DaveA's Fabulous New Improved Super Tweeters 2.0

Why are you suggesting the 110 instead of the 120? I looked online and there is only a 5mm difference in diameter? Is 5mm going to make a difference in blocking?

It you're going to do it, why not stack the deck in your favor from the get go? You will give up not HF sound performance by going to the smaller 110, so why not?  Since no blocking tweeter is best, shouldn't you make it as small as you can? When you look at the VOLUME of air it takes up (3 D) instead of just the diameter (2 D) it will work in your favor, making it even more marginal than with the 120. Just sayin'.....................

Just wondering, how do these tweeter horns compare to the Fastrac eliptrac hf horns that I currently have? They look very similar in design. Anyone compared the two?

Yes. The curves are better with DaveA's sMAHLs. But the eliptrac is not bad, just not as good. Why do you care?

Thanks, I was just curious if I should try them out later down the road. I'm more than content with my eliptracs, but it's always nice to know where they stand. I'm always interested in upgrades for my Belle speakers. I didn't see any comparisons mentioned.

I've measured and listened to them both with the same DE-120 driver.

 

DaveA's improvement is in the dispersion angle being  wider, smoother, the curve being much flatter, and it works down to a  much lower frequency, allowing you to cross at 3 to 5 Kilohertz. rather than the customarily 6 Khz. on Klipsch Heritage speakers, for greater "micro detail" with his version 2.0. His mating to the driver is better, and the curve is quasi Tractrix, not CONICAL, like the Elliptrac, which is a misnomer at best.

 

But all are an improvement over the stock K77, which is not terrible.

I have looked but cannot seem to find pricing on these units, is it available or still too early in the process?

 

Thanks,
Ed

Installed a pair of the MAHL lenses on DE-120's in my newly acquired La Scalas this weekend.  Have been running them for about 12 hours, and as Dave predicted, the drivers are a bit "scratchy" at first, but definitely smooth out, and the combo sounds terrific.  More break-in time today with the other new drivers.  I like them so much I ordered another pair from Dave yesterday for the other new LS.  Really appreciate all of the work and measurements done on these.  I was not necessarily a full believer at first, but I've come around.....

Thanks Jim. I only seek "the truth" as best as I can. Curves never lie, but it's the EARS that rule! (OK, and the Brain too, of course).

Ditto on the thanks. Peer approval means a lot more than my approval.

Another 6 hours with the DE120 with MAHL lenses, A55G mids and Eminence Kappa 15C.  Absolutely sweet.   My home anechoic chamber measurements confirm it.

Got rid of my chamber, it was a ***** to dust and keep clean.

Great combo on drivers. Which xover did you go with?

Oh man, dusting is the worst.....the Roomba keeps falling all over itself..

 

It is a DeanG A network with Jupiter Flat Stack caps, beautiful build, just a bit bright for me.  Will be switching this one out for a AA build soon.

I'm just glad they made it safe. I lost sleep over how to pack them and then held my breath the entire time they were in transit.

 

Networks, especially expensive boutique ones, are officially my least favorite thing to ship.

Thanks for the absolutely outstanding packing job on those.  I am keeping that box and materials in case I need it in the future for anything......

BTW Michael, i didn't mean to imply that I am getting rid of these networks in favor of AA's, just switching them to another pair of LS is all.

Ha, awesome. There were packed really well when shipped to me, but it was lots of bubble wrap and tape that didn't survive the unpacking efforts.

They're yours to do whatever you please? My emotional attachment ends with things the moment I decide to sell them. ;)

LOL. You are hilarious. If you mean your "home" anechoic chamber, it means it's been warm enough to do outside measurements, eh? LOL.
