Very D&B too ;) There are all kinds of benefits to doing the porting in that arrangement. |

Bigger is not a synoniem for a better performance..... A good design is when driver, cabinet and ports are optimised on each other. So it is possible to make a small cabinet with a great performance and vice versa. |

what are the kick bin just behind the wsx ?

It depends. If you want to go low and loud then you do need to go big. There are tradeoffs between size, spl and frequency. Otherwise we'd all already be using cabs doing 150db at 20hz the size of a matchbox. ------------- My laser stuff: http://www.facebook.com/SubsonicSystems" rel="nofollow - Frikkin Lasers |

@ TDA's home... I bet this is in his living room
outsourcing is very popular nowadays, for martin audio as well
kick bins look like HD215

I mean within reasonable borders. For example, my sub is only 700*600*900 mm (378 liter) wich is very compact for a double 18" cabinet and it goes much lower and louder than my Mach subs (481 liter) with the same speakers in it.  |

yeah man, the horn loaded kick bass section pushes the bottom end as well
...it's also possible to series tune such a design

they look a lot bigger than hd215, hd15 high is 578 so 578X2 -18= 1138
wsx is 574 width so 2X 574= 1148
so for me it can't be hd215, maybe tsw218...?

They are my own design. They came about because one of my mates wanted some subs that matched the external dimensions of two D&B QSubs stuck together. They are not copies however, I've never taken a QSub apart to measure it. The singles are in fact my prototype twin 18" cut in half with two extra sides fitted! They're a very good general-purpose bass solution, particularly for live music. Very good efficiency, very clean, natural sound, although a lot of that is owed to the 18Sound drivers. The triangular ports make for a very rigid cab which then allowed me to use 15mm plywood and thus the weight is very reasonble. Two people can carry a twin up stairs without much difficulty. |

I've been using g subs for a couple of years and I can happily say they are the most versatile, user friendly cab I have ever used. You will be hard pushed to find another double 18 that is so efficient. Just wondered, why 21/24 double cab??? |

What is this? A huge copy factory? I don't really get the idea of double 18", it just gets heavier! For horns it makes a little sense as they coupl & go lower, for ported it just seems even more strange as the simulation of 2 in a cab is a bit stranger than for one in a cab as far as I recall ------------- www.facebook.com/babysoundsystem |
