[QUOTE=Hopinater;58677242]I think you'll be happy with the 18". After hearing 18" subs and 15" subs side by side I found the overall impact of the 18" subs to be more intense. They just plain sound different, they seem to burrow right into your soul a little deeper.
You sold me 😊. I have one of the original S1500 and it has been a great sub. The sealed 18 has been on my wish list since the day they were introduced. The new and improved woofers put it farther up the list and reading positive reviews from owners such as Hop put it over the top.
The S1812 will replace my V1500 in my HT system. I am not very astute on all the tech stuff, I just like reasonable bass. We don’t listen at extremely high master volume, so I am thinking the S18’s lower output under 30 hz will not be a significant issue. If I am correct, the S18 will be stronger above 30hz than my V1500 and overall sound quality with the new woofer will be superior.
I originally ordered the S1512 because I wanted to reduce the footprint and weight of my system components. Guess I didn’t do too good of a job on that front, but that S1812 kept calling my name. I sold the wife on the fact that it is 5 inches shorter. Overall weight is close to break even between the 1500 and 1812, as the new woofers are a little bit heavier. This may be my last HT woofer, so I didn’t want to buy the S1512 and regret not getting the 1812. I am however paying close attention to that Value 12 that’s due out. I have a 2 channel system in a small sealed office that includes an SVS SB-12 NSD. It does a decent job in that room and system, but I am thinking the new PSA 12 will likely be much better. Thanks for all the advice guys. This forum is a great resource.
