Hi everyone,
I have recently purchased a pair of KEF C80 in great shape.
They sound very nice and open but lack in the Bass section.
I am using a Sony CD player and Technics SL-MA1 turntable with Shure M105E cart, Yamaha C-4 Pre Amp, 2 X bridged mono Rotel RB-870BX Power amps (300w each at 8ohm) and good cables between the components and the speakers.
I tried many combinations with wiring (A & B on the speaker back) various distance from the wall, AMPs bridged and non bridged, different Pre Amp (Rotel RC-850) even an ADC sound shaper III...still very dry almost non existing Bass.
Room size is 11.5x15f and height is 7.2f
I checked the B139 drivers and they work fine, also showing the correct ohm on the tester. I looked at the huge crossover. Caps look in great shape.
I thought it was my room but I also have pair of KEF 104ab which I am using in the same room with excellent Bass....and the 104ab is only a two way speaker with a passive BD139 unit.
Any idea where I should look next to try and solve this mystery?
Thank you,
