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.

Great sublimation paper
Size: 120g 8.5" x 14"
I like using this paper and have purchased numerous times. The one I buy the paper is a little thicker and the designs print beautiful vibrant colors.

Works Very Well
Size: 120g 8.5" x 11"
I am new to sublimation printing, and purchased this based on recommendations from multiple websites. I'm so glad I did! It transfers well onto several mediums, including shirts, totes, mousepads and cups. I've never had any jams or misfeeds, and the quality of the paper is high. I'll definitely purchase again!

Print quality is excellent!
Model: 500N STD
This is my first sublimation printer and I am so happy with my purchase! The print quality is absolutely amazing! I have made a few items and they came out perfectly! The design software and printing software that come with the printer are good but they are really slow. Before you buy, think carefully about what size prints you want to make. This printer only prints up to 8.5x14. Some t-shirt designs are larger than that. The ink is also very expensive. Versiflex ink is much cheaper. It might be worth researching the versiflex model before you commit to this printer.
