Just Arrived Today- TL Beryllium Tweeters (BIG Pics)

[Jeff B.]

These just arrived today. Haven't had a chance to measure anything yet, only can say they sure are heavy. Here's a series of pics to get the ball rolling:


That's right, the first drivers I've had that come with an MSDS sheet. Be careful with the Beryllium, it can be a hazardous material. No touchy- sniffy on the domes.



The come with their own individual response matched response curves. Look very flat, and 95 dB sensitivity.



Big whopping rear chamber.....

Here's a close-up side view:


Another view:



and finally....



More info to follow when I have chance to measure these.

Beefy! And 1.2 mm Xmax! Do you know the difference between the -A and -G?

Yes,

A = Aluminum former
G = Glass former (fiberglass, I assume).

I chose the A

Nice looking drivers. I know Be tweeters don't come cheap either. Focal uses Be tweeters in their Utopia and Electra lines.

I've been meaning to post the pics of my MgO in the Cecropia thread. I just haven't been able to yet.

Wow- MSDS....

They go for $349 Euros across the pond.

Msds? Last time I checked they don't use that acronym anymore. It is now simply SDS now. Be careful your paperwork is behind the times lol

Man, I sweat when I'm dry-fitting my $20 dayton neo tweeters into raw MDF after a routing session; I can't imagine how nervous I'd be trying to test-fit one of those into a slab of dusty, freshly-routed wood.

They should have the option of buying a $10 plastic template of the tweeter faceplate so you can use that for fit-up instead of the real thing.

Nice stuff for sure. Someday for me.

Yeah... The change from MSDS to SDS was one of the changes OSHA made in 2012 to conform to the UN's Globally Harmonized System of Classification and Labelling of Chemicals (GHS), third edition 2009.

Pretty sweet. They deserve a screen like the RS tweeters.

With the huge magnets and eight non countersunk mounting holes they might as well paint a bullseye on the dome. I think the plan is for you to buy three.......

I'm inclined to agree. TL makes a lot of amazing tweeters, but how many of them are impractically fragile? I think I read somewhere that their ceramic domes are about as fragile as eggshells. It's an impediment to me using them..and I'm a crazy audiophile nerd.

Plus the fine mesh grill on the ScanSpeak tweeters is super cool looking. I think I read that meniscus will fit them with a mesh screen of some sort, but I would like to see how that actually looks.

Look forward to the measurements. Prediction - super duper flat, super duper low distortion, super duper high extension, super duper low extension, okay dispersion.

I talked with Mark last weekend about this, and he said Eugen was planning to have grills for them, so Mark stopped pursuing that angle. Now that they're out- no grills. Mark said if they don't start to have some, he'll definitely pick that option back up.

EDIT: Mark said they are supposed to have grills by the end of the year, but Mark is still looking for maybe another option.
