Meridian Unplugged - Powered by MrTechGuy.co.uk Forums Thread Like Summary - Firmware update DSP5200 Legacy

Hello,

I'm new into DSP Meridian. My first encounter with Meridian was when I started to work for the Danish importer of Meridian. That was the period were the MCD 100 and 100pro, M10, M20 and M30 were hitting the market. Very impressed with the M10 and M30 but find them difficult to find 2nd hand and if they pop up the tweeters seem to be an issue.

I am interested in a set DSP5200 legacy (budget reasons) I wonder how they compare to M20? Anyone who can chip in?

I'm looking into the 3-4 different version I wish to know if the Legacys firmware can be upgrade so a version with apodising filter (version 2.xx ?) and fine tuned crossover will work.

One set of 5200 has version 1.2 or rather the seller tells he never upgraded them.

I would like to ask if I can upgrade them myself? I found the configuration software but not the different firmware version. Can the gents in here help me out with a solution?

Thanks in advance. Regards Mikael

Firmware is not part of it, sadly i cant find my copy (its been many years and a few computers ago). Not sure about how the sound was changed... was one of the first thing I did with mine.

Replacing the ferro fluid, is honestly not bad. Another member Stu has a video and some posts HERE . was able to get the job done on mine much very quick, 15min (on the second, 1st one took longer). Instant improvement. Do not think the the SE tweeter sound right, beryllium tweeters have radically different electrical and mechanical properties. lots of posts about the tweeters, people replaced them with various results, in the end the DSP crossover and adjustments are for the current tweeter. After repairing mine, lost interest in upgrading or modifying the tweeters(they sounded great, did email Seas ~the h1212 is a close fit). discontinued SE and .2 upgrade kits(new DSP and amps?) are not available any more last i looked.

5200's come in a few versions. Legacy is typically non speaker link with a final firmware revision of v1.4. SL versions came in .1 and .2 (2.63?), along with the highly praised SE (3.14).

Updating firmware is a fairly straight forward processes; updated my Non SL-5200's and other gear with out issue (1.2 to 1.4).

The firmware update tool is built into mConfig (under file) or download the firmware software from Meridian Site.

The DSP5200's are going on 20 years, aged capacitors and dry tweeters are your biggest barriers to better sound quality: Very good sounding speakers when everything is up to snuff.
