SB Audience ROSSO-65CDN-T + ES-600 Biradial Wood Horn

[@maz4bz592]

Brilliant, thank you! Only comment is the audio level is quite low and I had to max out my volume to follow your voice.

[@basberger5921]

Very informative as usual with clear explanation. Always a pleasure to watch your videos.

[@JosephCrowesDIYSpeakerBuilding]

Thank you!

[@Clobercow1]

Easily on my shortlist! Nice review!

[@RomanTecDev]

Proper approach as always! Folk who design speakers highly approve!)

Great review! I just picked up a few to test. The 44cdn-pk and 44cd-pk. I was also impressed with the distortion compared to SPL. Such great performer. I was really excited to see that you got similar results with the larger diaphragm.

[@JosephCrowesDIYSpeakerBuilding]

Thank you! I chose the 65CND-T since it has copper shorting rings in the motor structure to lower distortion. SB Audience currently does not offer this feature on their small format drivers, so you may not get similarly low distortion figures as the 65CDN-T.

[@zillar5]

@@JosephCrowesDIYSpeakerBuilding in your opinion, do you think the non neo version will perform similarly?

[@NiToNi2002]

Thanks for a great review, Joseph. How does it compare to the DCX464, 4594Nd and 745/951Pb?

[@weareallbeingwatched4602]

Absolutely this displays what I have always known about compression drivers - they *ring* at high frequencies. I would even suggest that the inaudible ultrasonic distortion likely constitutes a health hazard in some cases, and that "fatiguing" metal dome tweeters deafen the listener with ultrasonic distortion.

[@rhalfik]

And how exactly your ears would pick up these frequencies? :) Does human eardrum move to ultrasonic frequencies?

[@JosephCrowesDIYSpeakerBuilding]

I’ve suspected the same. Even 60Hz flickering LED lights I believe affects mood.

[@FoxGhost7]

@@JosephCrowesDIYSpeakerBuilding If your LED would flicker at 60Hz you'd get a headache pretty soon. Don't buy cheap stuff. But that's not how modern LED lights work and the good ones go above 500Hz. Which is absolutely fine.

Very nice test, Joseph. Interesting that your measurement shows pretty flat response until 10kHz and only drop 2-3dB until 15kHz. That's in contrast to the official FR which shows a gradual drop of 8-10dB from 2kHz to 10kHz. What do you think contribute to the difference? Something with the horn loading?

[@EngineeringEssentials]

Great review, I have a question for you. Why this driver playing up to 17kHz is okay? Ideally, it should be 20kHz right? Please correct me if I am wrong, Thank you!

[@JosephCrowesDIYSpeakerBuilding]

With this size category of compression driver it is always a balance of various parameters that must be considered. The driver is able to play effectively down to 500Hz and so naturally it will require very careful engineering to achieve good performance in the upper treble. The diaphragm is 65mm in diameter which contrasts to dome tweeters which are usually 19mm to 29mm...a big difference.

[@TDA-AUDIO]

Joseph good test. Vs de620?, vc Yamaha? (you old test)

[@JosephCrowesDIYSpeakerBuilding]

The ROSSO is the better of the bunch. Truly a a great driver. Pair it with a good horn though.
