Looking For Advice After Dumb Vandy Purchase
Good evening fellow enthusiasts. Looking for advice after just making a stupid purchasing error. I usually do good research before making any transaction but I fell in love hard and got burned.
Just paid for some used Vandersteen Quatro for a "decent" price but failed to notice the purchase dis not include the crossovers. I live in the boonies so dont have a dealer handy to maybe just make my gear work without the crossovers, and it seems now the cost of new ones are a staggering $1295.00. This was for sure not in my budget as I am needing a couple of other pieces to complete this puzzle. Worse yet...once I take delivery of the Quatros...I wont have a way to even give them the once over sound wise to make sure they sound fine.
Any advice? I am bummed beyond all get out at this moment.

You’re not dumb Brother. Sounds like you got burned and taken advantage of. Someone with knowledge of the quatros will chime in soon enough! Were the crossovers removed from the speakers? Or do they have external crossovers? Im ignorant to the quatros but this sounds confusing to me as well. Maybe there was a misunderstanding and that you’ll be just fine. Wait until delivery to really find out! |
Yes you must roll off bass via the external filter placed between the preamp and power amp!!! Running the mid bass unit in the Quattro without the filter will damage them! The Quattro and up in the Vandy line have an external filter that is adjustable for the input impedence of your amplifier to attain correct crossover frequency- Vandersteen is open and you can with consultation get some lower quality in line filters until you can get the M5HP. You can also modify or have modified with proper value components your power amp to effect the high pass function. Call factory !!!! |
What amp are you going to be using with the Quatro's? I've got five pair of SE inline filters of different values for a mint pair of 2W's I don't use anymore. Maybe we can work something out if you know what value you will need and I have that value. We can just go up one value to get the crossover point to the needed 100 hz. |
Thanks for the kind words everyone! I will be running an AR pre for now (can get the model number in the morning as its boxed up) and my monoblocks are Rouge M150s. The seller has been really nice, but in the end I should have done more research even though the ad is a tiny bit misleading. I will constsnt Johnny tomorrow. Jackd...maybe that is an option as well. I will let you know. Thanks everyone! |
Does anyone have a schematic of the crossover? I know I can figure one out from there. For 1200 dollars a pop.. I'd be looking, and building, my own. I'm sure there is a workaround and from the pic I saw.. AND better than factory.. Full of Wima caps, from what I saw...They are good stuff, BUT, there is a better cap for certain applications in a crossover, no doubt. The straps are inline filters too? If so... that's PA stuff... Lots of options there... I saw an XO called "Sirl's Killer" too. Seems to be an alternative. Danny at GR research... He may have something... Regards |
cost of new ones are a staggering $1295.00.https://img.usaudiomart.com/uploads/large/1141365-a2834c09-vandersteen-m5hp-crossover.jpg If you can find the schematic, you can clone one and save $1200 |
If the M-150's input impedance is 200kohm, a 0.008uF or 0.01uF cap
as a high pass filter
will work. http://www.learningaboutelectronics.com/Articles/High-pass-filter-calculator.php#answer1 |
So I am guessing you bought the Quattro cloth pair off of Audiogon that were advertised with an ARC integrated with modifications to insert the correct value caps to effect the high pass. They were advertised that way for a reason. the M5 does have bypassed WIMA, DBS battery, and normally AudioQuest fire or better pigtails and DIP switches so it works with just about any amplifier. Pretty sure you can’t diy and save $1,200... must be the new math. you should be calling Vandersteen and IMO modify the Rogues ( which btw sound fantastic w Quattro ) Richard can tell you what cap he uses in his $55k monoblocks lots of super high end gear w WIMA caps bypassed correctly - see Aesthetix, Brinkmann, etc Vandersteen since 1977 for a reason |
