TBI MAGELLAN VI su Bass Extension Speaker

The MAGELLAN VI su driver uses an extremely stiff low mass single piece convex aluminum cone. The tuning for this model results in unprecedented performance with speed and warmth. The Magellan VI su will integrate well at crossover points as high as 200Hz with no signature. Low vibration is inherent to the design and allows flexible placement even amongst your existing components in the rack. You can use the MAGELLAN VI su singly or in pairs powered by our TBI 200 su or you can use your favorite high quality subwoofer amplifier or amplifier/crossover combination to customize your application.

TBI MAGELLAN VIII su Bass Extension Speaker

The MAGELLAN VIII su is truly a work horse in deep bass performance. When the need is to extend the bass of a speaker system that has good low bass it will be easier to blend with this model. The truly remarkable property of ETL™ designs is the absolutely constant loading of the driver cone at all frequencies to allow our MAGELLAN VIII su to perform to 10Hz at full power input. Performance into the infrasonic range is exemplary when you consider that it is realized with a low mass driver capable of disappearing in an audiophile system. We recommend this unit for extending the bass of mains that are going to at least 100 Hz for bottom two octaves and infrasonic extension.

TBI MAGELLAN VIII xu Bass Extension Speaker

​The MAGELLAN VIII xu is a new member of the TBI family and represents the best extension both high and low for our subs. Although it retains the same skin and basic design of the Magellan VIII su it has an enhanced upper bass output to deliver accurate reach to mains that may only reach down to 200Hz. In reality this is the most difficult challenge to accomplish and is one reason that all audiophiles cross the subwoofer over at the lowest possible frequency.

This unit also features a high pass crossover when you use the speaker level to input the signal to the amplifier.
