  1. Looks like a hell of a party! I still haven't got my 4th together yet but my next event is in just over a month so i've finally got a reason to do it. Been a terrible couple of years for the event industry and the future isn't looking bright for a while yet. Got some new amps for the top end that will hopefully be here by then as well, a couple of Powersoft M50Q which means il actually be able to lift my amp rack in and out of the venue finally (dropping nearly 60kg off the total rack weight)
  2. JM living the dream ❤️ Cant wait to get mine back outside again, we are back to crazy restrictions in relation to entertainment events thanks to another covid outbreak, got 3 more parties booked this year but they keep getting pushed back until restrictions ease. On the plus side i should finally have a chance to build my 4th soon and do some comparisons with the Dayton 18s I bought
  3. Good to see some more SKRAMs getting use at outdoor parties! I built my 3rd for a party at easter, still with the 4x 10" car audio drivers as I ran out of time for testing the Dayton 18"s i bought. Ran for 3 days with 4x Martin W3s for top end and everyone loved it, so many compliments on the sound all weekend! Will be building a 4th soon to finally test the 18"s so i'll keep everyone updated whenever that happens.
  4. The B&Cs aren't too much more for the actual driver in AUD, its the shipping that's the killer, I can buy a whole extra Dayton for less than the price of shipping for 4x 21s of any kind that I've found so far. Whereas that store seems to already have Australian stock of the Daytons and shipping is basically free. @chrapladm me and a friend in Melbourne are planning to get 2 each and hoping to spend around $7-800 or less per driver including shipping. He's just finished his first cab, followed the plan a lot more closely than my first 2 so will be good to compare!
  5. Still looking for something I can get to put in these for a reasonable price in Australia without $1000+ shipping, the best I've found so far is this: http://www.theloudspeakerkit.com/rss460ho-4-18-reference-ho-subwoofer-4-ohm?fbclid=IwAR1JAm7KnbBwCsonNZ9AorrNEzcOgoq7e0ZhdofCSj_un8zpBBL20hlqiqw Power handling is obviously a lot lower but I don't have that much power anyway, good sensitivity and a fairly low FS, is it even remotely suitable for bass music in an SKRAM? Nominal Diameter 18" Power Handling (RMS) 900 watts Power Handling (max) 1800 watts Impedance 4 ohms Sensitivity 93 dB @ 2.83V/1m Frequency Response 20 - 500 Hz Voice Coil Diameter 76.2 mm DC Resistance (Re) 3.2 ohms Voice Coil Inductance (Le) 2.24 mH @ 1 kHz Resonant Frequency (Fs) 18.8 Hz Mechanical Q (Qms) 4.05 Electromagnetic Q (Qes) 0.35 Total Q (Qts) 0.32 Diaphragm Mass Inc. Airload (Mms) 499g Mechanical Compliance of Suspension (Cms) 0.14 mm/N Surface Area Of Cone (Sd) 1,164.0 cm² Volume of Displacement (Vd) 1,484.1 cm³ BL Product (BL) 23.4 Tm Compliance Equivalent Volume (Vas) 272 liters Maximum Linear Excursion (Xmax) 12.75 mm
  6. Damn I wish it was that cheap here in Australia, an 8ft x 4ft sheet of 18mm BB is over $200 plus shipping for me.
  7. I have a few Martin Audio W3 passive 15s that I could use if I want to go that loud. This system is aimed at smaller speakers, for quieter/closer listening with more emphasis on low end extension. I will experiment with larger folding baffles though, thanks!
  8. This is pretty close to my findings too, I ran 80hz on bass music and 100hz on house/techno, I'll probably try 110hz next time for a little more punch. 12db LR for both, I haven't needed a high pass yet as I've running bugger all power so far.
  9. In the video he said around $1000 canadian dollars
  10. The 21DS115-4's would be ideal, but any of the other drivers that suit these would also work. I'm in Adelaide and have a friend in Melbourne building some of these also, the cheapest we can find so far is Parts Express ebay site
  11. Does anyone have a hookup for a place in Australia that sells drivers that suit these, or an American company that wont charge separate shipping on each one? I'm almost ready to upgrade to some 21s and they're all outrageously expensive to get to Australia
  12. Had my next party on Sunday on the beach with my 2x skrams and 2x Martin W3 tops running from an inverter in my Prius from 2pm till nearly 2am, averaged around 1000w into the whole system (including the CDJs and amps and a few LED lights) and used about 5L of fuel in the car. Around 150 people at the peak of the dancefloor, everyone seemed to love it! Definitely need to build 2 more of these things and upgrade to the proper drivers for even better sensitivity to keep up with the tops
  13. Finally got around to doing some measurements, I'm no expert but here's what I've got so far. 1 sub in the back yard, running off 1 channel of an EV Q1212 at 8 ohms (havnt measured gains or anything yet, just sitting on what sounded good at my last party). UMIK-1 sitting 1 meter from the front, both flat on the grass (UMIK on the stand it came with) The green line is no crossovers, just straight from my PC, through the aux jack into a pioneer DJM2000 mixer, then RCA to Mosconi 6to8 DSP and then RCA>XLR into the EV. The orange line is what I ran at the last party, 2x 80hz 12db LR filters in the Mosconi 6to8. 1/48th smoothing on REW Sorry about the dodgy phone pics
  14. After much deliberation and reading many threads I'm starting to think that rebuilding the 2 monitors to include better low end extension is a better idea than a separate sub. Even that tapped horn design is too big to fit in the car as well as the 2 monitors unfortunately, but if I have 2 larger boxes rather than 3 smaller ones it might package nicer. Next step is to do some modelling and figure out what alignment to do, sealed, ported, bandpass? 1 or 2x anarchy per box? Etc etc
  15. Unfortunately not, they are quite old now and I've lost the boxes and paperwork that came with them, the website only has the specs from the 2017 model onwards which is the series after these so I'm not sure how much different they are (I'd expect they're close but probably not close enough for an accurate model)
