JBL SR4718 vs. JBL 4645

[Chris Brown]

How would a pair of JBL SR4718 subwoofers compare to a pair of JBL 4645 subwoofers in a home environment?

Generally the 4718's seem to go for much cheaper. I've been aiming for a pair of 4645's with either 2245H or 2242H woofers but maybe a pair of 4718's with 2241G's would be good enough?

I'm only familiar with the 2241G and JBL specs Are 10 cu ft cab /400 cu in port for max perf.
you may have to build that cabinet....as I did .. x2..,... a 20 cu ft cab w/ 2 400cu in ports
