Sound Ordnance's B-8PTD powered subwoofer is the latest version of the B-8PT, one of our all-time best-selling compact powered subwoofers. Sound Ordnance built this new version to perform even better than its predecessor, putting a cool-running 125-watt amp and a rugged aluminum 8" sub in an extremely compact, solid ABS plastic enclosure,so you get years of bass satisfaction. This all-in-one unit frees you from having to deal with a separate sub, amp, and enclosure, saves you cargo space, and simplifies your wiring requirements. Whether it's mounted under your car seat or in an out-of-the-way location in the cab of your truck, this little workhorse will surprise you with its impressive bass and its ability to mesh perfectly with the rest of your system. This compact sub delivers strong bass without taking up much space. Big bass from this tough little sub A 125-watt RMS Class D amplifier powers the sub and lives on a compact circuit board mounted inside the enclosure. The sub's stiff 8" aluminum cone holds its shape even when playing hard, helping to keep the lowest notes clean, and ensuring a long life for the sub. You can adjust the low-pass filter, variable phase control, and bass boost to get the B-8PTD sounding perfect in your vehicle. Preamp- and speaker-level inputs allow convenient connection to just about any system, even a factory stereo. The molded ABS enclosure houses a 125-watt amp and a tough little 8" sub. Good design helps The B-8PTD's tough outer casing of molded ABS plastic serves as the sub's sealed enclosure and can withstand some pretty extreme internal pressure changes with no reverberating or buzzing. Sound Ordnance conveniently located the neat, clean, easy-to-understand controls on one side, opposite all the connections, so you won't get tangled in wires as you tune your bass. Review: Good little unit - Nice compact unit. Easy to set up (as easy as setting up a sub can be, at least.). The audio isn't window rattling. It won't wake the neighbors. However it rounded out my Sony aftermarket head unit very nicely and added a little thump and bass that didn't exist after I installed the new head unit. Well worth the price, in my opinion. Review: Lovin' it!!! - I'm impressed!!! I don't normally write reviews but so far I am very pleased with this little sub! I see what all the good reviews are about. Surprising amount of bass from such a small box! It feels tough and I am definitely amazed at the tight, clean bass this produces once dialed in. It won't break any windows or reproduce ridiculous low frequencies, but it pretty much adds just the right amount of low end to the music inside my TJ. I installed it under the rear seat of my 99 Jeep Wrangler TJ (right next to my 300 watt Jensen amp that's running the Kickers in my sound bar) and it fits perfectly. I worried it wouldn't be happy facing directly into the bottom of the rear seat (literally right up against the bottom of the seat), but it works out great! Happy!!! ## Features - enclosure with one 8" woofer - built-in Class D amplifier (125 watts RMS) - preamp- and speaker-level inputs - wired remote control included - Support by Crutchfield℠ ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00IF9IIWK | | Additional Features | Bass Boost, Protection | | Antenna Location | All | | Audio Driver Size | 8 Inches | | Audio Driver Type | Dynamic Driver | | Audio Output Mode | Stereo | | Best Sellers Rank | #162,607 in Electronics ( See Top 100 in Electronics ) #867 in Car Component Subwoofers | | Brand | Sound Ordnance | | Built-In Media | wired remote control, cables | | Compatible Devices | Desktop, Laptop, MP3 Player, Projector, Smartphone, Tablet, Television | | Connectivity Protocol | Bluetooth | | Connectivity Technology | XLR | | Control Method | Remote | | Controller Type | Corded electric | | Customer Reviews | 4.2 out of 5 stars 90 Reviews | | Enclosure Material | ABS plastic | | Global Trade Identification Number | 08550810025486 | | Is Waterproof | FALSE | | Manufacturer | Sound Ordnance | | Material | ABS plastic | | Model Name | B-8PTD | | Model Number | B-8PTD | | Mounting Type | Plug Mount,Wall Mount | | Number of Items | 1 | | Power Source | Corded Electric | | Speaker Maximum Output Power | 125 Watts | | Speaker Size | 8 Inches | | Speaker Type | Woofer | | Specific Uses For Product | Vehicle | | Subwoofer Connectivity Technology | Wired | | Subwoofer Diameter | 8 Inches | | Unit Count | 1.0 Count | | Warranty Type | Limited | | Woofer Diameter | 8 Inches | ## Product Details - **Brand:** Sound Ordnance - **Speaker Maximum Output Power:** 125 Watts - **Connectivity Technology:** XLR - **Audio Output Mode:** Stereo - **Mounting Type:** Plug Mount,Wall Mount ## Images ![B-8PTD 8" Powered Subwoofer - Image 1](https://m.media-amazon.com/images/I/71e+RXpM-DL.jpg) ![B-8PTD 8" Powered Subwoofer - Image 2](https://m.media-amazon.com/images/I/61XL96xVIXL.jpg) ![B-8PTD 8" Powered Subwoofer - Image 3](https://m.media-amazon.com/images/I/61+gDedOKDL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good little unit *by J***N on April 28, 2022* Nice compact unit.
