Why Oh Why Isn't Anyone Building A Decent 2 Way Stand Mount Using

First off, if you’re going to build a two way with either Silver Flute woofer, you’re going to need a crossover for the woofer and the tweeter.  Trelja is correct; look closely at the SPL graphs of the drivers, and particularly the Fs (resonant frequency) of your tweeter- as a very general rule of thumb, you’re going to want to crossover at least 2 octaves beyond the tweeter’s Fs.  I strongly urge you to google diy designs-  there’s a lot to this.  Also, there’s free software that helps:  WinIsd that models box volume for ported and sealed designs, and Passive Crossover Designer which will guide you thru designing a proper crossover.

Silver Flute is a pretty respected driver—the diyaudio website has a lot of build threads using the 6.5” woofer- some with the 8”.  The main issue is getting either driver to play lower than 50 Hz—box modeling actually favors the 6.5” over the 8” for hitting lower frequencies.  There’s a very long build thread that uses the 6.5” and a scan-speak full range driver instead of a tweeter-  crossover point is around 300Hz if my memory serves me.  Better known as a FAST design- Full Range Assisted Subwoofer Technology.
