Great speaker for the price!
For the price, this really is a great little speaker. I run patio speakers in the back of my Jeep so I can open the tailgate and flip them out to play tunes when I am camping/working on my “up north” property. The all-weather design leaves me with no concerns if it rains. If I am staying up there for more than a couple of days, I even hang them in the trees and run speaker wire back to the Jeep. I purchased these as a downgrade from my Klipsch KHO-7 pair, simply because they were too big and got in the way when I am loaded down with gear.They sound pretty good. The highs are clear and crisp without being too bright. The mids were a tad strong and “squawky” at first, but I was able to correct with an EQ adjustment. Bass lines are strong, but don’t expect to be blown out of you seat with a 4.5″ woofer. I can’t speak of deep bass, as my sub woofer takes over at 120Hz. The sub is another reason for the downgrade from the Klipsch’s – there really wasn’t much need for a large enclosure when the sub takes all the big hits. They are being driven by a 250w amp, which is probably realistically a 150w amp that I only use 100w of at peak. They take the power fine, but do of course have a limit before they distort if I really try and push them That limit is beyond my useful range anyway. They are loud enough that they become uncomfortable after a few song up close, and project enough that I can hear the tunes clearly on the front 5 acres of my property. Overall, and considering the price, they are a surprisingly comparable to the Klipsch’s in sound quality. While they do project well on my wooded lot, I have to give that win to the Klipsch’s and their horn-loaded tweeter. In closing, these were well worth the $50. With the abuse these see in the way of being bounced around in the Jeep, I expect to get 2-3 years out of them. If they fall short of that, I will update here as long as Amazon will let me….

Work well in a portable backyard theater setup.
I purchased 3 sets of these of these speakers to set up a 5.1 channel portable backyard theater sound system. For my use they are perfectly adequate and at the price offered, allowed me to set up 5.1 channel system rather than a more traditional 2.1 system. I have the speakers mounted on home built stands based on 2x2x36″ metal fence posts mounted to 8x8x2″ paver bricks, which allows for a good balance of stability vs portability/easy storage. The speakers are connected to a Sony STR-DH740 receiver with 14 GA low voltage outdoor wire and inexpensive banana plugs. The low end is supplemented with a BIC PL-200 subwoofer.Given the low price of these speakers, I am satisfied. The sound is more than adequate for my intended purpose and they can reach higher than comfortable listening volume without objectionable distortion. The spring loaded wire connectors are cheaper than average and require some finesse to hold the admittedly larger than recommended 14 GA wire. If the speaker is moved relative to the wire, it is likely that they would become disconnected. In an attempt to possibly change the wire connectors to something better, I disassembled one of the speakers only to find that the existing terminal is soldered on and epoxied into place. Changing it out would require cutting the internal driver leads and modification to the speaker housing. For the time being I’ll leave them as they are and see how the current connections hold up.Internally, the speakers leave a bit to be desired. There is no crossover to speak of. One capacitor is used as a rudimentary crossover between the tweeter and 2 1/2″ driver, while the 4″ driver is simply wired in parallel with the other 2 drivers. This wiring likely contributes to the relatively high impedance of these speakers. Driver quality is about what one would expect from speakers at this price point. I was surprised and pleased to see a bit of fiber fill in the speaker housing.As I store these speakers out of the elements when not in use, I can’t comment on how well they handle the weather, but they do seem relatively well sealed against the elements.For regular, daily usage, I would probably step up to the Yamaha’s at roughly twice the price. For my occasional usage, however, they are more than adequate.

Amplifier – Archeer G30Speakers – Dual Electronics LU43PBI pushed in or removed rear connectors on both devices , antenna too , I soldered all the wiring.—Speakers are well made (5/5) and disassembly was easy, pop the mesh and unscrew six screws.Speaker swivel brackets was perfect fit to hold amplifier.—Too many disinformation about the amplifier:-Size: 8.27”x6.3”x2.75” is not correct.Size without front and back knobs , connectors is 190mm x 125mm x 45mm ( 7.48” x 4.92” x 1.77”).-24V input, will not work.-Built in power supply is inadequate, with my two speakers, 4-6 Ohms, playing from TF card, with maximum volume it will not work more than 4 minutes and then it starts restarting. Any volume on the knob above approximately 45% it will end up eventually restarting.Amplifier was easy to disassemble. It has two separate PCB boards, front controls and rear connections.Caution:Rear connections PCB board is also 110V input and it has no insulator underneath it (I put a sheet of plastic and secured it).This is pretty much like a lottery but, lets say you drop the amplifier it hits something sharp and the bottom aluminum casing of it bends inside and it touches 110V live wire on PCB, not making a short, now your entire amplifier aluminum casing is conducting 110V…USB/TF, after shutting it down and turning it back on it starts playing last played file from the beginning.I tried MP3 , FLAC.Manual:-”MODE” you are cycling trough all the inputs (TF,FM…).-”VOL-”,”VOL+” short press = previous, next file or station.Long press = changes volume.-”SCAN” short press = pause, play or mute, unmute.Long press = Scan, stores available FM stations.—Sound is clear and reasonably loud at ~45%.

I got these tiny speakers for a silly price, as a refurbished product (not that you’d know). But even at the regular price you’re getting a bargain as they possess a clear, strong and very rich sound for something that is largely plastic. Don’t expect a deep bass at this tiny size and price, and you won’t be disappointed. But do expect a very decent sound and a very solidly made item.

Product came earlier then expected and is in excellent packaging. Have not use it yet but items looks well made.
