 Physically moving that huge and heavy box into place. |
True, it will be heavy, but nothing that can't be handled and it will only have to put into place once.

Yes... it will need proper bracing, no doubt. Rodny will be helping me and he's really good at it... not that he's built one this big, but together I'm sure we can handle it.

Keep in mind I will have the levels matched and I have a pair of Plus/2's. They are crossed over at 80Hz and these in the rear will be crossed over at 60Hz.

Phase-related response errors. |
I've not experienced any problems with this thus far with the rear sub at 0 degree phase. I've tested it in 30 degree increments up to 180 degrees. I don't see how swapping subs will change this, but maybe I don't understand something I need to understand.

Have you considered placing the enclosure(s) in the garage firing through the wall into the HT?
You can have two widely spaced enclosures for a better bass spread without cluttering the HT.
Much greater freedom in design without worrying about finish. |
That would be ideal, but I can't take up the room in the garage. The attics stairs fold down next to the outside of that back wall, so anything protruding into the garage would be a nono. Plus it's a small hallway to an outside door... I don't see that working, even though it would be nice. What would be even mo betta would be my wife allowing me to extend the room all the way through that hallway, but it would require moving the stairs and a whole lot more I just really don't wanna get into.

If the box is ported at one end with the driver at the other the physical separation of the sound sources might prove problematic for the nearest seats. Quote: steve nn wrote:

There will be two drivers and the plan is to locate them 1/4 distance from each end...
It would seem like the simple solution to this is two discrete enclosures with a port for each one.
I believe Stevecallas stated I would need at least 260 effective liters and a 6" diameter port that is 31" long. Would this be correct for a 13Hz tune?
Speaking of tuning to 13Hz... is not the purpose of the port to augment the tuned frequency? If so, how is anyone going to localize 13Hz?
At any rate... would sealing off each driver for two discrete enclosures be the best solution?
