Moin! Was earlier at the ACR and bought distance rings for my Canton CS2.16. Originally I had to get a Ground Zero TB 300BR (139€), in addition a GZ 4200X (199€) Now I asked on the occasion directly if one can get me these things. Yes one could, but then they told me that the Eyebrid Y4Y450 should be quite decent for 199€. In addition an Eyebrid Y12.1BB for 149€. Interesting is that the Eyebrid ES has two power supplies and 2x50W and 2x100W. Man also told me that if you break the 2x100W in a test 350W RMS come out. Sound quite tasty. But then they also wanted to tell me that Eyebrid Ground Zero from the low budget segment sold. I didn’t really want to believe that, I read a brochure and went home. I went into the inet and browse. But I’m not much further away, the ACR guy had the typical ACR function, the own stuff. Now I would like to get the confirmation. e both Eyebrid things should be a total of 10€ more expensive and then better than the two GZ???? Unbelievable I find. What do you think about it? Maybe you have other suggestions? Anyway I need a new power amplifier + 12″ sub incl. BR housing. Power amplifier max. 200€ and sub max. 150€. Because if the suggestions cost more, I resort to my GZ solution and GZ is really not from bad parents. thank you already!
