Hello! I don’t really have a problem, but I’m already thinking about what I could do next. Right now I have the SPL Dynamics 6.2 on a Concord ST50 (which will soon be replaced by Zimme’s Kicx VX300). So I think the front section is enough for me, power amplifier and front system are both just just bought, since there is no money left for spending. But the subdepartment is already expandable in my opinion, Atomic Manhattan 12D4 on Macrom M 2A.500d. I think the subwoofer would have even more potential, is currently in such 55-60Liter BR. The final stage is probably pretty close to its limit, runs eigtl also quite well together, does not want to scrape the sub. So what do you think, could I change something relatively simply? With little money of course as possible My dream would be a DD 9915 best in bandpass, but I would need a completely different level before and even more power and stuff. Ohso, Strom… mm2 cables from the battery to the cap and from there with a short (<30cm) 20mm2 cable to the power stages. Should that be enough, mass amplification on the battery I have also. So what could you do? Can you also build Manhattan in bandpass? I look after already months now, but have nowhere found a housing proposal and I can't calculate it myself... If you couldn't expand my system with little money, everything just remains like this, if then ma l n bitl money is there then equal subwoofer and final stage is replaced at once! If you think of anything you can write it! =)
