    electronic crossover

    I passive biamp my monitor audio rx6 and it definately sounds better at high volume this way. Although the crossover split is different from a 2 way. One amp drives the upper bass driver and tweeter, and the other amp drives the lower bass driver only. Doing it this way makes the impedance...

    B&w 685s seem quiet when at full power

    There is nothing wrong with your phone, its just the output voltage is low. This is why you need to adjust your input trim to a higher level. On the A85 you can set each input at a different trim level to adjust the sensitivity so it matches the different output levels of other sources. eg...

    KEF LS50 disappointment :(

    Do you have the subwoofer positioned right in the corner of the room? This is usually the recomended place because it is where you get maximum room gain. If you have placed your kefs well away from corners and the back wall you will get minimal room gain (so not exciting those room modes as...

    KEF LS50 disappointment :(

    Again looking at the plot, I would be very pleased with the response you have obtained with the ls50 on their own. Although you could argue it is a few db too strong 60-150hz, it is very flat and even bar a slight rise at 65hz. Too most people a slight rise in output towards the bass end is...

    KEF LS50 disappointment :(

    Looking at your REW plots the kefs are doing well down to 50hz or so, so I think your point of crossover is way to high. Your sub is playing to much into the upper bass which is spoiling the the nice flat response of the kefs on ther own. I would set your crossover point around 40hz and...

    The benefits of using a Power Amp

    I would give the the bi-amp option a go with the rx6, The rx6 is wired a bit different from the norm. The upper terminals feed both the tweeter and the upper mid bass driver, while the lower terminal feeds the lower bass driver. When single amped the load seen by the amplifier is 4 ohms...
