  1. A 12 inch driver will not play high enough to blend with tweeters.
  2. A ten can be made but the Ethos motor has WAY too much motor force for the weight of a 10 inch cone. As it is I am adding 35 grams to the moving mass to the 12 to get a proper response. If built the 10 wouldn't sound as good. I could however add about 125 grams of mass to make the response acceptable.
  3. And there is a chance for sleet/snow, icy road conditions here.
  4. My first appointment stood me up so have been catching up on drawings. This day needs to hurry the fuck up and get over already.I get to leave in about 2 hrs on my way to work out of town all week.
  5. The below graph is the Ethos 15 Kms curve. This is an expected curve when combined with my cones (surround plays a part in Kms). The spider pack for this curve is 3 stiff and one soft spiders. The below is another 8 inch progressive spider that is available. By viewing the graph it can bee seen the suspension only changes ~10 percent from rest to linear xmax. Versus the 50 percent increase in stiffness with my parts. This with ~1.7mm of creep are two reasons why DSS customers are reporting an increased tightness and transient response compared to other set ups they have ran.
  6. received a few parts. I don't have much time to upload but I thought I'd post this. An 8 inch spider with dual sewn tinsels. Each tinsel is rated at 100 amps max. If you are running dual one ohm coils this spider will allow for 40,000 watts max per each coil. This is the same stiff spider used on the Ethos. It is a true progressive spider that is measured 365 grams at 1mm.
  7. I suggest ^ and buy the 7th edition version of the cookbook. It will explain in detail of how to go about building to a desired response and Q. And how to measure, tune, and adjust if need be. I personally wouldn't build a BP enclosure for a sub stage intended on playing the full sub stage. The transient response on a BP enclosure with a large passband will have a much degraded transient response compared to a ported box. Again this is explained in the cookbook.
  8. With the lay a way it only costs you $2.95 a day.
  9. Maybe in LA, not in La
  10. we are expecting ~200 people to show up for our gender reveal party.
  11. got my work cut out for tomorrow. Two 120 pound hogs, 25 pounds of sausage, 50 chicken leg quarters, 20 gallons of jambalaya, 80 hot dog, and a partridge in a pear tree
  12. SPL coil is 45mm and daily coil is 62.5mm xmech12 spoke basket allows for 45mm xmech
  13. A 15 version is on its way to me via FedEx. Next week maybe a few pics and if y'all are good enough a free air video or two. Gonna make a test burp box and see what it'll do on low power.
  14. RMS as defined by Theile and Small and used by Klippel is not average voltage x average current. It is the average of the instantaneous power readings gathered by testing. Voltage and current is not gathered averaged then tallied at the end. The instantaneous power is calculated so many times a second and is averaged at the end of the test. Just taking the average voltage and average current and then multiplying them would not give an accurate account of power. It's an algorithmic expression that incorporates multiple instantaneous power readings over time.
  15. sorry can anyone elaborate on this for me, I think I might learn something :-)RMS stands for Root Mean Square. It is the mean average of power in a given set of time. And that is all that applies. The correct term to give for a thermal rating would be Pmax which is the maximum thermal RMS power that a transducer can handle. A more appropriate rating to use is Pemax which is the RMS rating needed to hit a targeted Xmax in a given alignment. RMS just means average. It isn't a "Limit'' of anything.
  16. Does this mean we have until 3-15? or do we still have to pay them off by 1-15? Buying this Avalanche hurt my funds bad this month. Customers have 4 months from their original initial payment. New customers have until the Jan. 15th to lock in sale pricing.
  17. Gonna be a looooooooooong night doing nothing
  18. And you won't until you get settled in a field for a while.
  19. just about finished the box....gonna make ya'll wait for pics but I think it looks and sounds damn good. Gonna start hacking up the doors in a few days. Gotta wit for it to warm up can't work in this blistering 40 degree weather.
