I have been lurking on this site for a while trying to research a potential HT sub build. First off, I must say there are some very impresive subs on these pages. I doubt I will be building something to rival the dual 18 sono's I just finished reading about. But, I do hope to build something that will put a grin on my face and impress my friends during movie night.
Some history first:
I just finished building out my basement in a new home. Last home didnt have much in the way of a HT room and I kept things simple with some DIY Vifa two ways (P17 / D27) that I use for music and HT. I have the speaker cookbook somewhere from that build but ended up using Madisound to design and build the X-over. I love the sound. Not much in the way of base past 80Hz.
New room is 16 X 30 X 8 feet with and open stairwell at one end. My HT is positioned perpendicular to the length of the room with about 14 feet of wall where my plasma resides. Floor is carpeted, drywall on walls and ceiling. I am using my Vifas for the mains.
I definately need a sub or two, but also need to complete a center chanel and surrounds. I have on hand two Seas P14 RCY/TV and a Vifa D27SG-15 I bought a while ago for the center but have no clue on the T/S measurements or where to begin on a cross over. I also have two Seas / Focus P13WHOO and three Seas 19TNF/C tweeters for the surrounds.
For a Sub I would definately like to keep the price in line with the entire program so far. That means I am probably looking at a Shiva-X or a Tempest in a vented sono or box.
My biggest dilema right now is my HT layout. I have the option to put all equipment in a hall closet and have just the 58" plasma and speakers up front for a somewhat clean look with sub in back of seating area, or I can installl a low cabinet that runs the length of the 14' wall under the plasma and house equipment, center speaker, and sub /s on the ends. This will have to be determined before I can choose the Sub / center enclosures.
For the surrounds, I was thinking of just mounting the drivers on an MDF baffle and recessing them into the rear wall. I think I could make it look decent with a rounded over baffle and some speaker cloth. Sort of like a DIY wall mount. Has anyone done something like this?
If anyone can help me with the cross overs, or at least point me in the right direction, I would appreciate it. I would love to build them myself this time around. I will try to find some info on my speakers on the web for reference.
I figure the first step in this endever is to start posting and record my thoughts here. Hopefully the design will firm up with advise from this forum and I will be able to pull this off.
