  1. As others have suggested you need speakers which are designed specifically to be used with valve amps and vast majority of modern speakers are not.It might work but you will not extract the full potential of either the valve amp or the speakers.A much safer option is to use a valve preamp. Valve amps behave differently electrically to SS and Class D which makes them far more sensitive to speaker loads. Here is a really good overview of those differences- https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=13&cad=rja&uact=8&ved=2ahUKEwjpmMSgot7lAhXIOI8KHYJyAi0QFjAMegQICRAB&url=http%3A%2F%2Feducation.lenardaudio.com%2Fen%2F12_amps_8.html&usg=AOvVaw3yR-sxIbdxmCEYEpUnE30J
  2. The Goodmans Axiom 80 frequency response. Not much different to the Altronics $14 driver really.About $3000 versus $28.Much more efficient though. As I said just enjoy them for what they are- the good and the bad.
  3. How was the imaging in your room? It occurred to me their more recessed imaging might be a positive in your narrow room.
  4. I really do not understand spending too much on wide range drivers.Especially wizzer coned ones.Their appeal lies in being valve amp friendly and offering excellent phase purity and many offer high sensitivity which also can bring sonic benefits.But they are compromised by their nature so will never be perfect.Or even quite close to perfect.They are something that should be enjoyed for their strengths and from what I have heard those strengths are just as apparent in some of the cheaper alternatives.Maybe more so.
  5. I suspect the very low moving mass is why it sounds nice.It is very lightly built and that is probably a good thing.
  6. Part number is C200A. As used in the Straight 8 project discussed here a few years ago. I think one with an open baffle 15 inch woofer to do bass would work well. I tried 4 on an open baffle H frame and that sounded pretty good.Then I ruined it by removing the wizzer cones off the bottom two .
  7. This $14 driver from Altronics sounds nice and works well on an open baffle.I prefer it to the sound of most wizzer coned drivers I have heard -including Philips, Fostex ,Coral and Lowther.It actually has a bit of the Goodmans Axiom 80 sort of sound which is by far the best of that type of driver I have heard. Of course the underlying appeal with these devices is an accentuated presence range .Not accurate but that is probably not the point.
  8. B.S. material more like it. https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=12&cad=rja&uact=8&ved=2ahUKEwiO1_yostrlAhUaAXIKHfWADD4QFjALegQIAhAB&url=https%3A%2F%2Fskeptoid.com%2Fepisodes%2F4026&usg=AOvVaw2UTSrxQV1bYqfP_uiPnel8
  9. Have the Bybees been activated though?That makes a big difference. You need to get several cockroaches ,bury them in the ground in cow horns ,leave them there for 12 months,dig them up on the full moon and sprinkle the ingredients [ known as Solution 468] all over the Bybees.That is called bio dynamic activation and it will unlock their quantum purification. Just wear gloves when you handle the Solution 468.I forgot to do that and now my fingernails grow around 5mm every day which is a bit of an inconvenience.
  10. Yes listening chair in front of the low wall and speakers out from the opposite wall.Sofa where your equipment is now [an effective bass trap] And avoid rear ported speakers .Or ported speaker altogether. One of my rooms is quite like that although it is 800mm wider.Gale 401s work really well in there.Larger rear ported speakers do not.
  11. As long as it does not lead to Hypexerbole.
  12. Yes I would generally agree with that.The Seas A26 kit however is not your normal two way design because it has no crossover on the mid/woofer at all .The driver rolls off very well without needing to add anything.So that just leaves adding a very simple first order crossover [a capacitor] of an appropriate value to the tweeter.. Also there are well documented and measured versions of this design using different tweeters with suggestions for those capacitor values to suit.
  13. The Seas A26 kit would be an good and easy build.It has a very simple crossover so that bit is easy and cheap.It would work well with a wide range of amplifiers too.It comes with an expensive tweeter but you can swap that out for a much cheaper Seas or Morel horn loaded tweeter [as used in the Devore Orangutan which also uses a modified version of the woofer].
  14. Incredibly well engineered speakers.You can really hear that because they sound very seamless and coherent.Which I suppose is what you would expect from Harman with all their engineering expertise and resources . Maybe they have engineered the life and musical soul out of them however?Which is not to say they sound sterile or cold because they don't.If anything they are quite warm and rich sounding but they also have a distant sort of imaging which is a bit unusual.I guess that might suit some music and rooms but you would have to be sure you were OK with that sort of presentation.I can see that some people might like it.Certainly some speakers are too forward sounding .The F208s are the antithesis of that.
