With the capacity to embrace a range of nine octaves in a system, the E100HD MKII offers among the widest bandwidth of any single drive unit on the market. This not only provides a seemless, crossover free sound, but allows for a wide range of applications and simplifies high quality designs as well. 

In a well designed cabinet these driver are capable of going down to 30Hz.

The E100HD MKII can be successfully used with all types of enclosures including closed or vented boxes, transmission lines and horn loaded designs. It is very suitable for high quality, home cinema, hifi and custom installations.

The rise above 4KHz can advantageously be compensated by using a toe in and off axis listening (see illustration above, axis crossing in front of listener), which widens the horizontal soundstage as well.

As a full range unit, the E100HD MK II is also very suitable for 2 or 3 way systems, e.g. crossing over to a ribbon unit, where the wide band performance simplifies a 1st order cross over and the aluminium cone blends in seamlessly with the ribbon unit. The main difference between the E100 and E100HD MKII is the Cu capped pole piece, carefully selected to meet our specifications.

This extends and improves the high frequency response to 25KHz, reduces high frequency impedance, Eddy currents as well as distortion. Just like the bigger bass units, the E100HD does well in both closed and vented designs. With a properly tuned cabinet, the E100HD MKII delivers a firm and impressive bass. All EAD units do exceptionally well with live acoustic music, like Jazz or blues and voices are very clear and present in the listening room.

These full range speaker are designed by EAD in Sweden and benefit from being manufactured by ScanSpeak who are renowned for consistant and high quality loudspeakers
