  1. Last week
  2. Pretty sure 18" options were talked about for skrams and skhorns at some point - might even be in this thread. Design stays the same, but you sacrifice output based on the lesser driver.
  3. For the Othorn design Ricci mentioned that both, the 21NLW9601 and the 18NLW9601 would fit, although the design was also made for 21" chassis. I guess I'll wait if Ricci is jumping on my post.
  4. ok, there are other drivers that maybe FIT on the SKRAM is the HR screen for the SKRAM available ? if not i guess we need to wait till Ricci chime in to see if they fit BEYMA 21LEX1600ND , RCF LF21X451 , LaVoce SAN215.30 , 18Sound 21LW1400
  5. JAMI, you rock !! thanks for sharing your CNC work with us! For convenience I packed al your CNC files on a rar archive (for the couch potatoes like me ) SKRAMCNC_JAMIPACK.rar
  6. Changing dimensions to an existing design is a big no, what you can do however is to build the cabinet as it is and add an extension reducer ring so you can mount your 18" driver in to the 21" baffle, that way later on you can swap the 18" for the correct driver. i wish Ricci published the HR screen of this design, that way you can sim different drivers in it. but i think there is no much leeway as this cabinet need a very strong motor driver with military specs cone so there are not many 21"s that fit the bill, and the ones that fit are already listed on post#1 My 2 cents.
  7. 👏👏👏👏👏 Great job! This will defo come handy when i will finally get to build my first pair.. hope i'll make it this summer.
  8. Not a great fan of downsizing designs to fit different size drivers, i honestly have to say.. but anyway, if you really need to do it, i would rather change the volume of the enclosure by reducing the height (giving up the air in the top part in particular) and i tell you briefly why: reducing cab width would mean to change reflex width, therefore altering cab's tuning and low end performance. No point in building this specific cab at that point, it would sound quite different from what others have studied, designed, and tested. Same thing if we talk about cab depth/ port length. In any case, remember this cab have been designed to hold inside a 21' woofer and tuned to the low freq IT would reproduce, so a 18' would probably have slightly less low end extension and other differences in parameters that you need to consider if your aim is to get as near as possible to the actual Skram's performance.

  10. Hi, my name is Peter and I'm living in Austria. 4yrs ago I built 2 ported subs with 18NLW9601 for the outdoor marriage party of my daughter. So far they work quite well (powered by a Proamp 3000). However, I'm always eager to satisfy my affinity for new designs. From what I've read in this thread - thanks so much to all contributors, especially but not limited to Ricci - the design works pretty well. Hence, I'm interested to build 1 SKRAM to compare it with my existing design. Would it be possible to shrink the cross-section area of the enclose to reflect the smaller footage of the 18NLW9601 compared to the 21NLW9601? E.g. reduce the width of the enclose? Gr Peter
  11. For clarity defs not referring to myself there 😅
  12. Bro the ego is almost as overwhelming as trying to figure out the driver interaction you must have going on there 😅 I’m no forum moderator but I do enjoy a bit of online chit chat now and then and I would say maybe approaching this whole “asking for advice” thing with just a tad more humbleness and tactful vocabulary you could find yourself with all sorts of great ideas, answers and knowledge from some of the folks on here who have got legit sonic wizardry rep. instead of the proverbial forum tumbleweed “2 months later…” auto post rolling through on ya 😜 Also why get yourself a couple 21SW152s and then come to ricci forum to ask bout b&c ported? Just build some Othorns or skramsalready… I guarantee you’ll thank me if you do. Oh and @Ricci too hopefully
  13. Kyle, did you end up setting up a patreon? I'd love to contribute to keeping this site up.
  14. New Member here. I don't even have plans to build anything yet but it would be sad if this was gone. I'd be willing to subscribe to a patreon (at least $5 per month) or something to help keep it going. Can anyone tell me what the latest news is on this? Where can plans be acquired if they are gone here?
  15. I modeled a CNCable version of the SKRAM fit exactly to the detailed plans provided by Ricci in post #1. Feel free to use them as a base. These are meant to be used with Adam Hall 3402 and Neutrik NL4MPRXX, so you might want to adjust the respective pockets and cutouts. I did not yet include pockets/holes for wheels.

  16. One of those wild ideas during COVID19 when we were all locked up inside. In all seriousness, I ended up buying an off-the-rack TV cabinet. The TC Sounds LMS-R 15" each sit in a sealed 2cu foot cabinet. Dual opposed bigger vented subwoofers, a dream project for another decade, I think...
  17. Hello Guys Could you please post a HR input data for half skhorn ?
  18. Thank you for the effort of designing this cabinet Ricci! We are looking forward to hopefully build some SKRAM’s soon! We are going to start off with two and build another two to the end of the year. 21DS115 seems like the cheapest option here in germany at the moment. Do you have amplifier suggestions to power 2 and later 4 of these beasts? We dont care if it‘s one amp to power all four, two amps per two cabs, or even one amp (Bridged?) per SKRAM. Also, do you recommend 8 or 4 Ohms?
  19. 4.5 Star Film links are now correct in first post. Vote on Oppenheimer if you get the chance. JSS
  20. Let us know what you think about the bass in Oppenheimer
  21. The 4.75 Star Films now have proper links, some images got lost on the PvAs of the 4.5 Star films that I am working on correcting. JSS
  22. Slowly I will start fixing the links in the first post. All the 5-Star films have correct links now. JSS
  23. So TDKR was kind of a mess, fidelity-wise. Lots of clipped tops make for a harsh soundtrack. Watching the movies back-to-back and with a surround system (down-mixing to 2.1 unless your AVR is doing it from an LPCM source will introduce dynamic compression by your AVR) is enlightening. I think TDK is one of the best soundtracks around, and TDKR could have been, if someone didn't just turn the gain up until every loud effect clipped. Another reason TDKR got such bad reviews here is this: This is the entire PvA for TDKR. But if you isolate the first 10 minutes: You can see it is a full bandwidth presentation with effects into the single digits. The rest of the film, however, is different: With a significant rolloff under 30Hz. The difference was easily heard and felt in a system that can reproduce under 20Hz. It is as if the ultra low bass knob was simply turned down. If you remember when TDKR was initially in theaters, a special 'Prologue' was released in IMAX theaters 6 months before the movie was released. It is my theory that this prologue was mixed independently and that mix was kept for the final film, and the rest of the film got highpassed when mixed. Unfortunately ALL of it is clipped. One of the worst cases of clipping in a movie I have seen, and heard. The first time I became aware of clipping was in Tron:Legacy, when I saw the BluRay and it was definitely different compared to the theater presentation. The effects dug deeper, but the sound was clipped in many places, confirmed by looking at the waveforms. JSS
  24. You can see here that TDK only clips in one channel, at only two points in the movie: This is the entire movie, all channels, L/R/C/LFE/SL/SR in order 1-6. Just after the one hour mark, the center channel clips in one place (marked in red), and once at the end. TDKR, however, is a different story: As you can see, the screen channels clip nearly throughout the film, followed by the surrounds, then the LFE. It is an utter disaster, and the soundtrack is very loud because of it (one of the loudest I have measured). JSS
