Eminence APT-50 Super Tweeter Horn Driver
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?
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.
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.

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.
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.
