Well, I tested the Tamiya Speakers in several combinations possible. At least the king tiger, the Panzer IV, the KV1 which is the same but in green and the Sherman.
The PIV is a small tank. When you fit the Elmod, a decent battery and the speaker, there is almost no space for anything else so I tried the speaker with no resonance box and the sound quality dropped dramatically. I also did quite a lot of tests with speakers and the benedini boards and also with my bluetooth gadget, and what I can tell you is the resonance box was a must. I dont know if you have super quality speakers, that might be the case, but all the ones I tested (about 15) needed the resonance box. Even if it is just a peanuts can like the one showed in my benedini review. Maybe a huge box is a no go with the speaker, but sometime ago I read somewhere how the sound waves work, and it seems if there is no box, he sound waves that go from the top of the speaker are neutralized with the ones that go from the bottom. My opinion is it was true. And also all my tests say no box, no bass.

Anyway I ended using the stock panzer IV box, but I had to drill it and insert one conduct to be able to use the smoke machine. But again, very tight fit.

Out of the Box the Tamiya Speakers the best and expensive you can get.
Ask a Hifi-Entusiast, a Speaker need a Box with a rated Volume for good Sound - Tamiya do that.
The most Speakers which are provided whit the HL-Tank are crap - because the little Speakerbox have no Volume.
The Taigen-Speaker ist a good Speaker too - put them in a Box of 10x10x6cm and wonder how good this Thing sounds...

The size of the box depends on the type of sound required - long, deep bass or shorter punchy bass? Then you have the options of ported vs non-ported/sealed boxes - again related to the type of sound required. Also, you need to take into consideration the make and type of speaker - some have a greater throw than others (they move further) - this is another factor to be considered when chosing enclosures!

In short, speaker/enclosure choice can be an in-depth scientific study and isn't always a simple matter - ask the boys who do SPL Competitions

Not forgetting that you need to find a mounting place that is solid and not going to cause vibration in the hull and that the cone should be free to shoot the quality sound out of the hull with a clear path or all that effort finding the right unit will be wasted!

I've often wondered why some folk want a boot full of ear-splitting speakers, and flashing lights. That's a world where dB rules. Studio speakers have an accurate flat response, where Hi-Fi speakers are designed to offer deeper bass, and crystal top end, supposedly because that's what turns audio enthusiasts on.
You're right though, speakers come in many forms, with many features, for many applications- from ear pods to Marshall Amps. Then there were the hush-hush military ones, I believe, designed to make people sick..
A good enclosure is crucial for shaping the sound, but the speaker has to have a good frequency response, and a progressive action.
I've often thought the wee loudspeakers in my Harmon Kardon Sound Sticks, or the speakers in my old iMac would make a great basis for tank acoustics, given the right enclosures.

Hi, now you mention me... You all know I am very critic with Tamiya... But I must say the speakers are good, very good. But I don't think this is because of the quality of the speaker itself. They are good because of the resonance box. The bigger the box, the better the sound and better the bass.

Yup, it's the enclosure that makes all the difference, and having a tuned bass slot. The Visaton 2.5" speakers are top notch (just make sure that you get the right one, eg 4ohm/8ohm for whatever board it is). The Tamiya ones are also top quality...but at a price. Visaton manufacture hi-fi speakers, they have an excellent reputation.

For big HiFi speaker boxes/enclosures, something dense like MDF or a good quality plywood at 3/4 inch thick is best.
That's probably a bit too thick for our tanks, but you can get 1/4 inch, and even 1/8 inch thick MDF if anyone wants to make their own boxes.

I’ve been making bass boxes & installing car hifi systems for years.
Studio monitors are indeed fantastic, but their price relates directly to the quality of the speakers they house. They are designed for crystal clear mids & highs only, they should be used in conjunction with a separate bass enclosure.
In the car hifi world the precious frequency that everyone wants to hit is 33hz, apparently this is the frequency that ladies genitalia resonate...
Sorry I digress lol
Our tanks are only tiny so the boxes the speakers need to go in are also tiny, so we are limited on what we can achieve.
Ported or slotted boxes are tuned to boost the performance of the speaker at a specific frequency (33hz?) or over a narrow band of frequencies, ie 20-100hz. You just wouldn’t use this method for a “full range” speaker, ever.
A port or slot in a full range speaker is the equivalent of a stripe on your car, it makes it look sportier but actually does nothing for performance.
My ultimate advice is to buy the biggest decent quality speaker that is rated at least double the rms wattage of the power you’re going to put through it, then make a box to fit your tank out of plasticard, mdf, ply, or whatever you have lying around, of a decent thickness to avoid it vibrating, internal braces are fine, I 3D print mine. Then stuff the box with fluffy wadding or cotton wool, then fit the speaker. It’s important that the box is totally sealed everywhere or farting noises may occur.
4ohm car speakers are probably best to use as the Visaton ones are quite feeble.

Now, I had a good hoot at that one,Wayne I really must invest in a bass speaker capable of 33hz. Then.....
I can only imagine that said genitalia would look something like this (but, for the sake of propriety, represented by mandible lips...

More like this really, just look at the expression on her face when the bass kicks in
