ScanSpeak D2905/950000 Measurements!

October 21, 2014 Posted by gornir

D2905-9500_2D2905-9500_1

I’ve measured and tested the very nice “Classic” ScanSpeak D2905/950000 soft dome tweeter. It has a very robust and nice build quality. The price tag is rather high, but this tweeter is well worth the money.

Wharfedale Diamond 10.2 review part 2 Update!

June 8, 2014 Posted by gornir

 

 

I described in part 2 of my Wharfedale 10.2 review that my right loudspeaker didn’t sound and measure the same as the left loudspeaker.

The reason for this is:

  1. The mid-woofer had a mechanical creaky sound from the surround/suspension and even though it measured almost identical as the mid-woofer in the left loudspeaker the creaky sound could be heard in bass heavy recordings.
  2. The tweeter in the right loudspeaker had significant lower sensitivity which gave about 1.5-2dB lower output in the tweeter’s frequency response.

 

I contacted my local HiFi shop and supplier which immediately supplied me a new tweeter and mid-woofer.

I have now updated the part 2 review with some new measurements for the replacement drivers.

Wharfedale Diamond 10.2 Review!

May 11, 2014 Posted by gornir

 

 

In a series of articles I will review the popular budget priced stand-mount loudspeaker Wharfedale Diamond 10.2. The Diamond 10.2 along with its smaller sibling Diamond 10.1 has got some good reviews among the Hifi Magazines around the world.

The Diamond 10.2 costs approximately 450$ and has roughly the same price as an entry level DIY loudspeaker of decent quality. In this article I will try to reveal some of the tradeoffs made in order to manufacture a loudspeaker in this price range compared to a DIY loudspeaker.  I will also explore the possibility to make some modifications to the original Diamond 10.2 design in order to make it sound better.

Unlike most Hifi Magazines who only review the loudspeaker and give it some subjective listening comments and sometimes some rudimentary measurements descriptions I will do the following:

First I will unpack the loudspeaker and describe what’s in the “package” and describe its build quality and chosen components. I will listen to the loudspeaker and give my subjective comments about the sound quality.

Then I will do a full set of measurements including on and off-axis frequency measurements, impedance and distortion measurements. I will comment my findings from the measurement results.

After that I will dissect the loudspeaker and un-mount the drivers, cross-over, ports  damping material and examine the cabinet construction in detail. I will measure each individual drivers frequency, impedance, distortion and analyze the cross-over etc.

Then I will do some cross-over simulation of the original cross-over and see if there are some possible improvements to be made to the original cross-over or if a complete remake of the cross-over is necessary. I will also make some suggestions on how to modify the original loudspeaker regarding cross-over component quality, cabinet damping and bracing etc.

Finally I will do a full set of new measurements of the (perhaps) modified loudspeaker along with new subjective listening impressions.

 

I hope you will enjoy this article series!

Satori Two – Monitor Construction Released!

January 3, 2014 Posted by gornir

It´s time to publish the first AudioExcite loudspeaker design this year!

To the left in the above picture we have the new Satori Two – Monitor besides the “Sequence Three – Grand Reference” loudspeaker.

The Satori Two – Monitor is a large sized stand-mount loudspeaker and is based around the SB Acoustics Satori mid-woofer.

The Satori mid-woofer is a well behaved very nice sounding driver that sets a new standard for high-end drivers in its size. The 6.5” mid-woofer size fills a gap where it’s hard to find equivalent drivers today.

Either they are larger 7” mid-woofers, which are great in the bass department, but often lacks mid-range refinement and need to be crossed over below 2kHz. Or they are smaller 5-5.5” mid-woofers that are great in the mid-range, but struggles in the low bass department.

The Satori driver fills that gap with honor!

First, I planned to release the Satori Two – Monitor with two different tweeter options, the ScanSpeak R3004/602010 and the D3004/602010, but in the end the “D” version blended more nicely with the Satori mid-woofer and was sonically better than the “R” version.

That doesn’t mean that the “R” version tweeter isn’t any good, but it simply isn’t good enough in this configuration.

A comparison between the two tweeters can be found here: ScanSpeak Illuminator Tweeter Measurements!

For the Satori Two – Monitor construction details see: Satori Two – Monitor

 

Later this spring, I will build a pair of nice looking matching front covers for them!
