Subwoofer Specifications

Subwoofer Size
Refers to the diameter of the subwoofer, measured in inches.
8"
Voice Coil(s)
Dual voice coil subs have more wiring flexibility than single voice coils subs; however, single voice coil subwoofers provide easier hookup options for wiring multiple subwoofers in parallel or series. You may also run a dual voice coil (DVC) sub in parallel, series, or combination. A quad voice coil has four voice coils and is equal to two dual voice coil subwoofers as far as wiring goes.
Single
RMS Power Handling
The RMS power is the amount of power the speaker requires to operate safely and properly. RMS Power Handling refers to the amount of power a speaker can handle on a continuous basis. We recommend powering your speakers or subwoofer with 80%-120% of its recommended RMS rating. The RMS power handling specification is typically rated per speaker unless otherwise noted.
80 watts
Woofer Surround
A speakers surround is part of the suspension system. The surround protects the cone and prevents it from being displaced as it flexes out from the basket. It is usually made of a durable material like treated foam or rubber in order to withstand the strenuous job of producing bass frequencies.
Rubber
Woofer Composition
Lightweight woofer cone materials are essential for efficient operation. Poly cones produce exceptional sound and are sturdy against various changes in temperature. Paper cones are very efficient, and when treated for moisture resistance, will perform at a high level. Poly refers to polypropylene, which is thermoplastic or fibers that are polymers of propylene. IMPP refers to injection molded polypropylene, a commonly used process and material in speakers.
Fiberglass
Sensitivity
An efficiency or sensitivity rating tells you how effectively a speaker converts power into sound. The higher the number, the more efficient the speaker and the louder it will play with the same input power. An efficient speaker helps you maximize your available power. Most sensitivity ratings measure the speaker's output with 1 watt of input, 1 meter from the speaker. Some speakers' sensitivity is measured with 2.83 volts of input, instead of 1 watt.
 
Efficiency (1w/1m) is not an accurate indicator of a subwoofer's output capability and should not be used as a comparison to other speakers or subwoofers to determine which one is "louder".
90 dB
Frequency Response
The range of frequencies the speaker will reproduce (lowest frequency to the highest). Bigger is better, meaning the wider the range, the better. The optimal range is 20 - 20,000 Hz (which is the range of human hearing).
20 - 150 Hz

Enclosure Specifications

Box Type
Represents the style of the enclosure. Be sure to purchase the appropriate enclosure type and internal volume that will be compatible with your subwoofer's recommendation.

Sealed - Sealed boxes are those that have no holes or vents in it. The only hole in a sealed box is where the subwoofer is installed. Smaller sealed boxes require more power than a larger sealed box. They provide a tight, accurate bass, while the larger sealed enclosures provide a "boomier" and louder bass.

Ported / Vented - Ported/Vented Enclosures provide an even boomier, louder bass, but less accurate then a small, sealed box. Ported enclosures typically require more airspace per sub and also less power output from an amplifier to perform correctly.

Bandpass - Bandpass enclosures make subwoofers perform efficiently, but loose. The bass is not as "boomy" as a ported enclosure nor as punchy as a sealed enclosure. Bandpass enclosures work well with lower to mid-level subwoofers.
Sealed
Number of Subs/Speakers
This value represents the number of speakers or subwoofers that the enclosure accommodates.
1
Box Style/Shape
The box style or shape refers to the actual shape of the box. Square and rectangular boxes are straight-edged boxes on all sides, whereas hatchback and truck style enclosures feature an angled front or back design that allows for installation in places short on depth such as single cab pickup trucks. You can also use such enclosures in hatchback cars or other vehicles where space is a premium. Tube and cylinder shaped boxes were made popular by Bazooka and are a great option for those looking for a nice amount of bass without sacrificing lots of space. They may even fit in locations that slim truck boxes cannot fit in. If the enclosure is vehicle specific, we encourage you to read the product description to find out which vehicles the enclosure is made for.
Square/Rectangle
Height
The height of the item, measured from top to bottom, in inches.
2-8/10"
Width
The width of the item from left to right (side-to-side) measured in inches.
9-8/10"
Depth
The front-to-rear depth of the item, in inches. If the item is angled or slanted, this value is the bottom measurement.
13-1/2"
Number of Terminals
The number of terminals the enclosure has. Each terminal represents 1 positive and 1 negative.
1
Box Exterior Color
The color of the enclosure's exterior/outer finish.
Black
Box Finish
The material used on the outside of the box. Most boxes are carpeted to prevent exterior scratches; however vinyl is popular as it can often be color-matched to a near exact look of your leather factory interior.

