SB Acoustics SB17CRC35-8 Measurements!

September 13, 2016 Posted by gornir

 

The SB17CRC35-8 mid-woofer is generally a low distorting driver. It uses a thick, stiff and light Carbon fibre/Rohacell sandwich cone with an exotic look and appearance.

Even though the overall performance is good, it doesn’t have the same clean distortion profile as its sibling SB17NAC35-4.

SB Acoustics SB17NAC35-4 Measurements!

I’m not a super fan of hard cone drivers due to their limitations regarding severe cone break-ups and distortion profiles, but here’s an exception.

The SB Acoustics SB17NAC35-4 driver has all the benefits of a hard cone driver, but with the limitations in full control.

The cone geometry of this driver is excellent and it has some slits in cone in order to reduce the cone break-up. It dampens the break-up so effective that the 10kHz break up doesn’t show up in the third-order distortion plot at 3.3kHz. The overall distortion profile of this driver is very good. In fact it’s one of the best hard cone drivers I’ve had on the test bench.

Kensho Two – M2 Construction Released!

March 26, 2016 Posted by gornir

 

Due to different circumstances there has been a while since I’ve published a new loudspeaker design, but here it is!

The Kensho Two – M2

“Kensho” is Japanese for “seeing nature.” It means seeing one’s true nature; perceiving the self, but can also in Zen Buddhism mean “a brief experience of enlightenment”.

This loudspeaker is a small 2-way using a 5” mid-woofer and a horn-loaded ribbon tweeter in an 8 liter enclosure. As an option the loudspeaker can be built using an 11 liter enclosure.

The horn-loaded ribbon tweeter has its own very unique sound character and it blends nicely with the mineral filled Polypropylene cone mid-woofer.

This moderate priced loudspeaker performs very well and it delivers a very generous soundstage with a large height, width and depth perception.

I love using it with my 35W tube amp, which can play it strong with authority and without problems.

If you hate ribbon tweeter sound – don’t read any further – This loudspeaker will give you plenty of “ribbon” sound.

Enjoy!

A New Blog Update!

February 28, 2016 Posted by gornir

 

Hi everyone,

It has been a long time since my last Blog post!

I’ve been occupied with family concerns. First of all we have moved to a new house and now I finally have a dedicated listening and measuring room.  Secondly my Father sadly passed away just before Christmas and that has of course had an impact on my available time for loudspeaker constructions.

Even though I haven’t updated the website for a while, I have continued working as much as I could on some new projects.

By now, everyone who has followed my Blog must have noticed that I’m a sucker for stand-mount loudspeakers and to no surprise there are hopefully two new stand-mounts released and published during this spring.

One of them is nearly finished and I’m only waiting for the time and opportunity to find the time to do the last measurements and fine tuning and then publish it.

The other one requires a new enclosure in order to be finished and I’m waiting for better weather in order to do the necessary woodworking.

Both constructions are low/moderate priced loudspeakers. One uses a 5” mid-woofer paired with a cost effective ribbon tweeter. The other one uses a 7” mid-woofer paired with a waveguide tweeter of similar size.

Later this week I will publish some photos and comments on the Stockholm High End and Sweetspot Hifi shows I attended 20-21st of February, here in Stockholm Sweden.

By for now!

Regards

Better late than never! 🙂

Here is the final part of the NHT 2.5i review.

NHT 2.5i review part 5!

August 22, 2015 Posted by gornir

 


This NHT 2.5i review is a small summer project of mine and it will be divided into 6 parts. The review will include, dissecting the loudspeaker and examine the enclosure build from the inside as well as a lot of measurements, including driver unit measurements and loudspeaker measurements paired with some subjective listening reviews.

Depending on the outcome of the measurements and simulations, I might also come up with some suggestions on how to improve the design.
