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.

Hydro 12

Once I received and unboxed my Hyrdo 12 I was literally blown away by the quality of this affordable shallow mound sub. I am currently breaking it in and will update my review after the break-in period. So far I am very pleased with the sound and quality.

MY THOUGHTS

A little more help while ordering would be nice.
I ordered two subs an amp and wire kit along with a bass control knob .
Come to find out my amp came with a base knob and my amp is not really compatible with my subs , wish I would have know that I could have ether changed subs or amp.

Costumer service was grate with quick responds.

I have not installed them yet. But I have had the 10 before. and they were great.

Nice

2021 superduty with a Single 12” Skar audio under seat box with the ct 700 mono block amp and lc2 line out converter and it absolutely slams. Excellent customer service also I highly recommend CT Sounds.
