SB Acoustics SB29RDC-C000-4 Measurements!

December 5, 2016 Posted by gornir

On the testbench we have the SB Acoustics SB29RDC. It’s a nice performing tweeter which shares several features with the more expensive Satori TW29R-B tweeter.

There will be a comparison between these two tweeters in a later blog post.

For measurement details see:

SB Acoustics SB29RDC.

Update!

Due to a measurement setup issue, the distortion measurements has been updated for the Satori TW29R-B tweeter. The distortion profile for this tweeter is very good!

SB Acoustics “Satori” TW29R-B.

What’s underway!

November 26, 2016 Posted by gornir

 

I thought I should give an update on what’s in progress at AudioExcite.

Currently I’m building a floor-stand version of the “Concentric Three”. It uses the very nice KEF SP1632 mid-range co-axial driver used in the KEF R-series. This time I’ve paired it with dual SBAcoustic SB17NAC35 mid-woofers in a small furnishing friendly size.

 

 

I’m also preparing for a loudspeaker review of the Bowers & Wilkins 685 stand-mount loudspeaker. It will be reviewed, dissected and I will probably give some suggestions on how to improve this loudspeaker. Be prepared for a lot of measurements, cross-over simulations and listening impressions.

The review will be divided into several parts, much like previous reviews I’ve done on e.g. NHT 2.5i and Wharfedale Diamond 10.2.

AudioExcite – 5 year anniversary!

November 6, 2016 Posted by gornir

5th

Time flies so fast!

I can’t believe it, but the AudioExcite website has been up for five years now. It has really been fun to work with the website and its contents, even though it’s very time consuming. I have met new friends and have had many rewarding e-mail conversations during the years.

I have great plans on how I would like to develop the content on the website. Unfortunately, I always seem to have too little time since I also have a day time job as well as a family to take care of.

You DIY loudspeaker enthusiasts can help me!

I would like to do a lot more driver measurements, but since I’m not sponsored I need to buy all the drivers myself and that costs a lot of money. If you have drivers you would like to have measured, you can send them to me and I send them back to you when I’m finished with them.

If you have drivers to be measured, fill in the contact form and I will get back to you.

Another way you readers could contribute to are by donating some money. All donations I receive are always invested in new drivers and loudspeaker designs as well as in the running costs of the website.

I’m extremely grateful for all contributions.

 

Thank you!

Best Regards

SB Acoustics “Satori” TW29R-B Measurements!

October 26, 2016 Posted by gornir

 

This time we have the TW29R-B Ring Dome tweeter from the SB Acoustics “Satori” series on the test bench. It’s a very robust built tweeter with a nice measurement performance.

For measurement details see:

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.

For further details see:

SB Acoustics SB17CRC35-8.

 

SB Acoustics SB17NAC35-4 Measurements!

August 21, 2016 Posted by gornir


 

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.

For details see:

Kensho Two – M2

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
