The other gearboxes may whine as well, it is probably the straight cut gears in the transfer box.

And I doubt if there is any point in having stereo unless you use headphones, because you will never be in an optimal position between the speakers to take advantage of it.
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!

You can hang these speakers wherever you want them, so spacing would be fine. Whether you'd benefit any more than anyone within a hundred metres at the volume you'd need is moot....
 
As @TurbomanI'd be reluctant to use headphones whilst driving...though have seen millennial ****s using them...as one needs to hear surrounding noise/sensory for safe driving - it's that sixth sense thing we all need for good driving.

I'd have agreed with that until I used to get a lift to work with a chap who was completely deaf, and was not only a very good (and aware) driver, but also one of the kindest to his car, very gentle on all the controls. I've tried to emulate that, and became really critical of some cars for reasons that most miss. I hated the Alfa 147 purely because there's no 'normal' rubber washer between the clutch cable outer and the bulkhead and you can feel the engine through the pedal - silly, but once you've noticed it becomes an obsession... Possibly all triggered by my childhood fascination with the way my parents drove. Dad, the genius engine designer was really hard on everything, switches etc probably 'ought to be strong enough' - but Mum the doctor was very smooth and always brought the car to a stop with no perceptible jerk. Dad didn't!

I once got pulled by the police who'd been sitting beside me in traffic (in the Serpentine doncha know) while wearing on ear 'phones in a convertible. I knew they were there so it was really my wanting to know what they'd do. They were a bit unsure if there was any offence until I pointed to a car and asked if they knew whether it's driver was deaf. Likewise I guess if you've got your megawatt system cranked up to 11.

It 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...:eek:

Re the JBL, it's only 40 watts total [2x 20w sub-woofers] but does the job quite well
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 why

Being an old fogie who grew up with valve technology, I get confused with the claimed specs on modern loudspeaker systems. If a unit has four seperate speakers in it and the spec says output is 20 watts, is that 5 watts per speaker? I have a single speaker that is 50 watts rms and it is much louder than a multi speaker unit claiming to be 50 watts

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 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.

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.
If you did it in France with even one headphone/earpiece you'd get done.

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!
TBH I think deaf drivers like spec wearers would have summink on their licences.
confess I didn't read upthread. My bad!:(:(:(
Once knew a guy with only one eye who drove very well, and a woman with two eyes but she could only see out of one at a time, again drove fine.
The one eyed guy was once waved out of a junction into the path of an oncoming vehicle, luckily he had turned his head right the way round to check with his one eye and sho nuff saw the lorry. Stupid prick poliss!;)

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.:(:(:(

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 note that French law doesn't mention ear defenders btw, they'd be better than nothing. (I used to use a pair with some Sennheiser wireless 'phones built in).

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!;)
