HF resistor change a revelation on 12" Tannoy HPD's

In the last few days, I reverted back to the original value resistor in the HF (from 27ohms to 47ohms). I had gone to the lesser value a few years ago, due to a perceived harshness in the HF's. Whatever caused that perception is now gone, the 47ohm Dueland carbon resistor has made a spectacular change for the better. $50 sure can make a difference.

Happy Fourth,

Room acoustics matter a great deal, including between and behind the speakers.

I'd be interested to know exactly what this particular resistor was doing. Doubling or cutting that in half seems like a big deal, but it's also a rather large value, was it in an impedance compensation network?

Hey Elizabeth,
It depends on where the resistor is.


Any time you want to go through a speaker crossover simulation with me I'll be happy to show you why this can be true. 

Best,
E
