You may recognize another variation of this diagram form an earlier post. I'm making some changes in my master bedroom system (larger mains and satellites, and a WDTV Live) and I have almost decided that I want to change out or supplement the subwoofer. My front-firing/front-ported TSC T250 pretty much craps out below 30hz. Good enough for most music but not much movie rumble. It's been in location "C" firing directly into the room, but I recently moved it to location "A" on top on the highboy dresser and it seems to work best there.
I contacted Elemental Designs (nice people!!!) and discussed some ideas with them. My thinking had been to put the long and very narrow down-firing/front ported
A3-250 along the wall in location "B" with the port facing toward the headboard (see arrow) and either, sell the T250, or leave the T250 on the dresser, or move the T250 back to "C" either firing toward the headboard or out into the room. I don't have room for physically larger subs at any location and the A3-250 would fit perfectly at 'B".
eD suggested that my plan would work but suggested that I go with a sealed
A5s-300 and place in location "A" on top of the dresser. He said that moving a sub up 5 or 6 feet high can make a positive difference and he recommends that solution. The 12" A5s-300 is about the same size as my 10" T250 and would fit there Just fine. It ain't pretty but I'm single and WAF isn't a big deal and it's the easiest to do.
The room and attached spaces total almost 3000cuft with the vaulted ceilings running from 9-12 feet. Usage will be 90% TV/movies and 10% music. The mains will crossover at 60hz, the center at 80hz, and the surrounds at 80hz. Both eD subs are rated down below 20hz.
Having never owned a sealed sub in my life I only know what I read. Keeping in mind the size of the room, any thoughts about a sealed 12" sub 1/2 way across the room vs a ported 10" sub next to my listening space? Any thoughts about a sealed 500w 12" having enough ummmmmph for a room that size? How about a ported 10" with 300w?
I'm leaning A3-250 because of placement and price but not if I'm immediately going to want to replace it. I may do nothing or I may place an order next week. I just can't make up my mind.
BTW: Before anybody suggests Epik I talked to them. They are for the time being a single product company and no I don't have room for an Empire.
