[QUOTE="Peter Morris, post: 206032, member: 652"] I think 600 Hz is getting a bit low for that driver on the HF950 horn ... The HF950 has a cut off frequency of 400Hz and you are getting close. I do not have any figures on the acoustic impedance of the horn, but I suspect RCF knows exactly whats appropriate and they cross that driver & horn at 650Hz in the TT5A. The 12NW76 will work but the response is getting a bit too uneven on the sim ... you could try it. [ATTACH=JSON]206033.vB5-nodeid=206033[/ATTACH] [/QUOTE]