First, I don't think as a "dumb Vandy purchase", having owned 2C's as my entre to this crazy hobby and later Quatro's. They are really great speakers. If you only plan to use one amplifier, then you don't need the configurability that the Vandy crossovers offer, and a DIY mod to the amp input could be very cost effective. I honestly contemplated doing just that when I owned the Quatro's, mostly so I could optimize the capacitor selection for my system and tastes. I would think it incumbent upon any good Audiogoner to clearly spell out that the speakers do not come with the customary Vandy crossovers. If it wasn't positively declared by the Seller, well then, shame on him. That's less than ethical, in my book. |
“ I would never use any quality cap as a high-pass that is not biased! There is a reason coupling caps have gone bye bye unless they are biased in the circuit (typical of tube circuits). A coupling cap at line level never sees more voltage than the signal provides so the cap never forms properly in order to become transparent. The required high-pass is 100Hz. “ Richard Vandersteen

Yes, I got the cloth pair. The seller has been kind and he threw in some other stuff to help me offset the issue. It wasn't clearly stated but its more on me for my lack of due diligence. Its gonna be all good. Juat excited now. I just went ahead and ordered a new pair of crossovers. I didn't want to wait for a used pair and didn't want to riak a failed DIY project. I have heard Quatros before and I think the 150s will be a good match. |
I have Quatro woods with Aesthetix Atlas it has internal high pass and it works great but the M5-HP sound even better I had a Rogue Cronus before the Aesthetix powering my Quatros the guy at Rogue put in high pass filters in it for me that might be a possibility for you I would call John you need the high pass filters you will damage the speakers without them and you can download vandertones watch the video if you don't have DB meter turn all eleven pots to twelve o'clock will get you by but once you get them dailed in you're going to love them enjoy the music |
Thanks Tomstruck. I went ahead and just ordered new filters. I am sure I could have figured something else out but I didn't want to risk screwing up anything and didn't want to always wonder if I did something wrong. Ironically I am going to send my 150s to get upgraded to 180s but I dont wanna wait. Daddy needs tunes now. |
@troutki50 I think the Quattros are the same HP filters as my Model 5As. If so I will make you a pair for a little cost plus the parts. I built mine and compared them to the Vandersteen and you could not tell the difference and actually I preferred the ones I built since we used better parts. Send me a message and I will build you a pair. The Jupiter capacitors are OK but I prefer V-Caps over the Jupiter capacitors but you don’t really need either to make a better HP filter as Vandersteen uses pretty cheap resistors and capacitors. I think the parts were under $100 plus the eBay aluminum chassis boxes were not that much. Let me know. Happy Listening. |
Do some prep work ahead of Quattro and M5 arrival: download the manual do the math based speaker placement to see approximately what works in your room. download Vandertones or hopefully seller provided you with Vandertones CD you need the Radio Shack analog SPL meter ( not the digital ) e bay about $40 |
For reference I compared the Ayre to the older Ayre QB 9, the PS Audio, can’t remember which one, it was around $1500 and an older Wadia 27ix. I found the Codex to be better in every way. Also, I’ve heard too many stories about equipment breaking and either not being able to be repaired or having to send it out of the country to be repaired to take a chance on a non US brand. Good Lick in your hunt. I’m sure you will love the Quatro’s. |
Do not despair! If you want to use a passive crossover, send me the crossover frequencies you wish to use and all the data you can find on the driver's impedances and I will send you a schematic, parts list and estimated parts price from Parts Express, Madisound, and Parts ConneXion. It is not difficult to build a decent sounding one. There is no sense in using anything less than high quality parts with your speakers. So I'll suggest Mundorf capacitors & heavy wire coils. You may be able to get the actual schematic from Vandersteen and work from there. I'd like to suggest an electronic crossover (miniDSP) and one amp per driver. Good amps (65 wpc) are buildable for roughly $100/channel/frequency band and allow easy adjustment of each driver's level (why use resistors in a crossover to waste power making things hot?). Also, connecting an amp directly to the driver (speaker unit) allows you to take full advantage of an amp's ability to correct and control the motion of the speaker's moving parts. Keep Smiling! This is a solvable problem. |
