EUR 688,00 per pair.

You are correct. Seems very good value.

The minidsp modules are not the last word in SQ due to their ADC and DAC components. If you go down this route, and assuming that you are using a digital source, think about the nanoDIGI (also miniDSP) which requires a seperate DAC after it. One per stereo channel! The Twisted Pear Buffallo III is very well regarded and will handle four stereo pairs. You would need a Twisted Pear IVY stage per stereo pair. And obviously power amp units per channel. For power amps look at 41Hz kits, Hypex UCD180, or modules from classdaudio.com. All of these are very popular, and offer excellent results for the investment.

Frankly, if you choose to go down the active dsp route, then you can design you own speaker with any drivers you want, in any configuration you want, and be confident of getting the result that you are looking for. So long as drivers are given suitably sized chambers, it would be hard to go wrong.

Are Hypex selling their DSP modules yet?

Might make sense going with them if you are already using their amps.
Personally I haven't tried them so can't say anything about the quality of Hypex' conversion.
Or just use one of their plate amps with the DSP built in.
 
After a bit of reading in Minidsp I understand most of the time they are used directly out of the source (cd player etc). As the user above stated doing ADC then DAC will have lost some quality. Will this be noticeable? The reason I ask is I would have to run from 7.1 outs on my RSP-1068 and between my amps. The RSP is my switch for multiple sources so I cannot bypass it and in addition for things like blu-ray, etc I want multi-channel out.

It's great to hear though that having a DSP acting as a digital crossover significantly helps merging a driver combination.

That's a bit of an exaggeration, don't you think? You want to be starting from something where the drivers all have good performance and sufficient maximum output in bands that will work reasonably well with the dispersion and baffle spacing of each driver. No fixing any of that with DSP. The main thing DSP gets you (short of fancy FIR experiments and that sort of thing) is free crossover revisions, and access to filters that are only practical at line level. That's a huge plus, but not a panacea.
 
See my post on testing the wrong way as it relates to driver cost and results. Simple, but a view.

On active speakers, could it be at an active speaker of sufficient quality just won't package well? I mean, try to put a serious quality amp in a 17L monitor speaker.
 
I have yet to hear an active speaker worthwhile , so yes a big stretch , seeing no one has gotten it right yet ...🙂

I on the other hand have yet to come across a worthwhile passive speaker or one that could not be improved by running active.

Dynaudio does or at least used to sell the BM5 active or passive.
In a direct comparison the passive was very much inferior to my ears.
Others had the same experience with otherwise identical ATCs but they were a bit beyond my price range.
 
Well, everything is a compromise isn't it?

If you have to spend more money on new amps of a quality equal to what you already own for each 'way' in your speaker, plus the active components themselves, then that means you have *less* money to spend for better quality drivers.

So, higher quality drivers with passive xo's or poorer quality drivers with active xo's?

Personally, I would think that if the OP found the S8's to be very much to his liking with passive xo's, then building a similar diy system with much better drivers but still with passive xo's will be more than satisfactory. And simpler too.
 
The cost of high-quality passive crossover components is far from trivial.

If you are prepared to buy s/h or able to build your own amps the difference in cost is not that great at all when using the same drivers.

There is also an inevitable insertion loss with passive crossovers so to reach the same SPL levels a passive design will need a much bigger amp than an active design.
