Midbass is that all-important frequency range between 200Hz and 500Hz and covers the most important instruments in our musical libraries: voice, cello, viola, brass, tympani, woodwinds, bass, guitar. Just about everything we treasure has some element of midbass. In fact, it is the foundation of almost all music.
Yet, despite its essential presence loudspeaker designers have traditionally treated it as just another frequency, counseling that for best performance we have only the position our left and right speaker cabinets to affect its correctness: closer together and midbass increases, farther apart it thins out.
Infinity founder Arnie Nudell was obsessed with midbass rightness. In his view, there was little else of greater importance. "Get the midbass right and everything else falls into place".
Infinity and Genesis loudspeakers of his design had no more chance to get the midbass correct than any other speaker for the first 50 years of his design prowess impact on our industry. And then, a flash of insight. Why not create a 4-way loudspeaker that offers users the ability to adjust the all-important midbass with the turn of a knob?
And thus, the adjustable midbass coupler was born, one of the quietest revolutions in audio's long history.
His invention covers the narrow range of 100Hz to 300Hz with a specially designed dynamic driver blessed with its own high wattage power amplifier and volume control. And, it works. This innovative approach to musical perfection permits the user an unheard of luxury: the ability to place the speaker pair where they image best, then tune the midbass to achieve sonic bliss.
This feature will, of course, be in our upcoming line of speakers to launch in late 2019. But, in the meantime, it's good to noodle on the benefits of midbass.
Music finds it critical.
