Dear all, being new here on this forum I thought I start my little thread here, topic see above.
Feel free to ask, criticise, comment, whatever - I'm very open to new ideas.
Please keep in mind I'm keen on walking unpaved roads too and also willing to go for the extra mile just to achieve something 'crazy' - which might be stellar at the end or a horrible something. Doesn't matter. DIY is all about building fun, apart from a hopefully good end-result.
- Source: RPi4 + Volumio + HDMI I2S out, DAC not decided yet. Due to good results and missing number fetishes I consider a MiniDSP solution too (no separate active XO then, it will be implemented with the MiniDSP module)
- Crossover: 2x mono 4th order active 3-way Linkwitz-Riley (Elliott Sound Products' website seems to be down, don't know where to source 2 high quality assembled boards.. XLR in, XLR out)
- Bass amps: 2x Hypex UcD2k-based Class D monoblocks, powered by DIY toroidal linear PSUs
- Midrange amps: 2x parallel pushpull Class AB tube monoblocks (KT88-KT150) if output power need allows. If not, switching to Mosfet design
- Tweeter amps: 2x pushpull Class AB Mosfet monoblocks
- Bass driver (1 side): 1x RCF LF21X451
- Mid drivers (1 side): 4x Faital 6FE100
- Tweeter (1 side): Aurum Cantus AST25120
- separate boxes, experimenting with concrete or screed (midrange and tweeter boxes will be transportable when moving, bass box fixed and have to be smashed and reconstructed with each move - but I don't intend to move the hi-fi very much )
- whole chain XLR based, fully balanced amp topologies, with the strategy of longer XLR interconnects and amps possibly closer to speakers with somewhat shorter speaker wires - at least for bass definitely (amps just behind the bass speakers)
- independent holder for bass/midrange/tweeter boxes, no physical connection between them (still on top of eachother but via lightweight chromed steel frames or floating on neod. magnets if I can manage a good balance with them)
