Yes, but I'd go with the higher output and lower frequency extending Buttkickers. They do add considerable enjoyment even with good subwoofers in a system. The key is correct setup. They are to extend response to subsonic frequencies and reinforce the low frequency effect you hear. Don't turn them up too high or you'll ruin the effect and make them seem gimicky. They should add palpable thump and shudder when appropriate and be virtually non-existent otherwise. Once dialed in correctly they area definite plus. Turn them back off and you really miss them. If otherwise, you did something wrong with the setup.
