As long as you know their limits, no. Just be aware that they weren't designed for ear-splitting levels, but since you said you don't crank them loud you should be fine. Certainly much better than the speakers built into your TV (most speakers in modern TVs suck; by necessity, due to their thin cabinets, you're limited to drivers only an inch or two wide, with almost no cavity behind them). I wouldn't overly boost the bass control either. Every 3dB (a just noticeable) increase in sound level causes twice the amount of power to be sent to the woofers for those frequencies that are boosted. If you turned the bass knob all the way to the right (typically 10dB on most receivers) that's 10 times the amount of bass power.
