Delivering Powerful and Clean Sound Like a BOSS!
The media could not be loaded. I purchased two BOSS BRS40 4", 4-ohm, 50-watt speakers for a cigar box speaker-amplifier project. I paired these speakers with a class-d amplifier capable of 30-watts peak/15-watts x 2 RMS. To ensure I had some punch in the bass of these full range speakers, I made a small port in my cigar box speaker-amp. I was surprised in the ample bass response coming from these speakers nestled in a 3.75 in. deep cigar box. The speakers arrived on time and in good condition. I would definitely recommend these speakers to family, friends, coworkers, and acquaintances. I think the price was good and the speaker performance is even better. I am going to purchase these again for similar size cigar box projects. Matter of fact I have two very nice Drew Estates Tabak Especial (Coffee Infused) cigar boxes sitting in my office that will be well suited for this speaker. Unfortunately, I have six other cigar box amps in line before them.

el cheapo
these are the cheapest speakers money can buy so far had them for a month and they sound 10000x better then my 20yo speakers that came with my festiva. If your looking for a replacement speaker for your beater upper and money is a problem get these they are not that loud and wouldnt recommend going too loud on these since they are dirt cheap. If your looking for a replacement for your 4inch speakers and you only got 20bucks then you wont be dissapointed. you can get 5 speakers for 25 bucks wayy cheaper then walmart.Pros-cheap, sounds pretty good, decent quality, looks good, cheap cheap cheap!!!Cons-might blow if you turn it too high, not for high end systems might blow once again,

Great for the price for Toyota Door Speakers
I used these in the front of my 2002 Toyota Avalon. I had to do some minor modifications to get them in the door boxes, but they fit well. I felt they were a little lacking on the base frequencies, but sound good considering the low price tag.

Great replacement
Have an old under cabinet radio that needed a new. Speaker it matched what I needed for it. Some slight modification to modernize it for a better newer speaker. It works well sounds good for me when listening to my music. Just so long as you're not expecting super bass or anything it actually has a good sound for a smaller speaker. And for the price it does the job I needed it to do.
