Subwoofers are never used alone, as they are intended to augment the low-frequency range of loudspeakers that cover the higher frequency bands. The typical frequency range for a subwoofer is about 20–200 Hz for consumer products, below 100 Hz for professional live sound, and below 80 Hz in THX-certified systems. On the left, a version with transparent cabinet is shown where the large magnet (grayish colour) of the speaker driver can be seen in the middle, close to the brown damper.Ī subwoofer (or sub) is a loudspeaker designed to reproduce low-pitched audio frequencies known as bass and sub-bass, lower in frequency than those which can be (optimally) generated by a woofer. If I play at max spl in my garden, the sound level is so loud that you need to escape to the other side of the main building if you don't have hearing protection on.A typical Hi-Fi subwoofer (r.), with the subwoofer loudspeaker built into a cabinet. That's partly because I use an active filter to filter the lowest bass away from the monitors and partly because they have a bi amp + a protection circuit stopping you from burning the tweeter. I can play so loud that the tools from my garden shed start to drop from the walls - without risking to kill the monitors. I myself use a pair of Behringer 2030A speakers combined to a 2,5 kilowatt amp + horn loaded 18" compression woofer (cheap, I know - but it's only for random fun not pro stuff).
You can get models up to kilowatt range that will let you deaphen your whole family before the tweeter blows. You have only two options to fix your situation (and by this I mean to preent you from breaking yet another speaker set):Įither play at lower sound levels or buy a proper active speaker set.
When you try to play music louder than your amplifier is rated for, the sound starts to distort, compressing the output heavily and the end result is that the tweeter gets fed several watts of continuous audio power instead of the 1-2 watt peaks it's designed for. The tweeter blows when you expose the tweeter to a distorted sound.
