Why do subs sound bloated or slow?


The use of subs in 2 channel audio is controversial around A’gon. Detractors argue that subs usually make a system sound bloated or slow.

IME, the two biggest challenges for integrating a sub into a 2 channel system are optimizing frequency response and optimizing transient response. When frequency response isn’t flat, the bass sounds bloated. When transient response isn’t time aligned, the bass sounds slow.

Here is my pet theory about why systems that use subs often sound bloated or slow: Under many circumstances, optimizing frequency response and optimizing transient response is a zero sum game. In other words, getting one right usually means you get the other wrong.

As said earlier the crossover point. The crossover point is the main and possibly the only reason for a sub to sound bloated. If your mains go down to 50 and your sub is crossed over at 80 with a very slow slope of 6db you could have a problem. Also having the sub too close to a corner can accentuate humps in the subs frequency response.
