Paradigm X-300 900 Watt High-Power Subwoofer Amplifier

Technology, by definition is the practical application of knowledge. When it comes to speakers, no one knows more than Paradigm. When it comes to the practical application of that knowledge, we’re committed to doing it better! Better measurements, better materials and better components always result in better sound … and better speakers.

While many speaker companies do not have the resources to design and manufacture their own drive units, Paradigm purpose-designs robust drivers for specific speakers. To ensure superb consistency our crossovers boast hand-selected precision parts.
Our high-power, high-current amplifiers with oversized power supplies and massive heatsinks deliver tremendous (and instantaneous) power output at all times.

Use your knuckles! Rap on our enclosures! As one reviewer asserted, they’re as dead as we claim in our literature! Acoustically inert high-density hardboard reinforced by strategically located radial braces limit unwanted resonances and increase enclosure stiffness.

Precision! Accuracy! Consistency! Long-term reliability! These are inherent characteristics of even the smallest Paradigm component part. Better technology … you hear it in every speaker we produce!
