Hey Ron/Wayne
I'm not sure I'll use a tweeter, depends on the amps I'll use. I do have a set of the Fostex T90a supertweeters I bought used that I'm sitting one, we'll see if i need them. With the 300Bs, I may need them. But, if I use a digital amp, I may not, as there's so much more top end there. Once I get these built, I want to get your Yamamoto 45 in my system for a listen.
As for crossover points, I have been wanting to roll the woofer off at around 200 hz, then bring in the full range. Not quite sure where to have it come in though. Nor am I sure just what kind of crossover to use. I do know I'd like to use just a cap on the fullranger, but could go second order if needed on the woofer. If I do bring in the supertweeter, I would probably just use a small cap and maybe an L-pad.
The thought here is to clean up the full ranger. I've read many times where the full ranger will greatly benefit from not producing the lower bass notes. It seems that while back loaded horns and such are still fairly popular with the full range crowd, more a leaning towards rolling off the bottom end in the full ranger and bringing in a big woofer. Thus, you get a cleaner and more defined bottom end as well as mids and high frequencies. As long as you don't cross too high, you shouldn't loose the point source imaging.
Thanks again for thoughts and help with this.
