Alphanso PA520 is a standard PA speaker pair suitable for home environments. Recommended room size 2200sqf. This stereo pair is incredible for home practice, watch films or listening to music. The passive crossover is well-tuned at 2.3 kHz and can save the internal speaker from astonishing frequencies. These are lightweight series and capable of handling sufficient power respect to their sizes. PA520 has two 12-inch speakers in both cabinets and a 3-inch piezo tweeter. 1.5 inch voice coil inside woofer with a 5-inch magnet is good enough to shake the 12-inch woofer. Crossover frequency can be tweaked a bit by changing the capacitor inside, but not recommended for non-professional.
