Is the 272 watts of the PE amp enough to get the tempest going. I want a low Q sealed design for music, and i want to know what kind of box i should build(from your suggestions), and if i will need more amplifier power. My speakers are down -2db @ 30hz, so i want that really low, hence wanting a low Q, Is it possible to make the low Q design of the tempest taller and thinner? Thanks. Would switching to a rythmic 350 watt be better? i just don't want to rob myself of the performance its capable of. Thanks.
