There are also two other versions without long wave but 2 SW: TPR-300AC for AC 120 V only, with car adapter to use the unit as a car radio. The model TPR-300AH is mentioned in the same documentation as for AC 110-120 / 220-240 V operation (switchable). There is one oval speaker 184x127 mm (woofer) and a 52 mm tweeter.
