New Product Tab

The R400b’s reinforced and solidly braced cabinet houses twin 9in. LF drivers powered by twin 250W Class-D amplifiers. The drivers are mounted back-to-back: This ‘force cancelling’ arrangement nullifies opposing reactive forces. The result is virtually no cabinet agitation and therefore a clean, fast, powerful bass performance.
