sounds goodThe two Diamonsd would sound phenomenal, yes.
Two Solo X's would be stupid for daily, yes.
Thadman has two TDX 10's fs, if you want to consider that route.
Incredible quality and good output. Work well.
Keep in mind that when yo ureach the 2000+marker you need to consider upgrading the electrical system
really wow, is that a 15" or 12"The Diamonds are SQL engineered drivers, meaning they are geared to create a harmony between sound quality and sound pressure levels. They are extremely loud drivers (have a very high power handling, not always equated to loudness but is related) and still manage to sound amazing.
1 D9 in its recommended enclosure with ~1000 watts on icixsound.com posted 142.6dB peaking @ ~54hz (140dB is a military jet takeoff). This is an extremely loud setup and would be uncomfortable to listen on a daily basis for many. I consider that SPL.
