  1. All of the outdoor measurements with the Ipal's are posted on the main data bass page for the Skhorn. Have a look at the voltage sensitivity measurements. There is no processing on those and they are outdoors. Really doesn't need a lot of processing. Throw a 25Hz HPF on there and set the LPF where it matches well with the mains. They run pretty decent up till above 140Hz and the response is reasonably flat, so anything below that should be fine. The rest sorta depends on the mains, amps, environment and bass content ( limiting, etc...)
  2. Hey Chris. The Nero will make some noise but it has lower xmax, power handling and less motor force. It probably wants a bit more cabinet volume. Hard to say with out trying it though. The Mms is light too indicating a cone that may flex at war volume. CKram should be useful up to 120Hz giver or take.
  3. That's my bad PC. My inbox was full. I've cleared out some space. It should work now.
  4. I think you need a minimum of 5 posts. I haven't been on AVS in months.
  5. Yes I was factoring that in as well.
  6. In my experience the NLW9601 drivers are a little less capable than the B&C's. If you can deal with the impedance the Lavoce drivers are about the best option I know of for reasonable money.
  7. Is this an outdoor measurement? How far away is the nearest large object? Building, truck, etc? Looks like about 8db down at 30Hz compared to 100Hz. The tuning seems to be a bit under 30Hz as well. I'd expect about 4 or maybe 5dB down at tuning with those drivers. The HPF probably shaves another 1db off. Realistically this isn't too far off. Once all of the factors such as driver tolerances, construction methods, signal chain, measurement setup and atmospheric conditions are stacked up it can account for quite a bit of variation. I'd not worry about it too much if it's a little different from the model or other peoples measurements. Is the mic equidistant between the vents and the upper section or closer to one vs the other? That could account for another 1dB.
  8. I'm not aware of any. All of the neo motor woofers have gone way up in price and the availability is hit and miss. You could try a DS115 or a Lavice driver but these face the same problems. I'm not as on top of the market as I used to be so perhaps there are some newer options to look at that someone else knows of?
  9. Hello Alexlel. Thanks for the info. Interesting. A 4th order LR would be 6db down at the Xo frequency. 109Hz. The response should be slightly rising towards 120Hz with that driver without any processing at all. That's including increasing directivity/baffle step as the frequency rises. You also have a pair of cabs. I wouldn't be surprised to see the response up 4dB or so at 100Hz under these conditions. Either way that's a useful starting point with just a LPF and HPF. Lowering the LPF frequency and/or changing the slope or filter type should be able to get your XO to the mains where you want it without much extra EQ needed.
  10. Make a few posts and message me your email.
  11. I would run the Skram or Ckram sub which is smaller, instead. Splitting the Skhorn in half results in a lot of driver pressure directed into an outer panel which I'm not a fan of. It really wasn't designed to be split in half because the driver arrangement is less than ideal for that.
  12. Cone flex can be a problem but only in drivers not designed adequately for high pressure applications. It has not been a problem with any of the cab designs I've made/tested/used with 18" or larger drivers. There is a reason that modern high power sub drivers have a heavy mms and stiff suspensions. It is required for strength, control and power handling. The cone on a larger diameter driver must be stronger / thicker than a smaller diameter unit, the voice coils are massive to handle large power inputs, the suspensions are stiffer and heavier to keep things centered and prevent overshoot, fight against gravity over time, etc. Most pro audio and car audio subs are built to take a lot of abuse. This is why a pro audio 15" woofer might have a MMS of 80g but a true subwoofer might have an mms >250g. Even though the 2 might have a similar FS and Xmax rating or even power handling, they are still suited to different jobs. The 80g 15" woofer is not going to fare as well in a FLH or other high output high pressure loading.
  13. Yeah it's nice to have options and this should slot right in there with the NSW and Ipal at the top of the heap but unfortunately prices for everything have gone crazy. NSW's used to be available for $650-700.
  14. I do like 240v for running big / multiple amps. Just seems to do a better job in most cases. Speaker gasket tape FTW! I use that for the hatches, handles, drivers, etc...Always good to have on hand.
