Topic: Restoring / Complementing old D.A.S. Audio system Posted: 18 April 2022 at 10:26am |

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?

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

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

Q4: I think I articulated that wrong. One whole K-8 unit is missing completely. This is also making me sad, because the other one sounds pretty sweet! 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?

Compression drivers don't get reconed you just replace the diaphram which often only involves using a screwdriver so it's pretty easy to do. But yes if you're missing a K8 that makes the rest a lot less useful. I'd say sit on these bits for the moment and decide what to do after you have the subs and QRX boxes functioning, if that system doesn't deliver the sound you want then have a look at what can be done with all these compression drivers.

Will definitely do that, - someone tried to convince me the the Delta pros were a perfect replacement, but I had my doubts... | The DL15x isn't exactly a beefy driver and it puzzles me that these cabs didn't get an EVX LF driver, but it's original to this cab and there is value in that as it will retain resale value and the OEM sound character. I like Eminence drivers and have used plenty of them but I don't like the Dalta 15B and think it's the wrong choice here. If you wanted to upgrade the cabs with a more robust driver there are lots of options to consider but that would involve replacing both units which will cost a lot more.

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.

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? :)

Never mix two different drivers in the same cab... especially sub drivers unless they are known to be a perfect electro/mechanical match. Also you cannot use a dual driver cab with only a single driver installed as that completely unloads the driver making it super easy to destroy. A small tear in the cone of a woofer is no big deal, if it has been repaired correctly the driver will suffer no loss in performance or life expenctancy. So you really only need one more functional driver, if a recone is unavailable use a G18 as other have suggested. |
This is all very useful knowledge, - thank you!

Also very nice to know! I have definitely misread/understood something about this! :) Will study further!

A box of some type makes stacking easier but it doesn't have to be sealed.. open back is fine.

Note, the QRXs will need processing, EV has black box settings in the Dx processors for them but a quick search hasn't turned up an general PEQ data. But you can roll your own, I've had really good sucess with DIY tuning of the DH2012 which is a DH7 cousin, as well as with other drivers like the B&C DE750.

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/
