Dayton Audio IB385-8 15" Infinite Baffle Subwoofer
Looking for a similar driver more power handling more output too
Well I have been using this woofer 295-455. and has severed well for several years, but I would like something similar, maybe even in an 18" and still would like to stay an 8 ohm driver.Anything you can recommend to me?I also need something similar in terms of power, and even if it is a little more power hungry and can handle more power that is fine too.I have a Parasound mono bridged amp that is 750 watts at 8 ohm and 1000 at 4 ohms., Prefer to stay on 8.I think I have noticed lately that the woofer seems to start bottoming the voice coil at lesser power loads recently. Driver does not seem blown, no tares etc, but you can her the speaker pop lightly when loaded heavy, and it never did that before.
Fi audio makes 12, 15 and 18in subwoofers specifically intended for IB use. Alas, they are only available with 2ohm or 4ohm voice coils. If you can deal with the 4ohm load, the Fi drivers should handle significantly more power and excursion than these for marginally more money: $189 for the 12, $209 for the 15 or $239 for the 18. Fi will even *service them* should they fail, for something around half what they cost new. I've yet to hear their wares, but investigated them some months ago, and was impressed with the people who answered my questions.

what does infinite baffle mean?
An infinite baffle is the use of a driver on a baffle with the enclosure being whatever the back of the deiver is enclosed in. For instance some woofers are mounted on wood boards and then mounted with the front facing into the listening are and the rear facing say the attic. The attic will act as the enclosure. The most important thing in and IB install is to keep the front and rear waves of the subwoofer isolated from one another. There should be 100% separation.

is this for in wall use or for general ib purposes?
hey now.if i just used one of these woofers, in a regular "L" framed stand would it be good for ht use or am i better off with a sealed and eq'd (my preference in sub enclosures, if i go that route it would have to be a 10" sub)thanks in advance
The larger the baffle, the lower in frequency you can go before the back wave wraps around and cancels the front wave. That's just general acoustics, not specific to this particular driver. Since this driver is designed for infinite baffle use, it is happy without a box behind it to serve as an acoustic load, so it can work in an open baffle, infinite baffle, or dipole.You can get low bass from a smallish baffle with lots of equalization, but it won't go as loud before the driver starts to exceed its mechanical and electrical limits. This driver seems to be pretty good at large cone excursions without too much distortion, which is what you need in order to play the equalization trick. Before I mounted mine, I tried driving it pretty hard at low frequencies in open air. It held up quite well, without any buzzing or overtones, up to the point where something started rattling (at the excursion limit point).If you want to go the open baffle plus equalization route, the maximum volume will be less than what you could get from an infinite baffle. But, depending on the size of your room, where you place the speaker, and how loud you want it to be, it might very well be enough.

is this a good sub for down firing applications?
This driver will probably "work" in a down-firing application, but it is not what it is made for. The ideal situation for this driver would be to mount it in a ceiling or a floor firing into the room. Typically these sorts of installs call for multiple woofers as well. If you want to do a down firing sub, I would suggest the DVC series sub from Dayton staying in the same price range.

I will be using two of these in an infinite baffle for home theater.
They will be front firing on both sides of t.v. I will also be purchasing the Bic FH-6 in wall front speakers. Is there a problem with them all sharing the same "space"?
These will not interfere with the other in wall speakers in the same way an enclosued speaker would.

Does it matter if you use a 4 or 8 ohm powered subwoofer for a home AVR.
If it is a powered subwoofer, the woofer impedance makes no difference for the AVR.
