First it was Sena who increased their 50 series speaker diameter to 40mm to enhance bass response and now Cardo have introduced the Packtalk Black with 45mm speakers.
Packtalk Black is, of course, black, but all other features remain the same. They also offer 45mm JBL speaker replacements for existing Cardo units for use with the app. Note they are not compatible with any other intercoms.
It’s all about the bass
Like Meghan Trainor sang, “It’s all about the bass”, although she refers to body size, not music quality.
Bass doesn’t really matter for intercom or phone conversations, but a lack of bottom end severely impacts sound quality for music, especially modern music that features a lot more bass.
Lower frequencies are wiped out by the abundance of mid to high frequencies caused by wind noise when riding.
Anything above about 50km/h can substantially reduce bass response. It is almost non-existent at highway speeds.
That leaves riders listening to shrill and distorted music which can be a dangerous annoyance.
To compensate, many riders now wear special filtered earplugs that reduce wind noise.
However, some of these can also decrease bass response.
