12 Inch 1800W 50 Core High Power Car Woofer Car Speaker
US$92.99 US$117.99

Q: Do you have any real specifications for this driver, or are you going to quote the totally fictitious 1800W (PMPO?) figure again? This would require rails of +/- 120V and peak current of 30A!

Q: What are it's specifications, such as accuracy and ranges.
And what's the stuff about bluetooth speaker - or has a non-English speaker copied and pasted something from another product?

S032HIFI 150W+150W High-power Dual Channel Amplifier Finished Board Equipped with ON Transistor
US$48.08 US$52.31

Q: Do you have any real specifications for this - I severely doubt it has 150W capacity into both 4 and 8 ohms, and it certainly couldn't do that with a 100W transformer?

Asked by Quokka42 on 2022-08-17 05:45:10

liangyan6 150W+150W is right.

US$74.99 US$67.99

Q: Good night. Frequency is 700mhz? The ad title says 700mhz, but the product description says it's 900mhz. I need it to be 700mhz.

Asked by Cid Dias on 2022-02-12 11:39:56

Quokka42 It also says the unit is 200m long and only covers 200m2 (which is about 14x14m...) I would take all of the specs with a grain of salt.

Quokka42 Hi.Can you clarify if the input is 18V CT or 18 18V

This is a very good product. The LM1875 amplifiers are well known and produce good sound. The power supply capacitors provided in the kit a Nichicon good quality and resistors are metal film. Even the lesser components from unknown brands are of good quality. The heatsink is well calculated and the kit comes complete except for the AC transformer. Worked the first time. The tubes are connected as grounded cathodes and thus actually amplify the sound. The tubes supplied, a 6N1 Chinese pentode, were used and one of them totally worn out, but still worked even at low voltages. I upgraded all caps and resistors in the signal path and replaced the tubes with 6AK5 units. With a small change in the filament supply replacing the limiting resistor by a current source, which by the way eliminates the background hum, one can use several different pentodes like the more common 6AU6. Result is above expectations, Highly recommended.

Q: can please Somone tell me how it can deliver 800w with 15 volt single feeding 🤔

Asked by BG413254442 on 2021-06-18 12:09:31

Quokka42 It can't, it is obviously a "PMPO" type rating. Going by it's claimed output voltage it should deliver 36W into 4 Ohms.

As others have mentioned, this is not a bad product at a fairly reasonable price, ruined only by the way it is sent folded in a soft packaging, causing cosmetic blemishes (which would also be structural if you were using it seriously, but then you would probably pay slightly more and get the real thing locally, right?)

Works well. If you are using it with SKR1.3 you need to grab one of the spare jumpers you have laying about and pop it over the two upwards pointing pins to tie send and receive together. You could use one of the supplied leads, but this way looks neater.

This is not an IP camera and I cannot get it to work on WiFi. It does not register itself on the WiFi and if I connect to it via LAN it disables the WiFi, plus as it is not really an IP camera I still have to use the included app, which won't do most of the things you expect of an IP camera. Basically it is a nice looking Nanny-cam, with the limitation that you have to use a wired connection.

This was my second one, but not due to quality issues (although I threw out the probes that came with the first one the day I got it.) My tools were stolen and this is one of the items I couldn't live without. My Fluke stays safely at home, and doesn't even have a lot of the features this one does. Most important to me are the temp, capacitance, non contact voltage detection and continuity, but this one really does do just about everything, and surprisingly well.

Love Love Love the SKR 1.3!!! It has a few quirks, just do some searches or join the BigTreeTech Facebook page. I find it easiest to load the firmware onto the TF card using a card reader (the printer works without it, it is only used for loading firmware and keeping a backup copy,) and be aware that you cannot print from SD card if you still do that - unless you have another slot on your display. Now that Marlin 2.0 has a solid release it kicks!

Another Mustool tool I replaced only because it was stolen. Works well, can even be useful for fault-finding as it can detect lower voltages or even Neutral lines. Sometimes the little built-in torch can be a lifesaver. There are a lot of similar products out there, but this one tends to work, and work well. I use it more than my much more expensive "Brand-Name" voltstick!
