Hi, i need some help building a 1x12 bass cabinet, that i want to use stand alone with my Peavey Minimax 500 amp. The amp has 300 Watt at 8 Ohm. (Since i don't play on big stages i think 1x12 should be good enough and the bigger places usually have a PA.) I moved to brasil and here bass cabinets are unbelievably expensive. So i want to build my own, buying the speaker in Germany and taking it in my bag to brasil, when i next come to visit germany. I am thinking about about 50 liters cabinet, but it would be ok up to about 70 liters. I read a lot about it allready and people mainly recommend Eminence mainly. The Basslite S2012 seems nice but has only 150 Watt power handling but only 125 Watt power handling with the low frequencies in a cabinet (says the Eminence Cabinet designer). So i was looking at the Deltalite 2512, which has more power handling but seems like it has just the same as the Basslite in a cabinet. Then there is the Kappalite 3012ho which seems nice, needs to lows to be boosted at the amp a bit, but then could work nicely maybe even stand alone, because of the bigger power handling? What about the Faital Pro 12PR300? Does it compete with the Kappalite for power handling and only has less rising response in the mids? What about Beyma, RCF or Oberton? Which one would you choose and in how many liters cabinet? So what is your recommendations? Or should i rather go 1x15 and use the Faital Pro 15PR400 in 70 liters? Or 2 Basslite S2012 in 70 liters? I think it would be wise to choose a 8 Ohm speaker, or should i go 4 Ohm to get the full 500 Watt? I hope some experts can help me choose. Thanks a lot in advance!!! Ralf P.S.: i am also thinking about getting a cheap used 1x12 cabinet in brasil and change the speaker. Is there any reasons i should not do it? If i know the volume of the cabinet i just need to change the bass reflex port to the right diameter and length, right? Or is there anything else i have to worry about?
