  1. Got some advice today to go with a mono-chamber around 5.5 ft^3 net, 60 in^2 of port tuned to 27 Hz. Does anyone have any experience with these subs & can chime in? Worste-case i'll block the ports & run these sealed.
  2. Not sure if anyone can pitch in on this but according to this page: https://reaudio.com/products/woofers_xxx.php The recommended enclosure is around 4.816 ft^3 net, 6.0 ft^3 gross, tuned to 27.5 Hz, 20 inch^2 of port, 10" long. In numerous posts/forums around the net I'm seeing people saying the recommended specs or the specs they are using are considerably larger than this. Is this a legitimate spec for two of these 15s & is it reasonable to go with this VS a much larger alternative? I have around 7.8 ft^3 gross available in my vehicle. Using around 5000wrms. Looking for output down to my subsonic @ 25Hz & a roll off after 40 Hz. If I can obtain more of my output between 28-36 Hz would be ideal. Doesn't necessarily have to be a large peak, prefer more of a flatter response. Any assistance would be greatly appreciated, thanks.
  3. Nice figures O_o Thanks for sharing bro. Having a strong preference towards the Nsv4 15. Just hoping it's the best bet out of the current options. Was told it'll take 2 months to get it from the day I place my order. Quite the wait unfortunately. This is due to the fact that I have to order a black spider kit & also considering a carbon fiber dust cap with a black Sundown logo.
  4. Still having issues making a decision. Any input would help from anyone having experience with the mentioned subs. The FS on the 12s are mid 30s & looking to play down to 28 comfortably. Am I paying too much attention to the FS ratings? This also bothered me about the Nsv4 15 as it was still low to mid 30s with the softer black spider pack. The Xv2 15 & Zv5 15 are 28 & 29 FS. Options right now are Zv5 15, Nsv4 15, DB-SA415/418. Deaf Bonce Apocalypse AAK-5500.1. Thoughts? Thanks!
  5. Hopefully it's just the enclosure & nothing else O_o
  6. Luvvin it bro! Keep making that progress!
  7. In most cases, yes it would definitely be worth it. If space for the enclosure isn't an issue, two 12s to two 15s is a significant jump in cone area & should result in a nice increase in output. That answer is just scratching the surface to get the ball rolling though. There are other factors to consider.
  8. Got my Deaf Bonce DB-SA412 sold finally. Just want to make sure I'm making the right decision so open to other suggestions. Anything I should strongly consider over the Sundown Nightshade v4 15?
  9. Didn't take it that way & I understand where you are coming from which is why I thanked you. Know you were just looking out. No apology necessary bro. I agree, a lot of people have that misconception. It was explained well in the video using the dog food. Lol
  10. Thanks bro. I'm familiar with t-lines. I've designed & built a couple as well as helped design others that were successfully built. My last Sundown Xv2 15 was in a T-line & I enjoyed it thoroughly. I've also seen that video quite a few times in the past. Appreciate the advice & info. I jumped to 8:29 just to see what you were referring to & I am aware of those facts. I enjoy flat response as well as higher levels of output. I know a 15" t-line isn't a common situation due to the enclosure size & it being a lot more common to use smaller drivers with that particular enclosure design, but that doesn't say it's a mis-match O_o. It's just different. Thanks for looking out though
  11. Was thinking that the two 12s would move more air than the single 15, that's why I was considering them. The 12s cost more, larger ported enclosure, 4x the weight of the 15 & the enclosure type I want to use, can't fit with 12s. Was supposed to put in the order for the Nsv4 15 today but had to hold due to the Corona situation (My mind can still change to 12s. Keeping open on matter). Spending that much on a sub right now would be a bit irresponsible. It's just starting to pick up where I'm from. Can't wait til things settle down to get the process rolling again. Getting the softer spider pack. Not sure if carbon fiber dust cap is worth it as I'll possibly be invert mounting. Running on a Deaf Bonce Apocalypse AAK5500.1. It's going in a transmission line tuned to 32. Thoughts?
  12. Hmm, is that confirmed bro? Didn't hear/see anything O_o Was being allowed to place an order from my local dealer. Wondering if I should hold or go ahead, especially with the corona situation. Btw, how's the NSv4 18 going? Do you have any links to vids? = )
  13. Can anyone chime in with regards to 2x Zv5 12s compared to a single Nsv4 15? (with the non-spl kit)
  14. Not going to get near the recommended volume in a comfortable manner. Tried fitting volume everywhere I could think of & it was still too small. Considering just waiting til NsV4 15s come back in stock & take one. Won't move more air than the two Xv2 15s but it should do well for a single 15. Apart from that, my other option was two Zv5 12s.
