Hello all! First post here... And this will be a long one, because I am a colossal n00b in this area, and have taken on a project where I have to learn many things along the way! (And I fully intend to study any and every subject needed, - but I am a great fan of not re-inventing the wheel every time someone needs a new car) I have been an amateur producer, and part time studio tech for a couple of decades! Also worked quite a few gigs as everything from hand, engineer, organizer, DJ, VJ, and everything else. I am also quite experienced with electronics, - but I am a software developer by trade, and have absolutely ZERO professional experience with speaker design/engineering! I have always rented/borrowed any equipment (or delegated that part), but now it was finally time to get my own system! It will be used almost exclusively for electronic music, - Techno, Psytrance, DnB and Breakcore! Coincidentally, a friend of a friend had a (very) old D.A.S. audio system, that me and another friend have now inherited, and are trying to turn into a functional system! As we are going to exclusively be using this sound system for non-profit events, we are trying to do this as cheap as we can! :) Here is a list of what we got, what is working, and what is not; - 2 x D.A.S. Audio BASS-218 (With 2 x G-45 fully working, 1 x G-45 that had a small tear, and has been glued, and 1 x G-45 that needs a new voice coil, or a re-cone) Q1: As two of the drivers are compromised, and quite hard to get as spare parts, I have been considering buying 2 x 18sound 18lw2400, and putting one 18lw and one G-45 in each cabinet. I am unsure of how that will sound, and if there is a better solution? (or better driver replacement) Maybe change all drivers at the same time, or ditch the cabinets and make 2 new cabinets with 1 G-45 each? - 2 x D.A.S. Audio Bullet-2 (With cabinets, but they suck, so I am thinking new cabs) Q2: As I understand it, an integral horn compression unit like the Bullet-2 doesn't really need a cabinet, except for weatherproofing. Is that completely bogus, or could I make any kind of enclosure? Q3: I am thinking the Bullet-2's would be great for kick-bins, - but this is based on knowledge solely from google, research I don't understand completely, and math that I haven't mastered yet! :) Any comments as to why this is either correct, stupid, or just completely wrong are welcome (and if one of the latter two; an alternative use for them) - 2 x D.A.S. Audio Unknown speakers, with D.A.S Audio K-1, D.A.S. Audio K-2, and K-8 (However, 1 tweeter is dead, and one K-8 Compressor Horn is missing) Q4: Would it make any sense trying to get the parts for "remaking" these boxes (or alternative drivers), or should we just sell the spares, and buy/make new mid-highs? And if the latter, - any suggestions on that part? But one DH7 unit is dead, and one DL15X unit is dead (So I basically just assembled it into one functioning Qrx) Q5: Would you recommend re-coning the dead DL15X (I will pay a professional to do it), or buy a new DL15X? ....or maybe two new alternative units, like the Eminence delta 15 pro? Q6: Should I buy 1 x new original DH7, 2 x chinese knockoffs, or go all in on 2 x new DH7? I figured we could use the EV boxes as intermittent replacements for the D.A.S. tops, until I find a another solution, - but at this point of my learning endeavour, that is pure speculation (/hope) For now, I have a L.A.B. 68:4, 2 x L.A.B. FP2400, and two L.A.B. Lucia 240 for testing units. I will soon get either 2 x TC XO24, - or a Lake LM 26 + either a XO24 or Behringer 2496, - so I will have either 4 or 5 way stereo speaker management, and plenty of ways to wire up this frankensystem! ANY and EVERY comment, idea, or criticism of this load of nonsense is VERY welcome, - and I apologize for my first post being the epitome of "I have no idea what I am doing, but please answer all my questions at the same time"....! But this whole project already threw me so deep down the rabbit whole, that after this second/third hand system is playing nice, - I am going to continue my study of psycho-acoustics and speaker design, and make speaker building my new hobby (and maybe a job some day)! ....Well, it already is. But I am starting out with a half-complete "kit" instead of from scratch :D If you've reached this far; thank you for reading! edit: yeah, sorry for the links :D

