Everybody has their audio thing. Paul’s is mid bass and his thoughts are not unreasonable. Except, if too much mid bass, something else suffers. Pick your audio poison.

The mid bass dilemma

Mid bass 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 mid bass. 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 mid bass increases, farther apart it thins out.

Infinity founder Arnie Nudell was obsessed with mid bass rightness. In his view, there was little else of greater importance. “Get the mid bass right and everything else falls into place”.

Infinity and Genesis loudspeakers of his design had no more chance to get the mid bass 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 mid bass with the turn of a knob?

And thus, the adjustable mid bass 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 mid  bass 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 mid bass.

Music finds it critical.

Higher and higher

As the frequency goes up, so too goes the price tag for amplification. Folks aren’t as concerned with the quality of bass amplification as they are with the mid-range region but both pale in importance to the attention and money paid to get the tweeter’s range perfect.

Think of all the ways we’ve worked on to sweeten the top end: tubes, low feedback, single-ended outputs, high class A bias.

When it comes to bass, we just want it to go deep and powerful.

Fact is, the higher the audio frequency the greater the engineer’s challenge to maintain purity, phase accuracy, and transient speed. Harder still is designing an amplifier good enough to handle both the power and depth of low frequencies with the delicacy and transient speed of the upper notes of music.

It is the rare piece of audio amplification equipment that gets high marks for all frequencies, but it is the upper ranges that we fight hardest for.

We can forgive “ok” bass but screechy highs are unforgivable.
