content: Why didnt you connect up a speaker to the amp so we could hear the sound quality and have you still got that projector

content: I have yet to see one video(/audio) recording of a speaker which gives a good representation of the quality of the speaker. It just doesn't work that that way. In every case, the speaker is going to sound like shit, even the best ones. What do you expect to learn?

content: How do you expect to discernscamspeaker(signal)by listening to(yourspeaker . yourdac . audiocodec . davesadc . davesmike . scamspeaker)(signal)? I'd imagine you'll only get anything meaningful out of that if the scam speaker is so bad it literally sounds like farts.

content: I have some very good quality Samsung speakers at home and no sound quality is lost by any electronic bits between them and the mic so it entirely fasts on the quality of the scam speaker and the air between the external speaker and the mic, if you had the equipment to do so you could plug the scam speakers output into the recording device to get a direct feed of sound quality, a bit like what cool dude Clem does+

content: Quote from: David_AVD on November 16, 2014, 08:03:29 pmThat's my point. The fact is, the recording capability of a camcorder, even one with a good external mic, is hardly going to be good enough to be able to record a sound system and let the person watching and listening to the recording have enough information to make an informed decision on the quality of the recorded speaker. I think Dave understood this and that's why he didn't bother wasting his time recording the output of that speaker.

content: Quote from: JoeN on November 16, 2014, 10:35:22 pmHe's quite right actually. It's classed as theft. You can be arrested for taking something out of a bin or skip.Also the same rule applies to a civic amenity refuse site. If you take anything you can be prosecuted for theft.As soon as anything touches a skip or designated area it becomes the council's property.However I often have a nose at the electrical section and have taken items though usually if I see someone going to dump something electronic I just take it off their hands.Stupid law really, seeing as the council/government are pushing recycling.

content: Quote from: TheBay on November 16, 2014, 10:39:11 pmThat's incredible. For all I know, maybe in some state somewhere in the US (laws can vary quite a bit by state) it's technically theft too, but I have never heard of such a thing prosecuted and it's pretty common for people to look through bins in cities. I assume it's quite legal in Australia since Dave is actually videoing it. What an ugly law to have in what is otherwise a nice society.

content: Quote from: JoeN on November 16, 2014, 10:42:02 pmYes its stupid. Think the same rule applies in England as well as Wales.I don't think anyone wants you to get something for nothing in this country.Lots of perfect food stuffs go to waste and you can't touch that either.When I was an engineer at the LG Factory we ran the old CRT based imac up on one production line, if we went over quota or Apple released a new model any spare had to be destroyed. We had a big hydraulic crushing machine. Most of us played 10 pin bowling with imacs and then crushed them. We begged to take them home or give them to charity but they said no.Such a wasteful society. I love finding something that's been chucked out and then fixing it. I've gone to dump my own crap down the refuse site and come back with more LOL.

content: Quote from: Refrigerator on November 17, 2014, 08:37:09 pmWhen I was young my dad acquired some very large Russian loudspeakers. I have no idea what make they were but they were old, large and sounded amazing.He also came home from an auction with about 8 pieces of an ITT HiFi 80 system which was bought for very little.That sounded absolutely amazing. It got passed down to me and I gave it away. I wish I hadn't now as I recently found out it was part of their Golden Ear range and very expensive. Each unit was their top tier model.

content: Quote from: TheBay on November 17, 2014, 08:40:09 pmMust've been Radiotehnika speakers ( late 1970s mid 90s ), yet there were alot of big speakers from them If they were very big they probably were the Radiotehnika S-90 if they were big ( a little smaller than S-90 ) and super heavy they were Radiotehnika S-70 ( built in amp inside thus the weight ).You can google for images and see, note that there are three different models of the S-90.

content: Quote from: Refrigerator on November 17, 2014, 08:55:07 pmI had a look and these were a fair bit older. Would say 60's - 70's, the grills were non removable. Very wide. Big woofer. 3 way if I remember correctly, the mid range had a plastic back on them like a disk that was sort of marble looking reminded me of half a bowling ball.I sold them to a friend who used them for discos!

content: Quote from: Arlen moulton on November 15, 2014, 05:41:08 pm"very good quality Samsung speakers" - Samsung are NOT a high quality speaker manufacturer, if this is the best you have heard you are missing out on more then you know."no sound quality is lost by any electronic bits" - So you have an infiniate resolution ADC & DAC on your soundcard, op-amps that are 100% noise free, resistors that are noise free, and using either uncompressed WAV or FLAC over a youtube video? I think not."plug the scam speakers output into the recording device to get a direct feed of sound quality" - Ummm, who here knows how to plug a speaker into their input? Perhaps you ment to say to record the amplifiers output? And if so, you will have to use some noisy resistors, or some other method to drop the signal level to record it on your completely lossless perfect low level input.

content: every one would need to have the same speakers, same amp, same EQ levels set to get some form of a bench mark and have an understanding of microphone used, ive sent my mate recordings of various things before done with a mic and he always tells me they sound crap laptop speakerswhich is ofcourse what hes using to listen to the audio with.but yeah just too hard, if you were gonna do it, youd want a spectrum spectrum analyzer and take a reading at set frequencies and various volume levels least you would have a visual interpretation, sadly those little amp ICs are hardly worth the time though.EDIT: and youd need a sound proof room
