Thanks for the link, the person writing that article said the lows aren't as good. But going by the others, he's just giving an opinion. Maybe I missed the testing part.
Even if, I'm going to use a line array with sub drivers, so I don't need the lows.
The white paper you have mentioned before talks about using drivers other than round and I didn't see where it said it caused issues. If anything, I thought it helped, like it does with the tweeters.
Can anyone give me any reason why 3x5's would not be the same as 4" drivers or 4x6's versus 5" units? It just seems like they make more sense in a line array because the center to center range is even closer in a vertical array......and isn't that a good thing?
I'm looking for something to fill up a room next to these subs:
