Dynaudio Rear Shelf Speakers

[_HighVoltage_]

I was at the junkyard today just browsing.

However I scored a S90 front lip (project snowplow begins this summer) and then I saw a fairly complete 98 C70.

Interior was mostly intact apart from the dash cover (somebody had taken it already) and the seats, but I noticed it still had all the speakers.

Got the front tweeters and puled the rear shelf speakers thinking that they might fit, but I hadn't done a lot of research.

Now after I've done some reading up, it seems like the rear Dynaudios would be a mistake and won't fit right anyways.

As for the front tweeters - one turned out to be blown, the other is working but sounds softer and quieter than the stock one. By the way, the stock tweeters were 8ohms! So it seems like the front speakers are also wired in pairs.

But anyways, should I return the rear shelf speakers, or are they worth the upgrade?

If you can return them, I would. Or sell them on Ebay. C70 Dynaudio tweeters (or any speakers from that car other than the center channel) are not an upgrade in S/V70s at all. Glad someone took the time to research though and come to that conclusion without us having to tell you!

Yeah, I was a little disappointed when I plugged them in (just unhooked one of the dash tweeters). I'll go return them tomorrow.

I must challenge this assertion. The Dynaudio speakers are 100 times better than the stock Volvo speakers. The reason they probably dont sound great if you just pop a few of them in your car is that they are not very efficient and require lots of power. Way more than a head unit provides, and even a lot more than the extra amps in the T5 and R models. Thats why the C70 has a 100Wx4 amplifier. I have the Volvo Dynaudio kit for the V70 and Ill be using a 150 watt/channel JL Audio amp for the front speakers and a 75 watt/channel JL amp for the rear speakers. I used the same JL 150 w/ch amp to drive Dynaudio component speakers in a previous car and it was perfect.

Search for Dynaudio and youll find they are regarded as one of the best speaker brands. The Volvo/Dynaudio speakers are almost as good as the regular off the shelf Dynaudios and are far superior to the cheap paper-coned Volvo speakers. Youll also find most people recommending 100-150 watts per channel of good, clean power.

The other problem with the C70 Dynaudio speakers is they dont physically fit in S70s or V70s without a lot of work. But I think you are misleading people if you say they are not an upgrade.

OK, I'll bite.

First of all, we aren't talking about the same thing here. If you have the V70 Dyaudio kit, that's awesome (and I'm jealous), but that has nothing to do with the far more common C70 Dynaudio setup. The V70 (and S70, for that matter) kit is specifically designed for those cars, and operates at an 8 ohm resistance. I imported (and regrettably sold) the last new in box S/V Dyanudio setup a couple years ago that was available in the world so I know just how special that kit is. The S/V kit is 100% different than what the average person on here will find in a junkyard C70. Therein lies the problem: I've probably seen half a dozen threads in the past year alone where people get all excited about finding a C70 in a junkyard somewhere, pay for and pull the speakers, and then come on here and post asking why the speakers sound like trash or don't work. So then you're left with a couple of paperweights.

Second of all, the C70 setup comes with more speakers from the factory than an S or V70, and each Dyanudio component has a specific purpose. For instance, there are tweeters, mid-bass woofers, crosspovers, subwoofers (parcel shelf), etc . Adding a couple of junkyard speakers from that set (in the case of the OP, the two parcel woofers), it is not going to do squat to improve audio quality. How much power is flowing to them has no bearing on that. Anyone looking for bass would be better off getting a dedicated subwoofer and running that. Or designing a system from aftermarket components and installing those.

Finally, I think you're confusing quality of a brand with quality of a product designed for a specific application. Bang and Olufsen make a nice product for Audi and Bermeister makes a sweet Porsche setup. That doesn't mean that I'm going to go to the Porsche dealer and order speakers for a 911 and drop them in my Volvo. In a vacuum, sure, I agree that a speaker manufactured by Dynaudio (or Bermeister or Bang and Olufsen) is better in quality than a standard paper-cone Volvo speaker. But that doesn't mean it will sound better as part of the setup because it's not designed to serve the role it's being asked to serve.

Now, if someone wanted to find a way to add all 11 C70 Dyanudio speakers to an S or V70 and wire/power them correctly, that might sound good. But there's no way that adding two "higher end" speakers to the rest of the system will do anything and in fact it tends to make things worse. I never said that there aren't better products out there than a standard 15+-year old paper cone speaker. I did say that you can't magically improve the sound quality in a 70-series (or 850, same principle) by adding speakers from a C70.

I imported the last new in box S/V Dyanudio setup a couple years ago that was available in the world.

Are you sure about that? I thought they are still available.

I was sure about it three years ago, but if you have something you'd like to share with the class, I'm all ears.

S and v are different kits. My wife got me the v70 kit for Christmas and they told her it was the last [v70 kit] in the us and came from California.

Did she buy it from someone on here named Kyle? He's the one who bought my set 3 years ago.

[DragosD]

I purchased my last summer, brand new from Netherlands.

No. Brand new from our volvo dealer in va.

I have switched everything excluding the center speaker from a c70 into a 850 sedan, sounds amazing no complaints at all. I am going to do the center speak just have not figured out how I am going to hide it. I found it to be a huge differance and was worth the change over. I bought the complete system (head unit amp and all the speakers from a coupe) for $100 bucks from a wrecker that did not know what they had.

But an S70 has bigger/better speakers than an 850 from the get go.

currently attempting to do this using my wrecked C... only thing that im stumped on is the 8" door woofers, did you make custom brackets for the door and cut the panel?
