Hey folks, Im pretty new to the home audio scene. I used to be pretty into my car audio and in an old car had a modest sound system which I always enjoyed fettling with. Now I am a bit older I have taken a keen interest in my home av set up. I have so far purchased and Onkyo TX-NR515 amp and a pair of Monitor Audio Bronze BX2 Bookshelf speakers. Just with this I am very happy with the improvement over the standard TV speakers! Naturally I cant wait to add the remaining components for a 5.1 set up. My set up will be used as much for tv/movies as it will for music. Admittedly during my car days, I did enjoy my bass! I am looking forward to having some bass in my home set up, something I have never experienced before. I was looking online and particularly at the BK 200 series subwoofer. Then I got to thinking about if it would be possible to use my Resonant Engineering 12" as a driver for a DIY sub build. The driver is dual 4ohm and rated to 600W RMS. In my car I had it in a 1.8 cu ft slot ported box tuned to 28Hz. This would prob be a bit too large for my room. I don't mind going sealed to save space and to achieve a bit more control in the home audio environment. Basically I am asking for a bit of direction as to whether or not this idea is feasible and also any ideas on box specifications, amp options etc or am I better sticking with the BK200 series idea? Sorry for the noob intro post, but I am sure I will learn as I go along and I look forward to the ideas and hopefully getting some much needed bass into my set up! Thanks!
