PSA XS30 graphed in room.

[Bear123]

Flat to 10 Hz. Thought this might be helpful for anyone considering a sub in this price range. I have a 2525 cu. ft. room with an open stairwell, so it is not a sealed home theater, just my living room. The output down low for movies is very good, and the mid bass output is incredible. I have a little Polk next to the couch to fill in a 50 Hz null. Plan on replacing the Polk down the road. Anyway here is how the XS30 looks in my room:



There is no eq applied below 30 Hz(actually did a cut at 25), so the bottom is flat all the way down from room gain. The reason the chart is title sealed room is that I have two 5' french doors that are normally open in my living room. I can close them for movies. FR is flat down to 14 Hz or so with both sets of doors open.

What does the unsmoothed graph look like?

About the same, just slightly more squiggly. What we hear is actually better represented by a 1/6th graph, but I like to use 1/12th for the most detail while smoothing very slight irregularities that don't need wasted eq. Makes it easier to see a region that is actually big enough to merit some eq. I use unsmoothed when placing and adjusting phase and distance, but for eq purposes I use 1/12th. You don't want to apply eq to an exremely sharp little dip or peak that you cannot hear.

I'm aware, but for those that know how to interprete these graphs I'd rather see unsmoothed.

Had to switch computers to make the graph didnt have it saved. Here you go. Hoping when I add a more comparable sub I can smooth things out even more with less eq.



Considering this is the sub I am using to help smooth out the response, I am pleasantly surprised by the outcome:

That graph makes me go, "giggity giggity".
