In this way, the system extends the useful bass response without materially altering the established midrange balance and subjective character of the LS3\/5A.\u003c\/p\u003e\n\u003cp\u003eThe crossover is therefore best regarded as part of a complete electro-acoustic system rather than as an independent universal low-pass filter.
