How Trio15 w/ Voxativ PiFe was born

Just with the beginning of 2017 we have received a question from Rachel at Grant Fidelity, whether her customer who just ordered the Trio15 with Voxativ AC-1.6 can change the order to have the higher grade, wood cone, Voxativ AC-PiFe. To date we did not try this driver but it looked like it can match and has the potential with our Trio15. Well, we took that challenge and a week after, a set of PiFe drivers arrived and were installed on our in-house Trio15.

We mounted it and just connected the XO we had for AC-1.6. It was immediately clear we need to increase the L value a bit to get the high bass and mid playing right with the PiFe. L2 was not needed so we removed it, and that’s it ! All the rest stayed without a change !  Trio15 Voxativ PiFe started singing and did it 24/7 for a week! Once break in was over it sounded full body, with solid sonic mass, and with all the clarity, resolution and sonic finesse Voxativ drivers are popular for! We felt extremely happy but the real challenge is still to come and this is customers satisfaction!

While loving this set so much, dismounting the drivers and sending them was not easy, however, knowing what pleasure these will provide to their new owners compensated on the ‘letting go’ feeling…

Few good weeks passed by and after few mails about all being good and how break in is progressing we have received this email.

Tim W. : “I have listened to both the Voxativ PiFe driver and the woofers separately and can state with certainty that there is magic in the crossover network. The system is extremely precise throughout the frequency range. Time-phase errors are nonexistent (to my ears). The sound is highly engaging. I haven’t yet experienced any listener fatigue. To the contrary. I’ve had to drag myself away from listening sessions.

I have several sets of speakers, including the Gallo Reference 3.1s and Magnepan 1.7s pictured. Fine speakers all, but since the Pure Audio Project set arrived, I’ve been contemplating unloading the other speakers and therewith about half of my rig. I really listen only to your set anymore. My usual listening position is 9-10′ from each baffle, with the speakers spaced 9′ apart. Some might consider this nearfield but I get extremely good imaging, with a beautiful soundstage.

Normally I run the speakers with a Nagra Jazz (tube) preamp feeding either a First Watt F2/J (an F2 into which Nelson Pass has inserted the SemiSouth input JFETs) or an Audio Note 300b amp (shown tubeless at the moment). I have also used a custom bel canto Fidelio (tube) preamp that’s had the full Ace Tomato Company treatment by Matt Cramer

and a one-off original Fi Audio preamp built by Don Garber. The F2/J is my favorite solid-state amp with these speakers. I run the Gallos through a Cary preamp and monoblocks, and the Magnepans through a custom 4P1L (triode) preamp made by Radu Tarta and a Bryston 4BSST2. It’s these last two configurations that I may move on from.

Usually I transfer LPs to half-track 1/4″ tape via a modified Technics 1500 R2R and DeHavilland 222 repro head stage. Playback is through either the Technics or Tascam 3030 decks. A TEAC X2000M mastering deck backs up all through a Bottlehead Repro Tube Headamp. So I mostly listen to tape, then SACD/CD. I like jazz, classical, modern, rock, electronic – pretty much everything, but especially if it’s well-recorded.”

Ze’ev,

I love the speakers. Love them. I find them perfect for me. I’ve usually had a revolving suite of 6-8 different sets at a time and it’s been a pain. Hard to move around, sell, ship (especially Magnepans), and drove my wife crazy. That has ended. The flexibility inherent in the open baffle concept and your business model mean that this is the last and final speaker system for me. I wake up looking forward to exploring fascinating new sounds every day. Thank you!

Nelson gives several possible configurations for including the F4 in such a setup and I’ll try those too. May need to hack up a few cables in the process, as some are fairly non-standard! ?, Timothy W., USA”
