yep, my search for 8 ohm sub woofer begins, but for now I do have 4 speakers that the FS is below 30 (one pair is 20hz)

What about something like the TK2050 board from Hifimediy (LINK) and just using 3 channels? It also leaves the 4th channel open if you wanted to use stereo subs.

Nice board I may have to buy one in a few months when the quest for power arrives

The hifimediy looks great, only a few problems/limitations to be exactly what I'm looking for.

1) Price
2) no analog in?
3) no sub xover?

I suppose it all depends on the final use. I think the original poster mentioned that he had one spare sub and some satellites. For computer or home theater where a coax digital or optical is available that might just be the ticket. If I was starting from scratch I think I'd go miniDSP to the 4-channel HifiMeDiy and have stereo woofers. Massively configurable and the amplifier is a known performer.

miniDSP costs as much as the amp :-(

that solution would be completed around $300 which is comparable to the price of ready made amp of the same specs.

I think that the depth of settings on the miniDSP can't be underestimated, also the ease with which they can be applied. Having an active XO versus whatever is built into the Ebay board makes mixing components MUCH easier.

All that said, that one TPA3123 on eBay is VERY tempting at that price. I suppose it might come down the components being connect.

You're talking about the TPA3123 2.1 board from XY, right? There is also one from Yuanjing, i'm unsure how good it is.

TPA3123 2.1 25W+25W+50WSUB amplifier board YJ-in Amplifier from Consumer Electronics on Aliexpress.com

What power supply would you recommend to use this with?
PS: I wonder whether this has an xover somewhere.
