Rated 5 out of 5 by from Not bad at all!I've got this Eminence APT-50 Super Tweeter mounted on the Dayton Audio H08RW 8" Round Waveguide, xovered at 5k/12db. It actually sounds really good. Quite airy, open and bright. Seems to roll off around 16k, but you can boost the high end if need be. Doesn't sound like a "pinched" or "honky" type of a horn. To my ears, sounds like a decent poly dome, maybe just shy of a silk dome( I say "shy" because the horn loading gives it that "projection" sound). I'm going to use this setup again for sure!

Rated 5 out of 5 by from Great Top End Sizzle!!!I coupled this with an Eminence Beta-10CX 10" Coaxial Driver. It screwed right into the back of the magnet on the woofer with ease. After hooking everything to a Eminence PXB2:3K5 2-Way Crossover Board , It was simply righteous!!! My 1x10 bass guitar cabinet came to life. It was already great sounding but it went to another level with this tweeter.Awesome buy!!!

Rated 2 out of 5 by from an ok choice for basic needsthey do sound good for the value until even the slightest feedback, then gone as already posted. but diaphram swaps are less than 5 mins, and really cheap! sound scratchy at closer distances and fall short at long throws. there are better options for a few bucks more.

Rated 2 out of 5 by from Gone in a flash or should I say squeek.These things sound good untill you put a little feedback though them then they don't sound like any thing and its time to buy new ones.

Rated 5 out of 5 by from Brought my old speakers to life.I didn't know how flat my speakers hadbecome until I added these tweeters.Sounds like new speakers at a lot lesscost.

Eminence APT-50 Super Tweeter Horn Driver

I'm going to be crossing this APT-50 super tweeter at 5000k/12db where will be the power handing be at 45watts or 85watts and im going to protect this tweeter with a polyswitch fuse witch one of the polyswitch resettable fuse should i use for this tweeter

Asked by: hook
Polyswitches are a bit slow for tweeter protection. I'd humbly suggest using a #211 automotive light bulb in series with this tweeter. It has similar characteristics and faster response than a polyswitch for this purpose. Power ratings are subject to interpretation: these are system power ratings. What the tweeter sees depends on program material. The tweeter voice coil probably can't dissipate more than 5 watts continuous, but might be fine in a speaker system powered by a 100 watt or more amplifier when crossed at 5kHz.

Can I run this at 1,647k crossover 12db octave?

Cross over selection with 24 db/octave slope

The recommended cross over is 3,500 Hz @ 45 watts with a 18 db/octave slope. I would like to cross over a little lower to better match the Eminence 8" coaxial woofer. How low can this safely crossover @ 50 watts with a 24 dn/octave slope?
Asked by: jaypine
I wouldnt recommend going any lower than 3kHz with this driver.

I notice there is a titanium driver 1001 for the same price that compares to this driver . are these two drivers close to being the same.

Asked by: spunky
These are very similar drivers. The ASD1001 will handle a slightly lower crossover point and a little more power. The decision on which to buy depends on application and personal preference regarding the sound of a titanium driver versus a phenolic.

Crossover required?

I plan on upgrading a small Dean Markley guitar amplifier with the Eminence 8" Acoustinator speaker and this tweeter. Do I need a crossover? The probable answer is yes but just wondering.
Asked by: Jimmy
Yep, there isn't really a tweeter in the world that doesn't need a crossover. Tweeters are quite fragile and need to be protected from those nasty low frequencies. There are some good guidelines in the specs as to what crossover frequency and slope to use, depending on how much power you plan to deliver to it, so I'd recommend following those suggestions.Also note that you will definitely need an L-pad in the crossover. I don't know which version of that 8" woofer you'll be using, but the neodymium version has a sensitivity of 95dB/W/m, and the non-neo version has a sensitivity of 90dB/W/m, whereas this tweeter has a sensitivity of 105dB/W/m. So unless you put an L-pad in there, the treble will be EXTREMELY overblown.
