Why don't I see more about these two drivers on here? Both, especially the 10" have pretty good specs for bass cabs. They also both have fairly flat response up to where a tweet would be used. It seems like these would be the drivers to use for any vertical cabs or vertical pa columbs. I actually have the 10" on order with the apt50 tweet and 3.5k crossover. Almost wish that I would have got the CX12 because the response is flatter but, the CX10 has 5mm xmax to the cx12's 3.5mm.
