For even more control over the sound, a Custom EQ can be set up within the Alto App and saved directly to the TS4 speaker. Ready for anything - compact, versatile design Each speaker features a lightweight, sleek, black box design that can be used as the application demands - freestanding, as a wedge monitor, pole-mounted, or suspended via the integrated suspension points.

Review: Ottime casse con rapporto qualità prezzo pazzesco - Prese 2 TS412 per sostituire 2 Mackie da 15” che erano molto più ingombranti ed avevano meno potenza. Ottime casse, suono pulito e le usiamo per i nostri piccoli concerti. In abbinata con 2 Subwoofer Alto TS12S copriamo tranquillamente spazi per 300-400 persone senza ammazzarci la schiena. Abbiamo anche 5 Alto TX310 e TX410 che usiamo come monitor/spie ed hanno potenza più che sufficiente per fare il loro lavoro. Consigliatissime sotto tutti i punti di vista +++
Review: Parfait - Le baffle est vraiment parfait, sauf que le Bluetooth ne fonctionne pas avec .
