Oh, what did you do that for!? I have enough trouble watching junk on PooTube without people suggesting more of it. Oh well, another rabbit hole to fall down.
Mark,
You should get a 'reasonable' bass out of the 6 inch speaker. I don't know but I suspect that is what's in the Lexus and it sounds 'fine'.
I guess the question here is what do you want? In what way do you feel the current set up is deficient?
Like mk2cossie says, you may be able to get what you want by getting a decent amp (if you don't already) and an EQ so you can set it up.
If you want that thump of a kick drum then, personally, I'd suggest go big and hide it. You are more likely to have success that way than trying to do something clever with small stuff.
That said, I put a silly speaker in a tiny bit of wood and it seems to work. I don't understand how. I think it's got so much power available that it just grabs common sense by the neck and headbutts it into submission.
A couple of things to bear in mind.
Those tiny speakers in your TV probably have a very well designed cabinet behind them to get the best out of them. You won't be doing that unless you are very clever indeed.
Secondly your living room is a quiet well damped place. A car isn't and your car definitely isn't. If you put your TV in your car you'd probably find it struggled.
To make matters worse you have to overcome the natural bass noise of the car. Any bass set up that sounds natural in a moving car normally sounds over emphasised with the engine off.
And lastly, what do you listen to?
Katy Perry or Dua Lipa have truck loads of really low bass that really wake the MR2 up. But play some Genesis from the late 70's or early 80's and there is none. And they are a prog rock band for goodness sake. You may be looking for something that isn't there in the first place.
Why is there no bass in older recordings? The way it was explained it me was that if you tried to have lots of bass it would just cause the disc cutter to skip into the next grove when trying to cut the master record. So music was mixed with that in mind. It was one of the purposes of the RIAA curve used on vinyl. It took all the bass out of the recording so they could get the tracks closer together. Or so I believe.
Once you move to digital recording and reproduction none of that matters and you can have as much bass as you want so tastes have changed over the last couple of decades.
And lastly, lastly... If you tweak your hifi's eq you can make one record sound great, but another will sound curse word. (especially if you have 7 or 9 bands to play with.) So you tweak again and keep going iteratively. Eventually you'll find settings where most things sound lovely. If you can't get to that point then something is probably wrong. Listen to the human voice on it too. You are very used to listening to people speaking and it'll stick out like a sore thumb if somethings wrong in the mid ranges. Beware though because a lot of radio stations process their mics horribly and there is no chance on Gods green earth that they will ever sound natural.
I have to admit that when I do the iterative fiddling process in the MR2 I'm not finding a totally sweet spot. This would suggest that the bass reproduction has some horrible peaks and troughs in the frequency response. Frankly, given what I did, that's no surprise. I'm more astonished that it works as well as it seems to.
