Older Markbass cabs.... HQ line - anyone know anything?

Hello

I've been offered a local trade for a Markbass STD 103 HQ cab, older silver markbass logo, no orange on the cones.

Using the search facility on here I gleaned this from an old thread from 2003...

MarkBass 103HQ Standard
::TECH DETAILS
Impedance 6 Ohms
Power Handling 600W RMS (AES Standard)
Crossover frequency 2.5 Khz
Weight 26 Kg
Height 610 mm.
Width 586 mm.
Depth 478 mm.
B & C Custom Neodimium Woofers
Two 1/4'' Jack + one neutrik
Variable tweeter level control situated on the left side
Professional handles
18mm high quality multilayer poplar
Metal corners
38 mm Rubber Foots
High Quality crossover
Black Felt covering
One B&C compression driver with custom horn ​

so my next question is given the specs mean very little in practice - is there anybody here who has a clue what the thing might actually sound like? Anyone used these older "HQ" range of markbass stuff?

 

I'm thinking this is older than when Markbass stuff got over the atlantic and onto talkbass' collective radar....
