The Keystone is as easy to build as a PPSL cabinet, and a lot less pieces than most portable tapped horns.

Jim,

48" max height , 20" width and 22 deep, low extension i dont care , i mean 40hz or 35 hz low is the most i want, it is for PA not for cinema

weight i dont care for the given dimensions, altough light magnet drivers are a plus, so i will like to have both options in case i want to go with the more expensive route

Now, i was thinking instead of a dual 15 or dual 12 , singles like the SS15
but smaller at the expense of injecting more power to them
what about a mini SS15, with dual 12 drivers or single 12" driver
Lab 12's i heard a lot or 3012LF,

another tought is the 3015 Tqw that bjorno posted
the size is perfect
but can that thing be fitted with dual 12 to get some more spl out of them
or i just a plain no and you need just a more powerful 15" driver

some ideas i just come up with

This seems like a good idea to me, possibly loaded with 15HP1030 or 15HP1060 depending on how the wallet feels about the weight. 22" depth should be easy if he is going to use 1/2" ply...

Thing is that the plans are scatered all over the place on the keystone thread
for example on the SS15 by jbell thread
he maintain like an index on the 1st post
with links of the plans and stuff

so you can easily print and start you project

As it says in the first page of the Keystone thread, plans are available in post #97.

Dude put in a little effort to get this done lol

I vote for the keystone design. No I've never heard Art's cabinet, but I'm sure it will cover the freq range you want, (35hz on up) with the power and DSP you currently have available, with ease. A pair of them will really rock most places




These are just screen shots from my iPad so they're not clear, but save them to your comp and print out in full size, they should be plenty easy to read and follow, and jot down notes as you're building in the workshop.

As I mentioned in the pm, a CS-30 style box might be better suited for you. Well not one, but four. Two placed wherever you would like. The other two next to or on top of them.

Post 9 of this thread is a rough plan on what the box should look like.

(4) Lab 12's plus some wood should be around $800 usd. Using 1/2" Baltic birch with bracing should keep weight down on those, and portability as well.

ic, so now, is keystone or CS-30.... i dont like lab 12 for the weight but you cant have all in life

what would be pros and cons of the CS-30 vs Keystone
