Midrange frequency is between 250Hz to 6000Hz. Few examples are human voices and most intrument's sound.

any nice usb speakers for laptop? i used logitech s100 before and the sound aren't that nice. Is the edifier MP210 really nice? Although kinda pricey.

Haha yeah, the purpose of a subwoofer is just to produce bass and low midrange sound, not to shake the house heh. Not sure how you're able to shake the roof, because I weren't able to shake my kampung house with floorstanding loudspeaker (have few from 10-12" woofers) when I was ah beng days last time.

Now I no more love for seismic sounds lor, going to flat response sounds now. I prefer the edifier MP221 over my 10 year old 2.1 because the 2.1 sound is just horrible now, very boomy but bass notes are just indiscernible. I still had another 5.1 though heh (bass knob only turned a little).
