questions about MT-121 from 15mm plywood.

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   I'll be building MT-121's (Rog's design) from 15mm plywood instead of 12- & 18mm and i was 
wondering that  should the distance between the horn and the driver 
mounting stay 24mm?

If i make it 30mm as it would become the 
volume between driver and horn increases by 1.25. I'm just worried that 
this will mess something up?

Thanks!