First of, you need to fix those links. They dont work  Second, DAS G18 is still on the market, and concidered to be a direct replacement for G45. I would not mix and match different drivers in the same cabinets. You could go with completely different drivers, but some calculations would be needed. G18 Will be a good choice ready to drop in the box. |

Yeah, sorry for that! I spent WAY to much time trying to implement links for every single unit mentioned, but it ended up like a corrupted version of a klingon dictionary.... So, I gave up on those links :P ...I will learn how it works before my next OP! :) But thank you very much for replying! That was definitely my original plan, but I have only been able to find a single G-18 unit on ebay (and I tried all the other 2nd hands), and it will cost me about 580 USD, including import tax and delivery to Denmark. I tried all the D.A.S. retailers in my part of europe, but none of them wants to sell single spare parts (And I guess it would cost a lot more if I even found one) ...so, either I buy this single, used driver unit, and never know if/when I will be able to get a new one(or when it fails, or when the glued unit cracks again), - or I spend about the same on two new drivers that are still in production, and somehow match the specs.... 2 x new G-18's would be freaking awesome, but it's a bit too expensive for me at the moment :( Maybe I should just mount one working G-45 in each cab for now, - and then save the G-8 upgrade for later, as the subs are kind of worthless without the rest of the system working ...but at least could be used at half power, - a single one of those G-45s driven 40% by a Lucia 240 made glasses and plates fall off the table, three rooms over, in a brick house! Thank you very much for your input! |

Send mig en PM. Det er ikke hver dag man støder på en dansker her inde 🙂 Og her har du et link til G18 enheder  https://en.toutlehautparleur.com/speaker-das-18g-8-ohm-18-11-inch.html |

Whenever I've needed to replace drivers, I will generally take a look at what's available from P-Audio. They have a good range, decent prices - and more importantly actually really good and reliable drivers. I especially like the neodymium range they have. Good way to lighten up your cabs! ------------- Earplugs Are For Wimps! |

I have 4x DAS Sub18 cabs, one has a blown G45, so too am looking for comparable drives. The Sub18s are extremely small cabs at 74x51x41cm! Tbh I'm tempted to sell my 4, i can get a 5th cab too. That said I've just seen that recone kits are about £110/

Will study further!
With this in mind, would you bother getting the missing originals, or just skip these and go with the EV's for now? The K-8 compressor is 300€ without the horn, and as for the K-1 and K-2 I can only find sketchy looking recone-kits. I've never reconed anything in my life, and think I'd like to do a bit of practice first on some cheap stuff, before I'd try this... Maybe just sell all parts?
I will find a local who can help me with the reconing, - maybe even teach me a thing or two :)
Anyways, thank you very much for all your great answers! :) |

Hey! Tak for link! Jeg ved ikke lige om jeg har stirret mig blind på skærmen, - men jeg synes simpelthen ikke jeg kan finde en PM funktion? :) |

A friend of a friend just heard that I was restoring the Qrx 115/75 system, and offered me 3 x EV sx80 in mint condition, for me doing a bit of programming for him (Like, the equivalent of about 130€). Would those make any sense in combination with the Bass-218 and Qrx units? Or would that just be silly? /n00b :) |

No just source an authentic DH7 replacement diaphram.. not a chinese copy. There is no need to ever replace a whole driver unless it has been physically damaged or parts are simply not available.

| The sx80s wouldn't be any use as PA speakers alongside the larger boxes, but they could be useful as DJ monitors. |

Det er fordi du skal op på 10 indlæg før det bliver aktiveret Tænker du nemt kan opnå det ved at skrive på et par tråde. Angående SX80, så er de ikke meget værd til PA. Så hellere proppe nogle penge i at få de andre højtalere op at køre igen |

Yeah, I think I mistook them for some completely different models at first. Thanks! :) |
