    Actually I don't think anyone in this thread did ask about larger corner horns ;- )

    ... but that's ok.

    There's a guy I met in (if memory serves) Henniker NH who has a pair of K-horns that have had pretty much every thing about them but the grille cloth (and the folded horn itself) modified... and, I've gotta say, they sounded absolutely superb; about as transparent-sounding a pair of loudspeakers as I have heard (and, mind you, I've got a pair of Quad ESL-57s upstairs which are no slouch in the "transparency" department).

    Even the stock K-horns aren't bad -- and they're only a little bigger than my Altecs ;- )
    Wouldn't mind having a pair if I stumbled across some at the right price. The value is in the cabinet -- as was Col. Klipsch's wont, virtually all of the components inside 'em were pretty pedestrian (although earlier examples used better quality drivers than later ones did).

    Agreed! A custom pair of corner horns were the best and most enjoyable speakers I've ever owned.

    The Daytons, although not much time on them and not currently being used with a 120hz subwoofer, sound very direct, bright, with amazing detail and separation. Using a frequency generator, they had output to about 100hz, but were missing the bass in any music mounted in the open baffle.

    Call me crazy, but I'm going to pick up a pair of Monitor 5Jrs tomorrow and will be swapping in the Dayton full range driver and disconnect the tweeter. The cabinets should be about the right size, and the PR should make for interesting bass response...

    Picked up the 5JR speakers and they are a nice example! Having owned these speakers before, they are very enjoyable, but suffer from being too large for small speakers, and too small for large speakers. Having said that, I'll be pulling them apart to create full range driver frankenpolks! >:)

    Yup! I disconnected the tweeter, soldered new wire on the binding posts, then connected that wire to the full range driver. I also used some strip insulation to build up the difference in the new driver.

    The result is very favorable with decent bass response and dynamic response with excellent imaging. I don't know where these PRs are tuned, but they seem to work well with the Daytons, and fill in the low end when combined with the cabinet.

    The cabinets are a great size (0.75cu/ft), the passive radiator adds an interesting aspect if the tuning is close to the original, and the tall cabinet puts the center of the full range driver about 12" from the bottom of the cabinet. I might make a small plate to cover the tweeter opening and see if that cleans up the look enough to make them usable; the stock grills even still fit!

    The stereo separation, detail, and imaging is amazing for near to mid-field listening, and the speakers really do disappear. I was worried by putting the drivers in a cabinet that they would sound boxy, and you do lose the bipolar drivers, but they still sound very open and transparent.

    No chance of a new baffle so you could fill in the tweeter recess and also recess the FRD at the same time? If you plan on keeping this driver in this cabinet, I see it being worth it.

    To continue my full range speaker rabbit hole, I just pick these up. It's a pair of Fostex FE206E mounting in a 1" plexi open baffle, with a pair of Fostex FT17H super tweeters. The crossovers are mounted in a pair of external cases, and I'll crack them open tonight to see what components were used.

    Nice find. The 206E can be a little piercing -- just be forewarned.

    These will start as my speakers in my office at work, so I'll test them this weekend with a subwoofer to cover below 200hz.

    I believe you need two passives per active woofer.

    The previous owner/builder used them with a single ended KT88 amp, and mounted the baffles on mic stands to make them bottom heavy. Not sure how he designed the crossover, but clearly some decent time and money were spent on these.

    Cheap experiment to try: IME, there is a small improvement to be had w/ the 'bearded whizzer' tweek. I have found a small improvement to be had by putting a little AcoustaStuff (alternatively, you could use Dacron fiber pillow stuffing) between the main cone & the whizzer. Just a little; very fluffy! Too much & it will over damp the cone!

    More elegant, I suppose, than my use of large New Hampshire rocks :-/

    Classy! I actually like the look of stone and wood, but your baffles have a delightfully simple look.

    Took 5 minutes to make 'em -- I am nothing if not one lazy madre.

    I cut a piece of wood in half, freehanded the holes with a jigsaw, and mounted the boards on the round cutouts with a few deck screws & my trusty Milwaukee drill.

    They were just test jigs for 8" FRs -- better than just sitting them on the floor :-)

    They might be a bit much for near field, but a successful test anyway.
