Having recovered from the purchase of a 990/7700 combo purchase I am now ready to buy a sub. My main speakers are Paradigm Studio 100s. My biggest concern is that the LFM1 (or LFM1-Plus) is not up to the quality of sound of the Paradigms for music. It would be great to only spend 600 bucks but I would much rather shell out twice that than degrade the current performance I enjoy for 2 channel music. Of course I could leave the sub off but I probably wont. The Axiom EP 500 would probably be my next choice. I would really like a Seismic 12 but $1800 is just too much. Any thoughts or experience would be great.
