Thoughts on Active/Passive Speakers? Looking for pros and cons.


Hi all, 

I've normally discounted the notion of active/passive speaker combos, but am warming up to the idea and may give them a listen.  Golden Ear gets good reviews, but i'm intrigued by the new Paradigm Founder Series 120H.  

Curious if anyone has heard the Founders, or maybe compared the Active Persona 9H against one of the lower end versions.  

Thanks in advance.

There is a lot of misinformation in this thread. Fiesta 75 has it pretty close, active means "amplifiers AFTER the crossover connected directly to the driver". Nothing about digital, or analog or amps inside or outside.

If you see how much copper is in the passive crossover, then how much speaker wire is added on to that, with all of it between the driver and the amp, its hard to imagine how someone would view active as more complex. The amplifier cannot "see" the driver at all, it sees a crossover and speaker wire.

You cannot adjust driver phase in a passive crossover system- probably one of the single most important issues (a phase linear loudspeaker).

To argue that you someone is "taking away your options to switch amplifiers" is to ignore how much active is increasing the importance of the front end, the improved transparency in EVERYTHING before the speaker input. The amp, while important, is only one of many things that influence sound quality.  To hear a significantly bigger difference in tonearms, cartridges, phono preamps, streamers, CD players, preamplifiers and cable between all those elements is the benefit of active.

The experts in active where the first two players: Genelec and ATC. They’ve been after this idea with real commercially available product since early 80s.  Look to technical research and white papers written by both.

I'll second poster @fiesta75's first reply above. Active at its core is simply defined by having the cross-over placed prior to amplification and acting on signal level, instead of it receiving the output power from the amp on the receiving end between that and the drivers. This holds many advantages, like giving the amp(s) far better working conditions and effectively lessening their importance. This is what "matching" amps with all-in-one actives mostly comes down to, I find, as a means of economizing or down/up scaling each amp section to its respective driver segment (not to say there can't be a degree of SQ-matching with parameters involving damping factor, topology etc., but this opportunity goes for active-as-separates as well), rather than some fancy "they're a match made in heaven you won't find elsewhere." Marketing tactics, right? Or at least a modified truth that calls for the need of the reader to decipher "matching" and its possible meanings. 

Nothing dictates for active configuration to be a bundled solution, but as such would likely just be called an active speaker because it's a product ready for implementation with a source/preamp. That is, an active speaker simply points to being an actively configured plug-and-play product with the XO in some form prior to amplification as this principle dictates, whereas 'active configuration' just points to its basic principle as mentioned, which can be either a bundled or separate component solution. I use the latter solution.
I prefer the former but I’m not a DIY guy and I don’t want to fry a speaker using the wrong parameters. I know some have used different amps and tweaked the settings for JBL M2’s but setting up actives with DSP crossovers is more than simply picking what amp you like and randomly plugging numbers in the control engine.
Boy I must be living on a different planet. You guys are talking about having an active VS passive crossover. That has ZERO to do with active loudspeaker that have the amplifier/Amplifiers built into the speakers with electronics to provide not only the crossover but also to EQ the speaker. Sonos speakers are an example of "Active" loudspeakers. Active crossovers and bi or tri amping have been around for decades. Whether doing this is better than a well designed passive crossover is a toss up and depends on who you talk to. You are using passive loudspeakers. As long as the amps and crossovers are outboard the speakers are passive. If you think you can do better using an active crossover than the designer's passive crossover you might be sadly mistaken. 
Nope, not at all. You bypass the passive crossovers entirely. Eliminating resistances of the inductors and phase shift and delay of the caps. Solid wire between voice coils and amplifier outputs. You can still use you DSP for corrections if you like...
