Linn Majik 109s:

As per the Stereophile review:
"The impetus for this design came from Linn Japan, which was pressing for a bookshelf model diminutive enough to easily fit into a small Tokyo apartment. As a result, Linn chose a front-firing port to enable the speakers to function properly when placed flush against a wall."
