Default F/S Eastech / Philips Ribbon Tweeters

I had a nice collection of these Ribbons that sound terrific and are very economical.

The smaller ones are 2" and the larger ones are 3.75".

$10 dollars each is fine for these.

I have 18 of the 2" variant and 8 of the 3.75" variant.

Can be packed and shipped today.

Thanks,

Mark

What's the major diff between the two?? Do you have the spec sheets?

PM inbound...

*edit* I may be in for the 2" rather than 3.75" ones...

I have 2 pair of the little ones. They are cute and well built. They are good to about 5kHz. Keep in mind that they are dipoles. And push-pull electrodynamic planars, not true ribbons.

Philips had nothing to do with these. Eastech bought Monsoon (Canadian company) for the licence agreements from Eminent/Bruce Thigpen that let them build these. Think of them as 3rd generation Monsoons.

Attached are some preliminary data sheets i have and a response curve measured by Dan Wiggins.

Hi Dave...

Thanks for your help here... I appreciate it a ton...

These are SEALED in the back - and actually (for real) used by Philips for a line of monitors they made for certain markets...

I have used these down to 4.5K with (I would call it) excellent results...

Be well,

Mark

I don't think that would be an advantage... still for just $10

Hi, Im interested in a pair of the smaller ones (PFT 10).

Im looking into matching these with a 3" full ranger, the hi-vi b3s (lets see if I can buy it from elecres in the other thread...).

What about shipping, could you send by Priority Mail Small Flat Rate Box? According to usps: (up to 4 pounds) $13.45 8-5/8" x 5-3/8" x 1-5/8".

Thx
Alexandre

Hi Dave...

I understand your reply as so many people want Open Back for this type of driver... That said, my own experience is that a bit more SPL and the ability to (perhaps) play a bit lower can help with some designs...

They are a bargain for sure... and they do sound real good...

Thanks,

Mark
