Brian Steele its version 0.3.

1. I see some horns have a slotted baffle, i.e rectangular opening where driver is mount instead of a normal round opening (Martin Audio WSX, Volvo Treter Mivoc 30Hz tapped horn, MarcO MicC-146 on this site) etc. Whats the effect of that?

2. Which amplifier do you recommend for running 2 x dual 15" (8ohm, 700W AES per driver) per channel? Any further advices?

Try Sunway copy(clone) of the famous LabGruppen FP10000q or DSP’ed version.
Two channels for the pairs of paralleled drivers and two channels for tops. Or you can go mad and use it bridged.

Or put something like Powersoft Digimod 1500 inside subs and make them active (this will allow you to exclude long high-gauge wires to subs).

Maxolini... there are several companies that can do what you require, but it would probably be helpful if you said where in the world you are, that way people can give advice. If not, just Google it.

Default assimetrical version

hi, I was intrigued by the project, and despite the detractors I decided to use the idea to build my 2 subwoofer, to put under the TV at home, obviously i can not be width (they go into an apartment) .. so I decided to rotate the system, I know that but lacks the character of the roar ,the symmetrical woofer loading ... rather I worry about putting the woofer too close to the end of s3 ..

@Maxolini - sorry for not acting on this in time, the answer is unfortunatly no from our side regarding the DXF, all we have is what is posted on the blog. Normally a cnc-shop should be able to convert the drawings into what whatever format they need, and make any alterations in order to obtain the panel interfaces the need for assembly without impacts on the design.

I currently wait for my two ROAR15's to come out of a local cnc shop using only the drawings published on the blog, so far no problems, expected delivery is in early november, they will be loaded with B&C 15sw115's.

@sgarfa - cool! We conidered a not fully symetrical (angled) resonator initially, but in the end we went for a striaght one with split path seeing as that brought along additional benefits regarding the complete cabinet in the case of ROAR.

If you are putting the enclosure under a TV, then why design a subwoofer with an F3 of 40hz
