FWIW... I find this speaker excellent for use with my Ten-Tec transceivers:

They are available either in Active or Passive models, but the Passive model has excellent efficiency. Avantone specs recommend an audio input power level at 10 to 200W, but I find it easily driven to shack-filling volume levels even with a LM380 output stage. Not inexpensive, but cheaper than most IKYT "aesthetically-matching" speakers.

Bullsh&t. What is needed for good speech quality is nothing more or less than a loudspeaker with flat response AND uniform coverage in the speech range. And, because many (most?) ham rigs don't have high power audio output stages, it needs to be fairly efficient. "Tailored to speech?" Horseh*t. Nothing more or less than a decent small, accurate loudspeaker that sounds the same over a fairly wide angle.

Now, it so happens that Optimus is the "house brand" that Rat Shack used in the 70s and 80s. They didn't make anything themselves, but some of the small speakers they sold under the Optimus name were pretty decent, and we used them a bit for making noise in rooms to do acoustic testing. But "optimized for speech?" Zebrash&t.

The reason that loudspeaker he likes sounds good on speech is that it's a decent "flat" (natural) loudspeaker. .
