I just got my sub installed and samson amp hooked up. To tell you im not that impressed as people made it out to be. Im not too happy. The Bass isnt that "BIG" I got my samson amp turned up all the way and the gain on my yamaha reciever up all the way. Its not that powerful. I mean I have a powered 8in mirage sub and that sounded good it just bottomed out if i had it up too loud. At least my mirage went decently low and still punched high. Half the stuff I play music or DVD I can barely hear the sub unless its a real low bassy part. I mean unless this is the way its suppose to be I dont like it. I like to hear my sub on everything. I admit that the svs sub hits some lows my 8in didnt do. But Not all movies and music have that lkow of a hertz. Now if the samson sub had a hertz filter so i can adjust I would be happier. I played dvd's and music cd's at the sametime one at time on the svs and my mirage. Not much difference if it was on a low-medium level. Now when i crank it up loud on my reciever the svs shines but who the hell listens to tv, music movies way past half way? I dont. I listen to my dvd's pretty loud but not half way on the volume knob. I have to have hear to really make big notice on my svs. So my conclusion on my new svs sub is to send it back. This isnt for me. I might be happier with a 10in powered sub. This svs sub I feel like doesnt stay in the higher hertz range. Too much on the low side. My brother cam over and was like whats the big deal of this sub and amp? Needless to say I felt kinda embarressed. I mean geez I had the samson amp gain all the way up along with my reciever and was expecting this to hit hard. I really feel that if I had a powered 10 inch sub it would be almost the same. I can live without hitting the "25hz" range.
