an economic diy sub to compliment EV ZLX12P

My first attempt at a blog so i hope i dont bore the pants off you all!!
I bought a 2 way so called 1Kw integrated speaker some time ago about which I have written various posts in the forums, management overview better value for money than DIY but vastly inflated specification as all similar units, actual measured output around 110dB max and LF rolloff starts at 80hZ!!
Soo it needs a sub!!
well if like me you like your low end forget the EV sub (ELX118p) and most of its compatriots for two reasons, one is rolloff starts at 40hZ or above, and 2nd is cost!!

Looks like i just use edit to add to the blog!

So to continue I used the UNIBOX spreadsheet (free) to model various drivers and box combinations, true to my namesake I started off with large Fane drivers but was scared of the price!! However I also discovered various nasties with ported or tuned enclosures most notably you tradeoff an extension in the 40-60hZ range for a much sharper cutoff...
