diyAudio reference speaker project

[rabbitz]

A section in the Wiki sounds like a great idea. As long as the newbie knows where to look (big neon sign maybe).

I think the Vifa driver combination of P13WH-00-08 and D27TG-45-06 that was originally proposed is probably the best choice for the Newbie as they are resonably priced, easily aquired, well behaved drivers, you only need a simple crossover and would end up with a good result. You could also add a variation using the P17WJ-00-08 for those who want a bit more bottom end (and this is from a Peerless user.......I can say Vifa).

what is the "wiki" ?

If newbies are going to copy this reference design why does it need to be so simple? If you use drivers that have already been extensively used and are available in many kits like the Vifa P13/P17 and the D27, many DIYers will still go looking for designs using some more exciting drivers. Why no do something a little different? Isn't that, after all, a big part of the DIY spirit?

What about something more exotic, like the Vifa XT tweeter, or the Peerless HDS phase plug midbass drivers, or Vifa MG series, or some of the Seas standard line aluminium midbass units? Or the Vifa M18, a driver which is said to compare well with a popular Scan Speak driver, yet at little more cost than the Vifa P17.

Or perhaps I have missed the point of this thread ...

For the Wiki, have a look at the top of the homepage. That's what a mean about having a neon sign to show them where to find them.

I think you are right about the spirit of DIY of trying different drivers etc, OK for the seasoned or adventurous DIYer but I think for the first timer something really simple would be the go and with proven drivers.

I prefer to go from concept and design everything as it's more satisfying (get some disasters along the way, but hey.....part of the game).

I think you might have hit on something about existing designs available........maybe all it needs is links to the better designs. Such as if someone wants a Peerless TL, then link to the Peerless pipes.

rabbitz, I'd run on like an idiot about the Wikipedia earlier in this thread and wondered why noone had responded to it. I had no idea myself that wiki was already a section of diyaudio.com!
So it already exists and hasn't yet been used to build a speaker projects library yet? I'm a bit dumbfounded. But as I also said earlier, I'm no webmaster, so perhaps it really isn't as simple as it appears.

[rabbitz]

Yeah I saw that post bradley. I didn't realise they were the same thing.........duh. I thought the Wiki had disappeared but it's still there.

Hey.....I haven't worked out how to insert a quote yet either.

The idea I was trying to generate, was an inexpensive, yet good project that would serve as a reference to other designs, so a member could say "I've build a different speaker using such and such tweeter or crossover (or enclosure) and it's improvements are as follows....over my reference speaker.

If many of us have exactly the same reference speaker, then our recommendations for other designs or modifications of this design, in this, or any price range would be more objective rather than almost completely subjective.

Rabbitz-
So you're on board with the P13WH-00-08 and D27TG-45-06 ? We then can look forward to your remarks on the comparison to your Peerless speakers. I have about 6 pairs of speakers (kits and sort-of kits) in this price range to compare to. (under $200. US)

A search on the P13 turned up

this site which looks like a good source of info for the newbie...wonder why this site isn't linked?

Here is Scott C. Blaier's Esquire....
5 litre, with a sloped baffle, but a rather complex x-over.

Can't seem to locate a plan using a single cap....Do we want to start with the simplest x-over? My Windoz is starting to yawn...BBL... Help anyone?

[aggielaw]

Well, it looks like with have both sufficient interest and a sufficient number of ideas. Why don't you "old-timers" at this nominate someone to set up the project, post it in the "Wiki" section (gotta go check that place out in a minute), and we'll go from there.

I'm actually ready to build, although I will need to go out an buy all the materials and tools required. But when we come to an agreement on what we'll do I'm ready! Well, ready as a newbie can be, anyway...

The TLb (althou a bi-pole version) is such an animal (there is a thread on the TLb on this forum), and my buddy Chris, has replaced the Linn tweeter on his Daline with the same (but tweaked) Vifa tweeter. After 2 or 3 months of playing with the XO he ended up with a single cap too. Anything more "sucked the lif out of them". It should be noted that the Dalines are downstairs in the HT and he is using a set of well executed Buschorns with a modeified Foster FE103A in his main system (sometimes with a helper tweeter, sometimes not).

paulspencer-

I believe your suggestion quoted above is a good one, but without input from those experienced with these drivers, especially comparing them to the P13, we're left to our own devices.

Certainly all suggestions are welcome, and I'll happily go along with the consensus, I'm simply trying to find the common ground among those interested. The responses I'm happy to say, seemed to go along with these drivers and far outnumbered the naysayers.

It would be nice if one of the resident gurus wanted to design this speaker for us...(hint, hint.) But my guess is that it might be a greater cost to them than benefit.....we'll see.

Other suggestions of designs should consider future availability, that should rule out "clearance" and sadly, Audax drivers.

Designing by committee could take a while, but maybe not, afterall the "just do it" philosophy has its rewards. Every speaker I've built has been a pleasant surprise in some way, and definately a learning experience. The serendipitous effects of synergy are imposible to predict.

Perhaps interested ppl could post a desired style and/or price point. Or if this small bookshelf fits the bill.

I'll be buying multiple drivers to start and planning the next project with them (unless they are higher priced ones.) I'm tempted to think in terms of a disassemble-able tower for the second one, even if the initial design enclosure is small. Built-in stand, TL and TLb, by changing the back panel and interior woodwork. I just hope my Audax HT is completed by then, otherwise I'll have to do some serious shop cleaning.
