Extended LF Ferrite Transducer - Altoparlante in ferrite
L’Eighteen Sound 18LW2400 è un altoparlante per basse frequenze con diametro nominale di 18 pollici (450 mm). Il suo progetto nasce per l’uso in applicazioni dove sia richiesto un alto SPL.
Infatti, il 18LW2400 nasce per l’impiego in subwoofer configurati bass-reflex, passabanda o caricati a tromba.
Rispetto allo standard industriale 18LW1400, il 18LW2400 offre un SPL massimo più elevato, una maggiore gestione della potenza ed una minore Power Compression.
