Speaker for 300b amp?

Earlier in 2025 I adopted a SE 300B Power Amp’ and Floor Standing Coaxial Driver Speakers, under the guise I was to create a experience within my own system that through a few different demo’s in 2024/2025 left me quite impressed.

The New Amp’ and Speakers are used in comparison to my main system and the result is I am won over.

This same experience led to thinking about changes that can be made within the main system and if all goes to plan these will be in place prior to 2026.

I strongly suggest looking at a modern driver design Coaxial Speaker with a Driver offering over 100dB for the upper frequency and close to 100dB for the lower frequencies.

 Note: When adopting High Efficiency Speakers, noise within a system will be very speedily discovered, resulting in additional work within the system. For myself, I can happily push volume above normal listening and experience a quiet background. It might be worth cranking up the volume to learn what is revealed as background noise in the owned system to see how HE Speakers will integrate initially.

Most of the speakers that I have used with 300B amps are not in production. If I were in the market I would take a hard look at these speakers:

I sense a nice combination of more modern sound with efficiency, meaning speed clarity plus the beautiful midrange possible with 300B. 

Resist the pressure to get more and more bass, go for more and more midrange and accessibility to the music..

Best of luck

The Shinjitsu look a lot like the JBL 4367. Since they mention use with low power amps, however, they must have a more benign impedance curve. Sensitivity given is close 96 vs 94 for the JBL

I have tried the JBL 4367 with low power, and it just doesn't cut it.

Pindac, what floor standing coaxial speakers are you talking about?

Antigrunge2, I'd like to be able to pressurize the open floor plan of the ground story of my house- stereoroom, dining room, and kitchen. Maybe 1400 square feet.

Thanks for all of the responses, they are helpful.
