Dear all,
I am planning on a new active 3 way build with the following drivers:
Bass: BMS 18N862 (Expensive driver but I already have one).
Midrange: Faital 12PR320 (Used in proven designs).
High Frequencies: Faital HF1440 + 18Sound XT1464 (Compression driver specs are promising for high resolution and the horn has been used endlessly with high praise).
DSP and amplification by a Hypex Fusion FA503.
The woofer and midrange will be in a sealed enclosure. Both for saving volume and in my opinion most midranges sound better sealed than ported.
Placement of the drivers can be seen in the attached sketch.
What are the thoughts of the experts on the driver placement on the initial baffle sketch? Any objections?
Thanks in advance for your opinions!
Best Regards,
Koos

I would count on some experimenting with the CD-Horn combo. The LTH142 seems the usual suspect. I’d also evaluate listening requirements and room acoustics before targeting on such a relatively narrow beaming horn.
Hello Markbakk,
Thanks for your reply.
Both horns are 60 x 50 degrees, do you think the LTH142 will sound different than the XT1086?
About the narrow output, my room is 4,2 by 4 meters. The wall behind the loudspeakers is a full window of glass. The ceilings are 2.7 meters high. This is one of the reasons my choice for controlled directivity, to minimize reflections. I will only use one chair for listening, so it’s no problem when the sweet spot is very small.
Do you agree that horns are a good choice when dealing with high ceilings and/or a highly reflective room in general? I am not that experienced with room interaction, so any advise is welcome.

You don’t want a horn just because. It has to be part of a bigger (directivity) solution. Controlling the ‘beaming’ of mid frequencies (200-300Hz and upwards) is the real challenge. As you intend to use a horn that will do the beaming for you from about 1k and up, you still have to think about those two quite important octaves inbetween. In other words: set a target (treating your room acoustically can be part of the solution) and work it out. And don’t forget to experiment, have fun and enjoy results while they might not seem perfect.
Thanks for sharing your thoughts.
What about using the BMS 12C382 instead of the midrange driver and horn?
Would this be a good partner when used in a sealed enclosure with xo point around 200Hz to the 18N862?

Good question.
Here is an answer to it:
Taipuu Speakers Loudspeakers - Taipuu Speakers
Doesn't the three way share some similitude? 😉
But why discard your initial thoughts. Troels Gravesen 'The Loudspeaker' come as an inspiration and a documented project along your initial plan to me.
Markbakk and Allen answer i agree with.
Simulation software ( Vituix or another) can help understand what is at play from the loudspeaker side of things and give insight of what to expect from room ( more or less).
From your initial sketch i wonder why you placed the 12" over the waveguide?
