Update to NatalieP?

The TL Be dome in Europe costs the same as the Be domes from SEAS and Scan.

Don't forget that the SS9900 and SS9700 are essentially the same tweeter but with different face plates. One of the advantages of the older scan tweeters is they have lower 2nd order products. Their 3rd order isn't quite as low as the newer stuff though. I've had my eye on the 71000 for a while, it seems like it performs just marginally better than the 6600 and I like it's sculpted rear chamber too, even if it's only really cosmetic.

That is what I thought too but according to Jeff...

The 9700 has the same dome assembly and voice coil as the 9500, but it has the same motor shorting rings and cap as the 9900. It does not have ferrofluid. It has a smaller chamber, different pole-piece damping, and a different faceplate than the 9900. The 9900 differs from the 9700 in these ways as well as having a different dome too. The only thing the 9700 and 9900 share are the same SD-2 motor design and voice coil. The impedance curves are very similar, but the 9900 has a little higher midband sensitivity.

I haven't used my 9900s for about 20 years or so but they were always my reference back in the days. I always assumed technology had moved on so they've been laying on the shelf ever since but now I think I'm going to wipe the dust off and let them sing again! Got a couple nice 6,5" I'm going to pair them up with. 8)

I think the 9900 were a little ahead if it's time with the wg wich wasn't really fashionable at the time, maybe that's why they never got the same popularity as the 9700, well that and the size and price...

[Hdale85]

There any way to find out if it's really pure beryllium?

[Hdale85]

Looks like the ES140Ti is back in stock Jon.

Hmm as far as I know the dome/coil assembly for the 99 and 97 are the same. You can buy replacements from Madisound and the 93/95 share a part as do the 97/99. I thought the main difference was that the 93/95 had perforations in the former to allow the ferro to flow better, and the 97/99 obviously did not.

I just checked because I was of the same opinion as you but they really are different. Apparantly 93/95/97 share the same dome and vc, unless there are typos over at Madisound.

Maybe the SS9800 could be another contender, best aluminium dome available rivalling the SS Berylliums in performance according to Troels.

Interesting that's changed since I last looked, or perhaps I am remembering another website. Here I found it.

They sell the same part for both and then something different for the 93/95.

I guess we will never know. I did try and buy a replacement for the 97 from wilmslow audio a long time ago, I still haven't repaired that tweeter, but whatever it was they shipped to me wasn't the same as what was in the tweeter and it wouldn't align properly in the gap either. Needless to say I sent it back.

The good old russian chap has done a recent measurement of the 99 too. So now he's done with the 99 and 97. They are very similar in distortion performance and both perform very well. The 99 is ever so slightly better though.

It is a fantastic tweeter.

It's the ES180ti that's been out- I will order some more ES140ti shortly- after back from this next trip!

[Hdale85]

Oh well a week ago or so the 140 was out as well.

thanks for the links- checked that out. Guess the only thing to do is buy a pair and test them, too!

[JonMarsh]

Doesn't sound right to me either.

You can get them from Solen for $300 each. Considering what their ceramic dome units sold for, and that others have bought them direct from TL at that price, I guess it's real. Something else to put on the purchase and test list.... maybe first!

[Hdale85]

Yea that's a steal for a BE tweeter.

Haha, thumbs up for the good old revelator. It's funny really the design is pretty old and for all of scan-speaks new tweeters, it still manages to hold its own, most notably is the fact that 2nd order is much lower than their newer offerings.

[Hdale85]

Are the older revelator tweeters cheaper now?

[JonMarsh]

It's 5:20 in the morning, I'm at a nearby Starbucks to home, I've got a full tank of gas, and it's 866 miles to Burlington WA. No cop tires, no cop suspension, just a Honda Element in good shape with a 5' X 9' motorcycle trailer behind me, and a lot of miles to go in front of me. Should be there Friday afternoon.... where that RADD suspension Yamaha GTS1000 is waiting for me.

Road Trip! :B

I think my GF thinks this is the craziest thing I've done since I met her... OTOH, that big shipment of LBL for the new speaker project arrived while we were down in Santa Barbara, so we may be running neck and neck on these two events.... :W

Well, you guys have convinced me for now- I'm ordering a pair of these to check out. But I'll probably also order a pair of the Be TL tweeters. And at this rate, there will have to be three versions of the NatalieP ES, all with different tweeters- choose your preference! Maybe 4, if the ceramic TL N26 requires different optimizations than the Be N26.

I had a weird dream last week, too- an outlandish system, a 2.5 way with the 5.5's and four of the ES180's in each cabinet for the 0.5 way part. Yes, that's 2-5.5" and 4 7" in each cabinet. Must have been something I ate... :B

[Hdale85]

Doesn't sound that crazy, my Dynamic 4t's aren't far off with the 4 RS180's and 2 tangband 4" mids lol. Although 4 ES180's gets pricey!

[---k---]

If Jon ever has a garage sale, it might be worth driving a Uhaul from Chicago to Livermore and back for.

[Hdale85]

You got that right!
