I am currently searching for some replacement speakers but in the meantime, to improve the sound of my current speakers I am experimenting... They are Wharfedale floorstanders with 2 bass drivers, 1 mid and a treble. The nominal impedance is 6 ohms. Currently there is a little too much bass for my liking so I have disconnected one of the bass drivers - the one sited between the mid driver and the lower bass driver. The sound has improved no end due to the reduced amount of bass. I'm concerned however on the effect this will have on the impedance and therefore the load on my amp. I don't have an ohmeter to hand so could someone theorise the effect on the 6 ohm nominal impedance removing one of the bass drivers will have? If, as I presume, the driver is connected in parallel, the impedance should increase with one driver disconnected?
