KEF B139

SP1044 from a Kef Brochure

The KEF B139 was used in many commercial speakers and in many kits. Some of these include:

Both Bailey's original TL and his later triangulated line,
IMF TLS80 & Reference Monitor, Atkinson's State-of-the-Art TL, the Chris Rogers Pro9TL, the Webb TL, the Linn Isobaric, the Coffin, and in a number of Kef's speakers ... Many of these also used the Kef B110 midbass.
