If a financial issue had worked out I'd living with a new subwoofer now but alas I am not and have to wait until I purchase new speakers in April/May ish in order to purchase a new subwoofer. The speakers I'm not sure on. Later on those.. Anyway to the subject at hand. I have a large room. It's 20x25ish with a 9 foot ceiling and 2 openings which one can be shut off. The subwoofer will be corner loaded(front left) and I'd prefer a box subwoofer. My current one is an M&K Mx90 which for most folks is good but as I've lived with it a while now and heard a SVS CS+ setup, I'm wanting to upgrade. I've almost decided on a Pb2+ mainly due to my lack of woodworking skills. If I was to get some help from a friend or another local member who is better I have thought about looking at a DIY alternative. The question is.. Is this even worth the time and trouble? If that answer is yes and I can get some help then what would actually compete with the Pb2+ in terms of sheer output. From the looks of it, there is a Tumult based sub I could build but I'm a bit skeptical of its performance to take a shot at it. I was too until I heard an SVS but that is different is some ways. I would need an amp too included the the amount I'd like to spend and that would be around $1300 total. There is a DIYcable.com sub which uses a Tumult and looks an awful like the Acoustic Visions Killimanjaro which is a wood enclosure. I assume they are similar performers? For those wanting to push me towards IB, I just can't make it work in my room. I've tried to convince the SO and it aint happening so I need a conventional subwoofer. So what would you suggest?
