Did you try the 10k setting?
|
@audioconnection I am starting to lose it. Tried 80Hz settings recommended, 1 up and 1 down, and I get no sound out of 2Wqs. Upped efficiency control to 85 dB, no difference. Burned a CD of Vandertones, but my amp did NOT like being touched by multimeter pins.... triggered protection circuit repeatedly.
I set the M5-HPs back to the 20k settings and will try letting them and the amp burn in for a while.
FYI, I took the M5=HPs and 2Wqs out of the chain altogether and got much better low end from my speakers run full range. I really miss what the 2Wqs used to do. :-/

Yes. Richard's personality is very colorful! |
@mr_m ,
We aren't putting words in you mouth/text in your post.
We just recognize Mr. V's personality.

Please. Don't take what I said the wrong way. I have talked to Mr. V. a few times and for the most part, he was very pleasant. We had this very discussion about the 2Wq sub I had just purchased and he got just a bit agitated about how I was going about integrating his sub with my amp. He asked me if I had read the owner's manual and I said YES. Twice! All turned out well after that. |
@gdnrbob +1 "brusque" is the perfect adjective to describe Mr. V.

@bondmanp
When Johnny said to measure the voltage, he meant at the main amplifier not the sub.
And, yes, the settings for the M5 should be from the list on Vandersteen's website and not the crossover box. Those, as hifiman pointed out are for the Quatro and above.
Mr. V. can be brusque at times, but never angry. He's too classy.

@mr_m - Yup, I’ve heard. But every time I’ve interacted with him, both by phone and in person (about half a dozen times), he has been nothing but pleasant and patient.
I left the screws off the chassis of the M5-HPs, so when I have the time, I will play around with the 10k setting for 80Hz. |
Bondmanp. No. you're not living in sin. You would make Richard Vandersteen very angry. You wouldn't like him when he's angry...lol |
@mr_m@hifiman5 Ah, that makes sense. The 5 series speakers cross over at 100Hz. So, I guess for now, I am living in sin. |
|
I believe the sticker on M5-HP has settings to accomplish a 100hz crossover point, whereas the settings page for the 2W series subs is for a 80hz crossover point. Correct? |
The following question and answer is from "Ask Richard" on the Vandersteen website. Roger (8/12/15): HELLO, I have a couple w2 s paired with 3Asig and a set of M5-HP filters . My questions are, are the stickers on the covers accurate for use with the 3as and is "open" on the dip switches the same as "on"? Thanks Roger HELLO ROGER, THE STICKER ON THE COVER OF THE M5-HP IS ACCURATE FOR A 100Hz CROSSOVER (MODEL SEVEN, 5A CARBON AND QUATRO WOOD CT SPEAKERS). WHEN USING THE M5-HP(B) HIGH-PASS WITH THE 2W OR 2WQ SUBWOOFER (80Hz CROSSOVER) YOU WOULD USE ONE SETTING LOWER. OPEN IS OFF. What Richard probably should have been clearer on is that when using the M5-HP with the subwoofers to use the settings as shown on the chart as displayed on the website. As he did say, the sticker settings are for Model 7, 5A Carbon and Quatro Wood speakers. |
@hifiman5 - Yup, I know, I live La Vida Loca. But the Vandy web site does specifically say "when using the M5-HP with 2W series subwoofers, the sticker on the chassis should be ignored. Set the switches according to the applicable chart below." Unless what is meant is the V2W, I don't understand this. Why would "2W series" exclude the 2Wq? |
@bondmanp Surprised you would be so cavalier as to use the setting on the M5-HP sticker! 😈 As I posted previously, you should realize ample bass and good integration with your main speakers by setting the crossover to 10k. You can then adjust the efficiency dial on the 2wq to tweak the subwoofer output.🎼 |
Thanks, all! Before I read your helpful suggestions, I decided to live on the edge and try the dip switch settings on the M5-HP cover (as opposed to the Vandy web site). Using the 20k ohm setting, my bass has been restored to levels very similar to what I had prior to the amp upgrade. Now, shortly before the amp upgrade, I installed new cables between my DAC and pre. While they were overall a big improvement, the bass levels seem a bit reduced. So, follow-up question: If I want to goose the bass a little bit, am I better off monkeying around with the 10k ohm settings on the M5-HP or just dialing back the efficiency knob on the 2Wqs a bit? I would hate to fool around with the Q setting - I love the tight bass I get with the current settings.
@audioconnection Johnny - when you say to connect the voltmeter to the "amp's" speaker posts, are you referring to the main amplifier or the plate amps on the 2Wqs? Thanks! |
Sounds like 10 K should work but confirm it .
If you go to Vandersteen website under resources download the Vandertones make a CD or file turn preamp volume down.
track 27 is 1000 hz track 31 is 80 HZ get a Voltmeter set to AC Volts looks like a sideways s snake and connect probes clipped to amps speaker posts Red is Plus Black is Minus
Play track 27 and slowly raise preamps Volume up till Volt meter says 1 V AC then play track 31 if your dips are set right it should now read.707
once you get it set a few days of run in should sound great again.

Correction. I see his amp is now at 22k. Was told you can experiment one or two steps down. Using caution of course... |
The 10k setting for Bondmanp's amp would be the one step down from his 20k input imp. Just as Hifiman5 stated. That should restore the bass. One has to be careful not to go to low below the input imp. as this can damage the subs internal amplifier. This is according to Richard V. |
+1 hifiman.
If you find the bass lacking, just move down a step. The M5-HP settings list is on the Vandersteen site.
And, you can always call Johnny Rutan at audioconnection. He is only second to Mr. V himself.

@bondmanp Unbelievable coincidence. I just sent my primary away for significant upgrades and pulled out my 22k input impedance Adcom GFA-555 back-up amp. I have two 2wq subs. paired to my Treo CTs. I would suggest setting the crossover to 10k. That means you want switches 2,4,7 ON.
When I have my 100k main amp in system I have the crossover set to 75k. Integrates beautifully.
Please try 10k I really hope it works well for you!

My suggestion is to try to get Johnny Rutan to chime in! (@audioconnection) |
