Help for a cheap 2.1 computer setup (need a pre-processor/amp/something)

I havent' bought A/V equipment in a few years, so I'm out of touch with what's available these days. For working at my home desk (much more frequent these days!) I have 2 desktop speakers and a 10" powered subwoofer. Just because I had them available, I was powering the system with an Emotiva LMC-1 prepro and a pair of Outlaw monoblocks.

Well, the Emotiva PrePro died so I'm looking for something cheap to replace it with (these are not high-end bookshelf speakers). What are my options these days? I see a lot of 2-channel Class D amps that would take an RCA input from the computer, but they all seem to lack a subwoofer output. Is there some inexpensive 2.1 solution out there?

I’d like to tag along if ok. I have a 12x12 office with a full length built in desk, 32” deep (see pic). There is a large cutout for legs so I could easily put a sub under there if it’s too cluttered on desk.
I am also looking for a receiver that can have an input for my Mac and also pic up Bluetooth from my phone. That’s about all. But I’d like to have some decent power to run the bookshelf speakers. Thinking NHT Superzero, Polk S10, Q3010i, etc for speakers. No clue on the sub yet and whether or not the sub should be powered.
Most of the mini receivers have much more functionality than I need.

Looking at the Fosi Amp. Bluetooth and one set of inputs $70.00

BT20A Bluetooth 4.2 Stereo Audio 2 Channel Amplifier Receiver Mini Hi-Fi Class D Integrated Amp 2.0CH for Home Speakers 100W x 2 with Bass and Treble Control TPA3116 (with Power Supply)

Micca OriGain $99.00

Micca OriGain Compact Stereo Integrated Amplifier and DAC, 50W x 2, 96kHz/24-Bit, USB and Optical S/PDIF (Black)

Although I’m not sure those are the best options. My two inputs are Bluetooth, the computer and outputs need to be the two speakers and sub.

Thanks for letting me tag along.

There are a number of inexpensive compact stereo amps with a line-level subwoofer output. I'm not sure that any of them have crossovers, though. (Full range signals would be sent to the speakers. The signals would be summed to mono and passed, still full range, to the sub.)

It's too bad that the audio drivers for a PC never seem to support a 2.1 output. (5.1 or 7.1, yes.)
