    The Bass EQ for Movies Thread

    I watched it again recently after another house curve improvement and loved it even more. I also played the race scene at the beginning as a demo (full "-5" MV with house curve, so peaks > 120 dB) for some family including my step mother who wasn't an audio enthusiast in the least. I think I changed her mind. Edit: Among our conversations was her complaint that action movies (which she likes to see "big") in movie theaters are just way too loud a lot of the time. I explained that, even though the mixers work on dub-stages calibrated using the same flawed standard as cinemas, the dub stages still usually sound way better than cinemas. So what sounds too loud in a cinema was probably just "really exciting" for the mixers. I think the demo cemented that understanding quite well.

    Second floor apartment? Really? When I have people ask about my subs and find out they’re in an apartment or connected condo, I tell them my subs come with eviction notices. Good luck with those and the fight to keep them. When I first turned on 3 sealed 18s for my wife, I said if that was too much vibration, we could put rubber feet under the couch. She looked at me and said, “you most certainly will not, that was awesome.” And I’m sure people ask why do you need a car as fast as a Bugatti. If you have to ask, you just don’t understand. Luckily, our subs are a heck of a lot less expensive for their capabilities than someone buying an exotic car.

    Someone over at AVS received an sp1-4k or 6k recently and looks like they are using an internal cover again on the plate models. Glad to hear Brian's potentially still got some input there even if he does spend most of his time sitting on a beach drinking rum now.

    MicroWrecker build thread

    It would be interesting nonetheless to do a comparison between a MW and a 24" sealed sub From what I can read here and there the magnifying power of something like a tapped horn is in the vicinity of factor 3 (or even more), so a 15" in a TH would roughly equate into two 18" direct radiating units or thereabouts? Reading through the big "Danley DTS-10 "Super Spud" DIY kit"-thread though it's quite obvious the DTS-10 sports a different kind of overall sound delivery and impact compared to a series of 18" DR's (poster 'MKtheater' in particular provided a lot of intel in the form of actual listening impressions here), which points to the tapped horn itself as something that leads to a distinctive bass imprinting (which, perhaps, could also be said about direct radiating solutions, so not to hand a "character-baton" to TH's as such). On a side note I saw my completed MW's today (at the cabinet maker's workshop at a local theater), that is: one of them only needed some clear oil and finishing touches around the edges, while the second one had just been assembled today and was still wrapped in clamps. What dawned on me though when I finally laid eyes on them "in the flesh," so to speak, was their sheer size. Holy freakin' moly - they're huge..! 😱 I've measured out these things at home to plan for their placement, but nothing prepared me for the solid surfaces of these when I finally saw them for real. Subjectively they look something like 50% bigger than I'd imagined. A lighting technician from the theater came by as the cabinet maker and I stood there looking at the (almost) finished MW, me still in amazement, and wryly asked: "Isn't one of them enough?" Having now been confronted with the sight of these I hesitated a bit, then replied: "Ooh yes, certainly going by the sheer output this will be able to produce, but.. " and then followed a less than convincing speech, possibly because I now felt it to be quite hilarious, about smoother room respons with 2 differently placed subs (or more) and all that jazz. Needless to say the lighting technician seemed skeptical about my explanation. With a smile on his face the cabinet maker then followed with the question "For how long will you be allowed to keep these, and at what cost?" We just laughed Tomorrow they'll be transported to our home, a second floor apartment. More to come, if we'll survive the endeavor of getting them up the stairs..

    It’s not quite a sealed 24 but it might wreck something. Lol! I kid. Looking great so far.

