Related to the issue above, large excursion woofers often have poor bass extension and require active EQ to get a reasonable bass response.

巨大冲程的低音喇叭通常有很差的低频延伸，需要有源EQ均衡电路来获得合理的低频响应。

Finally, the effects of the parameters on the response and first excursion probability of a SDOF linear system are discussed.

分析了这些参数对线性单自由度体系的均方响应及首超概率的影响。
