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! |

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! :) |

Jeg ved ikke lige om jeg har stirret mig blind på skærmen, - men jeg synes simpelthen ikke jeg kan finde en PM funktion? :) Edited by benjicube - 17 April 2022 at 8:40pm |

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.
