SoundTube C1.8 Series Three-Way Center Channel Speaker
The C1.8 series offers exceptional center-channel performance with a 3-way design that ensures smooth off-axis dispersion and high power handling. Available in standard, in-wall, and on-wall configurations, all models share a ported enclosure and professional-grade drivers for detailed midrange and extended bass response.
Each variation features a cloth snap-fit grille, gold-plated binding-post inputs, and 4 Ω nominal impedance. Crossover networks at 500 Hz and 3.7 kHz seamlessly blend the 1.125″ soft-dome tweeter, 3″ soft-dome midrange, and dual 8″ Kevlar woofers. Sold individually, these speakers integrate into any custom home or commercial theater setting.
