You mean an additional filtering circuit and not just the typical oversized value series inductor for the woofer?
BSC is built into most commercial loudspeakers. Rather, the exceptions in which it is not included. Then there are a bunch that have varying degrees of compensation built into them, so the story isn't simply black and white.
In most cases, a low-pass filter with an oversized value provides the compensation.

Sorry but I do not recall any Brand which was using a parallel RL filter in front of the whole speaker.
AllenB, could you with your skills explain how that work a little?
You don´t have to explain "in super technical" terms, more like you speak to a construction worker.

Obviously it's not common, but it's interesting. The inductor cuts everything moving up in frequency until it's impedance is near that of the resistor. Higher than that, the resistor sets the maximum impedance of that part of the crossover. The response kinks, but levels out again. The tweeter mostly just sees resistance.
In a real scenario you'd have varying driver impedances to deal with which could vary the outcome. Each case is different, but both sections being in parallel is going to offer some potential degree of impedance compensation.
