New Tweeter

[Fangor]

I’m seriously considering matching this new tweeter, Peerless DX25BG60-04 1" Silk Dome Tweeter at PE with the Rival Acoustics R176-CP-08 Carbon/Pulp woofer.

This new tweeter looks quite nice but I am not familiar with Peerless quality. What are your thoughts?

 

[CharlieLaub]

Peerless is great, but they advertise this tweeter can be crossed very "low" but it's a 25mm dome with 0.1mm Xmax. That just doesn't add up.

I have three of the ring radiator version, XT25BG, which works great crossed low but relatively narrow dispersion.

The Rival sounds like a great/fun driver to try. Is it the one that is discontinued?

Best,

Nope- just on sale. I also have a pair.

The DX25TG09 or TG59 can xover as low as 1.5k if required, with careful implementation. I had to comp the Fs, but it definitely was quite capable.

rival acoustics?, i don't know it.
someone has used them ?
are they good ?

 

[wolf_teeth]

Very good drivers. They are somewhat new to the DIY sector, but up there with Wavecor, Usher, Scan Speak, in terms of quality and distortion measurements. I highly recommend them!

Judging on overall build quality and performance I have to agree with wolf-teeth. I got the kevlar ones when they were on sale and will be getting some of the coated paper ones that are on sale now. The price seems low for drivers like this. I'm thinking its to get them known.
I see rival makes caps too. Have you tried them?

Maybe SB Acoustics :: SB29SDAC-C000-4

?

 

[wolf_teeth]

I have a bag of the Polar Caps, and will be evaluating them. FWIW, I also have some Clarity CSA and Meniscus Cebo caps to try as well.

The thing with some of these low apparent Xmax tweeters is that they have a large proportion of their coil still within the gap once xmax is exceeded so distortion doesn't rise as dramatically as it could do if the case was otherwise.

Pyle do some good high power tweeters,

What do you think of this one? R176-PV-08 Carbon/Pulp

I agree with Charlie Laub... Don't think the Peerless DX25B would be appropriate for low crossover applications. Visiting the Peerless spec sheet I see it does infer high power handling, but do not see anything about low crossover use. One big give away on the spec sheet, in addition to the tiny .1 MM peak Xmax is the test frequency range starts at 2,500 Hz.

There are a few Tymphany - Peerless designs, and expensive to boot that can play down to 1.5K. Take a look at the spec sheet for P/N BC25TG15-04.

You see a tweeter with a .6 MM peak Xmax and it's power handling (test) frequency range that starts at 1,100 Hz! Huge difference. I have used this tweeter and for under $15.00 each it is remarkable. I do suspect the DX25B is better, maybe much better from 2,500 Hz up.

There are a couple advantages with the DX 25B, slightly more SD, handle a bit more power above 2,500 Hz and a db or so more true efficiency.

It's likely NOT MUCH different than the P-8 or CP-8. From what I've been told, the coating on the cone is a different blend and that's about it.

What's with the price? It is unusually low for such a driver. Can't fight the feeling
