CEATEC 2014 Audio Report, TAD, Pioneer and Technics

facebooktwittergoogle_plusredditpinterestlinkedinmailby feather

Hello there,

This sure was a pretty full period audio-wise. Lots of events all over the world and im glad to say i pushed forward new developments with Project Ryu.

CEATEC Exhibition as expected was held this month and i was looking forward to some new audio products. Looking around i found Tamura Booth showing off their transformers.  In a glass box they also had one of their vintage jewels. Take a look:

Next interesting booth was Pioneer’s. A lot of demo DJ setups and noise but in a corner i found TAD. Nothing new here but i could snap a couple of driver close-ups of the Reference One Speaker System. Also they displayed the Compact Reference CR1MK2 but i got to say i was more attracted by a TL-1601a they had in between.

Next to TAD, Pioneer Professional (… i know)  showed their PA speakers. GS-WAVE Series sure look promising and it is a pretty interesting move for Pioneer to go back to the old days of PA with the concept for this series. Pictured below is the WAV-LENS, mid-high speaker featuring acoustic lens and can do a whooping 145dB peak. Coaxial 2″ drivers, 250W MF and 160W HF and dispersion measures 110 deg H and 50 deg V.

Technics had a very nice room, showing a bit of their history, had 2 listening rooms and they presented their Reference System R1 Series. Products were displayed with inside view as well.

The R1 Series has 3 components, SU-R1 Network Audio Control Player (aka Preamplifier), SE-R1 Stereo Power Amplifier and SB-R1 Speaker System.

Technics SU-R1 Control Amplifier is a 17kg preamp featuring Technics Digital Link (a digital connection between Technics Components) and it is powered by two R core power transformers.

SE-R1 Stereo Power Amplifier sure looks like it can handle the work load. Normally Technics tried to come up with something different and even if IMHO they really lack imagination naming these technologies, i really appreciate their effort. So SE-R1 features JENO Engine (Jitter Elimination and Noise-shaping Optimization) … [great name guys!], GaN-Fet Driver, (now this is something worth looking into) and LAPC (Load Adaptive Phase Calibration).

The third component of the R1 Series is the SB-R1 speaker system. Now in the past Technics has proven its speaker design ability with some really amazing products. Now on this blog i don’t really want to write subjective impressions on sound so if you are curious about this system go ahead and find a place where you can listen to them. And this goes for any system from any brand, its your money, if your willing to spend it go and decide for yourself.

What i can do is give you some pictures and info on how these systems are built. So back to Technics SB-R1, these speakers claim 100kHz , and they reach that but at -16dB! Oh well… so lets just throw away the specs and look at what we have here.

We have 4 x 16cm drivers in 2 separated bass reflex enclosures (2 per enclosures), we have 1 coaxial MF/HF unit which looks pretty interesting in its own isolated closed enclosure.

Below you can see a cutout through the speaker and some details like crossover board. As you can see there are no exotic components in the crossover.

All in all it was a really fun show and Kaihin Makuhari is a great place with lots of cool futuristic buildings. I hope you enjoyed these pictures and that you will visit again soon.

All the best!

Tokyo International Audio Show 2014

facebooktwittergoogle_plusredditpinterestlinkedinmailby feather

Between 23rd-25th of September, Tokyo International Forum hosted the 32nd edition of TIAS (Tokyo International Audio Show). This year’s exhibition had about 31 exhibitors and some interesting lectures however it was set in the middle of the week and even with a national holiday on 23rd I’m sure many could not make it.

This year there were some interesting products from Ocean Way, Daniel Hertz, Wilson Benesch, Constellation Audio and DartZeel that i got a chance to listen and inspect visually, but the rest were pretty much same ol’ same ol’. I will get into some details with some of these units and for the rest i kindly ask you to visit the gallery below.

Bowers & Wilkins

In the B&W room i saw displayed details of the top mounted tweeter used in CM6S2 and CM10S2. You can see what the Decoupled Double Dome technology is and the back chamber.

Also pictured is crossover of the smaller models in the CM series. We can see B&W uses first order filters and Mundorf capacitor.

Wilson Benesch

My attention was caught by their Endeavour Loudspeaker first because it features an isobaric bass alignment, something you don’t see very often and second because the enclosure is made from composite carbon material.

In a speech, i was able to capture, they talk about the advantages of composite materials to reduce enclosure resonances and they state their design philosophy. There is also translation in Japanese.

 Ocean Way

This year they brought the Montecito Reference Monitor System. A 3 way design all aluminum diaphragms so the tweeter dome and the midrange and bass driver’s cone is made of aluminum. The tweeter is loaded by a wood waveguide.

What i liked about this loudspeaker is the high diameter midrange, a 10 inch unit and, in my opinion, a very good choice for crossover points, 160Hz and 1.6kHz.

Gato Audio

AMP-150 and CDD-1 were displayed and i really found their aesthetics very pleasing and interesting. The amp is pretty powerful rated at 150W/8 ohms/channel.

 Accuphase

Their room was impressive as always with some really good speakers to showcase their electronics. They setup a demo of PS-520 Clean Power Supply unit and i would like to mention it here. For more pictures please check the gallery.

Daniel Hertz

I got to see the M8 Speaker System this year. This high efficiency loudspeaker can be used as nearfield monitors with an 8 inch mid-bass driver and a compression driver in a 2 way bass reflex alignment. I was able to get some closeup shots of the drivers.  Crossover point is at 2kHz and one speaker weights 25kg.
