But is the resonance the result of the mid-woofer reproducing sound between 800Hz and 1.2kHz or a by-product of port activity at the tuning frequency (centered around 66Hz)?
In other words, if we low-pass the speaker at say 500Hz will the resonance disappear?
I mean, who knows. there seems to be sealing issues and other sources of resonance.
I know Kanto isn't Genelec and only Kanto can say if they took structure born vibration of drivers and enclosure into account. If they did and if they tested for it then they could say so.
Acoustic sound coming out, mechanical vibrations, etc.
One would have to dampen and seal things then remeasure to see what the issue is.
Would more acoustic stuffing against the tweeter area stop some of the resonance? maybe, but it's not really worth my time to figure out.
These speakers are going in the garage where they will be great with the Bluetooth and power they have.
ON a side note Adam audio monitors have MUCH worse resonance I believe and they are sill used and loved.
This is a review and detailed measurements of the Adam A5X powered speaker. It was kindly sent to me by a member for review and costs US $499 each. Despite its small size, the A5X is quite heavy: The back of it got warm so I am assuming it uses class AB amplification or at least a linear...
