CKehoe Posted June 29, 2020 Share Posted June 29, 2020 Bryston's approach to active speakers seems to be wasteful and completely behind the times - big metal boxes with expensive heat sinking and A/D/A processing (meaning D/A/D/A for those of us who are primarily focused digitally stored music. However, the approach the preamp/crossover/amp combos outside of the speaker boxes offers great flexibility and opens up myriad potential upgrade paths. One could start with a simple 2 or three way system, with a capable multichannel digital crossover/preamp, and over time, independently upgrade: 1) speakers ; 2) crossovers; 3) digital filters; 4) D/A conversion; 5) preamplification; and 6) amplification. Of course, many of these functions might be combined (crossover + digital filters in and HQ player server, or Exasound 8 channel DAC straight to amplifiers, for example). I am intrigued by the possibility of just such a sytem, but the interesting question to me is "what passive speakers" would I want to try this out on, i.e., who has a great box and great divers with an OK, not great crossover?

Kal Rubinson Posted June 29, 2020 Share Posted June 29, 2020 It is relatively easy to do with JRMC (which has built-in tools for channel processing, DSP and VST plug-ins) or Roon (lacks plug-ins) and a multichannel DAC. No preamp needed except for personal convenience. OTOH, it is hard to find a finished speaker without a crossover so your options are to build one (many good kit projects out there) or buy a good speaker and remove the crossover. In terms of asset management, perhaps a used pair would be the way to go. Kal Rubinson Senior Contributing Editor, Stereophile Link to comment
KindaHz Posted July 6, 2020 Share Posted July 6, 2020 A budget DIY idea that caught my eye was to utilize a miniDSP ICE250 plate amp in each cab. Those who have completed active cab builds seem to like the flexibility and quality of power at their given price point. I'm a little in love with idea of going this route so I have started a fair amount of research to hopefully launch a build soon.

CKehoe Posted July 6, 2020 Author Share Posted July 6, 2020 Looked at that, and the NCORE plate amps, but kind of don't want to build cabinets. Link to comment

I get it...sans knockdown cab kits, the build process with custom cabs requires time, more tools and dedication to maintain a high level of production detail. It's a task, for sure.

CKehoe Posted July 9, 2020 Author Share Posted July 9, 2020 I'm thinking of maybe picking up some Vandersteens 2Ces or 3As as mules for this project. I've had Vandy's before, and liked them, so I could use them normally untill I was ready to modify them. The drivers are supposed to be capable well beyond their crossover points, based on their use in 1st order crossovers. But they are 4 ways - meaning 8 channels of amplification! Link to comment
CKehoe Posted July 9, 2020 Author Share Posted July 9, 2020 My other thought is a set of KEF Q series towers, but I sort of like the idea of a sealed speaker for my test case. Link to comment
