Wife and I recently purchased a new house and she is not letting me bring in my DIY sub - I know, a divorce should be in order but looks like I'm going to give in. Frankly there really isn't a good place for it anymore so I'm considering going with an Infinite Baffle design using the attic as my enclosure and mounting the Titanic to a manifold and feeding the output through the ceiling into my living room.
So what I have is a Parts Express/Dayton 15" Titanic Mark IV (but could be a Mark III) driven by a Dayton SPA500 (540w) plate amplifier.
Driver parameters: http://www.parts-express.com/pedocs/specs/295-405s.pdf
Amp: http://www.parts-express.com/dayton...er-plate-amplifier--300-807#lblProductDetails
In it's current configuration it's running in a sealed 4.5 cubic foot box (a box I originally built for an Adire Tempest - old school). It's a pretty good set up for rock music but less so for home theater - I think it starts gradually rolling off below 30-35Hz. Deep enough for most music but not so much with the lower frequencies often found in movies these days. Overall I enjoy my sub a lot but I'm now being forced (a divorce may be unavoidable) to rethink my strategy. My wife wants to do away with my sub altogether (DIVORCE!) but I don't think that is an option for me. Additionally to complicate things, I just don't have the excess funds right now to throw at audio equipment so there are no new or additional drivers or amplifiers in my plans at this point. No duals, no quads, no...
Other pertinent details:
The amp from what I understand has a 3rd order subsonic filter that kicks in at 18Hz - so low bass extension will be severely limited - may be a good thing since I only have 1 driver and don't want to kill it with LFE. Amp also has a narrow band (single) parametric EQ filter so a very minor adjustment can be made should I run into a severe peak or valley in response.
Living room is around 3500 cubic feet but also opens up to kitchen and nook.
Today my sub can easily overwhelm the rest of my system so the gains are turned down on my sub.
Remainder of my system is: Denon AVR-X2100W receiver (likely a bit over 100w/ch at 4 ohms), L-R - M&K S125, Center - M&K S150, 2 surrounds - M&K S85.
So...I have a few questions and am looking for guidance.
With all of the above, how would you expect that my sub and amp would perform in IB config compared what I am used to today? For music, for HT? I'm guessing improved low frequency response until the subsonic filter is reached. Less midbass? Less midbass may not be bad as I hear a little bit much currently.
Sound quality improve? Likely I think.
Overall output - same, less? Drastic change?
Any design considerations I should be looking at? Well besides the obvious of making the manifold large enough to accommodate 1 or 3 more drivers for future growth
Basically I'm just trying to figure out IF it's worth the time and effort of doing the work or will it be a huge fail.
