As for wattage, the 25 watts/channel of my Dayens Ampino has been PLENTY for my 8 X 15 X 22 ft living room with significant sized opening to dining room.
I've spent a good amount of time this weekend working on subwoofer integration with the Lores. With the Hornshoppe speakers, the last couple octaves of bass are just completely missing. My subwoofer was pretty much on its own with anything under 100 hz or so. My microphone on pink noise measures the Lores performing down to 30 hz before really trailing off. I find the Lore bass to be there, but to be a bit light for my tastes and in my room. Subwoofer supplementation is definitely desirable for me. It's definitely much trickier to have to integrate a third bass driver into the room, though. The EQ curves I have to work up in my Behringer are more difficult, and then there's always a difference between the measurement and what my ears are telling me.
I find the bass quite tuneful and articulate with the Lores, but in my opinion they do need some support for weight in the bass arena and also deepest extension.
At this point, the Lores have about 25 hours of solid performance on them. I wouldn't say that they have opened up substantially more since about the first 10 hours, but I have been listening to them almost continuously, so I'm probably not noticing changes if they are happening gradually.
One concern that has arisen involves some of the mp3's I've played. Most of my collection is lossless ripped from my CD collection. However, I do have some mp3's downloaded from the internet, at various bitrates. I have found with a significant number of these mp3's that volume peaks create a "popping" or "ticking" sound in the tweeter. It's significant enough for most of those songs to make them unlistenable. It's not my amp clipping, as the popping happens no matter the volume of playback. It's the way the Lores are working with the signal itself. Not sure why Lores would be different, but the Hornshoppe speakers never did this on these same files, nor did Omega Compact Hemps or Tyler Acoustics Linbrook Monitors I've had. I hope this situation resolves itself with further burn-in.
