Posted October 6, 200519 yr I know they had some limited stuff in the past. Just wondering if there are plans to expand into this side of the industry.
October 24, 200519 yr It'd be interesting to see some filters with passband zeros. an example would be an "elliptic" filter. such filters have a very steep slope near the cutoff freqeuncy, but have a low slope beyond that.basically, past 1/3rd octave it might be -30dB or less, but the slope after this 1/3rd octave would be lower then normal.a limitation of any high slope filter is matching. in this case, things need to be matched moreso then a simple 24db/oct filter, and this may mean that potentiometers are out. either that or use DSP. the benefit of this filter to car audio may become pronounced when the tweeter is located in the dash area and the mid in the door.
