I own both Hawks (living room) and Rainmakers (home theatre) and can say without a shadow of a doubt that they share much of the same characteristics: smooth, musical, transparent presentation that really makes you forget about all that hi-fi stats distraction and lets you enjoy what you're hearing.
Let's take a look at it from the hi-fi stats angle, though:
Hawk: 5.5" driver, 6 ohms, 86db sens
Forest: 6.5" driver, 8 ohms, 87db sens
Rainmaker: 5.5" driver, 4 ohms, 87.5db sens
Model One: 5.5" driver, 4 ohms, 87db sens
So, you can see that the Forest really doesn't have a bookshelf equivalent but the Hawk has two. The Rainmaker is quite a bargain, but of course the Model 1 sounds better if you can afford it.
The Mani-2 is a phenomenal speaker, but has considerable power amp requirements (both quantity and quality) due to its isobarik configuration - search google for more info. Be very certain you have enough power before going down that path, and if you're unsure then you almost certainly don't have enough :)
