DBR12s are my first powered speakers (I've used passive speakers until now) and I have to say I love them. Clarity of the sound is fantastic and I noticed the speakers perform the best up to 3db volume setting (perhaps with the sub I could go little higher). Speaking of subs, I was deciding..a looong time... whether to go for 12 or 15 inch version. Since I intend to use them with sub I went for 12. They are not too basy but still impressive for 12inch especially when the D countour is used. So if you're looking for that extra bass without sub I can only imagine the15s would be better in this respect. In my case I saved a little money on each that I will invest in decent sub. Last but not least I had heavy 28kg speakers before and DBR12s are just below 16kg each, so lifting them on the pole is easy. Connections - more than I will need or use so happy there. Seems solid build quality and I wasn't sure about the design but they do look great. The Yamaha warranty for DBR series is 2+2 so not 7years, but I'm happy with that too. The speakers are to be tested on the road but for now I'm happy.
