Dual 18 front loaded sub enclosure - plans

[dexijr]

I am new to this forum, and would really appreciate if anyone could help me with detail plans for dual 18 front loaded sub boxes, similiar to the JBL SR4719.
I am in Sydney, Australia.
Any guidance and advice would be much appreciated. Thanks.......

Sir,
Thanks very much for direction to the info. I really appreciate the same. It is a great starting point. Furthermore, I would like to know the size of the ports and the lengths too. I would also like to know about the internal bracing specs etc. I have 4 of the 2241H drivers and will be using them.
Thanks once again.
