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.

Thoughts?

The answer is simple. Its because people stick there ultra powerful subs in a corner, which throws massive boom, and is often far away from the mains as well. I have been saying the same thing here, and nobody seams to get it. Put the sub under the center channel, between the mains.....put your electronics in the corner! If you do this all the problems are gone. In the older days subs stunk IMO, even the good ones cant compare to subs now. Back then corner placement was about added db gain(they still never blended right then either). These days, putting these huge, powerful subs in the corner is rediculous. The ONLY way I would try a corner placement is if you were running the sub under 40HZ. Otherwise it never sounds right to me.

Why dont you put your main speakers against a wall, or corner? -Bloated, muddy, heavy bass, right? So why do it to your sub? I ran my sub at 100HZ with my Magnepan 1.6's and in the center position you would NEVER have known it was coming from the mains. Phase/distance issues are GONE!

I dont like any subs sound placed out of center.
