4 Pioneer B20s per side-What enclosure?

[tripathdude]

I want to try one last experiment before I fork out 900 dollars for the F200a. If this experiment doesn't work, I can always return the B20 drivers to parts-express.

Price for 8 drivers is only 160 dollars plus the cost for tweeters. I figure I can't lose!

Is it possible to do a BIB with four drivers per side? What enclosure will work in the corners with this many drivers? Am I nuts for trying this in a 10 by 12 foot room? It seems like it has never been done.

I figure at 19 dollars a driver, we should come up with something crazy. Give me some ideas!

Ii will be BIG. There might be room for you in the room after you get the speakers in -- might require you to remove a wall to get the forklift thru...

I would try it with a 19 Ohm driver ,not a 19 $ driver...

I plan on using OSB board so it won't cost as much compared to birch plywood. Are there any plans along these lines?

No worries about comb filtering? Folks have tried to buy multiple drivers per side from me, I always discourage them. But I haven't tried it myself.

Would a quad chang work in this situation?

Go for an OB with 5 Pioneer / side.
One in the center FR and 4 surrounding
it LP'd as a conjugate helper woofer.

Ok gimme 10

How would I get the bass output I need with 5 drivers on each side in an OB. Has anyone ever done an BIB with two drivers on the side magnet to magnet and two in the front?

Sorry but I would focus on whatever but bass .Have you considered drivers' offsets ? How are you gonna tame with four different directivity patterns and +100 different kind of reflections ? Ok ,they sit in a corner

Hi,

4 poor drivers are nowhere near as good as one (or two) good ones
especially in small rooms, the 4 times as big cabinets and +12dB
sensitivity will be of little practical use unless you have a very
low powered amplifier, bass extension will be poor for the size.

rgds, sreten.

The room will be acoustically treated with bass corner traps from floor to ceiling. I will build diffusors to spread out sound. These room treatments can be found at RealTraps - Home
