Hello Bert,

what is your actual advice for diy basscorrection for my BD15/oris150/diy BD supplied matrix box. Is that the reckmann s1 or, as I saw in one of your recent posts, the Hypex dsp plate amp?
And would you leave the power supply of that plate amp as it is or change it to a linear one?

Second question. I have a mahogany 38 cm tractrix horn as mid/high, beautifull piece really, bought it in France 20 years ago. For reasons of domestic pressure/waf related arguments I caNot change that horn (at present) for an Orphean. I use as driver either an old RCF681 (1 inch) or Altec Lansing 291 (with new diaphragms from Great Plains Audio) 1,5 inch driver. The latter with an adaptor.
My horn has an 1 inch connection but I would like to use your modified 2 inch drivers with it. Could I shorten my wooden horn till the throat is 2 inch or is this not only domestically dangerous but also audio-stupidity?

best regards,

Leo
