Achieving High Fidelity Sound

I'm not using crossovers Graham. I was just pondering that all loads can have inductance and capacitance. It seems that inductors have the same series/parallel formulae as impedance/resistance. Capacitor series/parallel formulae are the opposite. What I'm trying to say is one coil can electrically affect another, before even considering the mechanical interactions of the cones.

I like them because they are generally free or cheap. They are easy to cut and shape; just need scissors, penknife and postage tape. Low mass so don't store lots of acoustic energy so can rest them on a desk without any acoustic isolation underneath. I don't go for really large woofers as they are heavy, the moving mass is high and the profile is deep resulting in poor dispersion for non-bass frequencies. But I don't like really small drivers on their own either hence my suggestion of a speaker array with a mid-sized full-range driver; the moving mass per unit flux would be lower

I think I will see what DSP can do with a pair of CHR-120 wide-band full rangers, first of all. I really want to leave headphones behind as I like not having to wear anything on the head but MySphere 3.1 is the reference standard IMO. It is far above any headphone that isn't the K1000 and the out-of-the-box response of speaker drivers isn't remotely the same. Having MySphere as a listening reference is inescapable because just because I could set a speaker target curve flat and get it measuring flat, doesn't mean it will sound flat because ultimately the ears don't hear flat.

Not with conventional thinking and conventional speaker design, no. I actually don't want a headphone sound; I only want a flat frequency response with speaker imaging from drivers that are fast enough to keep up. But a lot of attention to detail and R+D is needed for that to happen.

It's akin to trying to produce a solution without fully understanding the problem beforehand.
