You use the crossovers on the 9835 to run your system. It has LP,BP and HP so you will be able to LP you sub (don't know the exact frequencies off the top of my head), build a band pass for your mids, and then HP the tweeters.
I ran the Lotus Reference mids off an A3 for month or so and they did nicely. Also ran the Lotus Ref fabric tweets off the front channels of an A5. Again, very sweet. The DLS Ultimate amps, IME have very good seperation in that you can get a very good sense where each individual instrument is distinct and clear in its placement on the stage.
Go Lotus baby and never look back!!//content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif
