I bet those speakers sound 'fast'.

The "baffle" (tire sidewall) is not very stiff, so I'd suspect smeared bass from them.

But they WILL channel the water in your carpet so you don't hydroplane.

Might be a good choice for my basement then…

Ok, since no one else stepped up ... I'll be that guy!

First off: That's a Yoko studless, snow tire. I would imagine the critical side-wall is stiff as F!
Secondly: I find it more intriguing and not so much funny, in concept. Why? Because we can't see the back and it very well may be open.
Thirdly: You can't judge what you can't see - meaning - unless some of you guys actually scored X-ray specs from the back of a Mad magazine (way back when... LOL), no one can judge what - if any - bracing has been introduced inside.
Lastly: How the driver is 'crossed over' would be pretty important. No?

(all of this assumes this was an actual proof of concept and not just a conversation piece... of course)

Open back designs can work - just saying...

And as always -- Don't flame, taze or tariff me .. Bro!



I now return you to your regularly scheduled, programming........

Generally no crossover needed with a single driver. It’ll roll itself off.

No exactly true. My bad for not being articulate. A single driver, notch cross-over could help with matching compliance between the drive and the greater structure.

A few more words...

IF it's a full range driver you don't need to cross it...that does not appear to be full range...

It's just not going to reproduce above a certain frequency. I guess a filter would keep HF out of it but other than some voice coil heat I don't think it would be a problem for that big speaker..

A tweeter, on the other hand, for sure needs protection. But that can be an incandescent light bulb...

I think the preponderance of discussions regarding notch and pass-filters tend to address more standard applications (cabinets and such...) & not something as esoteric as a tire. That said, low-order notching doesn't exclude applicability in the realm of tackling resonances, weird-ass harmonics or strange behaviors that deter from achieving 'flatness' in terms of frequency response.

If I had a big-ass garage, I'd think it would be cool to have a pair of those looking all road-worthy; assuming they do the job and do it well enough.

All-in-all, an interesting 'tread' lightly topic for discussion ...
