  1. I can see a 'reaction' button on status updates, but I dont see a 'reaction' button in any normal thread posts...  Are yall able to see this mythical button on normal thread posts?

      Thanks Antheny.  That fixed it.  Hopefully yall can get that bug fixed soon so I can still be incognito at work.  This theme is very bright haha.

      Go ahead and switch it back to SMD Classic. It should be better now!

  2. Bought an AMM-1 from Triticum. Good price, shipped quick, arrived on time. Item was packaged properly and arrived in good condition. 10/10, would buy from him again. Thanks @Triticum Agricolam!
  3. The heat at Heatwave was beyond oppressive. Good show, though. 

  4. WinISD Pro (alpha) or Beta?  Im hoping on some advice from experienced users.

    I used Pro the last few days.  I modeled my built system, and the impedance plot and cone excursion seem to match the model well.  To me, seems like the software fkn nailed it.

    If using Pro, are there any nuances to watch for?  Or is it a safer bet to stick with Beta?

    TermPro was off by 7dB on the same design.

      Definitely stick with the pro version. As a note, I wouldn't suggest using the SPL graph to try and see what the SPL of the enclosure will be like in your car or room. It will more than likely be very off. Use it more to get a feeling of what the response will be. Can also use the transfer magnitude graph for that. If modeling a ported box, I would suggest looking at the rear port air velocity. In general I would suggest reading their help page on how to properly/accurately enter in custom driver parameters. It can be a bit temperamental in that sense.

      Shit meant 7 Hz, not dB. Anyway, thanks for the reply man. 

  5. I guess Boto Fuckit finally shit the bed for good this time. 

  6. Let's say you have one battery resting at 12.0V and the other batts resting at 12.8V. If the charger doesnt see that 12.0V battery, it wont recover properly. Your system voltage will be an average of all the batteries (let's say 12.5V for sake of convo), so running recovery on a whole bank wont allow the charger to see the 12.0V battery. Now if all your batts are dead, thats another story. Are you trying to recover because you have low voltage? I would disconnect each one and test resting voltage with a DMM.
  7. If all your batteries dont need recovery, then i wouldnt run the whole bank like that since the current will be divied up between alll the batteries. Others may have had success doing this, but i'm with Karkov, i would do them separately. How many batts do you have and what group are they? Also, why do you think you need to recover them? Keep in mind the PSC15 is a rather small charger.
  8. I've recently been enlightened to this notion as I push my amp to its limits and get stinky coils all too often. Its good to see this topic enter discussion. Time for a bigger amp!
  9. Designed my ported box in TermLab.  Calculation and measurement while I built the box is telling me I'm tuned to 33Hz.  Used an IM-SG to confirm box tuning is actually 26Hz.  Perceptively, I thought 33Hz really was the tuning frequency, but I was mistaking it for the onset of cabin gain (Starting around 32Hz and dropping around 48Hz).  

    Lesson learned: calculations are approximations, and tuning frequency of a box is hard to discern by ear once its in the car.  Max port velocity and minimum excursion is what I should have been paying more attention to. 

  10. Nice build log and nice box, man. I got hooked when I saw the 6th order. How does it play? Are there any design features you'd do differently?
  11. Im in Las Vegas for a conference Monday and Tuesday. Never been here before, but unfortunately im only here for two days. That being said, whats YOUR favorite thing to do in Vegas?

      Check out Absinthe and thank me later. You are in the prime area on the Strip. You're within walking distance to a lot. Get a cab or bus ride to downtown Vegas at night.

      Just checked...Absinthe doesn't run on Monday or Tuesday..noooooo!!! In that case....there is bomb ass food all over Vegas. Go get a good meal and then go hit downtown. There is some new shops and stuff across from Caesar's at the Linq as well.

      wow really fuck off then, lol

  12. Have you confirmed DC resistance of all the speakers wired together at the amp (what the amp sees)?
  13. The D3100 and D3400 are the same overall width (6.81 vs 6.75, respectively... lets call it 6+7/8 bc busbar) Heres the D3400 under the hood showing the two values that were posted earlier: Heres my D3100 in the back thats actually on a bus: Heres the post-to-post distance: Hope that helps man! I know how it is getting ahead before parts come. Makes the install much quicker once the critical components arrive.
  14. Short side 1+3/16 long side 5+11/16 total width 6+7/8 hole to hole of two parallel mounted batteries: 6+7/8 I bet you'll notice once you start working with it.
  15. Right. So the short edge-to-post dimension on the first battery plus the long edge-to-post dimension on the sefond battery is the same total distance as the width of the single battery. So your post to post hole spacing equals the individual battery width
  16. Was about to measure the distance for you to determine hole to hole spacing, but realized its just the width of the battery. Anyways, the short side is 1+3/16". Ill post a pic later since file size is too big to post direct.
  17. Hey man, Ill let you know when i get home in an hour or so.
  18. Tribe, you posted about an SCV-7500 a few weeks back, right? Are you still going to run that amp? Skippy mentioned (2) 10s.
  19. It depends on what frequencies youre sending to each speaker. You can either use the amp's crossovers or setup external passive crossovers to split the frequencies to each speaker appropriately. Or use a DSP. Although, I dont see the point in sending the same frequency bands to two different speaker sizes.
  20. I dont think you'd need a 4ch tweeter amp with only 4 tweeters. If you went two pair of 4ohm tweets per channel (each pair wired together in parallel, so only 2 channels being used), you could wire the channels down to 2 ohm each. But then you'd have two more channels unused in that config with the 4ch amp. If you need a tweeter amp just get a small 2ch amp. Most tweets are 4ohm or higher, so just wire each set in parallel (left and right). How were you planning to wire all those mids to the 4ch?
