CT Sounds is proud to introduce the hydro shallow mount subwoofer series after completing a rigorous R&D process spanning 2 years! Our goal was to engineer a 500-watt 12” shallow-mount subwoofer with a mounting depth below 4.5” that was suitable for both sealed & ported enclosures. To achieve this, we focused on the EBP (Efficiency Bandwidth Product). As a general rule, EBP < 50, is used only for sealed enclosures, EBP 50 - 100, is used for both, and EBP > 100, is used only for ported enclosures. EBP = FS/QES.

Quick Facts:
RMS Power: 500 Watts
MAX Power: 1000 Watts
Voice Coil Configuration: Dual 2 Ohm
Use Cases: Sealed & Ported Enclosures

Our 1st prototype utilized a 61.1 mm voice coil & 75 oz magnet resulting in a high QES rating of 0.89 and low EBP of 37.87. The 2nd prototype utilized a 50.8 mm voice coil & 75 oz magnet resulting in a slightly lower QES rating of 0.716 and a slightly higher EBP of 47.07. After the 1st and 2nd prototypes, we determined a larger motor assembly was needed to provide a more controlled electrical system (lower QES). This led us to invest in a custom-tooled basket (used in the final prototype) to keep the mounting depth below 4.5”.

The 3rd and final prototype uses a 61.1 mm voice coil & 92 oz magnet resulting in a reduced QES rating of 0.490 and a balanced EBP of 70.73. In testing, we ran into mechanical noise due to the larger motor assembly and voice coil in a confined space. Therefore, we invested in a custom-tooled cone to maximize the excursion capability by creating an equal distance between the cone, spider, and bottom plate. The result is a 12” shallow-mount subwoofer that is extremely responsive in both sealed & ported enclosures.

Use Cases: Sealed & Ported Enclosures

Our 1st prototype utilized a 61.1 mm voice coil & 75 oz magnet resulting in a high QES rating of 0.955 and low EBP of 37.07. The 2nd prototype utilized a 50.8 mm voice coil & 75 oz magnet resulting in a slightly lower QES rating of 0.769 and a slightly higher EBP of 46.23.

The 3rd and final prototype uses a 61.1 mm voice coil & 92 oz magnet resulting in a reduced QES rating of 0.526 and a balanced EBP of 70.04. In testing, we ran into mechanical noise due to the larger motor assembly and voice coil in a confined space.

NEW LIFE

Brought new life to my sub box!

Two of these with a 2k rms amp will do the spot.

Well made, hits hard, blows my old kicker 12 away!!! Love it!!!

The hydro 12s are really nice for the application I used them for however.....

Even though they bump very well and they sound nice I do have a larger amp than what they're capable of taking so I may upgrade to more powerful speakers in the near future. But these are some very nice twelves I love them and they sound good in my Tahoe I only have two wired down to one ohm and they sound great!

Hydro 12 BANGS

Replaced a Skar VS12D2 with a Hydro 12 2ohm. There is no comparison. None. This thing hangs with much much more expensive subs. Pair it with a CT 10001D mono amp and you’re you will seriously be impressed. My single 12 not only sounds louder but better than my friends with dual 10s or 12s by Rockford, Alpine and Memphis.
