Designed to be at home in the competition lanes or playing your favorite music, the U Series is the premier “standard suspension” woofer in the Sundown lineup. A double-stacked 9.4-inch wide ferrite magnet system is coupled to a thick top plate. A thick set of shorting rings are used inside the magnets and on the pole cap, smoothing out frequency response while doubling as a heat sink and airflow guide. A custom, substantially thicker aluminum frame was designed specifically for the U Series, equipped with heat dissipation ribs. The U v.2 motor also features an extended pole piece to keep the coil under perfect control under high stress. The coil temperature is kept in check via a high-velocity solid pole / machined pole channels arrangement and a series of 16 direct air-gap vents in the back plate.

    Mid jeans. Not bad but not amazing
    The button is super wobbly and feels like itll break at any moment. The zipper quality also isnt great even when im not wearing them the zipper cant go above like 80% when I wear them itll slowly unzip if I twist or turn my body over a few hours. There's also not a lot of room for your bits so maybe go a size up. Other than that rhe material is comfy and has a bit of give so unlike other skinny jeans you dont feel restricted. The color is also super vibrant and lovely. Im not gonna return them unless the zipper breaks but idk if ill buy another pair if the button is like this.

    Nice suit
    The quality is really good. My fiance is planning on getting married in this. The only thing Is the pants is standard size so ofcourse it's not one Size fits all. However it fits well but it's too long for him and we might take in the legs alittle. Otherwise it's good. The light blue is gorgeous. Nice. It's worth it.
