Thank you very much for your information.
In mh-audio.nl calculation, what is the amount of attenuation required?
Is it necessary to add Zobel Resistor and capacitor in the circuit?

Generally start with modest attenuation, maybe 4dB. You can try first without the zobel parts.

OK and thanks.
How about the power(W) for Rbsc resistor I should select after calculation?

10 watts should be OK with this speaker.

How about 15W resistors?

Is this kind of air core inductor good for full range drivers?

Thanks.

Anthing 10W and up is fine, so 15W is good. I'd choose inductors with no more than 0.2 Ohm DC resistance.

Tony, for the Baffle Step Correction, you can actually make different versions. For Desktop/Near Field/Close to wall placement, 3dB is usually adequate, but for free standing, say 1m from the rear wall, 6dB would be better.

BTW, where can I buy your speakers in Hong Kong? Are there any retailers? They look pretty awesome! How much's for a pair of CHR70 with piano black cabinet?

Hi Boris,

Thanks for your advice. I will try it out later.

You can buy the speakers at Rm. E, Flat C3, 7/F., Block C, Tuen Mun Industrial Centre, 2 San Ping Circuit, Tuen Mun, H.K.
The price of Till70 cabinets in piano black for CHR-70 is USD120/pair.

Thanks,
Tony.
