SOLD AS EACH The 1000 watt rms subwoofer market is absolutely packed.  So what sets the Massive Audio KiloX apart from the rest?  The answer is simple, performance for your dollar.  The Massive Audio KiloX154 was meant to be the do-it-all subwoofer for your everyday musical install at a very reasonable price.  The features, specs, and quality make the KiloX154 an unbelievable steal for the money.  With the ability to play all the bass notes when called upon. The Massive Audio KiloX154 is the answer if you don’t want to break the bank on power as well as not limiting yourself to an entry level sub. We loaded the KiloX154 with many features from its bigger brothers to give it a huge advantage.   What are those features that make the KiloX154 such a good value? Well for starters, a 3”, 4-layer voice coil meant to withstand high temperature abuse. In addition, to fight that heat, we used an advanced T-yoke design that has rear venting to keep air flowing through the motor and the heat under control.  Not to mention, we kept the competitor in mind with large gauge direct leads.  Rated conservatively for at 1000 watts but capable of more in the proper design of an enclosure. We mated an oversized, high strength, double stack 180oz motor teamed up with dual poly cotton spiders to control that voice coil.  On the face of things, the KiloX154 has a Kevlar Fiber reinforced, non-pressed paper cone, which provides a natural tone and great cone rigidity for clean bass notes.  Addressing rigidity between the moving cone and the motor itself, is a strong, but lightweight, cast basket. For those who care about the show as well as the go, a KiloX line standard, there is red stitching to increase cone-to-surround connection strength.  The cast aluminum basket has a great textured finish, and the front and center dust cap is a fiberglass woven showpiece that can take a hammering.  To make wiring up easy and power flow to the coil, we have heavy gauge direct leads pre-installed.

SOLD AS EACH At Massive Audio, we aim to make unique designs to solve different challenges in audio.  For example, we approached the 10” & 12” shallow mount subwoofer market with the very cool UFO series.  But what if you needed even more extreme space savings with a smaller sub, while still having great bass in your ride?  Our all new Massive Audio SUMMO64S is an innovative approach to that solution. What makes the SUMMO64S special, yet unique in design you ask?  Well it's all in that new motor and new basket.  The SUMMO64S is taking the approach of reducing the height of the motor by reducing the height of the magnets.  But don’t worry, we make up for it by increasing the outer diameter.  That way no motor strength is lost, yet mounting depth is improved.  We also moved the SUMMO64S to a solid pole motor design to increase motor strength even more by adding steel inside the motor.  Your first thought might be, wait, doesn’t that affect the cooling?  Sure it does, that is why we went with a new basket design that employs loads of side vents for air flow out of the motor to keep the voice coil nice and cool under intense bass notes.  A benefit of the solid pole with no rear motor vent means you can go super shallow with the SUMMO64S as it does not need airspace behind the motor to stay cool. Now, you might notice there is a hex head screw in the back of the motor.  No, that is not to take the SUMMO64S apart.  That hex head screw is to take the efficiency of the SUMMO64S up another notch.  When a subwoofer is playing deep notes, often baffles can flex and that causes output loss if there is enclosure flexing.  You want all of the output coming from the cone and port, not lost or wasted in the box flexing.  All of this means, you can physically mount the SUMMO64S not only to the front baffle of the enclosure, but also to the rear of the enclosure.  You can do this by running that hex head screw through the back of the enclosure, into the back of the subwoofer moto

SOLD AS A PAIR 2 x SUMMO64XL Subwoofers! Tight space shouldn’t mean you need to sacrifice power handling and bass.  Our SUMMOXL line is all about premium bass output, with balanced response.  We want you to get a lot of performance from the low notes in your music.  Just because you do not have loads of space for a huge cone subwoofer, does not mean you have to settle for weak bass performance.  The SUMMO64XL addresses that head on. At Massive Audio, we aim to make unique designs to solve different challenges in audio.  For example, we approached the 10” & 12” shallow mount subwoofer market with the very cool UFO series.  But what if you needed even more extreme space savings with a smaller sub, while still having great bass in your ride?  Our all new Massive Audio SUMMO64XL is a hefty approach to that solution. The SUMMO64XL shares vital performance parts from the bigger models in the SUMMOXL line, such as the Kevlar Fiber enhanced non-pressed paper cone and OFC direct leads.  In addition, a 4-layer, high temperature voice coil, fiberglass woven dust cap, a high roll surround, and triple black poly cotton spiders with a mirror image layout.  All of the DNA from the SUMMOXL line, mixed with the innovative motor design, adds up to a very strong approach to a compact subwoofer that can keep up with the big boys. Our Massive Audio SUMMO64XL is a high-performance car subwoofer that delivers powerful and punchy bass. With its dual 4-ohm voice coils, the SUMMO64XL allows for flexible wiring options and compatibility with a wide range of amplifier setups. With its oversized 110 oz. ferrite magnet and high-temperature aluminum voice coil ensure reliable performance, even under demanding conditions. The specially designed non-press paper cone and reinforced steel basket provide a strong and responsive foundation for the subwoofer's impressive sound quality. Whether you're a basshead or simply looking to add some depth to your car audio system, the Massive Audio SUMMO64XL

SOLD AS EACH In the space of shallow mount subwoofers, only a few are capable of actually producing quality, deep bass.  The Massive Audio UFO10V2 is a stellar shallow mount option on the market today.  That is quite a statement, so let’s break it down as to why.  Shallow mount subs are here to solve the problem of limited mounting depth or space for a subwoofer.  Our UFO10V2 is designed to perform very similarly to a standard 10” subwoofer, but with half the mounting depth requirement, and that is exactly what we were able to do.   Now, how did we do it?  First, we moved to a flat cone for the UFO10V2.  The flat cone style gains some depth behind the cone, inside the basket itself.  Next we upgraded the strength of the magnets to a high flux Y30 strontium magnet.  That allowed us to reduce the width of the motor, therefore we were able to invert the smaller motor into the area inside the basket that is no longer taken up by a deep cone.  All of that work produced a mounting depth reduction down to only 3.1” total.  This all means, you can fit a great sub in that tight space now, you can still get great bass out of it too. The UFO10V2 is a must have for under the rear seat, or behind seat  boxes for pickup trucks.  To produce the same great bass that the renowned TKO series does, we used a very similar 2.5” EISV aluminum voice coil, and gave it loads of venting, through the basket and through the pole, to keep cool under hard bass notes.  We also brought over similar cotton progressive spiders with woven leads to keep the cone under control and no mechanical noise.    With an rms power handling of 300 watts and 8mm of Xmax, the Massive Audio UFO10V2 really sets itself at the top of the shallow mount subwoofer market.  We do our best to develop a great subwoofer for all types of needs and budgets.  The UFO10V2 is not just a great performer in a small space, it is also a killer value too.  You will be hard pressed to find a quality comparable sub in this price bracket
