Trio15 PAP-Horn1

Here is Douglas Schroeder, Dagogo Reviewer, straight from the heart response to the Trio15 PAP-Horn1 that he received for a review:

It figures, the one genre of speaker I thought I could safely ignore through the years is the one I should have been paying closer attention. I had concluded through listening events at shows, dealers and audiophile friends that lower power and high efficiency speakers were not the way to go to attain to SOTA. What was I thinking? That higher power equals superiority? Likely. That nothing tops an electrostatic when it comes to cleanness and detail? Most assuredly. That low power/HE is ancient technology and inevitably the newer designs have surpassed it? No doubt. That horns are problematic, too finicky? Of course.

All wrong. These perceptions were all wrong, obliterated by the experience of hearing the PureAudioProject Trio15 PAP Horn-1. I have been pinching and kicking myself for the past several weeks as I have been romancing the Horn-1; pinching myself to see if this is not an illusion, that the experience is as magical as I’m hearing, and kicking myself because I have been a reviewer for more than 12 years and only now I’m relishing lower power/HE in a big way. The truth is that I likely would not have trod the low power/HE path had I not been engaged in the series of reviews of the Trio15 variants for PureAudioProject. I have several iterations with the Horn-1 to explore, but already the few configurations I have assembled would quality as most ardent audiophiles’ end game masterpiece. The previous versions of the speaker have led me to this, the Horn-1, a transducer that, if I were pushed to choose, I would select over most panel speakers you care to name.”

“I’m past the 200 hr. mark on break-in now and delighted at the transformation of the speakers!  They’ve become remarkably musical & very satisfying.  I can’t say that I’ve heard another speaker that provides the thrill of listening that the PAP horn gives.  I look forward to many years of enjoyment from them… Finally, let me express my gratitude for sticking w/me thru months of indecision.  In the end, I’m confident that the PAP Horn1 was the perfect choice for me and will provide years of satisfied listening!!
I hope all of you at PAP receive an equal measure of joy to that provided to your customers!! Thanks again & all the best…”, Ray S., Customer, US

With Trio15 PAP-Horn1 the border line between live performance and reproduced music simply disappears. Instruments become live… live in front of you… full body and with top-end clarity and resolution !

Open baffle design, the custom-made OB-A15Neo woofers, the sonic clarity and presence of our classic wood-horn, all contribute and make the Trio15 PAP-Horn1 to what it is; though if eyes are closed, trying to describe the speakers will probably end up with describing the instruments, one by one and as a whole, pointing to their position on stage and in space, and being moved by the beauty of the music and the emotional involvement these speakers evoke…

Just like all our Trio15 models, also the ‘PAP Horn1’ is a modular configuration that differs from other Trio15 models by the horn mounted on the middle baffle, and the crossover.

A word about the PAP-Horn1 crossover is not only an example for top-end audiophile-grade unit, but is much more than that. It was designed to allow customers to swap the critical audio components and choose their preferable ones; all without the need for any technical, DIY, or soldering skills ! The horn capacitor is screwed to gold-plated terminals, and therefor is interchangeable. At any time, this capacitor (as well as it’s serial resistor) can be swapped, allowing to evaluate different caps with your own ears and to choose the one that matches at best your sonic DNA!
Yes, so simple is this !

‘Trio15 PAP-Horn1’ is a very unique model ! It brings both, the sonic bliss of pure Open Baffle and the live feel of a well designed wood-horn, to a musical peak that we are most proud of… There is no greater pleasure for us than seeing so many music fans, in different places around the world being deeply touched by the music they love playing from our speakers… and we strongly believe that PAP-Horn1 is definitely one of a kind to long live with…
