Dayton Audio DMA45-4 1-1/2" Dual Magnet Aluminum Cone Full-Range Driver 4 Ohm

This driver is small, but it produces surprisingly good sound for its size. I installed it in a custom enclosure that I designed and 3D printed myself, and it worked very well. The sound is clear and powerful enough for a small DIY speaker project. Overall, I’m very satisfied with the performance and would recommend it for custom speaker builds or 3D-printed audio projects.

The quality of this speaker was nothing short of impressive. Paired with a mathematically correct enclosure for its air displacement, it sounds spectacular. Very clear highs, punchy mids, and smooth subtle lows.

This little speaker is just fine for what it is. Put it in a stiff, sealed box and it will sound decent!

These are some nice quality speakers, great for custom builds, currently going in a custom built RC

This ia a terrible speaker. Do not like the quality. Not worth $14.

Awesome sound perfect for R.C. projects

I originally purchased to replace the speaker in my Echo Dot 3, but it’s too large. However, it did turn out to be perfect for arduino projects.

Worked perfectly for my rc application. Solid sound, very clear and quite good

同じサイズのスピーカーから見たら、低音、バランスが良い、聞き疲れしない！nfjで絶賛されてるピアレスよりもこっちの方が好きです！

Bought this speaker as an upgrade for a project I'm working on. I was using cheap ones off ebay and after going through 6 of them decided it was time for an upgrade. Found these and I can honestly say that these are superb. Sound is defined and produces a good volume considering its size. If your looking to boost you small driver set up or just need a replacement then these are the ones for you. Good base reproduction and nice clear highs.

Very good little speaker , the sound of the voices are crystal clear , and he can produce a small bass (not too heavy but remember it's a 1"1/2) . I put it in a 9cmx6cmx6cm (external) jewelry box (sealed) with a small 5w Bluetooth amplifier board , the sound is very nice and powerful
