skinneyfinney17 Posted December 10, 2009 Report Share Posted December 10, 2009 so i just got my other Hdc3 and i was just reading to make sure before i build my box what to tune it to? i have a design that i made where its tuned to 32.69hz but i heard that its not good to tune hdc3 that low. i read on hear that you want to tune them in the 34-38 range. is this true? and this box will be a daily music player Quote CB7 wit bang Link to comment Share on other sites More sharing options...

Decaf Posted December 12, 2009 Report Share Posted December 12, 2009 shorten the port a little and give the subs the extra volume bracing and 45s will only raise it ~1-2hz at most Quote Link to comment Share on other sites More sharing options...
bgaccord Posted December 31, 2009 Report Share Posted December 31, 2009 I wouldnt tuned them lower tham 35,i had my 15 tuned @34 with a 4 cube box and the sub would make noise,like it was bottoming out,so i build a 3.3 cubebox tuned at 38hertz and it get way louder and no more noises from sub Quote Link to comment Share on other sites More sharing options...
