The significant difference would be heard in a sealed subwoofer. Usually these are more expensive and need a more powerful amp than a conventinal ported one.

is downfiring subwoofer sounds as good as ported sub in a fully carpeted room or it has to be place on room with floor tiles

Down firing Vs Ported is a strange comparison ! did yo mean downfiring Vs Front firing or Ported vs sealed ?

a sub can be ported + downfiring

i prefer a front firing one , i listed to both types before making my buying decision, a lot will depend on the acoustics of the room and the kind of enviorment the sub is being placed in along with what is the flooring it is being placed on.

The Rel Strata I use is downfiring and sealed box, and is one of the best subs for music integrated to the fronts. It does not produce boom-boom bass but rather extends the frequency spectrum to the lowest.
My room is also carpeted but I use a slab of thick granite under the sub as generally recommended by Rel and some others. This makes the bass tighter compared to what comes out without the solid slab. Try out a marble or granite slab under the sub and if it shows results, leave it there.

Trust this helps.

cheers.

I liked both ported and sealed...so I made a subwoofer with dual 8" and the enclosure in rectangular shape (really deep) with 1" MDF..I used a small port so that air can barely pass..the size of the port is adjusted in such a way that its almost sealed..but the pressure is released on precise time..its cool!!:) (Damping material used)

Ive had both front & down firing.Id say a sealed frontfiring driver would seem the way to go,but then again a ported downfiring one yields some nice lows also:)

to be honest i do not think it makes any difference below 50 Hz...but in the 50-150Hz region i have felt some part of the Bass to be directional (although theory says it below 150) and hence front firing being better from a soundstaging view
...but that very well could be perception.


In the end get the best sub (pair) you can afford to spend for...:cool:

BK Elec are the OEMS for MJ acoustics and REL (old). their subs are almost a replica of the MJ acoustics (amps and drivers !).
