Wow, first post ever in this forum. I'm humbled!
Is there anyone out there with a TM112 who can give me a description of the venting employed by H&K? It could be a properly designed reflex port tuned to the cabinet volume and driver resonance, or it could just be " 's a vent mate, 's an 'ole in the box", (or the equivalent in German cockney!) It uses a Celestion Vintage 30 but this driver is usually not considered best suited to port loading, it usually performs best in a plain sealed or open back cab. So is the "vent" just an opening to the outside air, or is it a properly loaded reflex port which bolsters and extends bass response? And can you estimate the approximate dimensions of either the port or the 'ole?
The TM212 is described the same way, as vented. I'll post a query there too in the hope of catching a few more users.
