Review on MakerHawk 2pcs Arduino Speaker 3W 8Ω Single Cavity Mini Speaker Full-Range Cavity Advertising Machine Speaker with Connector Separating Interface 3.3V 5V and JST-PH2.0mm-2 Pin Interface by Rusty Heredia

These 3W MakerHawk 8 ohm speakers are designed for 3.3V and 5V Arduino projects, but I can confirm that they work as general purpose speakers for audio projects. I'm hoping to pick a few to add to my OQO model 02 umpc. I chose 8 ohm speakers because they require less power and also because my umpc's built in sound card is designed to drive a single wafer thin piezo speaker. I have created a playlist using the Winamp audio player program on my Windows XP Pro SP3 OQO model02 umpc with electronic genre music that has a wide range of high and low frequencies. I cranked the volume all the way up and didn't turn on the OQO Model 02's built-in quarter-inch piezo speaker, which sits on top of the fan's plastic casing, which only plays higher frequencies and very often cuts out at volume levels between 60% and 100% is increased. . During testing, I momentarily touched the wires of all three speakers in turn. The smallest speaker has an oval shape and a transparent Mylar cone. It's about 10% louder and improves bass response from (none) to the amount of bass produced by a smartphone speaker. Smallest speaker (not suitable) for my project. The medium-sized loudspeaker has a black, twisted fabric membrane. It's about 30% louder and the bass response has been improved from (none) to netbook speaker bass response. I attribute the improved bass response to the boxed body and vent. I noticed a lot of high-frequency clipping from this speaker, which looks like a built-in piezo speaker. A medium-sized loudspeaker is not suitable for my project. The large MakerHawk driver has a textured metal cone and is surrounded by black foam. As I touched the wires of the large MakerHawk speaker, I was amazed at how much volume and bass such a small speaker produced. Overall volume has been increased by 400% and bass response has been boosted from non-existent to the low-frequency response of a small keychain Bluetooth speaker. I am planning to permanently attach two of these speakers to both cases of my OQO umpc. It will now have two front speakers that combine to produce multiples of volume with the desired deep bass. The housing in a plastic box is very durable and boosts low frequencies. There is no breathing hole on the cardboard case that I could add with a 1/8" drill bit. The wires are nice and thick, which is always a plus for sound transmission. Two built-in brackets with screw holes ensure secure attachment, although I only need one of them. They also look gorgeous with their shiny textured metal cones. I've always liked the look of metal cones compared to clear mylar, black paper, or woven fabric cones. You will love adding them to your mods and projects.
