subwoofer to digital music and movies

There are a number of subwoofers that offer dual system connectivity. You may need to do some homework and ask questions via email. Keep in mind a subwoofer purchase should last you through many system changes. 

After reading Stereophile's Larry Greenhill review of the $800 MartinLogan Dynamo 800X were he needed to use a $3500 crossover to reign in the effects of the designs built in nature. I'm reminded of a similar experience with a friends $8000 British made REL Studio III.

Aside from moving production offshore REL hasn't done much in the way equalization R&D. Continuing to take the signal from one's amplifier as a means of extension or whatever they call it didn't begin to cut it when we stacked it up against a couple of modern designs. I guess I stand next to mzkmxcv in my regard for the brand.

There are subwoofers that can easily integrate unnoticeably with any speaker whether its playing music or a movie. A subwoofer / speaker matching list? WTF! 

I was set on svs, demoed the couple of svs and for music the rel t9i sounded far superior.  Went to another audio store, demoed the t9i against comparable JL model.  For music, rel wins for me. Have not demoed in HT.  Rel just sounds tighter and more musical to me and wife agreed.  Guess it's all personal preference. 

I sold my earthquake sub and purchase a JL fathom f112. I am speechless as there are no words in the audiophile dictionary to define its greatness. Once the system is perfectly dialed in (which took me weeks), for the first time I have jumped off my seat watching movies. In 2 channel dedicated listening, I cannot directionally point to the subwoofer, yet it fills more than just the lower octaves. Never understood until now when folk talked about the vocals and airiness coming to life in music because of a subwoofer. It's awesome!!! 

I did not demo the fanthom f112, out of my range. I demoed e110,  was trying to keep it under 2k so I could get 2 subs.
