My Snappers sounded very ballsy on the low stuff. They roll great iron, makes low output impedance, typically <2ohms actual Z, which is lower than most of the big names. Yet the transformers are still small. I don't know how they do it, but they claim to work really hard on the transformer designs, all wound in-house. Even my 300Bs have 1.8 ohm actual outputZ, makes nice bass.
