Default Whoa, cool new tweeter from Peerless!!

Check this thing out! 25mm Corundum dome, copper, underhung, rear chamber, great power response, super flat FR, 1,200hz recommended crossover!

Looks like it'll be a giant killer! I kind of want to spend $100 right now on a pair!

Nice find!

It looks OK, but let's see:

Distortion
Compression
Waterfall

On the negatives, and it is potentially a big one! The sensitivity is unusually low for a tweet: 88.7 - This will prevent it's use in a few designs.

Hmm. Definitely promising based on the published data. I'd like to see the distortion plots through 95dB though. What gives me slight pause is the 18dB high Q breakup at ~27KHz. If that gets excited you may find distortion products folding down into the audio band. Either way, it does seem a decent unit for the money & worth looking at in more detail. It'll need to go some to be beating SB's 26ADC or the Seas 27TBFC/G though. If it can -we've got a new budget metal-dome champion. Possibly. The (relative) budget units that have my attention at the moment though are SB's upcoming ceramic / aluminium dome version of the 26ADC SB Acoustics :: SB26CDC-C000-4 & a cheaper beryllium dome model SB Acoustics :: SB29BAC-C000-4 -albeit not out yet & no word AFAIK on a date.

Scott,

True, but that can be damped. Also, that heat sink looks really really interesting. I wonder how that affects compression in long term listening? Will we see this chamber design come to other models, like the soft domes or ring radiators?


Best,

E

Maybe. But how would you do that? An electrical notch might help, but only up to a point, & physical mods would need to be very precise (far more than the likes of this ham-fisted oaf could achieve).

Depends on what it's being compared to & how it's being used / how hard it's being driven. So the question really is whether this unit is essentially excursion or distortion limited. We'd need more data to make any definitive judgement on that front.

Assuming it does provide an an improvement over xyz direct equivalent (just assuming) then hopefully we'll see them apply it more widely.

I think that's if you buy 1000 units though!

Im guessing they'll update the quantity prices when they receive their stock.

If a low crossover point is important, the 32 mm version, DA32TX00-08, is even cooler. 4,5 mm gap height yielding an xmax of 1 mm. I suppose that a design goal has been to achieve low HD down to 1 KHz, otherwise this motor design would make little sense. Might be an alternative to Bliesma T-34 if the lower sensitivity is not a problem. Data on the Nedlab and Tymphany websites.

Yea wow. well it seems a bit too good to be tru. Hope someone does some tests here. If its for real why is the price so low?

Nice low Fs but Im a bit doubtful can take it to 1200 hz without some serious issue above about 90db unless the motor/suspension really can make the swings. The lowish 88db sens would indicate that the motor has been configured for long travel. And I hate it when there is no indication of what X max means. Peak or Pk to Pk??

BTW Im looking for some experience in this area of low crossed tweeters. Someone mentioned they would like to see distortion at 95 db. What distortion numbers would you consider acceptable at that volume?? If I understand correctly many believe that at higher volume more distortion is acceptable than at say "normal" listening levels (whatever that is ha)
