Want to replace the speakers in my work radio. Need some help between two choices.

Hey guys, I'm new here. So I bought an Audisse Shokunin work radio on a Dutch auction site. The price was pretty good so good stuff. Because the warranty has already elapsed I took a look inside and the electronics are quite good... for a work radio. The speakers though are something else, cheapo Creative 5 watt RMS "full range" speakers. It's pretty clear they skimped on those. Funny thing is this thing sounds better than other work radios. Anyway, no more warranty so I can stuff in it what I want. I found the Dayton Audio DMA80-8 and the Visaton FRS 8 M. The Dayton is literally a drop in replacement but more expensive, the Visaton will need some minor adjustments. The price isn't an issue. The radio casing is 245mm wide, 150mm deep and 170mm high with a D-class amp, control board and usb/bluetooth board in it. This takes up a good 60% of space of the back half of the radio. Any thoughts on which would be better in this case?

This is the same radio. The Audisse brand was made obsolete and the radio was rebranded as the Rockpro: https://www.perfectpro.eu/product/rockpro-rp2/

What's inside it now 😛

Hi and welcome to the forum!

I see that the Dayton Audio DMA80-8 is a 3" speaker.

Just one of the factors you should consider is the speaker sensitivity.

Choose a replacement with a lower sensitivity than the original and your radio won't play so loud.

The Dayton's sensitivity is 85.3 dB, but the Visaton's is higher at 88 dB.

I can't imagine the original 5 watt rms Creative speakers have a higher sensitive than the Dayton or the Visaton. Besides that, I'm not interested in playing very loud. I'm a shipwright and I make interiors on steel boats. That means the space I work is limited and filling that limited space with loud music is very distracting. I'd rather have speakers that are well balanced and not overly present.

I would just get whatever drop in replacement looks good to you, that way you can still use the old speaker without a bunch of screwing around, if you find that it sounds better than whatever you buy.

edit: oh the visaton is a paper cone, I'd get the dayton (of those two) for a work radio as it will be water resistant.

That must be a challenging acoustic environment for any speaker!

Your link shows the jobsite radio to have two speakers (for stereo).

Do the two speakers share the same sealed space (i.e. not a vented space) within the main enclosure and, if so, what is its volume?

The sound always sucks until the insulation is placed. And yes, the two speakers share the same space.

I already decided to try the Daytons first because it won't require me to mess around with the holes for the speakers.

A test result I've seen on the Dayton DMA80 (4 ohm version) show it being used in a sealed enclosure of volume 38 cubic inches (0.62 litre).

This enclosure gives an F3 frequency of 112 Hz (F6 = 129 Hz).

My calculation shows the volume of this radio is roughly 6.2 litres. A bit less actually because the control panel on top slopes down at an angle. It's probably more like 6 litres but that's shared by two speakers and the electronics. Still, the Daytons should be a clear improvement over the Creative speakers.

Something dawned on me when I was taking a shower. I could of course just strip all the electronics out, make a proper enclosure and re-use the whole lot. I could make it so the electronics are separate from the speakers and it would allow me to use even better quality full range drivers matched to a good volume.
