Sir Nelson, how about for 2 channel Music application. BS with Sub vs FS? Let's say same brand of speakers except sub and same brand of Amp..
Given only the two choices, i would prefer BS with sub. Pero excluding high end speakers like mga Focal EM series nila. They can go low and smooth up to 25 hz ata.
The reason why i'm an advocate of sub for stereo listening is because there are some tracks that contain low freqs, which, some speakers, be it FS or BS, can hardly reproduce. Minsan yun extension ng lows sa FS nawawala. Pero of course kailangan din ng smooth and proper integration. Most often, yun sub positioning and peaks ng room ang kalaban sa proper integration.
