I'll snap a shot later today for you.Any pictures? I have a love for old drivers.
Mono - can we talk mono?

I really love that cabinet, it looks great. I have a NOS knight cabinet still in the box that i need to put together. I have a nice Stentorian driver i want to run in it. Wish i could find a cab like that in my area.
Picked this guy up recently and to my luck no output. It’s another one in the works.

Congrats on that beautiful cabinet and driver!
I have a single 501S1 I acquired years ago, more info in my blog.

Ohhhh that’s one pretty driver! I love those Alnico drivers, fantastic!

I really love those coaxial drivers, I have a couple RGF Mass and stentorian drivers that I absolutely love. I need to build a nice baffle, yours is gorgeous. That needs to go on a magazine cover!
this is one of my RGF mass drivers playing after I restored it.

Small world, I enjoy your blog very much. I have an affinity for Japanese idler turntables like you seem to have. I think I'm up to near a dozen, working on my Realistic Mark 8 is next up.Congrats on that beautiful cabinet and driver!

Thanks for visiting the blog!
I'm just doing finishing touches on the Mark 8 article. It will be added to the Japanese idler series soon.
Here's the Mark 8 on mono duty.

Very nice, did you have to have the idler wheel resurfaced? If so, how does it sound compared to a Neat 68h.Thanks for visiting the blog!

Yes, either the P58 or the P68. I've always wondered who built the Mark 8, some have said it was US made but I've always thought it looked Japanese. I'll try reconditioning the idler first, thanks for the info.

I have no experience with the P68/68H, which seem to be the less deluxe models - same motor but simpler main bearing, the platter and chassis also don't look as massive.
Yes, I've seen those posts.
FWIW, the brake fluid trick worked on the idler wheel of my "motor unit-style" Mark 7.

Replaced my 18in Jensen PMJ with an older Jensen M-18 field coil in my mono speaker. It’s technically the same speaker, same come, pitch, material - aside from it being a field coil. Sounds faster and brings out more details, not to mention it digs even deeper in the base notes.

Hello
The topic is very interesting. While I was going through the links and attachments in this thread I have some questions.
Where does mono end and stereo begin?
Is it possible to call an audio system monaural, where the left and right channel speakers are as close to each other as possible. Or for example coaxial drivers of the left and right channel are next to each other in the same cabinet. So if we zero out the distance between the left and right channel drivers, are we making the setup monophonic? Or is there some distance to the sweet spot where this sound will be perceived as monophonic. Or can only a system in which the addition of left and right channels is done "electrically" be called monophonic?
It seems to me that the appeal of a monaural system lies in the fact that the sound comes from one point, not two, as it is realized in stereo.
Or are there other important secrets of monaural sound?

Cool thread.
I am looking at putting a single b and w vm6 speaker in my kitchen.
I have been looking for a way to make this work, bluetooth, etc.
seeing this thread, could I use a stereo to mono adapter to hardwire my single speaker to my HK av520 ?
using a converter like this https://sweetfootpedals-com.3dcarts...-to-Mono-RCA--HANDMADE-IN-THE-USA-_p_331.html.
it looks like it would need an adapter from the rca out of the converter to the two wire speaker connections.
has anyone have experience doing this ?
the HK has a spare speaker output.
let me know what you think.
thanks

Hi bruno80918,
That converter you linked above is only line level - you can use it to combine stereo to mono, but you'll need a mono amplifier after it. I suspect that it uses resistors inside to combine and isolate the inputs from each other. Another option is this transformer from Edcor: https://edcorusa.com/products/s2m-s...stereo-to-mono-coupling-matching-transformers
If you want to go down the rabbit hole on the technical issues about using transformers for stereo-to-mono, take a look here (from setup1 here at AK): https://jelabs.blogspot.com/2016/04/stereo-mono-line-level-mixer.html. (Oops - Joseph discussed it in this thread - look around post 196. )
Once you've converted the line level to mono, you could use a mono amp - here's a modern example: https://fosiaudio.com/products/subw...l-frequency-and-sub-bass-switchable-amplifier
There is a speaker level stereo to mono mixer I've used before - it was a transformer made by Speco, model number TSM-30. But unfortunately, it doesn't seem to be currently available - at least I can't find it.
If the receiver has a mono button, you could of course simply attach the speaker to whichever output that gives mono (I don't know enough about your receiver to be able to tell if it offers the option to output mono.)
Hope this helps.

All opinions are worth what you paid for them
but IMO if its got 2 channels, even with the speakers right next to one another, its stereo. Mono has a single amplified channel regardless of how many speakers it has.
The closer the speakers the less noticeable separation you get though.
Endless debates on whether running that through a 2 channel setup makes it sound as good as it would run through a single channel. No idea on all that, but where it has appeal is you can often get the amps fairly cheap for what they are and if you have a lonely speaker and mono recordings its a good way to put all those parts together without spending dumb money. Also if you're after background music and don't care about being in "the zone", mono is fantastic. For a good while when I worked at home, my music source was a 1940s console stereo being fed from a sat radio tuner. I didn't have any convenient way of setting up something to give me stereo, so I ran that console specifically because it didn't matter and just filled the room with sound. I set up a similar thing at a bar, using a 1940 Stromberg-Carlson radio and a bluetooth receiver. Its not a thundering powerhouse but its fine for background music.
