Some time ago I upgraded my system because of space consumption and over-dimension. 3 power amplifiers have moved to a Xetec 5G900. In order to still have power reserves for the sub, I wanted to exchange my HX300 S4 for a D4. Quickly the S4 was sold and the D4 bought. Unfortunately the seller never sent it and refunded me my money back At that time I had built a housing for the old Hertz according to construction proposal. 32l net from 22mm MDF, 88mm tube with 200mm length. I could have reinstalled the new D4 Hertz 1:1, because at least in the theory (bass cad) nothing would have changed to the negative. So far so good. The case is over. Only the sub is missing now. I thought if I did not take a completely different one than the HX300. What would you take then? In the very first line the sub should sound and not press. Just because I don’t need the blunt pressure anymore, I have equipped housing should be as small as possible. But the 32l were already fine. Depth should be present, but need not be brutally deep. My old HX was tuned with the case to 43hz, was enough, because I rarely hear hip hop or something like that anyway. Rather trance, dance, Prodigy, scooter, sensation White Krams etc. but also things like Depeche Mode, REM or 80s Partymukke, Boney M. Whether it is 10″ or 12″ does not matter, but should already remain in the range of the Hertz from the skills. So a 10″ with less depth than the H ertz = build suboptimal housing itself is no problem, but also with housing. Priced up to 250€, if there is one that I absolutely have to have and which costs 270, also worms. But certainly less. Good used or new is no matter, but rather used at the price limit I think. What about Atomic? Manhattan or Quantum? I have already seen Manhattan used for 120, unfortunately S4 Ohm. If it is not possible at all, I also take S4. That’s where the Xet comes in. ec also still enough, my old Hertz already had it. Or I have already seen a Hollywood Edge. Or just the HX again? Would you like to try something new car is a Golf 4 Limo, Front Eton RS 160, level as said the 5G900. Creative suggestions are cordially invited Thank you.
