Questions:

At what frequencies is it going to start comb filtering when the neos are cut to the metal?

About the array, do they need BSC?

I am thinking of electronic crossovers but I have to save for that and I will do that when I have enough neos and little woofers to rebuild it. I was thinking passive for the moment but you are right it is not for begginers hence the ask for help from experts if any are so inclined(It would be christmas in my newbie ears). For the low end? A pair of stereo subs.

Thanks in advance for any help.

Mickey.
