That would be amazing. Please let us know if you find such a thing.

 

minidsp 2x4 + some 4 channel amp

 

...or a salvaged PC power supply + MiniDSP 2X4 + 4-channel car amp lying around collecting dust.

 

In budget, is limited:
The only option off the top of my head is this:

Beocreate 4 channel amplifier | HiFiBerry

I guess there are US options available? Or maybe an importer. I doubt it is real "HiFi" grade though.

This is a higher end option, probably better to do justice to your hard work, and a very nice integration etc:

Hypex FusionAmp FA122 with on-board SMPS and DSP

The Hypex FA122 has two 125 Wrms Ncore® amplifiers which can be bridged to form one 250 Wrms amplifier. Output power: 4Ω: 2x 125W, 8Ω: 2x 75W

Good option at only $80 or so.

Worth remembering that all these small boards need something to program them. That Dayton needs a specific development board, the one I linked a RPi. Probably Sigma Studio knowledge as well (not sure if there is some easier options with the RPi)

I'd still 100% recommend those DSP plate amps though. Actual DSP UI, PSU built in, great quality Class D amps, neat mounting, SPDIf in and speaker link.

 

There's been discussion for a long time about how to use an AVR with multiple channels in an active setup but it always comes back to using either analog inputs with an external xover or separates with rack mount pro gear (my preference.)

Hackable AVR For Active Speakers?

Does anyone know of any AVRs that are capable of being modified to use as an active crossover and amplifier? Here's what I want: a single box with a digital input and 6x or 8x amplifier outputs with individual DSP per-channel. I was thinking that AVRs have all of the components you'd need for...

I do this with a Denon 7.1 AVR and a Dayton DSP-408 and it works great, Denon and Yamaha AVR's pre HDMI with EXT. IN

 

thank you all

 

I guess they added some 4 channel options.

this is looking doable... 4100, dspb-icp1, their power supply, then just whack it all on an aluminum sheet, use laptop to tune, and viola, cheap, powerful, active 2-way stereo set up?

 

Just use a converter and car audio amps it’s a better deal and good enough.this is what I am doing with my home audio floor standing setup one day of course 7.1 Dolby atmos

 

I would not recommend this setup for a number of reasons: major lobing issues in your midrange and midbass, dispersion pattern will be very narrow, with a 24 and 12 on the bottom your tweeter will be no where near ear level, and you'll need 10 channels of amplification (assuming the 6.5 and 4's are wired together) just for a stereo pair. There are many proven Hifi and HT tower designs out there that can be built active or passive that would yield much better results for much less time, effort, and cost.

If you're just after building something that looks crazy and gets super loud than build away, but if you want something with decent sound quality I'd look elsewhere.

 

waste of time imo

 

to the tread or the most recent posts?

 

ok, whats your suggestion then?
