" End of last year, Bob got out from TA and started his own brand, IMR Acoustics.
Now before moving on, some of y’all may have heard about the complicated situations now going on with Trinity Audio. For those who do not know, I rather suggest you to search up what is going on with them, because it’s going to get way too lengthy to explain. Anyway, Bob have clarified that IMR Acoustics is clearly a distinctive brand departed from Trinity Audio, so I won’t be relating IMR much to TA here."