    Finally some pics of the assembly process. The MW's of @lilmike are finished on Wednesday.
  15. I'm way behind on the MI series so probably won't see this one for at least a year or something. I am getting caught up on a lot of other recent movies. Here are some recent watches and mini-reviews, in no particular order: '"Maze Runner 2" (Atmos): boomy 40 Hz effects but extremely dynamic soundtrack with very crisp, tight gunfire that really pings the chest; played at or near MV "0" "Maze Runner 3 (Atmos ?)": hump / filter at ~25-30 Hz is very obvious among the rather relentless and monotonous bass; relatively disappointing ending; played at more typical MV "-5" "Avengers" (7.1): uninspired sound design (especially in the surrounds and bass); dynamics not completely massacred like in "Black Panther" but still thoroughly screwed up; big effects lack impact and come across as harsh; I'm playing this at MV "0" and there's nothing there but a lot of wasted headroom; way over-hyped/over-rated movie, especially the ending "Solo" (7.1): played at or near MV "0"; very heavy on treble and treble effects, many of which are surprisingly dynamic; limited use of bass with some repetitive 28-30 Hz drone; ignoring the bass, I really like this track for its life-like treble and absolutely loved the movie, which was underrated IMO "Jurassic World" (7.1): mostly entertaining movie with some nice bass; I thought it was filtered and was expecting 30 Hz boom, but a lot of the smaller effects were very palpable; played at MV "-4"; like many movies, I wish it had more mid range "Dawn of the Planet of the Apes" (Atmos): decent movie with fairly unremarkable (and mostly filtered / boomy, IIRC) bass; excellent use of Atmos/surrounds for ambiance; loud with bad clipping; played at MV "-6" and then backed down to ~"-9" after my ears got tired "Incredibles 2" (7.1): hump at 30 Hz which seemed to rob the presentation of a lot of slam/impact; decent macro-dynamics (for recent Disney), but otherwise unremarkable; I wanted to like this movie more: it starts out exploring a theme based on contemporary social issues but the ending doesn't provide a satisfying resolution to those issues, which makes the film come across as exploitive in hindsight; I don't think it will age well like the original did FWIW, my opinions are very mixed as far as recent Disney/Lucasfilm/Marvel soundtracks goes. I think some of the soundtracks are very good, some are mediocre, and others are crap. The one thing that's consistent about these tracks is a lack of consistency. Reference playback level is typically higher than other films, except when it isn't (e.g. GOTG 2). Re-EQ application seems to be inconsistent, with some films getting it and others not. Some films with higher reference level use the extra headroom for very nice micro-dynamic sound; others have aggressive limiting, leaving most of the headroom wasted. Overall, I think the Star Wars and Pixar films have faired better than the Marvel films, especially the most recent ones. Maybe it's a sign that Marvel as a franchise is running out of gas?

    Ricci's Skhorn Subwoofer & Files

    Going back to my issue with the drivers in electrical series, I can say there is absolutely no difference between them linked like that or parallel. All my tests and measurements showed me nothing changes, a small voltage difference is present, but only 1-2 V at 60 V sines.
  18. Ah I see, so do you think that is where the 3-5hz content is mostly? Probably to make the audience as shit scared as Tom Cruise was trying to get to the helicopter hahaha!

    Ricci's Skhorn Subwoofer & Files

    Reading through this thread has been really inspiring. I discovered new drivers that I would consider reference (IPAL and its brothers), and learned more about horn enclosures. It makes me want to attempt building a small horn loaded subwoofer for use with desktop speakers and the such, just for its high efficiency.
  20. Oh well, the ever-delayed two MicroWrecker's of @lilmike will now see completion (dare I say it?) on Wednesday. Pics - a few, at least - should start rolling in Monday or Tuesday. The main reasons for the delay are: an extremely busy cabinet maker (working at a theater with some big productions just about to premiere), and that the CNC-cut panels had two of them, the driver panels, with a wrongly aligned driver hole cut-out (driver panels have been re-cut). Fortunately everything else fits perfectly, and the assembly has slowly started up (to speed up from Monday). A few days ago we double-checked the fit of the holes for the driver bolts. Speakon terminals will by mounted at the bottom tilted back panel. 13-ply birch looks great. Initial pic of the B&C 15TBX100 on the driver panel for screw hole mark-up, and two CAD-pics of the MW attached.

