  1. Added a follow up video to my previous comparison between the K-10 and CVR 3002. More subs, higher power and load.
  2. This is amazing, thanks Josh. Looks like I can open mine up to go a bit lower than what I had been doing previously. Thank you!
  3. No stress, I can dig through it again. I did play around again a bit over the last week and I think to my ears at least I still like 100 to 110 hz crossover for most music styles. If I drop it down to 80-90 I think it sounds a bit better for stricktly bass music, but for house and techno, rock etc I prefer it a bit higher. Then again its harder hearing it proper indoors. Depending on our pandemic situation when summer rolls around I'm pretty keen on heading out to crown land for a number of days just to work on tuning.
  4. Yeah someone really needs to do some proper bench testing for sure. I guess they beefed up this model already, the 3302 has more power apparently

  6. added some info in the Luke's amplifier test thread
  7. Thanks SME. I'm just editing a follow up to the previous video. This time I was able to run the cvr up to 48 volts driving 4x 21sw152 at a 2 ohm load. No appreciable difference between it and the k10. I have no illusions that the cvr can hang with the k10 all the way to max power, but it can drive 4 21's on a 2 ohm load to pretty fun levels very well. Ill post the vid when its ready
  8. I have no experience with the sinbosen sorry.
  9. Hey guys. While not as rigorous as the excellent testing in this thread I put together a little vid doing some light testing and listening comparisons between the chinese CVR branded 3002 amplifier up against a Powersoft K-10. Might be a good option for people looking for some decent performance at a good price point. Maybe you will find it interesting. Ill have this set up for a couple more days so if you're quick and send me a request for ideas for further testing I can try to accommodate
  10. Hey Josh. Curious if you would be willing to make a recommendation for high and low pass filters with recommended slopes your Skram design. It’s been a while since I’ve had mine out with the pandemic and all, but I’m planning a day at our studio tomorrow to get everything plugged in and spend some timing tuning and tweaking. Planning to get the measurement mic out and spend some time dialing in the system so I don’t get rusty haha. I’ve been happy with the setting I’ve been running which I don’t remember off hand but I’ve got some different amps on hand so willing to try some new things. Anoth
  11. Bummer about the drive man, that sucks. got any deployment pictures from the playa?
  12. I've decided to order one of the cvr d-3002's to see whats up with them. I don't have the equipment to bench test but I can do some a/b listening tests vs my K10. Ill report back
  13. Thank you for clarifying that for me, I will keep on doing what I am doing. SME, thanks again for your input. Phase alignment has been one of the biggest rabbit holes I've fought with over the last few years but I feel I've finally got a reasonably repeatable process that is giving me good results. peniku8, yeah I know know its not ideal but with this covid thing im trying not rack up too much dept for new sound gear. If/when things get back to normal Ill figure out something proper. I dont let anyone touch my gear so not worried about the random factor playing in.
  14. Thank you. Yeah the possibility of one amp having more latency than the other has crossed my mind. They are both non dsp units. Ill need to get a mic on them and do some testing to confirm. On that note, I'm having trouble coming up with an answer reading through others posts. When using REW in the info I have gained from the tutorials it sounds like an external sound card is NOT required to use the acoustical timing reference functions for measuring for phase alignment. I have however came across a user who says an external sound card is absolutely required. I was messing around with my l
  15. I'm actually heading to our local makerspace woodshop this weekend to cut up panels for another 4 of these. I gave a couple of my music nerdy friends a demo and they immediately asked me to build pairs for them. For less than 1k Canadian you can build a pair with a berry nu3k included in the price. Unreal value for the dollar.
  16. I used the 31hz slot design configuration. If I stuff one side of the vent closed it tunes to 22hz. In my experimenting I much preferred leaving both ports open. There is still usable output down to about 27ish hz.
  17. And thanks for sharing your experience with your amplifier. Its not that I doubt that these amplifiers cant be good, there are many examples of first rate quality goods coming out of china.
  18. Yeah thats the thing I guess. I've got a berry nu3k in my living room and that doesn't really stress me out as if it piles up it only effects me, different story when your in the woods with 500 people haha.
  19. Hmm, I had assumed that using different brand amplifiers on the same subs wouldn't be the best idea, but perhaps its not as bad as I had figured. That had crossed my mind but considering my location in Canada shipping to and from the US is stupid expensive and probably wouldnt make it worth it. But I think I will throw it out there just in case. Secondly, yes I had seen a few people mention they run their powersoft amps like this but to me it seems risky to me. Considering I need to rely on my amps sometimes for 3 days straight I would rather run them in more conservative way
  20. Happy summer everyone. Ive got myself stuck in an awkward dilemma looking for a solution. I originally built 4 Skrams using 21sw152 4 ohm drivers and was lucky to come across a right place at the right time deal on a powersoft k10 which has been kicking ass on these subs over the last couple seasons. This last fall I knocked off another pair of Skrams to add some more headroom and give me more flexible deployment options. The K-10 was already maxed out on a 2 ohms load for the original 4- 21's so in the interim I've driven the additional pair with a prolite 7.5, not ideal I know. I'm looking
  21. Thought I should update this thread as I went ahead and built a pair of VBSS subs to live with my Danleys. The hype is real, these are fantastic sounding subs considering their inexpensive cost to build. They wont crack the stucco on my ceiling like the Skrams did, but for listening to music at moderately loud listening levels I couldn't have wished for a better outcome. Thanks for the help everyone, the project was a success! And I didn't blow a bunch of money I didn't need to spend in these strange times. Aesthetically I think they make for a great match with the Danley's as well.
  22. I got an email back from DIYSG. The custom driver coming with their soon to be released 18" kits is based on this driver, but modified in some ways custom for their application. To early to tell as we don't know what changes were made, but what do you think about this driver as a starting point? https://qcomponents.ca/Eminence-KAPPA-PRO-18LF-8.html Based on the evolution of their offerings, the mbm-12 and 15, I imagine the 18 should be pretty similar to the vbss just with a better driver. From what I can tell the same guy has developed all of them.
  23. Yeah I noticed that as well, usable may be around 11mm. Seems to be pretty decent and capable driver for what it is. The price is just insane. A guy could likely build 10 cabs for about 2000 my dollars.
  24. Yeah the more I dig into the vbss it looks better and better. It will be more cabs and more space but they are just silly cheap to build, 4 cabs would run me about 850 bucks Canadian. I'm sure my wife would be fine with a row of 18's in the living room haha! Still going to see what diysg has cooking with their new 18 cab when they add it to the website sometime this week. Its going to be more money but will have better drivers for sure. He said the kit its going to cost just slightly more than the 15 as the driver has a ceramic magnet vs the neo in the 15. A pair landed in Canada should be
