Merton Posted September 16, 2008 Share Posted September 16, 2008 Hello! This is really for Alex and BFM (plus anyone else who knows). So I'm going to be building a 1x15 cab which is designed to be identical to the 1x15 "cab" in my V-Type combo. Yes yes, small enclosure, not much bottom end etc, but I like the sound I get from it and it's bloody loud. So the question is this. The combo is rear ported. I'm not convinced my woodworking skills are good enough/tidy enough to rear-port my cab, so therefore wondered about front-porting instead. This means I can hide the ports behind the speaker grille so any making good will be less obvious. Suddenly the cabs are no longer identical, HOWEVER I do know that port position is a moot point (i.e. you can put them where you want them). But will it have any bearing on the phase relationships at f3 etc, if one is rear-ported and one front-ported? My head says nay (i.e. it won't make a difference), but I want to have an expert tell me the truth, the whole truth and nothing but the truth Quote Link to comment Share on other sites More sharing options...

So found some black pipe instead and cut two bits to size... 6cm diameter port tube anyone? Quote Link to comment Share on other sites More sharing options...
