:wave: Hi everyone.
Based on Steve Callas's suggestion I've wandered over here to solicit some design assistance for the sub portion of my dedicated home theater construction.
Quick bit of background - for the past year or so I'm been reading various forums (here, AVS, the Cult... etc.) getting ready for when I was going to get the wife approval to build a dedicated theater in our basement. Most of my early efforts were spent learning construction, sound isolation, sound acoustic/treatment techniques. After reading for over a year the most important thing I learned was how little I truly knew. :reading: It just takes a massive amount of knowledge and experience not to screw up some detail that at the end may make or break all of your efforts. But I opted to start building anyway, figuring that since the project was going to take a year or two to complete that I'd have plenty of time to continue studying/learning/reading to fill in the major gaps. As a safety net I hired an audio/theater consultant (Bryan Pape) for input on design aspects just to make sure that I wasn't going to screw things up to badly.
So what does all of this have to do with you? Well I've just realized that I'm at a stage where I need to lock in some space construction as it pertains to building the integrated sub enclosure. My vision was that since I had a fair amount of basement space, I could allocate some of it to build a giant sub enclosure. I've looked at IB subs, but I don't think the wife would be too pleased if I defeated all of the sound proofing efforts by dumping the back waves into the rest of the house. So my thoughts were to build a sealed room that could serve as an enclosure for either a ported or sealed sub design.
After having exchanged emails with Steve and having re-read his LLT FAQ and Rodney's IB to LLT conversion thread, I've been sold on the merits of building a (S)LLT. But given that I'm sooo far behind the ball on my sub construction knowledge, I really need to get some experts to help with the actual design.
To get the ball rolling, here is a diagram of the basement project.
You can see the basic layout of the room, the location of the transparent SMX screen wall, and the rough allocated space for the LLT enclosure. I really would like to keep the costs for the sub equipment (amp and drivers) to around $2500, but could be talked up or down. Wall construction I'm just figuring to be part of the basement construction costs (just don't tell my wife).
So first question - how much space would you allocate to the enclosure. Moving that wall back and forth a few feet isn't a big deal right now as I'm still framing other parts of the basement.
Second question - equipment? Number and type of drives (FiCar Q's?), pro amp to drive them? I figure to get a BFD to help equalize the beast.
Third -design? While I may not get to building the actual thing for a few more months, getting the design locked down would be most helpful.
Anyway, I realize I'm asking a lot, but hopefully with everyone's help, I'll end up with a final product that will thrill the family for years to come. :T
best,
Michael
