Hi there, I'm looking at building a pair of MTH-46lc and am interested in B&C 18NW100 drivers.
www.bcspeakers.com/products/lf-driver/18-0/8/18nw100

Can anyone please advise me on whether these are suitable for the MTH-46lc and how they would respond in terms of low end extension and sensitivity.

Could I expect a noticeable improvement over THE BOX SPEAKER 18-500/8-A

interne:52.4cm, externe 56cm !!!!!!!!!

i would say internal width 52.4cm, external width 56cm means the thickness of the sides is 3.5 cm this would mean 17.5mm ply is used!!!!!!!! i think external should be 57cm..............
