Thanks for the quick response Chris, Adrian and Dr. House.
I think I now understand the +/-dB theory. Based on the above, can we say that since in room response is +3dB- 9dB as compared to +/-3dB in the anechoic chamber, the reduction in dB in the lower frequencies is due to the absorption by the furniture and room treatments?
On the ohm rating, I read somewhere on this forum, that even though the M80's are rated 4 ohms, they should still be run at 8 ohms on the receiver. Is that true? If not, do you think the Yamaha RX-A3000 (140w x 7) can run the M80's and V180 on 4 ohms?
In case of X-over, I read certain speakers claiming that they crossover at a lower frequency (2.2kHz or lower) to the tweeter, thus reducing the load on the midrange. How does that affect the sound?
Thanks
