Bluetooth speakers. Why so good?

And agree that, to my ears, the system in the Coupe is dreadful. But the Tubi exhaust note more than compensates...

A car is never going to be a good environment but the B+W in the Jag XFs that I've had were really jolly good (for a car). The exhaust note sucked, though....

yeah...my CL500 and CL600 had the best sound of any car I've ever driven...inside.

I agree about transmission lines, by the way. For a good many years, I had a delightful pair of 10 foot transmission lines that could manage a 32foot organ note, so I came to appreciate the real life benefits of transmission line speakers, whose technical benefits had first attracted me. I came with them when Mrs Surrey married me and they survived many anniversaries, but I have to admit they were big, about the size of 4 drawer filing cabinets. The inevitable happened. "Could you not get something smaller?" and I arrived home one day with a nice compact pair of TDL floorstanders, about 1/3 the size, but still a good 4feet tall. In retrospect, I think Mrs Surrey may have had shoebox-size in mind.
The TDLs are flawed, but they never fail to put a smile on my face every time I fire them up. A lot like my Maserati really.

One of the things I wondered about the little bluetooth speakers with the built in amplifier, EQ and goodness knows what else, is whether the manufacturers include motional feedback, whereby the actual movement of the driver cone is monitored, compared with the input signal, and the output signal of the power amplifier is adjusted to suit, microsecond by microsecond, so that the resultant movement of the driver cone has more to do with the input signal and less to do with enclosure resonances than it otherwise might.

I remember the huge improvement in loudspeaker sound (particularly imaging) that accompanied the arrival of rare earth magnets and I am struggling to understand what technology change has resulted in tiny little speakers sounding so good (not as good as real ones, of course, but startlingly better than their size would have indicated.) Is it really just a general improvement in loudspeaker design? If so I need to listen to a whole range of modern (passive) bookshelf speakers. Perhaps Mrs Surrey might yet get her shoebox sized speakers.

Well you've called out one specific example in your question. But best not try to compare active BT speakers with passive designs. They are both 'good' but I really doubt that a passive speaker in a BT form factor will be that great.....

There have to have been some advances in technology, etc. such that these smaller packages deliver much better sound...but it's still clearly uneven. And I still have to believe things like cone size, distance between speakers, etc. have to be factors...

Yup. Have a pair of TDL studio 0.5s

Oh Eb. I didn't know.
Note to readers.....Mine are merely G30s, not the hi accuracy models Eb has. But, though flawed, they put a huge grin on my face every time. Yet more Maseratiness in sound systems.....

On the face of it, the transfer function of the G30s would be nonsence with the usual kind of approximations in RIAA equalisation stages. But in practice, with just a little bit of sound pressure to fill out the percieved spectrum, they are an absolute delight.
