Frugel-Horn XL for Alpair 10.3/10p, Fostex FF165wk, more

You would have to ask the fellow in Spain(?) who commisioned the design and built them.

The A7ms will have more bottom, whether it is better comes down to “what makes it better for you?” .he A7ms and the A5.2/3 are the 2 smallest of the 3 mono-suspension drivers.

I may have already done some preliminary work with the larger bowls.

No thread specifically on the Blanda-kens, but lots on the Blands bowls.

But i dug, i did do one with the big bowls for the CHR70, tweaks for the A7ms should be straightforward, the new basket will make it easier. Could probably be rolled into the A7ms plan-set with only the base planset paid for. email me if intersted.

@FourEars: looks like you have a nice frequency response plot for your FHXLs. It is surprising to see how much room placement impacts response. You read about it all of the time, but seeing different graphs really drives it home. Thanks also for the details on gluing magnets, I wouldn’t have thought of them shorting out and reducing power. Great to know to avoid future problems.
 
Even with a driver as capable of running full range as the A10s, I’d still be inclined to high pass filter them when using a sub. I recently saw a review by Randy the cheapaudioman for a couple of models of Emotiva powered subs with a high pass filtered line output on their plate amps. That’s a feature that I think is long overdue.

You can do it either way.

Adding a HP to the FHXL should allow greater levels.



Those have been around for awhile. Almost always a passive (and therefore a bit of a joke), proper active HP would be a nice feature.

FYI, according to Emotiva’s Steve George, they are active circuits using op-amps, and from the owner’s manual:
2. Line Level Outputs
Connect the Line Level Outputs to the input on your power amp if the Flex Sub is providing bass management for your system. These outputs provide an audio signal that has been processed by the user configurable high-pass filter portion of the internal bass management on the Flex Sub.

Eric, and anyone else interested, the room that I had my FHXLs in originally was very open with one entire side wall of the room open to an entry/stairway and a large passway beside the speakers opening to the dining area. I’ve moved them now to my basement listening room which is smaller and closed and couldn’t be happier. The room gain seems to fill in where needed resulting in a very full soundstage. I added 20 grams of well fluffed fill to the front chamber (running empty before) and that really tightened up the bass which I had previously described as “loose” without diminishing the quantity of bass. I had a fellow speaker builder/friend over for a listen and after a warmup song or two played Sia, “Cheap Thrills”. If you’re familiar with the song, about 30 seconds in the bass comes in, Wham! Wham! and he says, “No f#*$ing way!” and jumped up to make sure that no other speakers in the room were playing. So, yes, the room and placement are paramount with these speakers it seems. Mine have found their home.

Hello, this is my verry first post on this group, and first of all thank you for all the amazing informations shared on all the frugalhorn pages, I have read all pages and learned alot and I am now completely passionated with those full range speakers, I am from Brussels, 48y old, and been testing many different systems since my 20, and all I can say it's that I love my xl's with maop10.2 on my 300b's way over all my other systems costing up to 25 times more...I builded all 3 sizes the little with fostex WK85, and the mk3 and Xl's with maop's, Now comes my question, is there any way to pay the designers for making frugal horn plans for bigger sizes FR speakers like cube audio's 8 or 10" and new Lii silver 8 and silver10, I would be verry happy to pay for this work and share it for free with the audiance if allowed, my skills stops at wood building and I would really enjoy testing some bigger units in this beautifull design, and I'm guessing I can't be the only one dreaming...Yves
 
Yves,

Custom designs are certanly doable (based on manufacturers spec). email Scott or myself. We have done designs for Cube, and pretty much dismissed the Lii drivers (no realistic data).

A FH for drivers greater than what fits into Joan are not going to be FHs. The Cube 8s might work in Joan, but given the high prices you now pay for them, one might want to do something more specific & finely tuned. The 10s would need their own design.

dave
 
I will also add that if anyone would like to finacially support the exsiting FHs, make a donation to diyAudio, they are the only ones who benefit financially from the small donation required for FHXL and Joan plansets.

Flat-pak manufactures hopefully are making money on their kits, they are supposed to donate for each FHXL/Joan shipped. And Martin gets a software royalty (one time) from each of those flat-pak makers.
