I read somewhere that there is a substantial difference between the original d&b amp presets and Lab Gruppen IDP amp presets for d&b Q series subs. I have heard both and noticed a lot more output on the Q subs on a Lab IDP than on a d&b D12 amp.
While making presets for my d&b speakers on a Powersoft amp I noticed this difference and wonder if boosting 4-5db in the 37Hz area, as they do in the Lab IPD preset -will be safe long term and what about SPL? The Q sub is tuned about 41-44 Hz if I recall correctly so boosting below that seems a little strange?
Below is a readout from the d&b and Lab amps. Guess which is the Lab :0)
Cheers, Andy
