but this config sounds great to me and I was satisfied with the outcome, especially at the price point.

I would post pics of the final product but I don't have a camera. I'll try to borrow one later if I can.

Hmm, so it's a good tweet then? I'm most worried about nasty break up and some beaming issues that the other tweet had. At moderate volumes, they were smooth as silk, but when pushed to their limits, they honked and squeaked when playing any horns, and just couldn't match the smoothness of the woofer.

Yeah it's a great tweeter for the money. The only thing that concerns me is your use of the 7" RS driver which will have even worse high frequency breakup. You sure the "beaming issues" weren't from woofer ringing? What freq./slopes were you using? It's even audible on the RS150s if cut the high pass and turn it up.

The 27TDFC has good enough off-axis response for me. They definitely "beam" as all tweeters do but this is at like 15000 hz using pure tones. With music it's a pretty gentle rolloff. I haven't done any RTA measurements yet on this system but I listen to these tweeers off axis all day long (because I use them as computer speakers) and they sound great.
