The A5+ Wireless Speakers are Bluetooth speakers with sound that fills any room and connects to any device. No network setup, passwords to enter, or buttons to push.

ลำโพง Audioengine A5+ Wireless Speaker ราคา อยู่ในระดับกลาง แต่ก็มั่นใจได้เลยว่าคุ้มค่าอย่างแน่นอนเพราะด้วยแบรนด์ Audioengine จากหลายๆ รุ่นที่ผ่านมามั่นใจได้เลยว่าเสียงดีอย่างแน่นอน และในรุ่นนี้ก็มาแบบพรีเมียมเช่นกัน ไม่ว่าจะเป็นขนาดที่เล็กแต่ให้เสียงได้ดังกระหึ่มเลยทีเดียว มาพร้อมการเชื่อมต่อไร้สาย Bluetooth รุ่นใหม่ล่าสุด โดยที่ยังคงการเชื่อมต่อแบบมีสายเอาไว้อย่างครบถ้วนด้วยเช่นกัน

Audioengine designs and manufactures our 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 our specifications. What we do not fabricate directly in our factory we have made to our 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.

DRIVERS

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 grills are not needed and they will sound and look great after many years of use.

POWER AMPLIFIERS

The amplifiers in Audioengine speakers are located in the left speaker and are a conservatively rated analog design. All components are tuned together for each model, which provides a much more efficient system requiring less power than passive speakers and separate amplifiers. Circuit boards for the power and preamp sections are mounted for maximum mechanical shock protection.

POWER TRANSFORMERS

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.

SHEILDING

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