Air Space, 35 Hz Tuning, Car Audio, Compact : Electronics Review: Loud - Combined with a Rockford punch 3 wired at 2 ohms it hits so hard it's unbearable after one song better hope you have a bass knob unless u wanna say goodbye to your ear drums and your dashboard at the same time Review: Perfect Box once you seal it! Paired it with a T5-122 Tarantula & a Taramps HD2000.1 - This box is great, but you MUST seal it yourself. I paired it up with a Tarantula T5-122 sub. This sub recommends tuning at 30ish hz but it QUAKES in my single cab Chevy. I’m pushing it with a Taramps HD2000-1ohm amp. I adjusted to amp to respond between the recommended Hz for the sub and the 54Hz that the box is tuned at. I have my gain and boost at 1/3 max and it’s hard to breathe when I hit max volume on my stereo. Perfect setup for less than $500. I haven’t broken in the sub yet so I’ll update this review later. They say 3/4 mdf but it seems more like 5/8ths, if you don’t seal the box it will rattle and crack the Berliner coating. Overall this thing has impressed me. Worth the $$ and with the right sub it POUNDS. Do the research, the T5-122 was the best sub I found in my price range to fit the tune of this box. ## Features - Triangle Ported Design: Engineered with a vented triangle shape that improves airflow and reduces distortion, this enclosure delivers louder, deeper bass in your car audio system - Spacious 2.2 Cu Ft Air Volume: Offers ample internal air space to support high-performance bass output from most 12-inch subwoofers, helping you get the most out of your audio setup - Durable Bed Liner Coating: Built to withstand wear, tear, and vibration, the rugged spray-on bed liner finish resists moisture and damage, making it suitable for high-impact audio setups - Precision-Built: Made from dense, 3/4-inch medium-density fiberboard for long-lasting strength, with spring-loaded terminals for secure wire connections and clean signal transfer - Universal Fit for Most 12" Subs: Cutout diameter of 11 inches fits standard subwoofers, with a tuning frequency of 54 Hz to enhance low-end response and create punchy, hard-hitting bass ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01CD9CVA2 | | Antenna Location | For Car Audio Systems | | Audio Driver Size | 12 inches | | Audio Driver Type | Dynamic Driver | | Audio Output Mode | Mono | | Best Sellers Rank | #42,390 in Electronics ( See Top 100 in Electronics ) #50 in Car Subwoofer Boxes & Enclosures | | Brand | Q Power | | Built-In Media | Enclosure | | Color | black | | Compatible Devices | Car Audio System, Laptop, MP3 Player, Smartphone, Tablet | | Compatible with Vehicle Type | Car | | Connectivity Technology | USB | | Control Method | Touch | | Customer Reviews | 4.5 out of 5 stars 380 Reviews | | Enclosure Material | Wood | | Frequency Response | 54 hertz | | Is Waterproof | FALSE | | Item Dimensions D x W x H | 14"D x 22.7"W x 16"H | | Manufacturer | Q Power Inc. | | Model Name | RQ12TB SINGLE | | Model Number | RQ12TB SINGLE | | Mounting Type | Tabletop Mount | | Number of Audio Channels | 2.2 | | Number of Items | 1 | | Power Source | Corded Electric | | Speaker Maximum Output Power | 600 watts | | Speaker Size | 12 inches | | Speaker Type | Subwoofer | | Specific Uses For Product | For Car Audio Systems | | Subwoofer Diameter | 12 inches | | UPC | 813177023907 | | Unit Count | 1 Count | | Warranty Description | 1 Year Manufacturer Warranty | | Warranty Type | Limited | | Woofer Diameter | 12 inches | ## Product Details - **Audio Output Mode:** Mono - **Brand:** Q Power - **Connectivity Technology:** USB - **Frequency Response:** 54 hertz - **Speaker Maximum Output Power:** 600 watts ## Images ![QPower Single 12" Triangle Ported Car Audio Subwoofer Box, Bed Liner Finish - Image 1](https://m.media-amazon.com/images/I/71fpkcCxtaL.jpg) ## Questions & Answers **Q: Would this work with JL w6 12?** A: Will work with any 12 hits hard great box **Q: Will this fit In behind a 3rd row seat 2008 Escalade** A: Yes **Q: What's the actual tuning frequency? on here it says 54 hz but on rockville's site and a few others state it's 35hz** A: Yeah my thoughts too.
