Hello koestner! DBX makes a 2 way stereo/3 way mono electronic crossover (DBX223, be sure get the model with the kind of connectors/in & out plugs you prefer) and is transparent and reasonably priced. I use then in two of my 5 systems. They are a tweaker's delight, 24 db/octave and let you fiddle to your heart's delight. I agree that keeping the very low bass out of your main speakers is a good idea. I'm using Magnepan LRS and LRS+ in the systems with the DBX Xovers. My other systems use miniDSP electronic crossovers. Give each driver it's own amp. These days, good amps are not expensive. Happy listening.
Do No Harm ... well the least harm anyway
I want to insert a high pass filter between my preamp and amp (both Benchmark) so I can limit the frequencies going to my full range speakers (Ref 3A Nefes II) to over 100Hz with a 24 db/oct. slope. The 3 possible ways are passive, active, or digitally (A to D then D to A where this is done through software). I am seeking opinions on which method would be the least intrusive to the original signal (ie. best sounding). Thanks for any replies.
