I’ve tried HTIB systems from Pioneer, Polk, and Onkyo and the bass has always been a weak point, among other things. It wasn’t until I bought an entry level subwoofer from Velodyne that I realized how much more you can get when you aren’t cramming every possible feature and claim in to a turn key home theater package.
Consider the specs they are claiming, 140W power into a small sealed enclosure and achieving 19 Hz at -3...at what SPL they don’t specify but you can bet it’s not very loud if it is accurate.
I agree with the above post, you’ll be happier with something else if you are considering spending $230 on a sub.
