Some people say Duntech speakers don produce enough bass, why is that?
If there is no bass in a recording then there should be no bass in the playback. Some speakers seem to produce some bass out of thin air, even while playing a soprano singer. This is because stray bass sounds in the recording are being blown up by the boosted bass. The other problem is that many speakers rely on a pure ported output. The correct way to do it, is to use a combination of ported and sealed output, which Duntech have found is the only way to create satisfying and accurate bass (which is why the entire Gemstone range and the Prince use this operating principle!) What happens in a pure ported enclosure, is that the sound is produced by both the bass driver and the port. The sound from the port is delayed in time because the sound is actually the result of a plug of air in the port “bouncing” on the air in the enclosure. This takes some time to happen and the lower the frequency the greater the delay (in technical terms it is called “group delay”). This delay produces a muddy
