Dynaudio sub with C1's

Hi,

The Dyn C1s are great speakers, but even with a sub, they won't sound like C4s.

Adding a sub to the C1 will give you more extension, but the differences between the C1 and the C4 are far greater than extension alone.

As good as the C1s are, and they are some of the better monitors out there, they will never match the C4 in terms of sheer dynamic impact, staging size, bass articulation, etc. The C4's have much, much more cabinet volume, and more drivers dedicated to the mids / highs that the C1s can't match.

George,

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

Goatwuss is dead-on. The C1's with a Sub500 will not better the C4's overall for all the reasons stated.

However, I've owned the C1's with dual Sub500's and I loved the combination together. The Dynaudio subs don't get the praise that they deserve, they are wonderful and mate extremely well with the C1's.
