TangBand 871S Impeadance Compensation

Tenson · 28th April 2006, 11:40 PM

Just a quick one, does anybody know the values I need to build an impedance compensation network for this driver? I want to use it as a tweeter and crossover to a bass driver 1st order at 700Hz-1KHz. So I want to kill the resonance peak around 110Hz right?

Another quick question about impedance compensation, having never done it before. If I stick my Seas CA18RNX in a 29liter ported enclosure, will its impedance response change? I don't have the bits to measure impedance response so I was hoping I could use the graphs supplied by the manufacture for both drivers.

Cheers,

Okay no worries about the network component values I managed to work them out.

However, I'm still interested to know if the impedance of the driver is going to be very different when I mount it in an enclosure? I would think the enclosure mainly effects the woofers impedance bump, but not so much the rise over higher frequencies and that the enclosure is tuned too low at 30Hz to effect the impedance bump of the TangBand 871S. Would this be right?

Anyone?

If you tune too low, the impedance would be close to the free air impedance, and you will not get the performance you might desire.
