pandathe3 Posted March 5, 2010 Share Posted March 5, 2010 (edited) Hi all! I've decided to make my own 1x12 for practice and small gigs. This is the first time I've wanted to do something like this. For small cabs we all want the same goals: Small/Light/Portable, but is still able to put out some nice big sounding bass to cut past a drum kit without pushing it to far at all. My plan is as follows: 1x12 speaker (Not sure about tweeter) 8Ohms/400watts FR: will be decided along with speaker choice Ported Its going to be around '20 Inches wide x 18 Inches deep' for my rack to fit on top. The back panel only really needs to have a single speakon connector (Also a possible tweeter control) I've been researching and the Eminence lites look interesting. Especially the Kappas. I've heard alot of good things about Avatar also. I'm still unsure about the type of wood to use for my build. MDF? But, i think the biggest part i'm stuck on is the design of the porting to match the shape and size of my cabinet. There are alot of different porting variation (GenzBenz: Cross porting/Eden: Side porting/Tube porting) The one i am most interested however is side porting. Shall i have a tweeter?? I just want a push in the general direction. Cheers Edited March 5, 2010 by pandathe3 Quote Link to comment Share on other sites More sharing options...
Mr. Foxen Posted March 5, 2010 Share Posted March 5, 2010 Mostly covered in [url="http://basschat.co.uk/index.php?showtopic=79008"]this thread[/url] In particular, the link Bill provides to Greenboy's fearful designs, including a 1x12 using a Kappalite, probably best using that as its a free plan.

Phil Starr Posted March 18, 2010 Share Posted March 18, 2010 I build a lot of speakers but the best sounding one for bass was an accident in that it was built for PA and used when I was between rigs. The drive unit was/is a Beyma SM212 350W, 98dB sensitivity 45-6000Hz at -6dB. I chose it as it has an excellent excursion figure due to a long voice coil (xmax is 7mm) so it won't run out of bass at high levels. It has a cast chassis and looks to be well made, so far utterly reliable after two years. Available from Blue Aran. If you want the cabinet dimensions I could send them.

It looks really good for the money. Quote Link to comment Share on other sites More sharing options...
