For example, quick sketch:

with 3/4" wood, the height would be 15", 12.5" deep and 9" wide.

The 2" deep block around the port shortens the overall line length from 33" to 31".

Oddly enough, if you vary the height, the width changes on this layout, so you can have thin and tall or wider baffle and a bit stumpy.

Not that I've been musing this for a while...

Thanks Colin,
I've settled on these:

The final version I am having built, by the kindness of Woddturner-Fran (as the name suggests he's a dab hand & just finished some Fonkens), is this one: http://spiralspeaker.web.fc2.com/aaa...ng-ag180z.html

These cabinets are originally for the Fostex FE126E drivers & I'm wondering what, if any, changes to dimensions should be made?

Any comments/changes appreciated before wood is cut,etc?

Fair enough but I'd have thought the drivers were different enough to require a number of changes to the cabinet (line length, line cross section etc). If you go ahead, it may be worth fitting a removable sub baffle so you can substitute drivers if it doesn't work out with the Jordans. Not a cheap or easy build for an experiment.

Having said all that - if you go ahead, do report on the results!

BTW, may be worth posting a link to this on the fullrange section to get more feedback.

Colin,
Took your advice and have a removable baffle - inital reports are that there is plenty of bass from this diminutive speaker with a slight tunnel sound to the midrange which can be fixed with stuffing, I hope.

I will be picking these up next week to mount both Jordan drivers & have a good listen & some tuning - currently, they are with WoodturnerFran who kindly built them for me!

These speakers had their first audition tonight in WoodturnerFran's house - they sound very good & the bass output is amazing for this size cabinet - you can feel the air being pushed out of the forward firing ports if you put your hand near it.

No sign of the tunnelled mid-range that FRan experienced earlier.

They sounded v good driven by push-pull tube amp, SET amp, DNM amp & digital amp with all sorts of music.

These of course, are initial reactions which long term listening may modify but all 4 of us there felt that they were pretty exemplary!

Fran took photos during the build & I'll post here if anyone is interested?

What a silly question - of course we're interested! Well done for an innovative build.

Thanks All,
Colin, it's Fran who did the build - all credit to him - I wouldn't have attempted this without the equipment - that's why when he kindly offered to build me some speaker cabintes I decided why not get something I couldn't attempt!

As an aside, a guy who has Dynaudio contour 1.3 MK II speakers and was looking to upgrade to 1.4, took them home last night to audition & he rang me this morning to say they are as good as they have everything the 1.3's have with added clarity!

ANyway, more impressions will be posted in time - here are some pics for you visually orientated people

First off the cabinets glued & screwed without JX92S drivers installed - a1 foot rule in the pic gives an idea of size of these diminutive cabinets

I will post some more later today - have to run now
