Stand Alone Super Tweeter for Revel F208?


Hello,
I would like to add some sparkle to my Revel F208 speakers. I recently bought some Totem Hawks and Gallo 3.5s and the top end sparkle is amazing. Any recommendations?

Townshend Maximum Super Tweeter -around $1599 full retail (musicdirect.com).
Townshend is a good choice, as is the Enigmacoustics Sopranino

I do however have to note that a super tweeter should not add "sparkle" to your speaker. If you can hear the effect of a ST as sparkle you probably have the cross over set too low or the ST level set too high. The ST should be heard more as a tightening of transients and a greater appreciation for the space in the recording. You shouldn’t actually be hearing the ST (unless you are a dog or a teenager)
I feel like the Revels could use more air. Things like triangles, bells etc. are there but they aren't as sweet as the other speakers I mentioned.
Triangle would be one of the candidates, but other instruments have even more energy above 20KHz -- this is a very interesting article on the subject

Totems have ringing tweeters, that's the "sparkle" you're hearing. Revels need no help in the treble region. 

Agreed on previous comments - a super tweeter will not add sparkle.  Most of these drivers can and will reproduce frequencies up to 20khz and beyond.  You will really not "hear" anything a super tweeter would potentially add, unless you have a very damped room (with lots of sound absorption).

It's amazing that many people do not realize that much of the perceived high frequencies are actually coming from BOTH the midrange and tweeter.  There is a huge amount of high frequency detail that comes from midrange drivers as low as 3,000 to 5,000 hz.  The quality of the midrange can definitely affect how you feel about the "sweetness" of the highs.  I have experienced this by comparing a coated paper midwoofer with a coated magnesium midwoofer - in the exact same cabinet with the same tweeter.  Crossover at that point was 3khz.  So, if you love the sparkle and sweetness of the totems or Gallo, it is likely that the Revel sound more "sterile" or "flat" to your ears.

A friends B&W 802D2 has that sparkle I'm referring to as well. Ringing tweeter also?
The B&W D2 have the woven Kevlar midrange drivers.  These are nice, but they do suffer from the typical Kevlar breakup.  This is most likely what you are hearing.
The "Kevlar breakup". This is similar to the "Carbon fiber crinkle".
Change the tweeter caps to Mundorf Supreme Silver in Oil. 

And.... bleah! 

I do not like that sound, but that will give you what you are looking for.

That gen revel uses a titanium tweeter I believe, I am familiar with it and never found it lacking air.  This sounds like it may be a system synergy issue. 
It may be a good time to talk definitions. Air to me is different than sparkle and scintillation. Air feels more natural, like you are hearing the room itself. Sparkle/Scintilation feels like a Disney / Fuji film kind of extra color added.

I agree that the Revel tweets are pretty good! So that's why I suggested maybe the issue is the caps. The reason I don't like Magico SIO's is exactly what the OP wants. :)
I also like the Townshend Maximum Super Tweeters and highly recommend them.
Sorry, but I don’t understand adding a super tweeter. Did Revel not design the speaker properly? Does the speaker need some type of repair? Is there something wrong elsewhere in the system or room?

It’s like trying to add another wheel to a dually truck to get more traction.

Ah yes the splashy impressive metal dome that sells well because it sounds like hi-fi - sounds impressive, a great show and distraction but nothing like real music.

Try a tube pre-amp with old European tubes to add sparkle. The Revel F208 is the better speaker.
I have an Audible Illusions L2 tube pre now. You are correct. The Revels are more natural. They do everything. I guess I'm looking for high end that is not strident but detailed and midrange that is sort of polite and doesn't hurt when you turn it up. My cousins B&W 802D2 has a midrange and high end I like. I have tried so many speakers. KEF LS50, Tannoy XT8F and XT6F, Spatial M3, Golden Ear Triton 2, Dynaudio Contour S3.4, Totem Hawk, Gallo 3.5. Frustrating.
You can try a Schiit Loki and crank up the 8K Hz band and see if it gives you what you need...
@honashagen have you considered that the room may be the issue? Treating the room with for example a set of SR HFTs may give you not only control of the room but also an ability to tune the high frequencies to suit your taste. For example in my room adding or removing one HFT at ear level front and center has a major impact on specificity and level of high frequencies (this is even true for removing one ball on the Vibratron but the SR ART system is much more expensive)

My point is that you need to consider how the speakers and room interact and by adjustng this may be able to tailor the sound to suit your preferences

And this, in a nutshell, is what I consider the "high end sound" which JA has promoted. As the OP has put it, it is not natural, but has "extra detail." I call it ragged frequency response with emphasis on a couple of bands at the sacrifice of others. 

I make no value judgement here, but I am saying we need to be more aware, like the OP is, that it's far from natural, and if JA would stop calling it that, I'd be happier.

I tried the Schiit Loki Eq. Fun for a minute. Then reality sets in. 
Yes, the HFTs work -- the SR room treatments are a very effective way of dealing with even an under-treated room but they can also be used to optimize and fine tune a well treated room (like my setup)

They're cheap (or you can even DIY, search the 'Gon) and available on 30 day money back
Why not get the Bowers Wilkins ? You know you like them .
Almost forgot, try two things. Try toeing the speakers directly at your head, and also, try listening below the tweeter axis and above it. It's quite possible you will like the sound better with the speakers tilted, or your seating lowered. 

Best,

If a driver cone sounds like the material it’s made of, as is the case with many speakers mentioned here, then yes (yeah, yeah, I'm well aware of cone breakup measurements...) I’ll call it "ringing" since that’s what it sounds like to my ears. You can call it "sparkle," but I believe what you’re hearing is the inherent properties of cone materials masquerading as extra detail. That’s great for selling speakers to home theater buffs, not so great for long term musical enjoyment.


AMTs are in general, the opposite of what I would recommend for the OP. 

You can buy Mundorf bipolar AMT's at Madisound. Excellent performners, but you'll need to make a little stand. Not much more than a block of wood with a slot cut across it for the tweeter's lower lip. 

HOWEVER, they simply do not sound like what the OP is asking for. 

They are glass smooth. Supremely natural. 

Golden Ear Triton one's achieve this by a severe boost around 10 kHz. If that's the sound you want, you need to sculpt the HF response.

<< shiver >> god those speakers are ear drills to me.... but for many this may make up for lost hearing there, so the combination of spaeker + owner may be ideal.

"Ear drill" is the perfect description. I’ve always suspected they were designed for older listeners (the guys who tend to have money) with hearing loss.
Update- I bought a pair of Taket Batpure super tweeters. I wasn't even sure if they were working. I would try with and without and it seemed sometimes I could tell a difference and other times not. I have had them connected now for a couple of weeks and decided to disconnect them last night. Everything seemed flat and lifeless without them. If you connect these things by themselves you can't even hear them!
I have read through this thread,  overall, I agree with Erik.  I would do a tow in with these speakers and get a better handle of what you are after... A bit more tilt up of the treble region? 
Better air  & detail around the instruments?
More energy in the treble region.  
You can achieve some improvement in air & detail or maybe a bit more energy in the high frequencies with a simple switchout of a few capacitors with the same value. 
@honashagen -- congratulations, the result you have achieved is exactly what I would have expected -- do you also find that the quality of the bass has improved, with more crispness and tightness to notes? Anyway having lived with STs for over a year now every time I would no be going back
