X-Shape, next generation waveguide

X-Shape Horns

X-Shape horns represent a breakthrough in horn design, achieved through advanced Finite Element Analysis (FEA) simulation, this innovative technology unlocks a new level of acoustic performance:

X25 for 1" with a BMS 5530: X-Shape Horn 25
X33 for 1" with a BMS 5530: X-Shape 33 Horn
X34 for 1.4" with a FaitalPRO HF1440: X-Shape 34 Horn
X40 for 1.4" with a 18Sound ND3TI X-Shape 40 Horn
note: The accident on the X40 in very high frequency is due to diapragm breakup of the ND3TI, not to the horn

Comparing to a common OS waveguide the loading capacities is way improved, allowing low x-over and a constant uniform psyckoacoustic directivity behavior pushed very high.

On the RCF 350ND passive filter is even possible, but as this driver have a sooner THD increase comparing to others, a passive cross over at 1250hz is advised:

The vertical constant directivity make also the horn not sensitive to your vertical listening position, here the response of a X-Shape 25 horn:

Full PLA horns

Full PLA horn doesn’t have return and are cheaper, they can be prepared to paint freely with coated where it’s needed to be then entirely sand to 240P.

You can follow this process for paint : How to Finish my Horn

From X33 including, PLA horns are made in two parts (for now), so it make sens to ask raw surfaces for X17 to X25 as they are printed very finely and in one piece.

Most of our clients use the X25 raw.

Wood horns

Plywood horn versions have 3 (in-box version) or 4 (free-air version) full returns as described in “The round-over return and round-over face” upper.
They have the “throat section like” in black matt PLA, that can be paint by us as an paid option, wich the color you wish.

Wood horn are done by batch for allowing the best price, generaly one session by month.

We strongly recommand to read the midrange narrowing and beaming page for understand how this aspect is important for every horn integration for every brand.

We provide full 4 or 3 returns for free air usage, it can be the regular round over or the FEA simulated one that allow 33% less space occupied by roundover:

return kit

This FEA return has another advantage, it create a more progressive loose of directivity in the horn low-end control, allowing to be closer to woofer radiation and to have, thanks to this, a better woofer/horn directivity match.

They can be glued, or fixed with M4 screw with PLA specifics threaded insert.

In the case you glued it you can completely paint it:

4mm radius

Or with a 3 returns, integrate is easily with in the cabinet:

4mm radius
We can also see that it’s very easy to transit from a tinier radius like 12mm to the 25mm of an X25.

Of course you can also do it like this yourself in the front baffle:

wood return

In this last case you may can appreciate a 4mm face roundover for easier embedding, we can print it with this radius for a perfect feet in your baffle :

4mm radius

The full round-over fluid return is the most important point of midrange narrowing and beaming removing, the horn allow it by a direct ending at 180°. Each recommended round-over return radius by horn is the ideal one simulated in FEA.
