    • Sound quality
Size: 4 Ohm
They are impressive for small speakers, I installed them on my motorcycle. Sound is incredible. Even at full power with a 200 watt amp..I would definitely recommend them no distortion.

    • Great Sound - Great Price
Size: 4 Ohm
These speakers sound great for the price. Much better than other speakers I’ve purchase that are at least double this price.

    • Quality and value, I would buy again
Size: 4 Ohm
Decent size magnet to handle the power, rubber surround and paper cone material. Terminals are basic. I’m Saying these really preform well. Test bench tested them using a 100 watt amplifier and they sounded great. I ran them both full range and also using a band pass crossover (800-4000hz). I ordered the 4 ohm version and I used a band-pass crossover filter to integrate these in my car’s front doors to build a nice three way set up. The result really cleared up the midrange frequencies and these can take plenty of power especially using a quality crossover. They are also very efficient so they play nice and loud. The midrange clarity of these really brings out the clarity in vocals and acoustic instruments. I was surprised they can put out some decent bass for their size too so you may want to run these full range to get a lower end response. I’m not sure what the upper frequency roll-off is but on the low end the seem to do pretty good down to 200hz I did not look at an spectrum analyzer so I’m saying this based on my listening and experience. For the price you won’t be disappointed though I do feel these will sound best within a two or three way system. ... show more

    • Good quality speaker with good sound.
Size: 4 Ohm
Nice speaker well made sounds good. Bought this to make a novelty portable Bluetooth type speaker but was very impressed with it. Will have to get another set in the future to put in a proper box.

    • Strange cone resonance and lacking bass.
Size: 4 Ohm
I was using these and could never seem to adjust my EQ to make them sound right, I ended up replacing them with a different 3” full-range driver by DA and they sound significantly better.

    • Smooth sound.
Size: 4 Ohm
Decided to give these a try, although i was leaning towards paper cone to avoid tinny sound beside super tweeter. Well, this is way mellow like silk dome. Must be the rubber surround. Stout little bugger, too.

I used these for a Bluetooth speaker project for my shop based on my experience with some other speakers by the same company that are no longer available. These did not disappoint. The highs are surprisingly crisp and clear. The bass is better than expected for a 3” full ranger. The box is ported and tuned to 60 Htz and the speaker sounds much larger than it is. ... show more
