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.

Quote from xtp :
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.
