Interesting sub

These are for reducing the effective cabinet size. Usually these pipes will be outside but will be hidden behind some other cabinets. Probably to make it look like a real monster they have made it like that.:)
Those pics look like photoshop tricks to me. :)


PS: I hope Anthony is as good with photshop and our pics from the meet :) (I want to look more muscular)
these are ported subs and in ported subs, there is no requirement for the port to be inside the box. most people do it inside as otherwise it will look ugly, but you can have it outside also, that reduces the requirements on the box size also.
check out the hsu sub with turbocharger, its just the same thing. the port is extended to get a lower tuning frequency.
For excellent sound that won't break the bank, the 5 Star Award Winning Wharfedale Diamond 12.1 Bookshelf Speakers is the one to consider!
