Default Single driver best FR Project/Design

Hi, was wanting to build one pair of full range speakers. What would you consider the best single driver, full range and high efficiency speaker design or available plans?

Thanks for that, some very nice (and complex) looking speakers and horns. Am particularly interested in a single driver design. I saw you had a design that used the Jordan JX92 (Tuba) and one that used the Fostex 206 (Trumpet-sat), how would they compare?

You are going to have to refine that question. There is no best single project even with no constraints. every speaker is a balance of trade-offs.

But you no doubt have a room, a budget, size constarints, cobstruction constraints, kinds of music you listen too, what things are more important to you?

Default no best designs...

just a lot to try out.

I've heard lots of speakers. Many were $$$ , many weren't. I have a limited FR experience, but I am going to continue to push the same questions ...

What amp?
What room size?
What enclosure size?
What enclosure type?
What budget?
How complex an enclosure?
How "handy" are you (or will you have help?)?
What kind of music do you listen to most often?
How good are your sources?

My standard answer is no enclosure, an Open Baffle. But there are many excellent speakers and enclosures out there as well. A few sites of interest:

Thanks for the replies and sorry for the lack of clarity. Here are some constraints.

- Room size between 15m sq to 30 m sq (small room).
- Budget, drivers to be less than US$500 for a pair.
- Size. Footprint of less than 60x40cm (or 2' x 1.5') Height less than 2m ( or about 6').
- Kinds of music... classical, light rock, 70's rock.
- Amp: Tube KT88 P-P, 300B SET and Chipamp.
- Construction/design - simple clean lines type.

Prefer a to use a design that uses a single full range driver. I am relatively handy and don't mind the complexity of the enclosure, given that this will be my only pair of stereo speakers (will build a separate HT system).

Michael Methe claims he was successful in cloning a Rehdeko and this speaker has more realism than his AER MD3! Unfortunately he doesn`t give any information about this project.

Big box in a small room ... might be pretty easy to over-load it (do you have more than 1 room to choose or is 15-30 m^2 just an estimate -- the difference between the 2 extremes is enuff to make a difference). Classiscal music often requires big dynamic swings. Rock not so much, but usually needs a solid foundation in the bass. Budget enuff to buy any of the medium or less expensive full-ranges.

This suggests drivers in the 6" range. FE166/167/168, FF165, Audio Nirvana. Guys i'm sure i've missed some, help me out? Room may be too small for a bipole with a smaller driver -- how close to the wall do you need to place the speaker? (probably applies to Iris & Hiro too)

BIB would be just within your height restriction. Demetri, or a Metronome. Iris or Hiro.

Dalek or Auston wouldn't satisfy simple, clean lines.

Uhhhmmmm

*pictures exploding heads*

Bookshelf size (in cubic litres anyway) for that room, IMO.

Cheers!

Default eeyore

thanks for the question,

the TUBA is excellent and for 20-30 qm correct,
constructed 1982 and until today one of my best creation.
For the JX92S the best bass ever get max SPL enought,
translate the feedback.

The Trumpet or Schalmei are sat horns and need a sub,
like my corner horn, the soundstage might be a little bit better,
because of the indirect radiation, I prefer the B200 from
Visaton, read the feedback from Lawton , he compair it to
his Edgar system and done it with modified FE206.
The Schalmei is minimum better and larger.