    I have a TH50 build that I was looking at doing for fun using a different driver. But for now I was looking at finally building this Skhorn in a single driver version. Moving houses so lots of things will be changing for myself but projects will finally be started and completed.

    Ricci's Skhorn Subwoofer & Files

    I have heard the TH-50 way back what must've been a decade ago now...It was quite powerful in the basement of the home that we demo'd it in. Ivan also brought a Danley CS-30 and a THspud from what I recall. The TH-50 uses a beastly 15" driver (MTX 9515-44) and it's a huge cab but it does deliver the goods. Since the thread is about the Skhorn perhaps we should move discussion to a build thread on the Microwrecker. LilMike is someone I've talked to for years and met before. He's a good guy and he lurks around here, so if you have questions don't hesitate to ask him.
  26. Ricci

    Which sub(s), tops, divers, amps?

    The ultimate Skhorn performance would be with 21Ipal drivers. These are very expensive and require equally expensive amplifiers though. I would suggest the B&C 21SW152 or 21DS115 as a lower cost but still highly performing option which will be a bit easier on the amplifier choice and cost as well. There are 2 drivers per Skhorn cabinet.

    Looking forward to that indeed 😎 Truth be told I'm absolutely clueless as to what awaits me with the MW's. My last sub was a single SVS SB16-Ultra - no slouch by any means relative to its size, and quite musical - so I take it I'm in for a change, safe to say, with a pair of horn subs each fitted with a driver the same size as the one used in the SVS. Overall impact comes to mind here.. 😬 I did contemplate adding a second SB16, which I'm sure would've made for a very good result, by why not try something altogether different (and more powerful) while you're at it (I'm rather drawn to pro-style sub bass), for what will amount to the same-ish sum of investment? Further off topic (sorry, Mr. Ricci): have you ever heard Danley's TH-50, and if so how did you like it? I know the MW's are inspired by it (as is the Ghorn, I guess), so maybe some impressions of the TH-50 would give me a slight bearing - if indeed this model is anything to go by in relation to the MW's. Yeah, 25Hz Ricci-measured response from the SKhorn could well turn out to be quite sufficient with movies when all has been said and done with the contribution of room gain. I do have concrete walls in my listening room, but hardwood floor and a ceiling material I'm not aware of (my guess is some kind of plaster), so what that does for room gain I couldn't say. If memory serves me correct you're using a total of four 21" units (sealed?) for your subs, right? Using only little imagination I take it those could potentially level your home at "full tilt" or war volume as well? I believe a pair of MW's with the B&C 15TBX100 (which per lilmike is mechanically limited in the MW at about 600 watts) could hit 130dB's with 400 watts, so perhaps in the same ballpark compared to your setup

    Thanks for writing back, Ricci. You have made the Skhorn's sound more impressive than the Tuba 60's, size and performance do matter. Skhorn seems to win out! Cost doesn't matter at this time, we might as well invest in quality drivers instead of cheaper drivers if they outperform. Which is the choicest of all the four drivers you have listed. Is it that question not as easy to answer/are there other factors ought I weigh even if cost is negated? Wishing you a very happy New Year. p.s. ... I have attached the genres/styles of music will be used for outdoor parties. They will played off a Pioneer DDJ SX's mixer. With this list I hope this will help inform your choice of driver. I may not be necessary, but it might well be. I think it's just an interesting read. It took a day to organize this document. We're looking for the best as my wife and I live simple existences but our ambitions to be the best by providing the best is at the core of what we do. The best music through the best sound system. A passionate investment, a commitment, and well worth striving for. I see your crew talks shop about other subs out there on the Skhorn build thread, if there are other subs to consider that have the excellence of Skhorns', since we're in Canada, please help us by letting us know. Respect, man. And where should we purchase the equipment ... we really don't know. If this is all to much for you, answering all these noobite questions, all well and good. Cheers. GENRES.rtf
