Default Efficient 4" 4ohm speaker

Anybody know of any 4" 4oHm speakers that are more efficient than this one?

SP-60/4 - Monacor HiFi bass-midrange speakers 60Wmax 4Ω - Europe Audio

Its to be used as a midrange in a portable device on a tiny amp, so im looking for the most efficiant I can find that will keep up with my tweeter.

Looks like the Fostex FE103EN is actually more effecient than that, even though the T/S effeciency is 1db down. Others with experience with this driver may be able to help you more.

90dB is going some for a 4" reasonably low Fs reasonable Q driver.

Bizzarely the 8 ohm version has identical specs, something is amiss.

On paper I don't think you will find anything better.

rgds, sreten.
