Hifonics B15D2 Review

The Hifonics B15D2 is an easy and an incredibly affordable solution for those of you who would like to experience a 15" subwoofer. It's both stylish and powerful and will be sure to turn heads when you play and bump your music in your ride.
Pros
The Hifonics Brutus Series B15D2 15" subwoofer features a large polypropylene cone with a woven honeycomb supporting structure construction. It allows for the subwoofer to be both consistent and durable at an above average level. Polypropylene is a great material to have, but to have it perform at its optimum level, it requires a little bit more reinforcement such as glass fiber or carbon fiber synthesized into the material. The B15D2 does feature a nice large stitched nitrile butadiene rubber surround that is one of the most durable yet elastic material available for subwoofer construction. The surround is also stitched instead of glued on or pressed on to the cone construction which also adds to the B15D2's ability to perform at high levels consistently.

The Hifonics subwoofer features 3" dual 2 ohms 4-layer aluminum voice coil with a unique Nomex spider tinsel lead that is a 1 piece design. Its giant motor structure has 6 sided venting that gives the subwoofer adequate ventilation and less space to worry about in the enclosure for venting. In addition, the Hifonics B15D2 houses a large double stacked 100oz. magnet that is capable of driving the subwoofer to producing excellent bass. Last but not least, the B15D2 Brutus subwoofer could handle 700 watts of continuous RMS power with a whopping 1400 watts maximum power handling.

The Hifonics B15D2, with all its features, power handling ability, and 88 dB SPL, is priced nicely at under $125.
Cons
The only thing that is glaring with any 15" subwoofer is its size. Though users will experience great bass output from the Hifonics B15D2 subwoofer, finding a place to mount it could be cumbersome. The Hifonics B15D2 requires anywhere from 2 - 3.25 cubic feet of space within an enclosure. In order to achieve this, the enclosure must be as long as 24" long and 17" deep. If you have a small vehicle, forget ever having either your bass or your cargo space ever again.

We also didn't like the cone material. To us, it seems like if you're going to make a 15" subwoofer, at least make it with something out of the ordinary. 15" subs are usually bought by audiophiles and not your typical loud-music loving high-schooler. A polypropylene cone woofer for a 15" subwoofer render it almost not worth the purchase. But if all you're looking for is deep bass with lots of volume, then the Hifonics B15D2 may be your best bet.

JVC Arsenal CS-AW7040 Revew

If you’re looking for performance, the JVC Arsenal Series CS-AW7040 can provide your deepest bass needs. This 10” subwoofer could put out 600 watts of continuous power with 1800 watts maximum power handling. This means incredible power handling and you could sure bet that the CS-AW7040 will outperform most other 10” subwoofers out there.

The monster subwoofer features a glass fiber hemp composite cone woofer. This cone material is the signature composition of the JVC Arsenal series subwoofer. It is designed to reproduce sound as naturally as possible. Their design philosophy includes the notion of natural material, such as hemp, capable of producing natural sound using its natural physical and chemical properties. But of course, not everything is natural on the CS-AW7040. Take for instance its surround material—it’s made of synthesized rubber called santoprene. It’s quite possibly the strongest surround material available in the car audio industry. It allows the cone to move up and down as much as it needs to produce high quality sound without it tearing from the structure.
The basket is made of aluminum die-cast construction which reduces the overall weight (though it’s still quite heavy). But the massive aluminum basket is capable of dispersing heat so that the subwoofer is still capable of functioning efficiently and safely. What’s amazing about the CS-AW7040 is its Rapid-Fire Impedance Selector Terminal, which is another uniquely Arsenal characteristic. It allows users to select impedance according to the output from the source.
The subwoofer also features dual 4 ohm voice coil, heat transfer silicon structure, and a large 65.4 ounces (approximately 4 pounds) of magnet. With all the incredible features, it’s surprising at how low you could get the CS-AW7040. Expect prices to be as high $300, but there are a few stores out there that have them for cheaper even as brand new.
The JVC CS-AW7040 is truly an amazing subwoofer. You’ll enjoy its dependability, performance, and monstrous deep bass. The only thing is its large size. It makes it rather difficult to mount in various sub boxes. I guess that’s the price to pay in order to have power bass output from the sub. The addition of this subwoofer to any car audio system will sure turn heads and put a big smile on your face. Just be weary of its enormous size. It’s probably bigger than most 10” subs out there. If you like deep bass, the JVC CS-AW7040 is the subwoofer for you.

Pioneer TS-W1007D4 Review

Finding an affordable yet high-performing subwoofer isn't an easy task, but the Pioneer TS-W1007D4 is exactly that. It's not everyday that anyone could get a cheap subwoofer that is also powerful and reliable; so read carefully because this may very well be one of the best deals available to you.

The subwoofer features the now commonly used injection molded polypropylene cone woofer. However, it is not just plain polypropylene but is compounded with interlaced aramid fiber or also known as Kevlar. The material utilized along with its woven fiber radial surround creates an extremely tough and rigid construction, allowing for greater bass response while maintaining consistent performance in any environment.

The Pioneer TS-W1007D4 is primarily regarded as an entry-level subwoofer. However, it packs a big punch for those who do not want to spend much money on their car audio equipment. Its 10" cone woofer is capable of delivering up to 1000 watts maximum power and could consistently produce 350 watts of CEA rated RMS power out of dual 2 ohm ( TS-W1007D2) or 4 ohm (TS-W1007D4) 4-layer copper voice coils. Don't overlook its hefty 74oz. dual-stacked magnet structure that when combined with the mentioned specs could produce that boomy bass you've always wanted.
Another great feature of the TS-W1007D4 is its ability to pick up frequencies as low as 18 Hz to as high as 600 Hz. This means that this 10" subwoofer could produce sound frequencies just below what you would typically call "midrange". When combined with a decent component speaker system, the results would be great audio reproduction in your vehicle.
Cosmetically, this subwoofer looks good. It has a classy look, not overbearing, but is still able to give off an intimidatingly powerful image. The basket is a stamped design with all four terminals on one side for easier installation. An additional but optional grille is available, allowing the cone to be protected and cosmetically enhanced.
