Any thoughts on passive v. active speakers?

Stayed up all night thinking about this.

Next I'm going to throw my Braun L200s onto of my ADS810s and run them in parallel to get to 16 Ohms.... Actually, I only get to 12 Ohms with the ADS & the Braun, but its a step in the right direction...

For the two impedances to add, the speakers have to be connected in series, not in parallel. Based on a quick Google search, it appears that the L200 and 810 have nominal impedances of 4 ohms and 6 ohms, respectively. In parallel that combination would have an overall nominal impedance of (4 x 6)/(4 + 6) = 2.4 ohms.

Also, using non-identical speakers in series is usually a recipe for poor sonics, as their differing impedance curves will cause the voltages supplied by the amp to divide up between them differently at different frequencies.

We sold a LOT of 810's back in the day...how does it SOUND ?
Lovely amps...

Some people find the smorgasbord method to be a fun activity. Invite friends over, spend a few hours swapping cables in and out the system, do some critical listening and share some alcoholic beverages. You could get into an engaging argument about midrange liquidity or holographic cohesion. Does that sound like fun to you?

Alternatively, you could get a system like the Linkwitz Orion where the loudspeaker designer actually specifies what amplifier and cables the loudspeaker should be used with. The designer makes the argument that his loudspeaker do not require exotic cables or amplifiers. If you are more knowledgeable about amplifier/loudspeaker interaction than Siegried Linkwitz you'll be able to achieve superior results by carefully mixing and matching random components in an open ended system.

You could even go further along the line of system integration with the Grimm LS or the Steinway Lyngdorf S series products. Both integrate digital converters, source selection, power amplifiers, loudspeakers and cables into easily setup sound systems. I am told that both of these are top of the food chain type products. Both Grimm and SL started out as digital processor makers and then hired top designers to assists in other areas of design and manufacture.

The primary advantages of active loudspeakers is that they move the crossover from amplifier output level to line level and the load the amplifier will drive is a known factor. Basically less of your amplifier's power is not thrown away and the amplifier works into an optimal load. The execution of these concepts can be cheaply done with many corners cut or they can be done in a state of the art fashion.

Active is a safer bet if like what you hear and you don't know what to do to do better otherwise.

You are starting with some good building blocks for sure, but there is more to getting good results than the parts that go into it. I'd consult with some vendors/experts on teh products you already own and see what might happen.
