Dsc Pc5010 Master Code Reset. Fostex FE167E Fullrange Speaker Driver Note - this driver has been discontinued and is no longer being produced. The Fostex FE167E is a 165 mm (6.5') full-range loudspeaker driver. Like most Foxtex speakers, the driver is well built and provides good performance for the cost. There are several projects on the internet that have shown the Fostex FE167E driver using in a variety of enclosures that include sealed, bass reflex, Transmission Line and Quarter Wavelength enclosures. The FE167E is a magnetically shielded driver and constructed on a stamped frame. The paper cone and whizzer are constructed from banana plant fiber which is very light. The efficiency of the FE167E is relatively high (about 94 dB / 1W at 1m) and the frequency response is good through the midrange but a little rough on the top end.

This driver is best when listened to slightly off axis. The small excursion of 0.6 mm limits the maximum potential output. Photograph 1: Fostex FE167E Fullrange Speaker Driver There are a number of small modifications and tweaks that can be made to the speaker driver to improve performance. For examples, most of the the ideas shown in the page could be applied to the FE167E.

Is there any advantage using a single full range driver rather than a two way speaker box? I have a pair of Bose 201 Series IV and it looks like a Fostex FE166E Full.
