I'm looking for a small decent sounding single way or two way powered speaker that only has an aux input and volume control with no wireless connectivity of any kind, no battery and no remote control at a reasonable cost maybe around $100 or under.
I do not expect 20Hz bass, but I would like the bass response to be at least no more than -3dB down at 60Hz if not better than that.
Cabinet size should be no bigger than:
10" W
10" L
10" H
What single speaker would be recommended?
I can also install a pot in a box as a volume control if a recommended speaker does not have a built i control.

I'd prefer staying away from computer speakers as they are usually in pairs and I only need one. Plus the quality of them is all over the place and most won't go down to 60Hz.
Your bass response/size requirements may be difficult to satisfy.
Perhaps, but I'm sure there's something out there somewhere.
Even if it's a passive speaker that I have to add a chip amp to that will be fine.

That opens up your choice options a lot. There are many decent, cheap used speaker systems around too,
especially if you live near a larger city. Recently I saw a pair of EPI-100s for $35. Check your local Craigslist.

Given your budget, that's probably the only route. Class D amp + laptop power supply.
Yup. Thrift stores, FB marketplace etc.

Well I may have found something in my stash.
https://www.parts-express.com/Aura-...ne-Neodymium-Magnet-Woofer-299-030?quantity=1
Here's the specs of the woofer in the following open back box
12 1/4" H
10" W
7 1/2" D
5/16" thick
The box also has a 2" cone tweeter.
I did a test with an audio generator and I hear output at 60Hz.
So it looks like I may try a temporary crossover just to see how good the speaker sounds.
If it's good enough I'll get a chip amp kit from Qkits and have me a decent enough speaker for under $50.

If I could find one in the USA, I might get it.
Here's the temporary crossover for the speaker.
I do intend to build a full 12dB/octave crossover if I like how the speaker sounds.

At the moment if I need a pad, it will not need much of a pad. What I may do is put a 1 ohm resistor in series with the tweeter and see how that works.
If the balance sounds better then I'll calculate the 12dB/octave crossover adding the 1 ohm resistor to the tweeter impedance.
Here's the measurements of the whole speaker.
Without zobel.
With zobel. Calculator called for 6.7uF and 7.1 ohms. What I had 7.5 ohms and 6.2uF. Now the woofer was measured int he box itself so the numbers for it may not be 100% correct which would throw off the zobel.
May test just the woofer out of the box tomorrow afternoon.

Visaton B200, whoops, Sorry, I missed the $100 requirement.
Save a lot of money and get the Visaton BG20. Put it in a sealed box, really easy. There is room to put your amp in there, and it’s plenty loud too. https://www.parts-express.com/Visat...-Speaker-with-Whizzer-Cone-292-548?quantity=1
MarkAudio CHR120 might actually get you down to 60hz in a box of that size. Again, very simple and sounds really great. It’s right at $100, and you don’t have to buy the pink one. https://www.madisoundspeakerstore.c...io-chr-120-champagne-6-metal-cone-full-range/
There are far too many two way speakers fitting your description. We need to narrow the options down a bit. Could you tell us what it’s for, it’s intended use, then we could give you better recommendations.

Nice.
The idea for the speaker is to reproduce music. Given it's moreso for work, I am not really concerned about the sound quality so long as it's reasonably flat from 60-16kHz.
The speaker will be moved around as well.

The BG20 is good but the upper range isn't the most convincing. If you add a (super-) tweeter that's a punchy speaker. I think it wants a bigger box though, even sealed. Excellent price/performance.
A better fit would be the Sica LP165.38/426 TK ER / Sica Z004002 (yes, they got two model names) or the Sica Z004003, which is the 4 Ohm version. It fits in the dimensions even with BR. Huge VC, 38mm.

OP's constraints give 11 liters of net volume with a 15mm thick enclosure. How on earth would response down to 60Hz be difficult to satisfy with that? I have 2 liter enclosures playing down to 30Hz in room 😅
You can pick pretty much any cheap midwoofer/tweeter combo from a reputable manufacturer and fulfill your requirements so far

Here's the actual crossover I'll use.
Haven't filled in the values for the zobel yet.
The 1 ohm resistor did make the tweeter more balanced with the woofer.

I remembered that I have a Boston Acoustics LCAI220 amplifier.
https://www.crutchfield.com/S-FmvQqOKTqX7/p_065LCAI220/Boston-Acoustics-LCAi220.html
So I tried that with the speaker and it works well. Plus since I have another identical cabinet, if I can find another identical woofer (cannot remember if I bought two when I wanted to re-do these speakers several years ago), I can have a pair of stereo speakers.
I also decided to try a dome tweeter I had and it sounds better with the woofer.
Here's the completed crossover.

The parts should be here today.
Instead of gluing the coils and caps down, I'll place the components then drill holes on the board so that I can use nylon cable ties. Given the board, I'll have to solder them in at work given my soldering iron at home isn't strong enough.

Got the speaker done today.
As seen by the graph, I goofed with something.
I accidentally reversed the coil values when I put them on.
Will have to fix tomorrow.
