Bass Horns

The Bastanis line of passive powered speakers uses backloaded floor- firing bass-horn cabinets. This sounds complicated but there is an easy explanation which shows the big advantages of backloaded bass-horns for passive powered speakers.

• The horn transforms the air- movement from the drivers cones to a much bigger surface at the horn-mouth. This increases the possible max. dynamics enormously because for the same spl as without the horn there is a small percentage of cone- movement only.
• This also means that the amount of physical damping of the drivers resonance by the load of air is much bigger and so the required electrical damping is extremely low which is very good for the soundquality of tubed amps.
• The increased physical resistance of the basses coming from bass-horn cabinets is the only way to give high efficient passive powered speakers strong bass- response with the same efficiency as the midrange, any conventional sealed or bass-reflex cabinets could offer the basses with much lower efficiency only.
• The floor firing bass-horns are a big step up from the usual giant bass-horns because they work as well offering efficient, fundamental and dynamic basses from cabinets with common dimensions.
• The floor firing bass-horns react self- adjusting to the room and the placement, big rooms mean big floor- space, big virtual opening of the horn-mouth and so maximum contribution of the basses. Smaller room- spaces and close to wall- placement means smaller floor- space, smaller virtual horn-mouth and less contribution of the basses, so the bass- response stays strong and clean.

The Bastanis floor- firing bass-horn speakers are the most excellent way to get the unlimited basses you always were looking for combined with high efficiency, compact sized cabinets and self- adjusting characteristics.
