Hey PN! Been a minute.
Working on a paragon 25' lately, with the factory wake subs blown. Here's some pics for those of you that are interested. Driver is a 12tw3-d4 2x, which presents a 2 ohm load on an MV600/1. Strangely JL didn't design it for a 2 ohm load, so each sub sees around 150 watts RMS. These are being replaced with dual 8 ohm models to get a 2 ohm load on the amp for a slight bump in power.
Boat was a 2022. The factory subs were rusted together at the coil and magnet, we drained about a gallon of water out of the ported side. the sealed side also had some water in it, but only a couple of ounces.
JL Audio does not give technical support any details of the tuning or volumes of this enclosure. It's a single reflex bandpass enclosure. Hope to get some time to measuring the volumes of the sealed and ported sides. Ports go into bilge blower accordion style tubing, which i guess is specified to a certain length by JL to Nautique. JL also does not specify the model number of these subs, just that they are 12".
Our plan is to install the 12tw3-d8 replacements, pull the gasket tape, and reseal with 3m 4200 in black then reinstall the enclosure. We will likely adjust the high pass/subsonic filter to a 48 db slope (max in JLA Tun) to around 28 hz and test and see how the sub selection changes the sound. With these enclosures tuning is very important.
if anyone has any questions, LMK.
