I'd be curious to know what the lightest version of this sub is (without compromising performance)? So a half sub is the same size box but with fewer drivers? /.../ But Tim said it out performs subs costing 3x's as much, so say commercially available subs in the $2,500-$3,000 range, right? |

And what kind of spl at different frequencies are achieved? I'm a little confused on this as sometime people talk about full space and half space measurements, not sure what they mean. |

So Oscar, when you say every mm is cautious, do you mean that in order to get all these strange angles to line up, you've got to be super precise? |

So, if this is a passive box with speakers, nothing else, what kind of wattage does it take to get the full sound out of this sub? Are there specific amp models that have found favor for this sub? That must be on hellofa 12" speaker to perform like that- but 2 are used, right? |

Is this design/speakers efficient compared to other subs in this league (which of course becomes an issue when blowing fuses and paying the electric bill for a show). |

I saw a post comparing it to a massive eaw box (KF940), and that sucker costs over 2 HUNDRED THOUSAND DOLLARS!!! That boggles my mind. |

I'm still of the opinion that a Sticky like I described, and other means of navigating this forum for beginners, would be a friendly welcome to the start of a considerable journey. |

Part of the whole "Educational" learning experience is not having the the answer handed to you, but all of the learning that you get while searching for the answer, not so much the answer itself. Yes, you get the result real quick that way-but a lot of the whole DIY experience is the knowledge (good and bad) that you get along the way TO the answer. |

I did a quick search when I saw the topic on comparing the EAW KF940, and the price I saw was astonomic, and it was used! Looking again I'm not finding the link. Didn't look that far, but I didn't see any pricing for the KF940. Is that a discontinued unit? What's its approximate price? |
A sticky won't be good enough because then PMs will go to that person asking specific questions. I wouldn't even dare undertake such as task because it will never be good enough for everyone and someone will always complain.At the top of the LSP documentation page a few lines that read:80hz and under.SPL of properly built LAB see graph lower on page.Impedance of properly build LAB see graph lower on page.Weight of properly built LAB 240lbs +.1 cab won't do much unless corner loaded, need at least 4Cab is 1/12 of horn mouth, which is 27hz.Cost of drives see links below.Input power see "insert message thread here" or more then 1 watt less then 4000w.Cost of plywood? Where do you live, call a shop. Probably more then you think it should cost.How long will it take to build? A lot of time! Are you a hobbyist? A pro? You will know once you have finished. There is no Version 1 of the driver, only Version 2 as 1 was a prototype. Version 3 was a redesign of the cab for a living room.
I've built more than a dozen... the first took 2 days and then I think we built 6 in 2 days (all the jigs were already made by then, and you'll want jigs, otherwise you'll tear your hair out.Determine how many you want to build and cut all the parts out at the same time if possible. I think someone posted a price north of $5000 for the 940's back then?The thing that really still satisfies me is the look on peoples face when things rain down off the walls and ceiling when those things get going...I can't tell you the number of times band guys, business owners and other sound companies come up with total disbelief of the low end.. and want to know how THEY can get some of those!G

1. Approximately how long it would take for someone with moderate woodworking skills to make one of these boxes. How about the second one?The first 2 labs I built took me a week. Half of that was spent setting up jigs so I could build more later. 2. Is there just one or are there several sizes (they seem huge from what i've seen). What do they weigh? What does it take to man handle them?I'd recommend building the basic PSW version.. There is much work leading to this design.. all other "Variations" were for the most part single person creations.3. What's the approximate cost for wood, speakers, etc.$500 10 years ago4. What do they compare to?There are not many pro touring subs out there that sound as "hifi" as these. Danleys of course.. but I would digress that not to many tours are carrying those :/ And they can take a beating.. 5. Is anyone making parts (such as cutting out all the pieces that you then assemble and glue)?You can hire a CAD saw to cut for you.. but that takes all the fun out of the project!6. What amplifiers and DSP are used?I like QSC + Powersoft (you can read about 345431553 articles titled "whats the best amp for a lab")I don't know of an EAW sub that will compare to these..
I would say that we do have a super vibrant, and very intelligent community here on PSW. The most experienced people in the industry are on here. And the folks who design and manufacture the products they use are right here also.They are so intelligent that they prescribed reading the entire Lab Subwoofer forum. They do this because this is what it takes to build the Cabinet. What I enjoy most about this project is that you get to be a scientist too. You have to chance to build it the way you think is best. You have the facts from the creators. The opinions of the other DIY folks and the opinions from the audio pros. Have any of your questions about the Labhorn gone unanswered? I doubt it. These people here on PSW are punctual too. If I need info about anything at all, I can get it here quickly. There are people sitting at there computers right now wishing you would ask them something technical. Just sitting there.. Ready to slap you with an equation. No need for a sticky. It would just tell you to read all this info, and don't cut your fingers off.
Over the last two weeks or so, I have read every thread on this board that looked to be LabSub-oriented. All 25 pages of thread headers.There are a lot of interesting nuggets buried throughout. However, there is also an overwhelming redundancy.Even after all that, many threads make references to early discussions that no longer exist. These would be discussions documenting the evolution of the requirements specification, early design parameters, etc. I assume they must have gotten lost in some site re-org. I'm sure they exist somewhere, but it ain't in the LabSub forum.Soo....If anyone would take the time to index the *primary* content, and make the index a sticky, I think it would be beneficial.Further, if anyone knows where the early discussions are archived, at least a link to that should be a sticky.

So.... I had my say, a few other people did as well, so that's that. Good to see enthusiastic diy'ers chasing a worthy project and supporting one another. I just wish these subs weren't so big and heavy! But i suppose that's the key to their outstanding performance. For my needs at this time I'd be more interested in subs under a hundred pounds with a smaller footprint. PS Hmmm.... don't know why, but on my computer, on this second page of posts, the text doesn't wrap normally, goes 3-4 times further than it should (requiring left to right scrolling). |

That's because you used the "code" format tool rather than the "quote" tool. Use the "quote" radio button, next to the "reply" button. |
