  1. UPDATE! We did some testing couple days ago (video coming out at friday) and we have set our record!! We are currently at 155,35dB 71Hz Here are the measurements: our peak 155,35 was before these tests and it broke one of my prototype amplifier. It was because powersupply had fets from different batches, and it did not like 1ohm impedance (0,25ohm nominal impedance). But the tests here were made at 1ohm nominal impedance -> box rise to 4ohms. Impedance curve suggested that the boxtuning is now at 61Hz and we burped at 71Hz, i hink we should have tried that 60s before just burping the note we tought might me highest. Lesson is learned here, first sweep, and calculate before just burping the s#it out from your amplifier Loudest sofar. And it took us into TOP20-25 in the world (yeah, not measured at competition etc, but hey it is a start). Here is a good milestone to celebrate, but we are far from beign done. Need to have that 160-165 before christmas with low power so we can start chasing that 170+
  2. And this is propably most recent video, where we plug the subs into 4ohm and wallsocket 230V 50Hz (Really dgaf if the subs are seen in the video. We want to make thiskind of videos anyhow, the dust has been settled and new subwoofers will be replacing these when done, so we want to have fun with these neos first)
  3. Update!! We are planning to make Project Zero white. Also next few videos will be in different order in timeline, as i did got no time to edit the videos before Hifi Store Demodays
  4. dick move yes. What can we do about it? Nothing. Just smile and continue, no time to worry about losses, when the journey is just at the beginning. New timelapse video online: Featuring Juuso Heinonen.

  5. Thanks for your words! We have no dB Drag judge in Finland, but the sheet metal we replace is 1/3 of the thickness of the OEM that + welds should keep us under the OEM ridgity. This will be built to SS1-2 no matter what who thinks, we well rebuild whole car or buy another fiat and cut it in half so we can get OEM skin at front it it is DQ'd. What comes to the chinese subwoofer manufacturer... i want to say rude, but it is their loss. You will not see them anymore. I do not want to work with people who threat via whatsapp that "internet can be your friend or kill you".... and that is a quote. My co-operation with the manufacturer is done. He wants no videos public, he gets no videos. All or nothing we do not make things in secret, whole caraudio industry is one big secret family, all loud SPL cars are kept secret. I have been doing car audio for 7 years writing everything i find out public at my webpage www.lisääbassoa.fi and now in videos. EVERYTHING. No secrets from us, ask anything we will answer all we know. Only thing that we do not talk about money because we are in a certain point in our career that we get things cheaper or sponsored and we do not want to mislead people to think that a newbie can get everything as cheap as we who do 200-300 youtube videos / year for the brands we love. whoa, that helped.. so umm. Project continues!!
  6. ** Videos has been removed, because it included information i am not allowed to say in public anymore because reasons unknown to me** ***At this point, all i want to say is that we co-operate with the manufacturer/seller to their benefits and want to be a "good guy", so video will not be back online*** Thanks, and sorry.
  7. Yes, now days you can do the same, in smaller batches. Still i suggest of buying subwoofers from a well known brand just to get warranty. When these break, we need to fix it ourselves, no problem for a enthusiast, but a hobbyist it might be too much!
  8. Thank you for your reply! I really appreciate tech talk as i want to learn more and more. It might be just a marketing think, but we've been told that ********** are the same subwoofers that ours are +-some customizationg tho. Rarely the subs held when burping many times so every recone makes them littlebit different. Also i want to post here on how did we got the subs and contact information on about how you can get one: **removed**

  10. We need those floors done before plywood, so we spent few days mainly under the car to get everything g done.
