I was wondering if a Dyn sub with the C1's would sound similar to the C4's as far as the bass is concerned? For me there is something special regarding the Dyn bass. I listen near field and as much as I love the C4's they are too large for my listening area. I've demoed the C2's in my home and they are the largest I can go but still there isn't quite enough bass. Currently I use a Rel B3 (I don't have a sub out) and although the bass is very good to me it sounds a little slow for the Dyn's.
I first placed the Sp101 platforms so that one leg fell with in the footprint of the stands that hold my mains. This way I could place each sub as close to its partner as possible. I then aligned the sub on its platform so its voice coil was as close as I could measure to that of the mains. I played a test tone that was about the same frequency as the crossover point. Having an RTA allowed me to measure the frequency response of the mains and the subs. Adjusting the phase control from zero to 180 degrees while viewing the RTA screen I found that the subs measured and also sounded best with a 70 degree phase angle. My mains have a first order crossover at 2400hz and are run full range. Tom Theaudiotweak (Threads | Answers | This Thread)
