SR551-HDS -- 2-way standmount

[gornir]

I have now finished the design and it’s renamed from the working name SR551-HDS to the “Revelation Two – Monitor”. Since my last post I’ve done additional tweeter damping tuning and finally made the last version of the cross-over after many hours of listening tests.

You can read about the design in detail on my new website:

Summary:

The Revelation Two – Monitor is a medium sized stand-mount loudspeaker using two very high quality loudspeaker driver units from ScanSpeak. The design offers several tuning options in order to satisfy personal preferences and sound characteristics.

At a price of 1000-1200 US$ a pair it’s not exactly a cheap DIY design, but the sound and performance delivered from this loudspeaker usually costs several times more on the commercial market.

Sound description:

It is very hard to describe how a loudspeaker sounds like since it always will be a subjectively opinion, but here is my perception of the sound.

Despite the name “Monitor” the Revelation Two – Monitor isn’t a “Studio Monitor” used for near-field listening, but it brings out the details from recordings just like a “Studio Monitor” and it do so without ever sounding analytical cold, harsh or edgy.

The loudspeaker sounds bigger than its size indicates and it has a nice low end extension which reaches to the low 30:ies when room gain is added. The mid-range is wonderful natural and has an open character that doesn’t sound compressed or hard even on less good recordings. The tweeter is soft sounding with a nice vivid presentation and top-end sparkle.

When playing a well-made recording the loudspeaker really shines up and presents you with a very nice 3D perspective with a generous width, height and depth.

I have several designs on the workbench at the moment and I will soon start a new build thread.

That tweeter is nice I think, using it myself.

Hi everyone,

I have updated the Revelation Two – Monitor design with distortion measurements of the finished loudspeaker.

The measurements confirm what you hear!

All distortion harmonics are low in the critical 1-3kHz frequency range. All odd-order distortion is low below 1kHz, while the harmless 2nd order distortion is a bit elevated between 300-1000Hz. The lower treble distortion is also kept low.

I have also updated the driver unit measurements section with distortion measurements for the ScanSpeak mid-woofer 15W/4531G00 and the tweeter D2608/913000.

For details see:
