Here are the specs :  http://www.elderaudio.com/products/MultifunctionSpeaker/ESSeries/2009/J218.htm
102dB/1W/1m sensitivity, 1,000W"RMS" and 134dB maximum output.  102+30<134, so where did the extra 2dB come from?  Apparently because in the manual the power rating is given as 1,600W/3,200W/6,400W.  But then the manual also refers to MDF rather than 15-ply Birch construction, to the trapezoidal design when it shows a rectangular box, to the HF transducer and horn for a sub, etc.  Some of these issues may be attributable to language factors but they do not exactly inspire confidence in the product.

Any new product that competes by being cheap is / should be guilty until proven innocent.

Has anybody heard of these chinese subs before ?
 
I'm in Australia , and after a double 18 sub . It's pretty slim pickins' from the local dealers. They don't keep any stock for me to demo.

The cab is 15mm birch , and pretty weighty.


Here are the specs :  http://www.elderaudio.com/products/MultifunctionSpeaker/ESSeries/2009/J218.html

I can get them for about $1400AU (our dollar is close to parity with US$ at the moment )

The only other contender is the mighty SRX728s , but it's an extra $1000 bucks. :(

thoughts ? opinions ?
