Not for a while. I'm less inclined to change speakers, as the Super Pencils are kinda big and heavy. They sound pretty good too.:yes:

Who is running "Full Range"?

Here's my DIY fullrange speakers. Bi-amped with 2a3 and 300b amps. Goodmans Axiom 80 at fullrange, Axiom 22 at fullrange and Fostex 925 X'over at 14KHz.

I'm not running full-range at the moment (not in the single driver sense at least), however, I would definitely like to try a pair of these in ported cabs (Wharfedale Super 12). Beefy SOB's, aren't they? Still trying to figure out when the Super 12 was at it's peak in terms of development/performance. Maybe early '60's (They made the alnico Super 12 all through the '50's and into the mid '60's).

Wow! How much does one of those weigh?

Very nice looking effort there :thmbsp:
What are you using for the digital processing?

Four! You not only HAVE four 80s but are using two in each cab! Sweet! I guess there's nothing worth doing that ain't worth overdoing! (I mean that in the best sense).
That is just awesome.

Oooh.... I'm jealous... Besides Wharfedale, the only other full-range drivers I'm interested in are the tube-era Goodmans (The Axiom 80 is the proverbial bee's knees). When you compare the alnico Goodmans woofers and full-rangers to the alnico ones that Wharfedale made, they almost look identical, so it's not surprising that they sound similar.
I was about to ask if it's a good idea to put, say, TWO full-range drivers in the same cabinet (like two 12" full-rangers in one cab), but you just answered my question. I bet those dual-80 cabs sound incredible with old blues and jazz stuff, or ANY blues or jazz for that matter.

I still haven't figured out what combing is (That sounds distinctly like something DIY'er's say to each other). But anyway, would it work if the two halves of the enclosure were isolated from each other in some way?

buddy of mine runs these in an Eliptoflex cabinet. Good sounding single driver setup. Pretty beamy (as to be expected from that large of a driver) and does not go anywhere near the 28hz-20khz range advertised but still a good sounding setup.
These full range 12 inch Eminence Betas over H-frame Alphas are currently my best all around effort. I use a Bottlehead 2a3 for the 98 db Betas, a Topping T-amp for the super tweeters and Yung class D plate amps on the Alphas. Instead of passives I use an electronic crossover and there's no lack of bass with the H-frames.
Beautiful, but how do you classify that as full-range with a single driver?

I agree, very nice but a three way. Three drivers and a three way XO.
IMHO a single driver full range is just that, one driver trying to do it all with no XO. In this instance it is a full range driver running no XO but with a bass driver crossed over and a tweeter crossed over. This is not different than many designs that use a mid driver running full range but still a 2 or 3 way IMHO.

Full range drivers in open baffle speakers are commonly used as wide band mid-rangers with woofers to augment the bass and super tweeters to add some sparkle and air on top. The idea is to allow the full ranger to handle as much of the frequency range as possible so that the negative effects of the crossover can be lessened. My OB's are but a rehash of Martin J. King's research and proven design.
I currently use an electronic crossover which I tune by ear and pay little attention to it's inaccurate settings. But I've probably enjoyed these OB's as much with the full rangers running wide open straight off the amp and with a single cap on the tweeter. I switched the cheap horn tweets for the far superior Neo 3 planar tweets. The H-frame woofers push lots of air with the 300 watt plate amps. They don't plumb the depths but in exchange offer natural weighty bass with fast transients. All I need is to cover the bass viol which goes to 41 hz and they do.
Yes the OB's are 3 way but wouldn't my single driver Frugal Horns with a sub be a 2 way?

Yes.
I think the intent of this discussion was more towards that single driver no XO point source type designs of which many are shown as an example here. Once you add a XO (only needed for more drivers) then it is no longer a single driver full range setup.
From the OP...
"I've been contemplating building a pair of "full range" speakers, using a high-quality 6" or 8" driver in a transmission line or ported enclosure. I'm looking for a tall-slender-deep profile. Considering Fostex, Fountek, or Seas for a driver. I think it would be an interesting study to see how the lack of a crossover influences the sound."

With the full range drivers it seems you can get two of three things but not all three:
1. High sensitivity/High efficiency
2. Great mids and good highs (smaller full rangers)
3. Great mids and good lows (larger full rangers)
My little 4" Fostex drivers have #1 and #2 in spades, but I like the sub to get the very bottom. I like depth in my sound and in my experience, a sub does that with most speakers regardless of whether they are full rangers or not.

OK so the 3 way OB full ranger is off topic. Well here is a full range single driver OB Betsy sans crossover. This is by far the simplest build on the planet so please ignore my attempts at gussing them up.
A pair of $100 drivers, some plywood and hinges is all one needs to sample OB and FR. I know a guy who built these and told me he preferred them over his Omegas.
