Sub at the weakest bass point in a room?

What’s really funny is no one wants to admit what I said is true. Their solution is sliders so you can fail more times before you get tired. Oh and of course how not to buy EQ and GIK. At the very least they should recommend something that might actually provide really powerful and perfectly smooth bass like put the sub in the middle of the room and sit on it.

Yes but this is only the first step. With the sub at the weakest bass point it will then become the strongest bass point. The next step is to put the sub at the new weakest bass point, making it the strongest bass point. Crawl around until you find the new weakest bass point. Move the sub. Repeat until you get so sick and tired of moving subs around that you buy a DBA.