Toyota Tacoma

February 5, 2013

Fits under the seat of my Tacoma so it takes up no important space in the cab. Sounds great and adds more than enough bass to the small speakers in that truck. Install was easy as well.

Great value

January 10, 2013

After getting tired of seeing my Big Bro tossing money out the window trying to find a sub that mixes well with the factory SQ system in his Benz., I brought and installed this one for him while he was out of town. I drove his car for a week he was gone and loved it. once my brother returned home the first thing he notice was the nice clear non muddy bass he was looking for and exactly what was missing from his system. It was simple to install. I mounted in the trunk. He loved it so much he told the Benz Car Club his in about it and they all want one. So thank you NVX for making such a great product

Got my money's worth and then some.

September 20, 2012

After looking at the Focal model which literally is exact same except for a plug for VW/BMW (I have a Ford Pickup), I felt compelled to give this one a shot. Thankfully I did because I have $300 in my pocket for something else and money isn't exactly flowing for me. Anyhow, back to the product. The bass is exactly what was missing from my system. It was simple to install. I have it vertically mounted behind the seat. It runs for a few hours a day during my commute and I haven't had one hiccup. I am really happy with the product, the service at Sonic was excellent and my trek to work is much more enjoyable.

The little sub that could

April 26, 2014

I installed 8 polk audio speakers in my 98' crew cab chevy work truck, replacing the factory and adding 2 tweeters and 2 more in the rear doors. Powered it up with a good amp on a pioneer HU. It sounded great, but it was missing something. In comes the NVX QBUS8, "The little sub that could". I mounted it to the back wall of the truck and cranked her up. man this thing hits, even got a little flex out of the back panel. but mostly it filled the void my system was missing. Its the perfect little sub if you need some bass and dont have the room for a box and your not looking to compete. I may even look into getting a second one :)

Fantastic addition!

February 24, 2014

I replaced the "premium" 10 speaker system in my '95 911 with a new Blaupukt head unit, new 5 1/4" component MB Quart Reference fronts (purchased here) and added the NVX QBUS8 to fill in the bass. I kept the OEM Nokia 2-way rears and now this system rocks! I can't believe this little 8" sub can produce such powerful bass! Great product, I highly recommend it!

Impressive punch from a 8 inch sub

January 10, 2014

I purchased this hoping to add some bottom end to my sound while driving my motorhome. First I mounted it on the wall beside the passenger seat. Everything vibrated and sounded bad. So I placed on the floor next the passenger seat and it sounded better so I screwed it down, and that really made a difference. I have a 8" inch powered sub from Sound Ordinance and this one sounds much better. Would highly recommend.

2011 Toyota Tacoma TRD Sport Double Cab

December 11, 2013

The quality of this sub looks great. Installation and setup is no different than any other amplifier except it includes a built in sub woofer. The remote level control is a nice added feature allowing you to adjust bass level for the type of music you are listening to on-the-fly. I haven't actually installed this yet as it will NOT fit under the seats of a 2011 Tacoma without..... A. removing a bar on the bottom of the passenger's seat. OR B. covering the heater vents under either seat. Also, if you have a Weathertech floor mat in your backseat (like I do) you'll most likely have to notch it out to fit around the enclosure (kinda defeats the purpose of the mat).

Decent add on

November 2, 2013

This is a good sub for someone that wants to add some base to their stock speakers but not blow the roof off the car. It includes an amp built in so you don't have to get one separately. It provides good base but don't expect it shake the doors off.

On my second one

September 21, 2013

The first one only lasted 6 months. Sonic replaced it but it cost me shipping both ways, around 20 bucks. I"m 55 years old so I don"t think it was from using at max output all the time, it had to due with the mother board failure. I was hoping sonic would give me credit but they didn't. other then that sonic service was very good and they made me whole again. **** Update from Sonic Electronix: We have reached out to this customer and issued credit to make up for the inconvenience he had. ****

NVX QBUS8 car subwoofer

September 19, 2013

For those who need a solid easy to install bass but not necessarily "Ground shaking" bass then this is the best I have heard. For people inside the car this should be more than enough bass to move them unless you want people outside the car vibrating also.
