My system works this way- the woofers in the Avantgarde Duo are two 10" dynamic drivers with horn loaded drivers for the mid and tweets. Those woofers don't go down very deep and I found it necessary to adjust them so they cohere with the mid-horn, making the bass reticent. I added large 15" subwoofers, fed from my line stage that I DSP'd and dialed in to they sound continuous with the main speakers. The subs roll off at 55hz on a steep slope 24db/octave. In that sense, I'm using multiple woofers that cover different ranges. I would not call the integrated Avantgarde woofers "subs" in the true sense.
Has anyone here set up a system with tiered subwoofers handling different bass spectrums?
Has anyone here set up a system with tiered subwoofers handling different bass spectrums? I currently have bookshelf speakers fully crossed over to a pair of smallish symmetrically placed, force-canceling stereo subwoofers at 160Hz, and I am thinking about adding a big, ported sub and fully crossing that over to the stereo ones at 60Hz. My setup will easily allow me to do it (I have a miniDSP Flex that is applying DIRAC Live room correction to my current 2.2 setup downstream and that preamp is handling the full bass management duties right now, so the miniDSP only sees a pure 2.0 system at the moment--I can just attach the new sub to the second pair of outputs and use the miniDSP to handle this level of the bass management). Am wondering if anyone else has tried this? I am looking to improve bottom end impact and extension with the big ported woofer (looking at SVS PC-2000 Pro) since the stereo ones are not currently reaching down as low as my previous sub (currently a pair of SVS 3000 Micros; before these, I had a single SVS SB-3000).
