technics Posted May 27, 2011 Report Share Posted May 27, 2011 hi all, in the process of making a new sub box, essentially exact same as my current one but with a double baffle and proper 45 degree pieces in the corners. the box is for 2 dd3510's and external dimensions are 300H x 850W x 550L, port is 48 sq inch and 580mm long and peaked at 33hz. now my question is i hear people saying DD's should be tuned higher to reach their potential as they dont like being tuned to low blah blah, anyway is this correct? should i tune the box slightly higher and if so how long should my port be? p.s sorry for the metric measurements, im an aussie haha, any help would be appreciated!

g6ryder Posted May 27, 2011 Report Share Posted May 27, 2011 I've also heard that dd like higher tuning they still get low while being tuned higher I would shoot for 36-38htz but never messed with dd subs I would tune higher yes Quote www.wooferwarehouse.com Link to comment Share on other sites More sharing options...

technics Posted May 28, 2011 Author Report Share Posted May 28, 2011 cheers for the replies guys, yeah i think il shoot for between 36-38 hz. pulled a 141db @ 33hz without the amp giving the subs full power, and the box not properly sealed in a 4 door sedans boot so i was pretty happy with that, hopefully with some higher tuning and proper tuning on the amp i can get around mid 140's.

RAM_Designs Posted May 28, 2011 Report Share Posted May 28, 2011 I'd stay in the mid/upper 30's as well. Their stiff suspensions help them maintain control below tuning. Whereas with some of my "softer" subs, they'll start to crap on themselves at 25hz in a 30hz box.

icewall Posted May 28, 2011 Report Share Posted May 28, 2011 yeah most people shoot for around 38hz Quote Link to comment Share on other sites More sharing options...
fecupe2001 Posted May 30, 2011 Report Share Posted May 30, 2011 my 3518´s are tuned to 32 hz , but yes , you don´t need a low ass tuning, those 3510´s can go WAY lower than tuning frequency without any problems, just saying...
