Maybe Im being stupid here, or blind, and I haven't read the whole thread... but how is that a 6th order BP when the front of the subs are clearly not firing into a secondary chamber? They just fire into the cabin directly, implying a simple ported setup (albeit with some front-loading on the subs due to their firing direction).

A 6th order means a ported enclosure on both sides of the sub. Im just not seeing that from the video.

Box is a 6th order.

The Center Chamber is only so wide, and has a depth and width to it.

Albeit it is probably tuned very high due to the enormous amount of area, but it is still a chamber.

So the center 'chamber' is also considered the 'port'? I suppose in the sense of a transmission line you could call a 5 sided box a ported enclosure. But wow. lol

In a 6th order you want the front chamber to be a large as possible.These boxes do have 4th and 6th order similaritys but are not true 4th or 6th order.

wow so these are not true bandpasses wow!

hello, chaps my name is Henry. i have aspergers syndrome and subsequently i am responcible for the design u see an garreths car and a few others that are being used in the uk that follow my same theory. the design does not behave totally like a 6th order bandpass. though sixth order series tuned bandpass is the closest relative as far as alignments go. the the tunnel is a quasi chamber if u will. more of a loose Q control, filter and resonator if u like. Q control like the throte area of a front horn or a k coupler. at high frequecy the chanmber, dependant on volume and opening will load and become resonant. below this point the tunnel is a directional coupler. the port intrution into the tunnel is a phase plug. i designed garreth's (scruff) to be a bottom end monster. and it is. however, fusion uk approched me to design them a show car for their reactor range of drivers. this is a full range monster and has achieved 150db+ in the Propper Droppers (streetbassers.co.uk) format (door/window open, TL on passenger headrest) @ 20hz, 25hz, 33hz, 40hz

peak 57hz+2db! flat as hell,

and all from 2500wrms see my avitar

Im not sure what you having Asperger's has to do with any of this, but welcome to the board. Thanks for the info on your design.

oh sorry, just incase i sound rude at any time. i sometimes upset poeple without wanting to. oops. accoustics, areo/fluid dynamics, and electronics are my key interests. Henry got to go out now! sorry dude's. check out

no one has said or asked anything about how much power the subs are receiving...

so, what kind of amps and how many does he have?
