I know that HD15 have to be 470mm+36mm(2*18)and that is 506mm.I found that 450 is ideal for me (first I have tops 450mm wide)and second and more important is that I need 450mm becouse of packing.If I loose only lower cutoff frequency I'm ready to "sacrifice".I found that this bass anyways don't go so deep,so 65 hz instead of 55 is OK.

So do I loose much if box is narrower (5,6 cm)?

Also I have 2 JBL m151-8 can I put them in box,I know they are not best choice but I have them already.

Thanks and sorry for my bad english
