Hello all, I recently purchased a set of Fostex FE168NS, I own different Mark audio's and wanted to try the competition...they have been playing on the shelf for 200h at low volumes for breaking in, but now it's time to fit them inside a cabinet...I have built all frugal horn sizes with different speakers used, some where amazing, some not that great imo...I also have a set of Joan playing now with Mark Audio CHN120 ( playing great, the highs are really crisp but not fatiguing at all, bottom is still to be fine tuned but allready great) but my all time favourite is still and by far the fhxl with MAOP 10.2, this one kicks any speaker I have owned out of the game (many and some really expensive ones like wilson audio, bw 801d, etc...) . I also built the adjustable duct type with maop 10.2 with mitigated results ( https://sites.google.com/site/speak...iver/-diy-adjustable-duct-type-sddbh-sddbh-ad ), bass extenssion is better compare to FHXL, but that's all, no live feelings, no details in mids, no wide open scene, etc etc, whatever the settings I tried... anyway it was worth a try and they play great in the garage... last but not least, I am also building a set of Fonkens with A11MS and will add a set of Fonkens with MAOP's that I will recover from the adjustable ducts and replace with A10.3 or pluvias (no need of MAOPs if there is no detail and just to play loud IMO...)
Now comes the questions...
By listening to the fostex open air next to MAOPs or 11MS or ch120 , they are much much crisper and agressive in the upper range, and this scares me a bit...
I am not sure about what cabinet to use, I planned to use the adjustable ducts when purchased, but with the mitigated results I had with MAOP's I won't be using this design...
I would like to use floor standing speakers, not 2m high, and maybe a front mouth this time...
Are there any floor standing Fonken designs for this speaker, can I use designs made for other Fostex like FE168∑, in case of Frugel-Horns, should I use the XL or the Joan???,
Does anyone have some great experience with them?
And if I would like to calm them, does anyone EnAbled them allready, are there any other mods I could do, I just don't want any bsc filters...
Thank's,
Yves

This has a higher Q than typical FE, so it will probably work well in FHXL.
Looks pretty good 30° off axis.

It will work in a 13 litre Fonken, doesn’t go really low. F10 about 60, XO 4th order to a sub at 80 Hz (F3), no HP needed.

But they won't offset any of its up to +10 dB of stepped response like a compression horn will, i.e. what I assume is what Yves refers to as no BSC.
I have only ever had to use passive BSC in one of the hundreds of loudspeakers we have built.

I was going to suggest that but he said he couldn’t do 2m tall.
It works with FE166x/168e∑ and FF165wk, this driver seems to fall in-between.

Ok thank you for the advices, so I will try it in an fhxl as I better know what to expect and will start from there...
Does anyone knows a good front mouth design for this speaker? I would also like to build one to compare with back mouth designs,

Well, as GM says, it's a midbass BLH spec. in T/S terms so should go reasonably in FHXL from that perspective if a reasonably sized box is needed. One of HM's midrange horns should do OK too, although they won't get as low (no reflection intended, they're not designed to). Assuming you want a relatively compact box though, a front terminus design is probably not ideal. If I get chance, I'll take a gander at some point.
Thank you for your proposal but I will try the Victor, they are just above 1.5m high so they might fit in my living room, and I have some painting ideas that might suits them really well and make them looking smaller...
Victor plans received yesterday, thank you Scott they look amazing...
wood purchased this morning, now, let's start the build...
I have some ideas for the side finish to give it a sleeker appearance and raise the WAF drastically, opinions are welcome...natural wood finish front and dark paint on the back or dark paint front and natural wood on the back, and curved forward or curved backward?

I'd be careful about using the terms 'far left' and 'far right' lads... Some people might get the wrong idea. 😉
