Speaker problem
monkey puzzle:
I have a pair of standard Dell PC stereo speakers that I thought were plenty loud enough for my mame cab. I broke the cases open with the intention of mounting the actual speaker parts in my speaker shelf. Before drilling any holes in the speaker shelf I tried the speakers without their cases. To my suprise the speakers sound awful without the case. I assume the cases are need for acoustics etc.
I was wondering what the speakers would sound like once fitted to my cabinet. Would they sound ok, or would I need to build a small box around the back of them? Or would it just be best for me to buy a new set of speakers that I can fit without de-casing?
compute:
Since they're already out of the case, I think it would be worth mounting the speakers in the cab and giving it a shot. Depending on where/how you mount the speakers, the cabinet may provide the covering you need for the speakers to work well. Neither of my cabinets have any cover over the back end of the speaker.

Worst case can you glue the back of your speakers over the speakers when they are mounted in your cab? Speaker mounted with back enclosure upper left of picture.

It's a bit late for that now. I had to destroy the cases just to get into them. And then I threw the broken parts away.
Not sure if I should try mounting the speakers if there is a chance they are not ok. The holes might not be correct for the speakers I end up using if these ones are no good.

Sometimes speakers are very optimized to their container air volumes.
However, sometimes the makers opt for smaller package design, so they are not fully optimized. Such was the case when I actually improved my Pc speakers, by making my own wooden boxes for them.
Many of them also have Bass Ports. Holes specifically designed to create a certain tone when air flows out of it. You can sometimes remount the port, but you dont always need it. In my case, I left the rear of my speakers open-backed, as that sounded best.
When I rebuilt my speakers, I used several oversized pieces of wood, and moved them around, holding them in place while playing audio to find the best air volume and thus best sound output. Then I marked and cut them to spec.
When mounting them in a huge wooden box like an arcade cabinet, the entire cabinet becomes a speaker. It can amplify the speakers effect. So even though your speakers dont sound right to you unboxed... they will probably sound really nice in the arcade cabinet. And if somehow it doesnt, you can add your own back box with roughly the same air volume of the originals.
