those ceramic domes are certainly cheap enough to play with and with ultra low Fs on all 3 might make for a good match for metal cone mids.

8w RMS on the beryllium? Seems a tad low... lol

**chad** · 05-03-2008

How much power do you think is going to a tweet?... RMS....

Toxis · 05-03-2008

I'm getting ready to put 100w per driver.

But seriously, 8? I'd be ok if it was 20 or so but man, just seems small.

**chad** · 05-03-2008

It will never see 100W for very long if at all before you visit Belltone, 8W is actually a realistic number. I run 25W/ch and I doubt they ever really see it, maybe the peak end of that for milliseconds but 100W for a tweet, come on man, think about it.

I am more impressed with their honesty rather than spec'manship.

Pull apart a dud tweeter and look at what is actually in play for the voice-coil sometime and you'll see exactly what I mean.

Clearly you have never seen a good 13 watt tube amp either.

Listen to Chad.

More than enough.

The Focal Be is 15 watts 200 max.

This Beryllium Tweeter looks very interesting fs 450

I would like to see a review on this one; I love the sound of Beryllium Tweeters plus you get to have your own personal Hazmat kit.

typericey · 05-03-2008

The beryllium is dirt cheap compared to Focal Be's...

...but a 4.33" faceplate?! daym!!!

tyroneshoes · 05-03-2008

nice find. I can try these out as have the microbe mini monitors (rs125 and the Tang Band silk like these) Specs seem like I can pretty much just drop them in.

Scott Buwalda · 05-03-2008

Power specifications by the AES convention are given *without* a crossover. As an example, the Legatia L1 has an 8 watt RMS / 15 watt max specification and the L1 Pro at 20/40 because I use the AES standard. It would seem apparent that they do too. 8 watts on a tweeter without a crossover means easily 50-100 watts with a crossover at two times Fs.

I'm using a small 15W x 2 for my seas neos @7khz/12db. they are holding they ground with midbasses feeded with 150W@8ohms and Rs52 mids moved by a 70W x 2 amp.
Highs are very subtle. Not big output, just detail and spaceness.

I'd be happy to "rent" one from you if you find them to your liking

Listen to Chad.

this is not my first rodeo bud. I've listened to probably 25 different tube amps in a home but to compare that to a car amp? Seriously?

Don't be defensive, they are just giving advice.

I like the look of em. I would be interested in a 3rd party review before I throw money into em though.

cvjoint · 05-04-2008

Very good find. I wonder what the scoop on the Ber. one does or the diffuser on the ceramic one. I believe Infinity uses something similar on their ceramic domes too. 30 and 60 degree plots would have been nice too, especially since wide dispersion is advertised.

manish · 05-04-2008

wonder how these sound compared to the focal version. Also does anyone make a beryllium 3" mid to match these? that with the 8"peerless would round out a nice active 3 way set for me.

cvjoint · 05-04-2008

You'd want to match these in a 2 way to put that low FS to good use. I haven't heard of a 3 inch ber. driver. Focal uses the sandwich cones for their 3 inch mid. That along with the ATC and the Hybrid were the best 3 inch mids I've heard so far.

manish · 05-04-2008

ATC and the Hybrid? i'm not familer with any of those. is there a link to where i can read a review on those and also a link to purchase either. I'm trying to find a 3" mid that has the same sound quality as the focal w coned mid.

Whiterabbit · 05-04-2008

dispersion will be based mostly on dome size. so check out any off axis plot for any 1" tweeter and note when the rolloff starts. That's about where you will be.

I'm aware size is the strongest factor. How about dome profile? I'd think the ceramic dome with the diffuser would have the best dispersion, and therefore be opt
