Have you seen all the subs on the market . It is mind boggling . You have little 10" cubes Sun sub woofers going up to SVS subs 1/4 size of a piano , and everything in between . You have subs with built in amps ,subs with external amps . There are ported, sealed enclosures and some with virtually no enclosure , so on so on . Nowhere have i seen an article explaining to people the ins and outs of sub woofers so they will have a base knowledge should they go out looking for one .
I have 2 15" subs in an 80 cuftsealed enclosure .That is the stage area under the screen .and a 120W amp to power the spkrs . I havnt put in a spkr roll off so they go 80 cps down to DC .This hasnt been a problem , so far , touch wood . aAs long as there isnt too much distortion coming from the woofers I suppose it realy matter what woofer one has , as long as it moves enougth air and you are happy with it . Just my thoughts on them . Regards Sparkamp .
