... of course... now the problem is that I want a pair of these Fane drivers (or at least a chance to hear 'em), and they're NLA.

How the heck did I miss the photos of the driver in the OP until now??!?!?Let me share another project that I am venturing into
A few months ago I managed to buy a pair of Fane 15" full range speakers - unfortunately production of these drivers was stopped earlier this year due to low demand; as far as I know I bought the last pair in Europe
(if anybody knows about any leftover stock in Europe definitely let me know
So I have decided to start this project now
These beasts would normally require huge boxes (250+ liters each when sealed) so I decided to go for a higher Qtc value and compensate the lows with EQ and amplifier power
Cabinet will be sealed, 65 liters with Qtc = 1
15mm baltic birch plywood (wanted 18mm but it is quite an unobtanium over here these days or freaking expensive)
Here are some simulations:
Max input power will be 90W per channel, that's where the drivers will reach their linear xmax
View attachment 242464
At that power I will get 95.4dB at 1m at 24Hz
This is for one speaker so +6dB for two speakers plus room gain which is 15dB in my living room at 24Hz

Impedance:

Phase:

Group delay:

Of course I will use extensive DSP to correct the magnitude response (it will be much needed anyway...)
Some pictures and a video in the meantime:

The bottle is for scale
Stay tuned!

Some more pictures:
I actually put some polyester wad around the driver too but forgot to take a picture of that
There is also some vibrodamping sheets + felt on the back wall inside but forgot to document that too
The speakers are now ready to be DSP-d, will post some results later this week
Stay tuned!

Looking neet. Aren't they upside-down?

No, the drivers are in the bottom half.
The idea is that if I need any subs they will fit below in another cabinet (but I suspect that I won't need any)
In case you don't need subs, isn't the woofer way too far down for decent high-frequency reproduction? The woofer is already beaming as it is, having it mounted all the way down won't make things better.

The center of the woofer (ie where the highs are coming from) will be at ear height - so no issues with that

And finally the measurements!
Listening position (approx. 3 meters) one channel driven (right) at 75 dB
1/12 smoothing, no gating, no FDW
Highlighted is the corrected curve, the other is the original
Pretty good results I must say!!
Freq with phase:
IR
In this zoomed out view the lack of reflections can be seen very clearly - this is due to the beaming of the driver (which for me is a good thing and I know that it is generally considered bad)
SR
Practically no pre-ringing despite the very heavy correction in the low-end
Distortion
Max is 4.62% at 22.6Hz - for me this is pretty good - note that there was no HPF in the signal chain!
In real-life conditions I apply a 24db/oct. HPF at 23Hz
Waterfall
Due to my not-so-ideal room we can see some pretty heavy ringing at around 50-60Hz and below 30Hz
Please see here the mdat file for further scrutiny: https://drive.google.com/file/d/1k4Yjnnqfl7HpUvSRvt6m5cGky-FGlYVJ/view?usp=share_link
Now some subjective experience: (note that the drivers were used for a few hours only - they are very far yet from burn-in)
- sound stage has an incredible 3D (holographic) effect - I have never heard anything like this before (except for the 12" Audio Nirvanas)
- beaming is pretty strong (if I move my head like a few centimeters in any direction I hear a big difference) - this is inherent and you will have to accept this if you plan to have this kind of a sound system - this is a 'one-man show' strictly
- mids are exceptional, highs are detailed enough (surprisingly so!)
- bass goes down to about 23-24Hz (in my room) and indeed has authority and impact - and also very detailed - also suitable for movies (for a rumbling couch and yelling neighbors you will need subs though)
- I totally get the 'live' feeling - all the instruments and the vocals feel like literally being in the room - even with your eyes open you can 'see' them. IMHO you cannot achieve this with any multiway system (at least based on my experience so far)
- note that these single-driver one-way systems all tend to project the soundstage in the front, especially the phantom center - meaning that you will hear the lead singer at least 1 meter in front of the speakers (towards your head) instead of between the speakers. You will need to see/hear for yourself if you can tolerate that (I personally looooove it)
All in all I love them and they are freaking staying here!!!!!!
Next steps:
- get a pair of stands (you can laugh at me but it will be from Ikea) LOL
- paintjob (white using ultra-matte chalk paint)
I will document these once done (probably in a month's time)
Any questions are welcome

You are right, forgot to mention that then I apply a low shelf and a high shelf to shape the sound to my taste
Where did you get your felt from?
- Thread Starter
- #55
From a local (Hungarian) dealership specialized in sound damping. Unfortunately I cannot tell the original brand since it was re-branded by the dealership (I am sure that they are not the producer)

What do you mean exactly please?

To be honest, no
I always listen on axis only
I'm trying to find a company that sells felt pads big enough to go under a carpet. Haven't been successful so far.

I don't know if it helps but this is where I got it from concretely:
Zajcsillapitas.net - OVF SOFT filcesített textil lap
OVF filcesített, préselt, gyanta erősítésű textil lap. Hajlékony, többféle kivitelben és vastagságban, öntapadó és sima hátlappal egyaránt kapható.
And in the meantime I managed to find the brand too! (a little interweb digging helped
)They are made in Italy by this company: https://www.ovattificiofortunato.it/html/prodotti.htm
