A little update. I placed the Daytons in my radio today and there's a big difference with the original speaker. The bass goes lower, the midrange has opened up quite a bit and the highs are smoother. The difference in sensitivity is also very noticeable. It wasn't a literal drop in replacement though. I had to enlarge the mounting holes from 4 to 6mm and because I didn't have any self tapping screws lying around with a big enough head I used washers.
But I'm not there yet. I feel I can get more out of the Daytons. I'm going to experiment with separating the speakers from the rest of the housing with panels. I have make them fit perfectly but hey, I'm a shipwright, that's no problem for me. I should be able to get around 2.5 litres for both speakers. Also want to see what a bass port in the bottom does. I can always close it back up again if it doesn't work. Any suggestions on the size for a bass port?

Make a new body, like a sound bar, or vertical, with angled speakers.
Use the current electronics, or build a new set, FM/USB module and an amplifier matching the speakers and supply.

For 3" speakers, a 1" or even 3/4" round bass port should be sufficient in size.
Think about putting them at the sides...

That radio with 2 speakers is about $8 here, and loud enough for regular background use.
Must be about 5 to 6 Watts total sound power.
Mains and rechargeable battery types are sold.
$6 for a mono version.

Obtain some 28 mm ID (32 mm OD) PVC pipe.
Given an estimated enclosure volume of 2.5 litres, a traditional reflex tuning can be achieved using a 45 mm length of 28 mm ID pipe.
It would be worthwhile experimenting with pipe lengths that are incrementally 5 mm above and below that value.
Use the the length that gives the best audible resullts to your ears.
The only viable position for a bass pipe is in the bottom. I'll have to make a flange and attach it to the pipe so I can screw it in place. Luckily we have a lathe at work.
Here's how the radio sounds with the Daytons and no further modifications. I recorded it with my Galaxy Tab 10 and the mic isn't the greatest. The sound is fuller in real life.
No, I did not specify pipe length.
Our speaker makers here make ports by making holes in the front or sides of the cabinet.
No pipes, just a decorative flange, but yes about 40 to 50 mm long.
Ready made molded part, looks like a flange attached to a bit of pipe.
They just drill the hole and push it in place.
I have never (in my limited experience), seen stuffing and bracing either.
When I read about those here on this site, I think that you pay a lot of attention, here in India nobody seems to bother.

You can cut the pipe and use some sort of reducer to make the port, lathe may not be needed.
Something like the bit used in the bottom of kitchen or bathroom basins should work.
Stick a bit of pipe...

I'm sure, Lemwise, as a professional shipwright you know all about portholes! 😀
P.S. Even given the limitations of the recording, the sound comes over as excellent for a portable device.

It's starting to get better even though the Daytons aren't fully broken in. I think it's better to wait a week or two and see if it improves more. And I don't really need the bass to go much deeper because it can overwhelm the rest of the spectrum when I have it playing in a boat.
I agree you should wait. The performance using the port that I calculated using traditional methods is unpredictable and very likely to be inferior to that of the sealed enclosure.
I only offered the suggestion since you said you were prepared to close the port up again if it didn't work.
P.S. For future reference, putting those Daytons in a larger enclosure would not necessarily make them sound better.
In fact, too large an enclosure can weaken the bass. There are optimum sealed and ported volumes for those Daytons which are arrived at through the use of loudspeaker design software which takes into account the driver parameters and the required bass quality and extension.
Look into this aspect of loudspeaker design and then you could apply your advanced woodworking skills to making a fantastic pair of speakers for your home.

Please Naresh, suggest you do a little searching (Google is your friend) before making such statements (like when you suggested a junkyard car woofer to replace a $350 103dB 400W RMS Pro speaker a week ago), I shudder thinking at the $8 radio you suggest.
FWIW OP´s Work Radio is

Does your $8 radio match:
WLAN Internet radio
With a WLAN Internet radio, you can thousands of local, national and international radio stations in clear latest stereo quality receive - without the limitations of the conventional radio reception. With the unique "Radio zap-function" of the audisse-modelle change you through your 40 favorite stations in search of good music. In addition to the Internet radio function via WLAN receives the Audisse Shokunin all DAB+ and FM radio stations.
Hands-free operation
Proceed normally with dirty hands or with working gloves to your mobile phone in your trouser pocket? No problem. A press of the button in your work radio and enables you to telephone hands-free via the built-in microphone and speakers, just as in your car. (it links to your phone)
An output power of 2 x 15 Watt, a highly efficient amplifier the D class, DSP (Digital Sound Processing) and the unique audisse dual neodymium speaker enable a previously unusual audio experience. (I suspect the original speakers were pulled and replaced by those cheapies)
A robust roll basket construction. Rain, dust and dirt-resistant with protection class IP65. Impact-proof. ABS plastic housing. Flexible antenna 3 m long neoprene cable. Tüv/GS certification.
Operation via Undok App
The UNDOK-app on your smartphone or tablet can perform all of the functions of the Audisse Shokunin used without any problem.
Highlights & Details
- WLAN radio construction sites
- DAB+/FM
- Spotify Connect
- Network & USB media player

Just the single button (which can be operated with dirty hands or gloves or (I presume) an elbow) to hands free answer your phone is worth the price, go figure.
Again, I am impressed by it.
A link to the radio was given in the very first post (so no need to google) and I was immediately impressed by it. Far from being a toy!
Lemwise bought his at auction - and you're correct JMF - the seller obviously removed the original speakers and substituted the inexpensive 5W Creative ones!

Correction: Instead of "the seller" please substitute "someone", as the seller may be blameless!
The original speakers are the Creative speakers, a tech at PerfectPro confirmed this. They literally were an afterthought. Creative actually used them in the Inspire T10. The Daytons are much better.
Btw, Audisse was marketed by PerfectPro as their premium brand.

Strange, your PerfectPro link in post #1 mentions 15W as the power rating of its neodymium speaker and not the 5W clearly stamped on the Creative speaker.
A touch of "creative" marketing perhaps, as I would have thought the speaker should at least match the 15W power rating of the amplifier.
