I agree with Philb7777 suggestion. There are fab powered subs avail. You can play around with a pair of "great" speakers forever and not attain the balance available with a single sub. Avoid inevitable added complexities. Your existing amp & speakers will continue the magic you now enjoy. Dial in your bass to virtual perfection with the tuning adjustments of a great powered sub. Get a great dedicated interconnect for the sub. Heaven awaits :). I am envious of your situation. Oh to have such a decision. (By the way trying subs is easy). Goodwins carry the JL line and should be happy for your call.
Speaker input, which one, Magico, Avalon, Yg, Rock
Tough decision, Have recently updated all my Spectral with all the latest Spectral, 400 Dma, 4000sl, 30ss11. I currently have Avalon Edilons, 2002 purchased. I like the sound but am looking for a better bass. I like music not over detailed or bright, I need to hear before I purchase, but will never hear all of the above in one place. I would appreciate input as they relate to Spectral . I am considering, Magico q30, Avalon compas, Yg KIpod 11passive, and Rockport Atria. All are excellent speakers, but which is the most musical and fits my 15 by 18 by 10 ft room. Thanks. , I also like the soundstage I now have
