And no, I am not talking about the OA series which gave the swedish company Sonab their claim to fame a few decades ago...
One of my clients gifted me a pair of Sonab branded column speakers that I just had a chance to listen to, explore and measure for our own indulgence!
Unfortunately one of the drivers is pretty damaged - I originally thought it would be just cosmetic, but no - and the one speaker in good condition didn't match the expectation from the brand.
I trawled the web in search of a similar product, and it might well be an Australian design, made in the Far-East (which is not that far from Australia after all...) but I can't be sure, so I will not name the potential culprit!
First listening impressions on the "Good Book" by Louis Armstrong are that Louis has lost 20kgs and can't get his voice to come from his belly and the trumpet and drums sound like if we had a bad metal dome tweeter with too much level. So that was the end of my listening session on these speakers, as I quickly reconnected the Microphases and all was back in normal heaven.
But being curious by nature and nerdy by trade, I could not resist taking the stockings off the cabinets and reveal the inside story. Here are some pics that will tell you more than a long discourse:
So far, so good, I hear you say: nice Scandinavian looking tweeter, slightly damaged dust cap, 2-way bass reflex
Well, don't assume anything just yet and let's enter the beast's cavern...
So, I decided to get the AudioTools gear out of the cupboard and my fears were confirmed
Maybe it is worth spending a few bucks on a couple of resistors and replace the defective boomer (19.50$...), as I can find it at my newly discovered supplier, Wagner Electronic Services, in business for almost 30 years and just a few kms up the road from where I live.
I have bought a new woofer and will endeavour to change it and fine tune the filter soon. I will keep you posted!
