Gearbox - fairly sure it's a noisy bearing. The original didn't do it and I could probably have used it as it was, but I had a rebuilt one lying around. I want to put the originals back in to keep the numbers matching, so no more work to try it anyway!
I have a pair of these 50 watt speakers in seperate cabs, they are quite big and very heavy, the wife cant understand why I dont take them to the tip, stupid woman. They are.from the 70's too and I had a sony trinitron that turned green, I now know whyIt can be confusing with many manufacturers not stating RMS [true music power]. 50 watts rms is blisteringly good from one speaker, as good as my old KEF kits with early flat diaphragm bases - hand made in September 1976 with extra-ordinary clarity. They generated so much emf they turned part of my old Sony Trinitron TV screen green...
Re the JBL, it's only 40 watts total [2x 20w sub-woofers] but does the job quite well
I agree that modern multi speaker cabinets are more efficient than the old single speakers and you can hear the sound with more clarity however, I have an amp that can push 75 watts rms out of each of its two channals. If I plug my 50 watt single speaker cabs into it I get more/louder sound than I do if I plug my 60 watt multi speaker cabs into it when the amp is at the same setting. The multi speaker cabs have got a.slightly better sound and they are a heck of a light lignter.Say you have a single full range driver (speaker) rated at 50 Watts, then it's reproducing the full audio spectrum, and will consume as much power as you feed it.
Then you have a multi-driver cabinet, with bass, mid, and tweeter, which is still rated at 50 Watts. The power here will go through a passive crossover, which splits the sound up, sending the power to which ever driver that can handle the relevant frequencies.
In this instance, the amount of power going to each driver will vary, but as higher frequencies are easier to reproduce, the smaller mid and tweeters take less power, with a vast majority of the 50W going to the bass driver.
As for loudness, that's more a function of the speaker driver's ability to reproduce the sound efficiently, coupled with it's power handling capacity.
I low efficiency, high power driver, may only be able to produce the same audio output amplitude, as a higher efficiency, lower power driver.
I'll just add that I decided to try my noise cancelling headphones on two trips in the last week. The first in the Fiat about 80 miles down to Lymington and back in the heat, windows open all the way, that was with music and way better than the fitted stereo (upgraded but still rubbish). The second was down to Hamble and back in the Lightweight. Talk about transformation! I didn't use music, just semi silence. I could hear all the traffic, sort of in the distance, but it got rid of the all the unpleasant noises and made the drive a real pleasure. No way bt speakers could compete.
Interesting this. don't know what would have happened if you'd got stopped.
Mmm. I said above, I was once 'sort of' stopped by the police just to satisfy their interest. I've also asked separately and they too didn't know of any law against. And again, as I said above, how about deaf drivers?
I see what you mean about (the new) French law, good grief, must be the cheese. Hearing aids allowed, so I'd argue that my Tinnitus benefits from noise cancelling. In fluent French, obviously.
All totally correct and fair!
I have (mild) tinnitus, I never do anything about it other than wishing I could hear "the Sound of Silence".
Mine's very mild, but I'm fairly convinced that I triggered it by doing a lot of hammering in a concrete building - the ringing in my ears lasted for a day, and was exactly what I hear now, and which started about six months later. 'Course it could just be coincidence. Anyway, I am genuinely concerned that the various whines of an old Landy aren't doing me any good, so will be using them more in the future.I have (mild) tinnitus, I never do anything about it other than wishing I could hear "the Sound of Silence".
I did hear there was supposed to be a sort of cure, something about getting a noise generator to make a noise that sounds the same as the hissing you can hear and then playing it constantly until your brain cancels it out.
Dunno.
But my Dad had it and it fecked up his piano playing which obvs p!ssed him off.
When driving a long way in my Kit Car, an open roadster, I used to wear a flying helmet, that blocked the noise a lot, but I have also been known to use ear plugs. They work well too!
