Lighter weight sub?

<< < (6/6)

Tim Weaver:
Years back I built a pair of single 18's just for this one band that I did a lot of work with. For some reason this band did a lot of private parties in some rich guy's backyard and I wanted lightweight subs that were very efficient.

What I ended up with was the EV TL505 boxes in non-stepped down mode. I happened to have the EVM18b's kicking around so it made sense for me then.

I built these cabs based on the TL505 but modernized to use round ports and a truck bed liner'd finish. They looked nice actually. The comprimises I made were: They were efficient but didn't play very deep. They also were built out of a single layer of 3/4" birch ply and not very heavily braced. This made them both light and "stiff enough" for the 400 watts I would be throwing at them. They ended up being around 65 pounds each and I could handle them solo fairly easy.

If I didn't have the EVM18's laying around I would look for the most efficient Neo driver I could get and do the same if this situation comes up often enough. Just use the lightweight subs on these gigs and keep the Yorkvilles for everything else.

You would also want to look for drivers that have a lot more than the  EVM18B's 3.3mm Xmax.
 
Given more power, doubling displacement adds 6dB output, 15+mm Xmax is common now, and some 18" are in the 50mm range!

For sure! If I were buying drivers there's plenty of great, lightweight drivers out there to make some decent small and fairly light subs. I had designed a dual Eminence Kappalite 3012LF that looked promising. Would have had a good amount of chooch and able to be carried in one hand.

I use a pair of 3012 lf's plus a 6" alpha mid in one of my bass rigs.  That is a great driver!  I aso built a couple of small lightweight subs using braced 12mm baltic birch using 3012lf's. One is in use other another local sound co as the bottom of their drum monitor with a co-ax 12 box on top.
