An externally hosted image should be here but it was not working when we last tested it.

Yes, it is a very useful research tool, people here and everywhere use it all the time to discover things. I'm sure it will help you find what you need to know. I suggest you go and have a look and then if you have any specific questions you could always try asking here again. It may not seem like it, but you have been given a lot of good advice already.
how can you not find this? using the forum search tool is easy...

What he said.
Since the OP doesn't show much sign of improving their behaviour, I'm not inclined to help much futher.
They want a £100k system but can't search the forum.
Chris
doesn't matter where he's from he just wants to make copies of a high performance sub for his own use without all the the hassle of understanding the design he'd be copying...
Wait brother I don't wanna copy anything. If you have any problem do revert me the same in personal msg. I just ask any similar to La or next pro audio. I know very well what is copyright and patient right is so it will be more fare keep your mouth shut.
Apart from doing help.

well i was trying to point to two public domain designs in a previous post and perhaps you misunderstood me, but as of yet no one knows the inner working of the subs you where asking about hence no plans.
so if stating that copying a design offends you sorry. but copying a design is kind of the essence of diy sometimes...
if you could be clearer as to design goals and end use specifications you may find you'll get more appropriate responses

I´m also very keen on these.
One "side note" - for very large rigs, I´d use FLHs. Look what BH760s can do.... (also under copyright, but we already know the inner workings).

There are plenty of these floating around in every corner of India, and having heard these "subwoofers" I can say that other than producing a one note bass it does pretty much nothing. What it does in turn, is put the driver under immense stress.
Rademakers: It´s called accoustical loading. Once you don´t use it as direct radiator in infinite baffle, you always load the cone somehow.
Of course, this one is quite normal for 15"s, not immense.
But due to the construction, I can see how it can be "one note bass" for bass heavy songs. as it cannot play low. it´s closer to kick bin. Good for 60-130Hz.
