Last year I purchased a Polk hts 10 subwoofer. I didn't think too much before my purchase and thought of buying the best my budget could allow. Since my speakers were Polk, and I liked them, I thought Polk subwoofers would go well with them. So I narrowed my options down to hts 10 (https://www.polkaudio.com/products/hts10) and dsw 550 (https://www.polkaudio.com/products/dsw-pro-550-wi), both 10 inch. I was more inclined towards dsw, because it had more power (200 W vs 100 W) and came with a remote, and had some features like night mode, 'room optimizer' which is basically four preset dsp, four phase knob, all of which hts 10 lacked. Unfortunately the store didn't have dsw 550 (had 660, which is 12 inch) so I couldn't compare the sound. The store owner told me hts 10 is a much better sub than the dsw, even though on paper dsw looks better. I trusted him, so purchased hts 10. And so far, I have no regrets. But I wonder how it is possible for a less powerful sub to do better? In his words, hts 10 was a 'well made' sub and sounded more powerful, probably because it is front firing driver with down firing port. Is there any truth to this? Also, 100 W rms seems to be very low compared to most other 10 inch subs I see. Is there any reason a company would choose lower power for a sub(Other than making more money)?
