I am building a small 4th order bandpass box for (2) IDQ12 D2 V.2. I found the box demensions and the predicted in car response curves on the ID tech webpage.
Image Dynamics IDQ12 D2 V.2 tech page When I model the same set up with WinISD I get a totally different plot. Before I start building can someone verify that this will work (and sound good - high output, low transient responce)?
