The Chapman fronthorns measures 33 inches in diameter and are spray-painted using pearl auto-colour from Dupont. The fronthorn has a Tractrix expansion flare and produces frequencies down to 140Hz. The stock Lowther PM4A is mounted with brass diffuser and the "crown" attachment to optimize the dispersion and prevent standing waves near the throat. These front horns are individually mounted on custom designed & built stand which isolates they from the basshorns. |
