FaitalPro 3FE22 projects (nice little full range driver!)

I've built a 9 drivers array (3s & 3p) and I was thinking of adding some sort of waveguide to improve the vertical response a bit (I'd like to get a bit more high frequency even when standing) so I'm very interested in your little arrays with WGs.

I have a question for you: have you ever measured vertical dispersion at different listening distances with and without waveguides?

Thanks, Manuele

Echoing comments here on what a sweet little driver the 3FE22 is. Just built some ported boxes for the kids gaming rig (4 of). 230x15x90, 9mm ply, 75mm * 9mm square port, 75mm long (slot at bottom of cabinet), 2.04L box ex driver and port volume. No stuffing. Tuned at 110Hz. Internally the port is flared.

Powered with a cheap and cheerful TPA3116 amp... absolutely rocks.

It's got a lovely top end. Yes, it's somewhat directional though expected.

These will be HP'd to a sub (could have gotten away without this honestly) but in the meantime they're absolutely fantastic.

@xrk971 not yet. Testing mic comes out over the weekend. It'll be fronted by CamillaDSP, so will get tweaked as needed.

But very, very impressive right out of the box. I have speakers that cost a lot more than sound not as good.

Doubtless there are better enclosures to make though this is literally a kid's project - I really wasn't expecting solid performance at all. Quite surprised, pleasantly so.

Finally, I got a chance to set this up as a temporary left channel in my work room. When listening from ca 2 m away, horizontally on axis, it is actually pretty good. It definitely needs some distance. Also, I was able to hear some comb filtering (sort of like a flanger effect) when moving forwards and backwards, but only very slight.

I have plenty of 3FE22s, so maybe I will build up more of these and try some frequency tapering in a composed line - 5 modules of 4 drivers with 3 channel DSP and amplifier.

Any updates on this project?

I think I have to change my opinion about the small 4 driver array. I am listening to it for quite a while, since my final speaker for this position is still being built. And I must say, I started liking it. In its vertical sweet spot, it sounds actually pretty nice. Maybe one day, it will deserve a second one to the pair. I think two major factors why I started liking it are a little EQ from MiniDSP and the 300B amp powering it now.

My experiments with short array (4-8 drivers) showed that while it worked well in the midrange, i found too much beaming in the highs.
Solutions are, at least for me, deviation from fullrange. One can use single tweeter, or multiple tweeters curved, or shading, making it 1.5 way.

@adason

Do you have any experience with the commercial models? eg. Bose L1 Pro, JBL, Yamaha other line arrays?

I hear them quite often during summer time, during solo singer/guitarist performance, it's they are quite impressive for the footprint. However, whether that translates into indoor listening or long term listening, I'm not sure...

So this would be the baffle for the 5 unit Bessel array. It will be a learning object for two sided machining on my CNC, since I want to make the drivers back mounted. 12 mm birch plywood will be used for it. The rest of the box will be ordinary 18 mm MDF or some leftover chipboard, somewhere between 5 - 10 l volume. So this box goes to the end of the list of projects, there are quite some above it at the moment🙂
