For controlled-directivity waveguide systems, here is an approach I came up with. A CD waveguide for 1kHz and up, a horizontal shaded array for 1kHz down to subwoofer crossover point. Maintains pretty good directivity pattern control, though appearance-wise it isn't the best sitting above an...

Heck, even with one person's hearing curves. Measure a speakers response at the listener with nothing around him, then put him in a high-backed chair or put someone next to him. +-2dB? Good luck with that.

One thing you'd get with an HTPC over one of the dedicated streamers is access to free Hulu and Spotify. The WDTV does the plus or premium version of these, but not the free ones you can get through a PC. So if you want them, prepare to pay more monthly or get an HTPC.

If you have a low-Q woofer and want to lower the resonance and raise the Q, just add some mass (weight) to the cone. Get a Woofer Tester and a glob of modeling clay and you can find the tradeoff experimentally, then when you find the right amount of mass, glue some wire (or leaded solder) to...

Second vote for the Panasonic Lumix models. You can get a large optical zoom and image stabilization for not really much money at all. We have two of them (previous years' models, 6x zoom, 5Mpixel, spent under $150 on each) and have not had a single problem, not even from the one that got water...

Why not let the listeners set the volume level for each themselves? That's what they do when they listen to compressed/uncompressed sound on their own, it would be a more fair test -- which do they like better when they can adjust either to any volume level they want?

I've got a pair of their Radia 520 and can vouch for them. These are 50 inch dipole ribbons, with cone woofers at the bottom for below 250Hz. They certainly do it for me, best things I've run. I equalize the high end above 6kHz (using a Berringer FBQ2496), since the long ribbons tend to roll...
