How's this for speaker break in?

I bought a pair of Soliloquy Sat-5 speakers from a local ebay seller a few weeks ago and put them in the closet. I had time so I hooked them up tonight. I put on a cd I hadn't listened to in a while (Kate Bush - Hounds of Love) and thought, "these things sound terrible." So I popped in Jane Siberry -- When I Was a Boy, a disc I listen to frequently. Same result, terrible. Speakers were lifeless, no dynamics at all. At one point I had to get up and put my ear to the speakers to ensure all drivers were working.
Well about an hour later they suddenly came to life they sound more like what I expected. Now it makes me wonder, did the Soliloquys need a few minutes to loosen up or have my ears adjusted to them? I nearly got up and unhooked them after three or four songs. Glad that didn't happen as they are sounding better even as this is typed.
