Advice? Single full range open baffle design?

Can you advise with you would do and need to calculate/simulate?

There really isn't a 250 words or less answer to this sorry.

You can try starting to read books, or online articles about "how to design speakers" ... and then try applying some of that knowledge to:

I guess by 'do stuff', you mean play with different sized baffles/positioning/tilting etc. ?

Yes....  but just going with "what sounds good" can be (fun, so try it, but) a path to confusion.

Thanks again. I may start dipping my toes in both of those options, i.e. reading books and being open to a long term plan to build knowledge. I have a hunch, based on how I operate, that I may get lost in the technical thinking though. I'm a musician and while I have good technique I learned by experimenting, improvising and doing. I now know theory, but I was not wired to use theory as a starting point. Perhaps I haven't changed... but I can try  I am aware that experimenting practically can be a path to confusion-which is not what I want... perhaps I can experiment while it's fun, and where it gets frustrating, try to bolster my knowledge to take next steps.. Just thinking out loud  

I have, by the way, made a few steps forward in this project, which I'll post about below

It really depends on what budget you have in mind to spend and whether or not you wish to pursue trying other similar or even lower powered SET amps. The Glow in the Dark website I shared above is a fascinating read for open baffle speaker drivers, and the history of triodes that followed up to the release of the 300B. If I were to make a call on which single coaxial driver size would suit an open baffle design the best, it would be the 18" version from Lii Song F18:

Thanks, I have been reading the glow in the dark website over the last week, and have been loving it. I really love his approach, using the Telefunken enclosures with interchangeable front baffles and experimenting with different drivers. In terms of budget, what I seem to enjoy is experimenting with a variety of options before going for the endgame. I suppose the 18 inch, due to it's size would solve the problem of bass and would be a smart way to immediately get directly to the end... I picked up a pair of Lii Audio F12 drivers from SNA last weekend. They are in tiny baffles and are predictably lacking bottom end. I'm considering having a pair of open baffles built to the recommended specs on the Lii Audio website. I may also use those baffles to alternate other 12 inch drivers in for fun. I'm also looking at having a pair of the open backed Telefunken style enclosures built ala' Glow in the dark and rolling different drivers. It looks like the Telefunken takes 10 inch and lower. I'm considering whether to scale up a bit to allow 12 inch and under or whether to build as they are... I'll post more about that later today.

Thanks for chiming in and probably a reasonable question. I want a good end result after some experimentation, learning and fun on the journey. I'll post later about some specific drivers and designs I'm considering working with. Ideally, someone would say, that driver will operate best with this baffle or enclosure design... 

P.s. I feel like my original post says what I 'm after: feel free to go to the start and read that.

Mate it's all excellent food for thought and a massive help. I'm glad to know there's a sort of science behind it all. Pretty amazing really

Thanks for sharing your journey.  Im curious where your heading.

 A big plus of OB is DIY  ease of "build". Quicker then getting some OB made would be to DIY some rough baffles OB eg  recycle some waste ply or boards. Loads gets tossed and dumped from commercial sites and building sites. You just need a jigsaw and a screwdriver.   Down the track you could pretty up the baffles  if they give you what you are looking for.

That's an awesome suggestion, just getting dumped ply/boards! I could definitely get a lot of enjoyment out of putting some rudimentary baffles together myself. Have drill, jigsaw and table saw so its something within my ability, which is part of the point-that it's practical and doable for a beginner... As for where I'm heading, I'll try to post more tomorrow

These 12" drivers also look good for OB design.

Thanks mate. I'd spotted those and am watching. Any idea what may be better between the Philips and the Zenith? I ended up going for the Coral/Peak 8CX drivers which will hopefully arrive next week, so I've got a couple of different drivers to play with so far.

Which other ones do you have?
