  1. Its under 10 feet. I'm 6 foot, so in total the stack is about 9'ish I would say
  2. Blowing out the cobwebs today
  3. Sorry I didn't specifically take not of that, but I am going to play around with them again tomorrow so Ill try to get a sense for you. The fan's are quite noisy, to use in a theatre or listening room you would have to look at fan mods for sure.
  4. Yeah its more like the opposite in this case. If the box resonates a lot, it will add its own sounds to musical output, which is not ideal. There are box designs out there that use thinner wood and extra bracing, so to an extent perhaps you could get away with it up to a point. If you are planning to use the recommended driver at the maximum powers the box will have a lot of energy in it, so good bracing is really important
  5. I wouldn't go for a lightweight plywood like that for a design like this. Think of the cabinet like a musical instrument, the stiffness and density of the cabinet will contribute to the sound in many ways. If the cabinet can vibrate and resonate with the driver movement it will color the sound coming from it and you may not be happy with the outcome. If you can't do baltic birch you could get away with mdf as it quite solid and dense, its pretty heavy though.
  6. Added a follow up video to my previous comparison between the K-10 and CVR 3002. More subs, higher power and load.
  7. 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!
  8. 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.
  9. 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
  10. https://www.facebook.com/CVRAUDIO
  11. added some info in the Luke's amplifier test thread
  12. 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
  13. I have no experience with the sinbosen sorry.
  14. 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
  15. 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
  16. Bummer about the drive man, that sucks. got any deployment pictures from the playa?
  17. 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
  18. 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.
  19. 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
  20. 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.
  21. 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.
  22. 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.
  23. 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.
  24. 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
