I have been quite vocal about how much better I think EI transformers sound compared to toroidal, even powering the output stages of a power amp. Of course some just refuse to accept that transformers can sound different. I find that as long as the stray field is kept away from the load then the dif...

Shoddy

Found this on my travels. An up firing mid bass in an Ikea bowl sphere with four tweeters attached round the periphery. Same sort of idea as a sonab or Carlson speaker from the golden age of everything (1970's). I think that is a sub at the bottom. https://i.imgur.com/ahQ3SKB.jpg Missed a trick the...

I hate to say it's sounds better than the lenco it replaced ,especially with these temp measurers , but it bloody does

Better be careful what you say. I'm quite surprised the Lenco fan club hasn't turned up here yet to say you are wrong

I'm just obsessed with spheres now. I think they look ace and better and less imposing to my eyes than the usual boring speaker shape.

Cut the holes in the other tweeter pod today. This 7s going to be a marathon not a sprint. In the past when doing prototypes I have been in such haste to hear it that I rushed and cut corners. Can't do that now, I need to take it steady and produce something that not only sounds good but is a pleasu...

You are really giving this speaker some thought, you should have been a speaker designer for one of the major manufacturers, think of all the facilities they have open to them. Thanks Dave. Doc used to say I over think things, my wife says so too. I'm not quite right in the head :grin: Often at wor...

It occurred to me that the steel hemispheres have a 3mm wall thickness rather than the 5mm I used when thinking about acrylic. That 2mm extra radius makes quite a difference in volume - 13.3 Litres for 3mm thickness vs 12.77 Litres for 5mm thickness. In this case I think I can make the partition wit...

Thanks :guiness; Are you admiring my balls :lol: The holes need tidying up as I said and enlarging by half a mm and then I need to do the other one. I tried this on one of the other balls that now have the wrong size holes in just to check it works and it all goes together very nicely. I put some sa...
