Is this how a Subwoofer Crossover is supposed to work?
It may help you to think of crossovers if your realize that the are not independent of the sub's own natural rolling off of higher frequencies. The low pass filter in the sub ADDs to the natural low pass filter. To figure out what you are starting with, set the HP filter as high as you can and measure there. |
Not an
expert, just my 2 cents. I thought the frequency the levels would start to roll off would change, i.e. flat to 50 hz then a sharp drop, flat to 90 hz then a sharp drop, etc. etc..Yes, but depend on the crossover, usually subwoofer low pass filter slope is 12 dB/octave instead of a sharp drop. But Starke says this is how a subwoofer crossover is supposed to work.I think this is how a Starke subwoofer crossover supposed to work. Is it possible to buy an inexpensive active crossover that I could use in place of what is built into these subs?Look like you can't bypass the built-in crossover! Any chance to return it? |
erik_squires I can remeasure with one sub and set the crossover to its 200 Hz high point but I'm not sure the results will show much difference but you can never tell. I am using a Willsenton R8 tube amp to drive Moabs. If I want to add subs to level out the room nodes they either have to be connected at the DAC which is why the SW12's looked ideal because they have a balanced input so I use the balanced outs from the DAC to the Sub and the RCA out to the R8. From their web page I can't figure out how the MiniDSP would fit into that setup. |
imhififan1 Shipping costs returning the subs would be a significant portion of the purchase price. I would rather figure out a way to make them work for me if possible. |
