![]() ![]() Note that the delay is only used to obtain a better integration around the crossover frequency. I expect a system delay of about 2 ms, so you can set Delay to 4 ms (4 + 2 = 6, which corresponds to about 2 meters of runway difference to the speakers), you can enter which values you want even if the steps are rough. Measurement up to 1 kHz is sufficient and will be over.Īs for the software control, you only need to change Gain, Out1 and Delay. ![]() Translates this (which fits with the speaker subwoofer in that listening room / living room): See pages 25-26 (many pictures so you do not need to know Swedish to understand how it works). However, I have a good feeling about the analog active filter LD X-223 which has a sensible spec and which has good conditions not to interfere with the signal audible for the high-pass part.Ĭlick to expand.From the link I referred to in my previous post in this thread. Equalizer: the t.racks DSP 4x4 Mini (slightly higher performance than MiniDSP 2x4 and lower price as well, though a bit uglier interface in the software). However, I found an alternative in the t.racks DSP 4x4 Mini which seems to have slightly better performance and which is slightly cheaper as well, but this is not recommended for the high-pass part either. In addition, the linearity for both ADC and DAC is not the best (which does not matter in bass area, where the hearing threshold is significantly higher). MiniDSP 2x4 should probably only be used as an equalizer for bass because it tends to make a little too much noise for use in the high-pass part. Where a subwoofer would be integrated with speakers (LP -HP filter sub-speakers plus EQ), where it is said: ![]()
