Enjoy audio from your favorite sources with this pair of hi-gloss white Audioengine A5+ 2-Way Bookshelf Speakers. They output up to 100W of total RMS power and are equipped with a 5" aramid-fiber glass composite woofer and a 0.75" silk dome tweeter to provide full-range audio. A USB port lets you power an optional wireless module or charge your smartphone or tablet during playback. The speakers can be mounted via 1/4"-20 threaded inserts on their bottom panels.

To minimize unwanted resonances and distortion, Audioengine cabinets have 0.5" thick high-resin MDF walls with extensive internal bracing. Heavy internal sound-damping material is used to reduce unwanted sound reflections inside the cabinet. All cabinet edges are rounded which look great and reduce high-frequency diffraction effects on the front baffles.

The A5+ cabinets are available in several handsome finishes, offering a wide choice for complementing room furnishings.

Audioengine designs and manufactures their own tweeters, woofers, and other critical components. In other words, these are not "box built" speakers with off-the-shelf parts, but custom-designed to their specifications. What they do not fabricate directly in their factory is made to their designs (parts such as transformers, magnets, and wiring harnesses, for example). The cabinets, drivers, bass port designs, amplifiers, and crossovers are all painstakingly tuned together for each Audioengine model. This, in turn, makes for a much more efficient system that requires much less power than passive speakers and a separate integrated amplifier or similar A/V components.

Studio monitor speakers are used by producers and engineers in recording and production studios. They are designed with a theoretical flat frequency response, which allows the engineer to create a final mix in such a way that the recorded music will sound good on most other speakers. Although Audioengine speakers are not designed to be up-close, or "nearfield" studio monitors, they carry over much of the same higher-end technology, components, and design philosophy for all Audioengine speaker systems.

The speaker cabinets, drivers, innovative bass port designs, amplifiers, and passive crossovers are all critically tuned together for each Audioengine model. This, in turn, makes for a much more efficient system that requires less power than passive speakers and a separate integrated amplifier or similar A/V components. They build all this goodness into the left speaker cabinet to make it super-easy to connect your smartphone, tablet, computer, TV, network player, or any other audio product.

The Audioengine A5+ includes a 5V, 500mA USB power supply for charging portable devices while listening to your music. The USB connector allows you to charge and power your smartphone, tablet, Audioengine wireless adapters, or any other USB powered product. USB is for power only, not USB audio or data transfer.

The amplifiers in powered Audioengine speakers are located in the left speaker and are a conservatively rated class A/B analog monoblock design. This is a more traditional speaker/amplifier marriage which provides excellent quality audio and greater flexibility. All circuit boards for the power and preamp sections are vertically mounted for maximum mechanical shock protection.

Audioengine uses audiophile-quality, ferrofluid-cooled silk dome tweeters with neodymium magnets. Silk tweeters hold up well under high power, and the edge-driven design gives very smooth response. The woofers are aramid fiber woven glass composite with rubber surrounds. Aramid fiber is obviously very strong, which means that the woofer retains its shape when being driven at high levels. The speaker materials and construction are robust enough to stand up to some serious thrashing, so speaker grilles are not needed and they will sound and look great after many years of use.

Both drivers are directly video shielded and allow you to place the speakers within a few inches of a video monitor. This shielding also offers protection for hard-drive digital music players.

Power transformers are a large contributor to the overall audio performance, especially in the low end. Again, no off-the-shelf parts. Audioengine uses gapless core toroidal transformers which have a tighter radiated magnetic field, directly translating to lower noise. They are lighter than standard, lower-cost transformers and also generate less heat.

Related Questions and Answers

Q: 1. Would this head work on the Manfrotto Befree tripod?

A: As long as the tripod has a flat top with a 1/4 screw it will work but this is a pan/tilt head, larger and heavier than a regular ball head.

Q: 2. Will this head fit on 3021 Manfrotto legs?

A: As long as the tripod has a flat top with a 1/4 screw this head will fit.

Q: 3. re: answer to counterbalance springs in Manfrotto 808RC4 - question was not answered. How do I "simply turn the springs off" and on?

A: On the 808RC4, there is a little knob beneath the quick release clamp (you can see it in the second picture) that you simply have to turn.

Q: 4. Does the 808RC4 have retractable handles like the X-Pro 3-way? That feature would make it much easier to fit in a tripod bag.

A: No, the handles do not retract...but they can be removed (unscrewed out).

Q: 5. What is the diameter of the legs?

A: The leg tube diameter of the Manfrotto MT055XPRO3 Aluminum Tripod is 30mm, 26mm, and 22.5mm.

Q: 6. What country is this made in?

A: The Manfrotto MHXPRO 2-Way, Pan-and-Tilt Head with 200PL-14 Quick Release is made in Italy.

Q: 7. Hi Experts, I'm a novice and basically trying to buy this head in order to record subjects in motion (flying birds, boots etc) for short length movies. Does this have the speed capability? For a Canon PowerShot SX60 HS.

A: It shouldn't be slower than any other head. However shooting single birds in flight is very difficult. Shooting flocks from a distance will be much easier. Most still photographers handhold their rigs (DSLR+Telephoto) to shoot birds in flight.

Q: 8. Hello,I am new to tripods and I was advised to buy the Manfrotto 055CXPRO4 Carbon Fiber Tripod along with this particular head. Is that a good/compatible combination?I was also advised to buy additional quick release plates. I will need one each for a Canon EOS 1DX, a Canon 7D and the Canon EF 100-400mm f/4.5-5.6L IS USM Lens. Please could you give me the information on the appropriate/compatible quick release plates? Thank you.

A: Yes. The 055CXPRO4 tripod would work well in combination with the 808RC4 head.For additional plates, I would recommend getting these:Manfrotto 410PL Quick Release Plate - for RC4 Quick Release SystemB&H # MA410PL ? Mfr # 410PLThese will work underneath your two cameras, as well us under the foot of your 100-400mm.

Q: 9. Would I be able to use a medium to large size gimbal head on this tripod?

A: The Manfrotto MT055XPRO3 Aluminum Tripod has a maximum support weight of 19.8 lb. Technically, as long as the total weight you are putting on the tripod including the head, camera body and lens is no more than around 19 lbs it should be fine.

Q: 10. Will this tripod be a good combination with the Manfrotto MVH500AH Fluid Video Head?

A: I don't use Video heads, however I believe this tripod would work well with any combination.It has all the fundamental makings of a very good tripod and then someGood luck and Aloha.....
