| Speaker cone shape @pch300 Many thanks, I have a better idea of what's going on, and it gives me more to research. | |
| Speaker cone shape What I meant by "suck it and see", is reading the posts, despite any science or past design experiments, be that of cone shape, cabinet or any other aspect of the speaker design, the bottom line seems to be you have no guarantee that it will sound... | |
| Speaker cone shape Well this has been interesting. So though there is science involved and calculations to make, and I dare say the implementation of aspects of others previous design successes to assist with the design of a good speaker system, the bottom line is ... | |
| Speaker cone shape I'm beginning to realise there is enough known and unknown to keep your brain occupied for a lifetime :^).I have just built a set of 3 way units with new 8" Kevlar - 6.5" Kevlar - 4" Silk, and better crossover units. They are rebuilt in a pair of ... | |
| Speaker cone shape Interesting video. So there are advantages to flat drivers. How much difference you can actually hear is another question. | |
| Speaker cone shape I just had a look at Vienna Acoustics, even those are not completely flat, but very nearly, well that's how they come across in the images.They say: "The plane surface of the spidercone offers the advantage of precise, piston-like movement. Any di... | |
| Speaker cone shape Hmm, seems to be a can of worms then? | |
| Speaker cone shape But as the surface is at an angle the air can’t be pushed along the axis of the speaker only toward the centre. If you move something through the air at an angle the air doesn’t get pushed directly forward, it always moves in the direction of the ... | |
| Definitely lonely to be an audiophile @luisma31Impressive, I'm just curious how many do you have?I have three. Frank pram stereo 30 (modified), Lafayette LA224B (modified), Yaqin MC-5881A (modified). Three sets of home built speakers. Also a Bush VHF 41 radio and a NordMende Parsifal ... | |
| Definitely lonely to be an audiophile I value my alone time too, but I'm lucky that my partner Valerie is interested in my fiddling endeavours to improve the sound, and has input with suggestions. She also likes sitting quietly next to me to listen, as we share a liking for a lot of t... | |
| Warning: China-Hifi-Audio.com I have been ordering kit from China for years, never had a problem with any company I have dealt with. Customer service has always been A1, even when there is a problem with an item it has always been resolved quickly, often just sending a new one... | |
| FRANK pram 30 watts Ultra-linear Stereo tube amplifier The B+ went from 345V to 373V with the final (experimented with other diodes) UF5407 rectifier rebuild version. I have no Voltage specs' for the amp, so just took a guess that the selenium rectifier had gone up in resistance a bit since 1961 and a... | |
| Speaker Spike Philosophy I have a new marketing ploy. Sell everyone 16 screw in eye bolts and 8 bungee cords and suspend your speakers from the ceiling. It's so far out, it's bound to catch on. :^) | |
| 5AR4/GZ34/5U4/5Y3 SS conversion I have a thermsistor in the circuit, in fact two in parallel to slow it up even more. The Russian military EL84s in there will stand 315V and more with no problem, I have another amp that's been running them at 350V with no problem. Some commercia... | |
| 5AR4/GZ34/5U4/5Y3 SS conversion Well it certainly looks different :^)https://cursorium.co.uk/images/ssr-3.jpghttps://cursorium.co.uk/images/ssr-4.jpg |
