Not sure why the website shows freq. response as 30hz to 150hz (-10db) That's crazy talk! The 12 inch measured down to 20 hz and this one measures down to 15 Hz! It's a super deal!!

1) Meant for music.
2) Bro wants a sub for 250 bucks that beats out SVS in raw performance.

Take your pick on which argument you sounds best

You're probably thinking of their Monolith model.

I just did. Speedwoofer 10E for $315 right now: https://rslspeakers.com/products/...woofer-10e
It's an okay sale on a great sub with free shipping. Record prices were ~$270 years ago, $299 recently. I didn't want to wait to replace my failed DT Supercube 2000 office sub any longer.

People overthink subs, all subs sound horrible without DSP room correction. It doesn't matter how much the sub costs.Those anechoic measurements only validates the "power" they're claiming.Take any $1000 subwoofer, put it in any house, instant peak around 60-100 hz, instant trash.
Also, what matters more when using DSP is its actual maximum undistorted SPL at each frequency. A "flat" sub which is less capable if its max at 20 Hz is 10dB lower than another "non-flat" sub.

Well pretty much all AVRs offer room correction, you can even add it.

If your $1k sub sounds like trash, sorry but it's not the sub, that's likely user error.
