Designed to integrate cleanly into home cinema and hi-fi systems, the three models in the range offer a choice of driver size and output to suit different room sizes and system requirements.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003eThe Flagship Model\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eThe Q SUB120 is the largest and most powerful model in the Q SUB range, built around a 12-inch driver in an infinite baffle enclosure with an effective volume of 44.1 litres.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eIt delivers a maximum SPL of 114dB at 1 metre and a frequency response extending down to 28Hz, reaching deep into sub-bass territory that smaller models cannot access. At 400 x 400 x 432mm and 22.5kg, it is built for larger rooms and systems where serious output and low-end extension are the priority.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003eDSP Room Integration\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eOnboard Digital Signal Processing handles the heavy lifting when it comes to system setup.
