Hi guys,
does anybody now of a design of a good sounding 6" guitar cab/amp for playing in the living room?
I have a small low wattage (0.5W) marshall style tube amp that would be perfect for that. Through a 12" speaker it sounds incredible. Through a 6" jensen alnico it sounds more bell like, with piercing highs and no low end.
Are there any tricks (like venting, bass reflex,...) that could be used to tame the highs of a 6" speaker and give it more bass response?
I find amazing how there are tiny bluetooth speakers with tons of bass, but not a single small-ish tube amp. If one neglects speaker distortion, would that be an option?
I would like to learn a bit more about acoustics to give it a try. Any suggestion where to start?

Here iare the parameters of the speaker (assuming it is the same one).

And what to do with them assuming the author got it right.

Thanks,
that is exactly the one I have. So bass reflex is in this case better than just a sealed box?

Well, after reading the document I obtained a box with 96l or 5870 cubic inch.
That is a little too big.
Guess I will have to dive deep into the models and learn a lot more. There is probably a way of having a trade off between size and bass response. Or use some passive/active systems to make this work for smaller enclosures.

Three cubic feet seems a little large. Rerun the calculations with a one cubic foot box, it should give you a hump in the bass though, not the end of the world. let us know what the system resonance frequency and the amount of hump is.

If he can spare a whole cubic foot, he may as well use a Twelve.
I have never been happy with small speakers pretending to make bass. They are lumpy, distort, etc. Even when not played at stadium levels. You can't fool Mother Nature.
IMHO it takes a Fifteen to deliver solid 50Hz, which indeed suggests a Twelve to do 82Hz.
Note that an acoustic guitar body, hammered round, is about 12 inches across. Your ear knows. E-guitarists use 1-15, 2-12, and 4-12 arrays to give the effect of a "BIG guitar". A Six is a small ukelele.

In a perfect world...
I saw some 6" guitar speakers in a surplus store here, thought about two on the desk top running stereo would be neat but I did not know how they sounded so I passed. Normally my Champ type amps have 10" speakers which I think are a noticeable improvement on the 8" drivers in them. I think a 12" might like a little more baffle area than a small cabinet provides.
After reading a little bit about it I discovered that most of the extra bass in bluetooth speakers come from passive radiators, extra speaker excursion and sound processing/EQ.
I want to avoid the complex part of signal processing and only apply some mechanical principles.
I never seen a guitar speaker with passive radiators and might give it a try.
I also found some thiele calculators to help me identify the ideal cabinet size and tuning

Well, it seems it is really difficult to calculate the parameters for a Qts of 0.99.
There is no way of achieving an acceptable Qtc, which should be around 0.7.
I will always have a weakly damped system, or am I wrong?
The eminence 620H has much better values in this case.

Those speakers are NOT suitable for any Thiele Small trickery, way too high Q for that.
Practical option is to put them in a small box, you decide on size based on your convenience but guess 40 x 40 x 30 cm would be tops, and wouldn´t be worried if all you can achieve is half that volume, you decide.
Speaker WILL have a bass hump, which will work to your advantage, don´t try to dampen or attenuate it, so little or no stuffing inside.
You ever saw a Marshall or Fender cabinet filled with fiberglass? .....
Me neither.
Never ever.
Ampeg yes, but they live in the Bass World and to boot Everett Hull came from the Hi Fi world, so ....
And that´s it, you´ll get whatever that little speaker can put out.
Killer little speaker.
