The12 SUB PRO PASSIVE SEALED SH with its sealed cabinet concept offers a rock-solid bass sound from the smallest of dimensions, easily integrable in restricted installation situations. With its shallow depth of 210 mm (8.27”) and exceptional 12” woofer, it can deliver the kind of tight, punchy bass and impressive dynamics that many would like from their modest home theaters or media rooms, all while tucked away in out-of-the-way locations.

The12 SUB PRO PASSIVE SEALED SH shares the same core design advantages the entire range of ASCENDO subwoofers feature - extremely low distortion to reproduce the finest details with the highest dynamic range to meet the content transients without compression, but perhaps more importantly, a linear response from bottom to top to allow for exceptional integration with the main and surround channels.

Gorgeous Tiffany-Blue & Perfect for Travel
I absolutely adore this little jewelry case. I don’t have a huge jewelry collection, so the size is perfect for me. It keeps everything organized without being bulky. The zipper feels very sturdy and smooth — not flimsy at all. And for anyone who loves Tiffany’s blue… the color is almost an exact match. I can set it next to my Tiffany box and it’s nearly identical. It’s such a pretty, luxe-looking shade. Highly recommend.
