Hey guys, i'm having some issues with my HT setup. I use it mainly to play music, and the occasional movie.

I'm running two 12" GR Research drivers in a sealed, separated enclosure, each seeing about 1.2 cubes of air space. I'm running them on a Carvin DCM1000, giving each driver about 250 watts at 8 ohms. My receiver is a Yamaha HTR-5280.

I used this exact setup in two different bedrooms, neither of which provided very much bass. I currently have it setup in my family business' office, which is attached to my work garage, so the stereo is used mainly for music while i'm working in the garage. I'm heavy into the car audio world, so naturally I wanted something a little more extravagant than tv speakers for movies n such.

No matter which way i face the enclosure, no matter where i place it, it just doesnt produce much bass. I had the same problem when i ran a 15" dayton titanic in a vented enclosure. Because of that, i'm questioning either the amplifier or receiver as being the criminal in this case. I question the enclosure as well, but i've built a ton of enclosures, and never really had any issues with any of them as far as quality sound goes.

I have a friend who bought an off-the shelf subwoofer, which i'm sure was expensive, but it has an internal amplifier and is just a single 10 in a rather small enclosure, and it absolutely blows mine out of the water, no question. not even my 15" titanic came even close to how his sounds, and its rather upsetting.

is there maybe something about my amplifier? like it wasnt intended to drive subwoofers?

Thanks for any help, its much appreciated
