Replace Dynaudio woofers?

To be totally honest the Xovers in over 90% of speakers under $15k are not thst good of quality. I know for not only have I owned a Audiostore for a decade 

but learn8ng over 20 years ago on parts quality in Loudspeakers as well as electronics ,only 25% or Less goes into the complete speaker including all packaging this is a fact the rest R&D overhead and markup. 
I just rebuilt a pretty respectable Xover itwas $1500  but the end result sounded better then a speaker at 2x thecost  , if they sent me the Xover then it’s less monies 

and I just upgrade the resistors and capacitors , BTW Dynaudio use parts from their area such as The Very good Jantzen inductors , the resistors , capacitors not that good . If you email me  in c o d e I can show you picture examples .

go to humble homemade hifi capacitor test ,the exceptional Tony Gee has this capacitor guide as a loose reference ,  different drivers sound better with different capacitors and resistors , I totally recommend WBT connectors .Dynaudio drivers have not changed that much. The build quality excellent. In my 3.4 contours I rebuilt including Cardas best -0 Crystal 6-9s copper  Litz wire  sounds better then their new 30 model it replaced by a good amount I spent $1600 just in parts .

I may be selling these later in the fall in rose wood cabinets each driver has its own dedicated chamber these weigh over 90 lbs each with boxes . 

That's not true, you can build a really good crossover for less then $100 in parts, the same way you can build quality speaker cables using 12 ga oxygen free copper for well under $100. Dynaudio has upped its game recently when it comes to name brand components in the crossovers, but even the older stuff was still high quality despite lacking some name pedigree.  The sound quality is in the design and execution of the crossover.  As long as the parts do what they are specced to do, it will sound good. 

Wow. I want to thank everyone so very much for all the amazing contributions. I was feeling pretty deflated, but now the mission is back on.

@perkadin  and @audioman58   Part of the reason I tried to remove the woofer so quickly was because there was an inkling (hope) it might be the crossover. I'll give the woofers another go (thank you @elliottbnewcombjr for the putty knife recommendation) and connect it to another speaker. 

Confession time: but it's probably the woofers: they blew during a party. I was young and stupid and let my friends keep turning up the volume (/cry). 

@timlub @jetter Thank you for the parts and service recommendations. I'll probably start looking into these immediately. And these "knock offs" are as good as OEM? Usually knock-offs of things aren't up to snuff, but I can imagine the it's different in the passionate world of hi-fi. 

Again, thank you everyone for your knowledge. I bought the Contours from Audiogon back in the day, and I'm happy to find it's still a great community after a 15 years absence. 

There is no chance you can build anything for $100  . I am speaking quality 

I have been dojng this for over 20 years , my standards are much higher 

having been into Audio for 40+ years, for example these white $2 resistors I use $30 each X4. Path audio ,much better detail ,clearer more open , if on a budget put in 12 watt mills resistors $12 each ,the inductors are Jantzen and good 

the white Mundorf are their lower mid grade Evo capacitors, Mundorfs Best quality are Black their Supreme line . Foil capacitors are better then sprayed conductors.

myself use the much more expensive Jantzen AlumenZ  capacitors ,

and Duelund tinned Copperfoil Bypass caps for the tweeters to complement the Jantzen ,I spent without the Upgraded Cardas wire $1300 just in parts .

that being said you can build a external Xover and use the Best Duelund capacitors 

depending on sizes 3x the monies, why don’t $50k speakers use top quality parts 

is all about saving $$ . I am just pointing out these from a 20 year+ point of expertise .  Just go to Humble homemade hifi capacitor test, the white Evo caps are respectable , and used by a lot of companies but rated roughly a 9

pThe best Duelund a 15,   Just get rid of the 4 -$2 resistors and put in all Path Audio resistors , and a .01 uf Duelund tinned Copper foil cap for the tweeter capacitor you will hear a solid increase in resolution and refinement for under $300.

I am just suggesting it’s your speaker I have been there done many combinations and still do for others ,all depending on budgets.

@xidnpnlss. I have seen the Dynavox drivers, they look fine. I have used the 6 1/2 inch original version of the HiVi. Totem used this driver in the original Forest, needed a bit of work, but turned out very well. I have seen a comparison of underhung woofers years ago, it compared a Morel, the HiVi and the Dyn. All 3 were 6 inch with 3 inch coils. The HiVi was the most preferred. If I can find it, I'll  post. The Dynavox look very good for such a low price, I know parts express has them, not sure about anywhere else. I hope this info helps you out, Tim
