edsmiata, that's all well and good, but output is not the issue for me. The point is having the sound be good enough. Not my-neighbors-know-I'm-on-my-way-home-when-I-turn-the-corner-a-mile-up-the-road. I'm sure I could find a happy medium with a sub. But I will do so only if after testing the audio without it, I decide that I need it to clean up the sound. I could care less what other people, like you, think of my install. I am not attempting to create a high end system or impress anyone.
And had you read the other posts, you would have seen that Tony and others had already made their point about having a sub, without indicating that my opinion is wrong, and that I had already thanked them for their help.
