Subwoofer On Carpet
- (subwoofers) loudspeakers that reproduce lower frequencies, typically 20 Hz - 200 Hz.
- A loudspeaker component designed to reproduce very low bass frequencies
- a loudspeaker that is designed to reproduce very low bass frequencies
- A subwoofer (or simply "sub") is a woofer, or a complete loudspeaker typically between 8" and 21" in diameter, which is dedicated to the reproduction of low-pitched audio frequencies (the "bass").
- A large rug, typically an oriental one
- A thick or soft expanse or layer of something
- rug: floor covering consisting of a piece of thick heavy fabric (usually with nap or pile)
- form a carpet-like cover (over)
- A floor or stair covering made from thick woven fabric, typically shaped to fit a particular room
For more than 50 years, midrange and high frequency horns have been the hands-down choice for movie theater sound engineers. From the softest whispers... To the highest impact sound... Hrn drivers have no equal when it comes to clarity and dynamic range. The BIC Formula Theater Series carries on the legacy of the first Formula Series introduced in 1973. They offer an output capability of up to 116dB (live rock band levels), while offering refinements that surpass all of its predecessors. Injection molded long throw woofer; BASH designed amp. Adjustable crossover, volume and auto on/off. Speaker level and RCA inputs. Frequency response: 25Hz-200Hz. 15" W x 17" H x 18 1/4" D. Sold individually.
The 12-inch, front-firing F12 powered subwoofer from BIC America incorporates a high current 475-watt peak amplifier designed by BASH Technology in combination with a 12-inch injection molded long-throw woofer. A patented BIC "Venturi" vent eliminates port noise, which is often heard from other subwoofers especially when playing demanding music and videos. The F12 also features an adjustable crossover, adjustable volume control, automatic signal sensing, high level inputs, and both Dolby Pro Logic and Dolby Digital/DTS inputs.

ok... first things first: there is a little bit of wide-angle trickery going on here, but it's not as bad as you might think.
this is my old sub, which is being replaced by the new one under construction. i salvaged the two MTX blue thunder legend 10"s from a car box that originally had three of them (the voice coil melted on the third). these subs have served me well for almost ten years. they look a little ratty, but i kept them. maybe they'll find new life in some other project down the road.
the box measures 10" x 16" x 78". that means it's 6.5 feet tall. that means it's taller than i am (i'm 6'4"). there were 165 screws on just the outside, plus another 15 or so internally that i couldn't remove. it's volume is roughly 7 ft^3. the ports are 1.5" x 4". i don't know what the tuning frequency is, but it's LOW. like, maybe below 20 Hz. it's highly efficient, and would reach THX spec with maybe around 50-60 watts. it weighs, i'm going to guess conservatively, about 200 lbs. it took me around 20 hours to build, straight through, and one hour to dismantle. it's built the way i build all my sub boxen: with a bead of liquid nails at the joints, and overkill on the screws. i still remember having to drag this up the narrow basement stairs at something like 4:00am the night i built it. and after that, i still had to wrestle it into position. it is a beast, and it doesn't move well across carpet.
you can probably understand why it's being replaced. it's a great performer, but the size and weight make it completely impossible for any sane person to live with. it also looks like rat ass because i didn't care about making it look professional when i built it. the new sub should equal it in performance, and will definitely look more presentable. and while the new one is big, it's not THIS kind of big.

You can see the color real well now. Notice the speaker connection plate? It's not by chance that I put it there... It allows for a perfect place to connect the front half of the mod to the back half, and allows me the ability to reach the subwoofer db dial from the seat.
Also I found a pretty decent seat cover to use. Black with barbed wire and skulls. Works for me!
I also forgot to mention that since I split the bass speaker from the circuitry, I was a bit worried about keeping it cool, as the bass thumping gave it airflow through the box port. So if you notice right underneath the mousepad is a cut-out inlet, and underneath there is a 80mm fan pulling air through that inlet, and across the soundboard heatsink. It then ports the exhaust out the handle holes on the other side.
I should also note that the raised section you see on the floor in front of the seat is a strip of 7# carpet padding I added since I kept putting my feet up there when the seat was all the way back. The entire floor of the front section of the mod is also padded, except where the pedal assembly is, allowing the pedals to look built in, rather than just bolted to.
