  1. Hello Sakkara...Welcome. In my opinion total speaker size/number of cabinets is most important especially in the bass region. Driver quality and synergy with the cabinets is second. Amplifier quality is 3rd. How many cabs to use depends on the room, application and how loud the average playback level is. For any type of live, DJ, dance club type of situation I'd recommend at least 2 Skhorn's or 4 Skram's or Othorn's as a starting point. Double that amount to really get the place rocking.
  2. 9601's are sold...Thanks Paul.
  3. So far the pro sound MFG's haven't been beating down my door to have >$10K flagship subs tested!
  4. I need to hear one of these M-force systems at some point!
  5. I've never tripped a breaker with a K20 or the K10's . I have only used them on 240v with 30A breaker though. Same with the SP2-12000's. That's the AC I have at home, at the rehearsal space and for the outdoor GP testing. I've only hooked a K20 to 120v one time to check dsp settings. Breakers will pass significant current beyond their rating for a few seconds so it takes a ton of long term power to trip a 30A 240v line. Even the SP2-12000 dumped into 2 ohms per channel at clipping with a long sine sweep didn't do it. Perhaps a few sweeps back to back would've done it eventually. Over her
  6. I've heard of them but never seen one over here in the states. They seem to have a pretty good reputation among the live sound guys. Not sure these would drive 8 ipals that well. The specs list a couple of things that stand out. 1.6 ohm 10kw rating per channel has a note about calculated as 2ohm + 20%? I didn't see mention of if the power ratings are with all channels driven or not or the duration or signal type. The big spec that jumped out at me is the long term power limit is 16A, so I don't expect it will do very well in a sustained power test. The K20 and K10 allow for settings of up to 3
  7. Yes they should work great in the Skram's. A pair will be just what the doctor ordered for outdoor parties.
  8. I still have those available.
  9. It is not. It sold a few weeks back.
  10. 3mm or so undersized should work. Depends on how many coats of Duratex though. If coating both surfaces multiple times you may need a bit more.
  11. Do you have any pictures? Would you consider selling without the driver?
  12. It depends. The K20 will run stereo at 2 ohms, but it will limit long bass notes into low impedances considerably. Buss pumping can be a problem. The exact impedance and phase of the load and the bass content used will determine how well it does. I really recommend bridging the K20 or K10. They perform better with heavy duty signals into low impedances when fully bridged.
  13. Awesome. I wish you were closer to me so I could come to one of your events and get a listen of the Skram + SH46 combo.
  14. Hope everything is good with you Luke. Good luck with the sale.
  15. HIL is still in effect. There's no way around it. I probably won't. The limited bandwidth of TH's or the added complications and size to the cabinet to be able to deal with the upper band resonances via tuned resonators limits their usefulness to getting much below 25-30Hz. IMO. It's just my own variation on a 6th order bandpass mixed with a rear ported horn or whatever you want to call it. It's nothing new really, but the way I design them differs a lot from the way I had always seen them done. The most similar are pro audio designs with a big emphasis on the horn section and a por
  16. I've been messing with a more compact single 21" version more similar in size to the half Skhorn that was originally planned. It won't be drastically smaller but I'm hoping to chop a few inches off here and there without losing too much performance.
  17. Are you sticking with the box dimensions posted earlier of 20x26x29.35"? It sounds like you would be placing the driver and ports on the 20x26" face?
  18. It's hard to say exactly what is going on since there are so many variables. What voltage is being applied to the terminals during the measurement? Is the impedance really 15 ohms or greater? Is this 2 8 ohm drivers in series? Are you using a generic mic sensitivity spec or do you have an SPL calibrator? Mic sensitivity specs can be suspect in my experience. Pressures inside a cab can get very high especially if testing for system output capability. Finding a mic or sensor and mic pre-amp that can take it won't be easy or cheap most likely. Don't forget that despite subs bein
  19. Here is what the response for the sealed SHS-24 in 300L (10.5 cu ft) would be and the excursion profile at 126.5 volts, which is the maximum for the SP1-6000. Specs are based off of what I measured from my D2's but scaled for D1's so the impedance is correct. Semi inductance specs are used. Basically this is a 28" cube. As you can see this looks nothing like winisd. I'd suggest learning HornResponse if you are serious about designing speakers. I wouldn't worry about the excursion passing 50mm below 4Hz. No driver is linear with power out to that level and content that low in freq is very unli
  20. Here are a few comparisons. This is still using the big 850L enclosure but cutting down the vent length and area and tuning to 10Hz. Light grey line is your original plan. Once you add room gain to this that peak at port tune is going to be WAY too hot. It'll have to be addressed with the HPF and EQ to cut it back anyway or anything that hits that narrow frequency range is going to be heavily boosted relative to everything else. Also this is just an absolutely huge cabinet. Outer volume will probably be approaching 40 cu ft on your original plan. This is simila
  21. Hey man...Unfortunately what you would be building would be nothing like the winisd sim... You are looking more at something like this.
  22. I've been thinking about this myself. The SHS-24 is a tough driver to tune really low and port well. It moves a ton of air but it doesn't really call for a very big enclosure for a smooth response. Big air spaces cause a large peak at the port tuning. It's difficult to get enough power on it to effectively use the excursion also. It really depends on your goals and how much you are willing to compromise. The cab you've specified is about 850L with a vent area of about 871cm and a vent length of 169cm. Tuning is around 12.2Hz. Personally I would not use a vent that long. It puts the
  23. I believe I described how I determine port length earlier in this thread, or perhaps it was the Skhorn thread. I can't remember where exactly. I use line sketches in SW's and previous experience to determine the functional length. I'll see if I can find the post. Edit: It was on page 10 at the bottom of my long post. I'm surprised that you have ended up with an even longer length.
