Default Has anyone heard the Fibhorns from ebay yet?

I know there was this thread 3 years ago but there wasn't anyone that had tried them yet.

So my questions is has anyone tried the Fibhorn that is being sold on ebay yet? I'm looking for a pair of near field speakers to use with my computer, with a small SET amp (Miniwatt n3) with just 3.5 watts so I am looking for something efficient ideally. I'd like to use the FE126En ideally in there.

The reason I'm looking at something like this is I don't really have much in the way of DIY skills, so something basically done for me would be ideal. I was thinking of a Planet 10 flatpack but I don't know how to solder yet, so I'm not sure how well that would go.

I am only vaguely familiar with the Fibhorn, but have paid attention as the designer & manufacturer is a P10 client.

I wonder if fibonacci number progression makes a sensible choice for a horn profile.

I can't see it doing any harm. Whether it brings any real gains is another matter, but it's different, or at least presented differently, which is nice to see. I hope they do well for them.

Sounds interesting, the claimed low response is 38Hz. The enclosure weighs 11 lbs (sans driver). MDF weights vary by grade but one source says 2.19 lbs per sq ft. That would yield a weight of over 11 lbs for the box (sans interior partitions). I wonder if foamcore is used for interior partitioning?

MDF weights
MDF is not a sensible material.

Sally sent me some snapshots a while back and the ones of the inside show playwood (18mm would be my guess) construction.

Per the ebay listing;

The .5" MDF cabinet material is inherently non-resonant, and even more so because of the structural rigidity from the internal bracing parts.

I would not buy any horn made from MDF.

1/2in MDF is not 'inherently non-resonant' -a matter that is dictated by physics (or 'laws of nature' if you prefer). It is impossible to eradicate panel resonances, let alone with 1/2in MDF. All you can realistically try to do is shunt them to a region where they are less likely to be excited. In this case, the internal panels will brace the external ones somewhat, thereby raising their resonant frequency / BW. Whether it is sufficient to move them above of the cabinet's functional BW is open to question. Since MDF is not especially stiff, and has a relatively high density for a given thickness, I doubt it. Which doesn't mean I don't wish them well -I do. The more cottage-industries there are the better. I would like to see one in a quality void-free ply.
