Which do you prefer small speakers with a subwoofer or big speakers that do not need a subwoofer? I much prefer small speakers with a subwoofer. Peace and goodwill.
A small speaker and a sub does not really cut it, unless you play at low volume. The reason is that the bass octaves extend well above sub range. So, speakers do need a capable bass performance at power.
So a sub plus speakers with good spl. down to 40 to 50 Hz range or lower are required. Then it mates well with a sub.
A larger capable speaker with good bass extension at power is definitely preferable to a puny speaker and a sub.
