I've been toying with the idea of installing an infinite baffle sub/manifold in my ceiling, would this driver (or a pair of them) work well for that? I know how to construct and install the manifold to avoid vibrations etc... just not sure on what specs to look for in a driver.
This is an awesome driver, please don't misunderstand. It will rattle you brains out with the SPA500 plate amp. The 900W is not a maximum, its RMS, you could probably feed it with a 1500W pro amp safely.Installing an IB sub is really great! Spousal approval is a non issue. Pick a good long weekend and do a really clean install, put nice white covers over the parts that show in the room... They may never even notice. There is also that really deep low end, and awesome clarity to aim for. Honestly though I would suggest 294-455 as a better choice for several reasons;1. It is made specifically for the infinite baffle configuration. Dayton built it with more Xmax and a tighter suspension meaning it will retain more precise control and produce less distortion.2. It is 15", which fits nicely into the space between your ceiling joists (16" centers in most construction). Installation is much easier even if you do use a manifold, though you wouldn't have to. take out a piece of the drywall, replace it with MDF, center the driver holes in the voids between the joists and you have a very strong baffle. Glue and screw to the joists, many screws.3. At this price you can have two of the IB385, which means a very similar cone area, (to this RSS460,) with more Xmax. This results in a higher volume of air being displaced with only 700W. Unless you are trying to match to a pair of 1000W mains, the SPA500 will give these more than enough power to rattle your brains as well as give you more than enough headroom if you are trying to integrate to mains up to 300W.the idea here is that, while this, (the RSS460,) is an awesome driver, it is geared more towards a vented enclosure of moderate size or a high power sealed application. When it comes to IB bass, swept volume is really the king, matters more than just about any other parameter of the speaker.. A pair of the IB385 has more than a single RSS460. Vent sizes and all kinds of other parameters of the speaker system are based on how much air the cone moves with each stroke. You can get more, for the same money AND have an easier time with installation AND feel compelled to pay less for amplification AND the truly big and awesome thunder that only IB subwoofers can provide!BTW four of either of these could be linked series parallel to net a 4 Ohm load. the same economics apply, no extra amplification is needed, and you get a 3db boost. You could then put one at each corner of the ceiling, preferably inside the perimeter by 25%, i.e. in a 12' by 15' room, you would put them 3' from the 15' wall and 5' from the 12' wall. This has to do with room resonances at low frequency, the bane of audiophiles everywhere! Its complicated, but you won't need to worry about it.
