    I have a B&C DE250 behind a STH100 and really like it.

    I have two of those 2.1 amps. I used one for many years in an 8" TangBand sub with various satellites as a PC 2.1 system. A few years ago I made a pair of speaker stands that put the satellites off the desk. Very glad I did that.

    My current PC 2.1 is a Dayton 8" sub kit using their 250 watt DSP plate amp and gobs of power for the satellites. That DSP amp is worth a look. You won't need much watts for your satellites.

    I like the way you are thinking. High efficiency paper cone = lower energy usage = cool! (no pun intended, ha ha).

    mini econowave-inspired desktop speakers

    I am fond of efficient speakers powered by low-wattage amplifiers. Any thoughts on an econowave-inspired desktop speaker for use with the PC? I am in love with the sound of the B&C DE250 horn driver and was thinking of matching it up with a B&C 6NDL38 6-1/2" woofer. It looks like it will do well in a smallish box of around .25 cu ft. I'd like to use a mini-dsp and actively crossover with 2 topping amps. The pair would only play down to 80Hz or so where I have a 10" Dayton sub under my desk for the lows. I am uncertain of the horn but was considering the Faital Tractrix as I want to keep the width under 8" to save deskspace.

    If anyone is interested, my current desktop speakers are very simple, a 5-1/2" silverflute with a peerless BC25SC06-04 tweeter and a 1st order crossover and the same 10" Dayton sub. Efficient, cheap, and sound very good. Currently, powered by a now-discontinued Dayton 2.1 plate amp.
