The \u003cstrong\u003e1HDP-8\u003c\/strong\u003e is the entry point — 1\" phenolic diaphragm, neodymium motor, ABS horn, 108 dB, 120W RMS, and a 2 kHz HPF. The 2HDT-8 delivers 6 dB more output (perceived as ~4x louder), wider 57° coverage vs 35°, and a significantly lower crossover point.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Why is the sensitivity rated “with horn”?\u003c\/strong\u003e\u003cbr\u003eA: The \u003cstrong\u003e114 dB sensitivity\u003c\/strong\u003e is measured with the aluminum horn attached — the horn focuses and amplifies the driver’s output, significantly increasing sensitivity compared to the driver alone. This is standard practice for horn driver systems and reflects real-world installed performance.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Can the SQ-HDX-2HDT-8 replace a midrange driver?\u003c\/strong\u003e\u003cbr\u003eA: With a \u003cstrong\u003e900 Hz HPF\u003c\/strong\u003e and frequency response down to 630 Hz, the 2HDT-8 can cover upper midbass through extended treble in a 2-way active system — reducing the need for a dedicated midrange driver in some builds. Use a DSP to set the crossover point precisely and manage the significant level difference between the 114 dB horn driver and your woofer.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Is this sold as a pair or single?\u003c\/strong\u003e\u003cbr\u003eA: The SQ-HDX-2HDT-8 is sold as a \u003cstrong\u003esingle unit\u003c\/strong\u003e.
