bbx customer review

I have since 2014 been experimenting with the new BBX driver, and now think it’s time to share some observations.

In order to put the comments in context, my previous speaker was an open baffle design based on the excellent AER MkI driver with a Seas base element to handle anything below 80Hz. 2 separate 47Labs Gaincards was used to bi-amp.

So, on to how the BBX stands up to this:

  • Detail and instrument separation is outstanding, actually the best I have ever heard.
  • The ability to handle complexity, both rock and symphony is excellent. The previous systems strong point was smaller ensembles
  • Live recordings are particularly interesting. It really is very good at recreating “the room”
  • Imaging is slightly less sharp then with the AER MkI system, but given the size of the BBX, a trade off I do willingly.
  • No need for any Sub, I have the LF set to 18Hz, and I am using a curve where 1000Hz is the zero level, then +2dB up to 20Hz and -6dB to 20kHz.
  • The speed of the bass in unlike anything I have heard before (of course apart from live music)

 

My system consists of

  • MacBook Pro w Audirvana and Tidal. Room correction made with LA Convolver using Menubus. The filters created with Accourate. I only play cd quality and resolution.
  • USB to Gustard X12 with digital coax to a 47Labs Shigaraki Dac
  • Amplifier Primare i30. The 47Labs Gaincard I also have (25W) is not able to play loud enough with a 4 Ohm speaker
  • Interconnects and speaker cables are 47Labs OTA, power cables and filter from Supra

 

The BBX unit is mounted with double sided foam tape to a steel plate screwed into the wall. The wall itself is made using concrete board instead of the normal plaster type. This was a chance I took, thinking a stiffer board would yield a quicker recovery when moved by the driver, and the sound I get proves this

Again – I am very happy with the sound. I think once you get use to this kind of bass sound and overall detail it will be hard to go back and listen to the regular driver based systems. The one improvement I am still looking for is eliminating this rare sharpness in the highs that sometimes is there.

I think the BBX system opens the door for many audiophiles to move the system into regular rooms. There might of course be some compromises, but at least for me it is very much worth it.

Customer Gallery

In the category “customer gallery” we show the “living rooms” of our customers. Here an exclusive system in Russia. The chain of the absolute top class components  is completed by our BD4 with ecentric horn. Our valued customer is excited and sent us a self-measured frequency response. Our Excenterhorn with BD4 driver delivers a nearly linear frequency response of 80 Hz – 60 kHz.

Bernadetta Sunavska listened the Axjet

An article of concert organist Bernadetta Sunavska published after a real music audio event:

Recording organ music is a special challenge for loudspeakers.  The ample acoustics in many church rooms endanger the audibility of quiet and quick passages, whilst the organ’s full sound hopelessly overstrains most speakers.  How often has one turned up the volume whilst listening intensely, only to jump up in panic the next moment to kill the volume when the loud sound set in again?  There is hardly a recording opposing the live experience of a concert to such extent, which is why to me, listening to recorded organ music is an annoyance rather than enjoyment.
I am pleasantly surprised that these questions did not have to be raised in the first place, as a pair of Axjet speakers recently played back a contemporary organ work of almost one hour.  Finally, one could duly enjoy an enormous sound spectrum.  Each and every articulatory detail could be heard, from subtle changes in the acoustic colours to vast tone clusters.  One had the impression to be right at the source of the resulting sound.
With these speakers I have discovered a whole new dimension of listening (not only when it comes to classic music), and that is something I am absolutely grateful for.

Customers about AER

Some of our customers have been experiencing AER products for decades.

Mr. Werner Schäl summarized his satisfaction in a forum post:

“ I am using the AER BD3 by Filip Keller for 4 years now. I’ve never used a speaker for such a long period of time. The reason is simple: I am always pleased to listen to these speakers. My electronic gear changes quite often for my system is improving by the time. The loudspeakers are able to reproduce anything that is fed to them. At the beginning I had some problems with “crisp” highs, but this was was definitely caused by wrong electronics and cables for the use of these loudspeakers.
I’ve been compulsively into this hobby for 30 years now. Of course, I will never be able to enjoy all the products available, but almost everything I’ve heard yet (at high-end trade fairs, in private, at showrooms) I estimated far worse compared to my listening experience at home. And there, the Keller-drivers have the hugest part in it.

Of course this is not yet perfect, but expanding and testing makes the whole hobby so interesting to me. Also, I’ve already heard a Visaton B200 in different cases, but I think it didn’t sound as fresh and open and clean in the heights as the BD3 chassis.

When hifi-driven people listen to these speakers, so far everyone has been enthusiastic about them. Of course, they are expensive, but as a reward one finds a lot of work, a lot of development work and experience in the chassis. If I calculate what I might have spent on speakers in the last few years, my choice was reasonably priced after all.”

 

We would like to thank Mr. Werner Schäl for his kind contribution.
