Hey all.. After looking at a bunch of posts/links and all that jazz.. Since I am totally new to all this stuff. I guess I basically need, well, some basic question's answered. I din't see a "beginners sonotube section", I woulda posted there. I have a 22x25' room with 8' ceilings.... I will have an Onkyo 696 receiver.. I will have the DIVA 4.1 package loudspeakers.. I will have a Pioneer SD643HD5 RPTV I will have a sub! Just don't know what yet. I was 1st going to get the Adire Dharman for about 600 bucks, but then looked at the forums and I wanna build my own, the cost maybe cheaper?, the satisfaction will be extreme! So again, basic question, since I don't have any idea what I need. I believe I want to build the Tempest with Sonotube, I would think this would be a good compliment to my other "stuff"..but, will room gain make this boomy? Do I have to use an EQ? Is there an easy answer to what exactly size I need to build to suit my room size? I downloaded the software from Adire's site to help me out, along with the white paper. Is the design I need for my application in the white paper? Looking for the easy way out Is anyone building the plate amp into it, and if not, where/how do you put the amp? I will be using the 250amp from the Adire site... I am mostly looking for H/T but want good music also.. I am sure I will have a zillion more q's, but I am reading posts/links 1st trying to learn and not bother ya'll to death! Thanx so much..
