Dynaudio C1 Bass

The C1s should extend flat to about 40hz. Have you measured them?

They are a great sounding speaker, but by no means will they do the 20-40hz octave. Just not gonna happen with 1 7" mid/bass driver

Wilmak - yeah, if you are missing bass in the 60 - 80hz range, then it is a 95% chance you've got a room-induced bass suckout with your current position.

Spend some time moving the speakers all over the place and testing, and also moving yourself around to see where in the room the bass is heavier. Rooms can easily do +/- 15 DB in the bass based on acoustics.

Can you measure the frequency response? There is free software called "roomeqwizard" and I believe all you need is a radio shack spl meter that will work as a microphone with it do to a complete freq response chart. That would def. shed more light

"extensive run in period like 6-9 months with 8 hours playing time per day. Before that, you cannot have descent bass."

A blatant lie. Play them overnight for a couple days and you will have "decent bass" as you say.

You haven't really answered these questions...

1. Can you measure them? 1 measurement chart would tell the complete story instantly. Go buy a radio shack SPL meter for $20 or whatever

2. Have you experimented with placement?

Hi Wilmak - Detailed instructions for using RoomEQWizard and setting up the meter can be found here:

Radio shack should have whatever cables you need
