Installation and cabinet guidance

Allow for a 45 mm opening and the 50 mm basket, with about 17 mm behind the panel for the magnet and solder lugs. Seal the rim to the panel so the front-side protection is effective; bonding and a front cover or grille may be needed.

Solder to the lugs and observe polarity. Match the 50 Ω impedance to the output stage and keep the drive within the 2 W rating.
