SVS has offered owners of their sub a driver upgrade, and many have upgraded, and offering their old drivers for $40 plus shipping (the credit that SVS is willing to "buy back" the old drivers), but many don't want to pay for shipping, so by selling to other people who'll foot the shipping bill, they recoup the entire $40 for their drivers.
Well, I bought one of these old SVS drivers to retrofit into an old 2.5-2.75ft^3 ported enclosure that was built for a Shiva.
Here's 4 photos of the SVS "upgrade" process:
Photo 1: Here's the raw SVS driver (I took off the rubber surround ring in order for it to fit the cutoff from an old sub enclosure that was made for a Shiva 3 years back by another member here).
Photo 2: Here's the old box sans old driver. You can get a glimpse of the extensive plumbing job I did on the port.
Photo 3: Here's a closer shot of the innards of the box. The original port was about 8" long, but I went overboard and used some 45 degree PVC pipe bends to get the port length around 22"-24" long. It was not fun getting all that extra stuff in that box. What it's tuned to? I'm hoping down in the low-20Hz range. I'll play around with the calibration and measurements later and find out.
Is the porting ideal? No. I'm just trying to make lemonade with the lemons I've got on hand.
Photo 4: Here's the subwoofer put back together with the SVS driver in place.
I had to go buy banana plugs for the driver because I couldn't get the 5-way binding posts on the drivers to screw down on bare wire - no big deal. The driver is supposed to be recessed, but the outer recessed driver rim is just too tight, and I basically have the driver screwed in on half of its right side, and wedged in, hammered in, and screwed in on the left side. I the did the tissue test and couldn't find a leak on the driver "installation". I'll have to mess up the front baffle to get the driver out of there if/when I decide I need to fix this problem. I have a cover for the driver, so with the cover on, no one is the wiser.
I don't know how "ideal" this enclosure is for the driver, but I calculate internal volume to be around 2.5-2.75ft^3, which is pretty close to the old SVS 25-31 CS model.
