+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. B |
@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. B |
@mr_m , We aren't putting words in you mouth/text in your post. We just recognize Mr. V's personality.

Yup, 2012 batteries are probably kaput. Don't they have the expiration year written on them? All the ones I have, have a date written in magic marker, so no question when to replace. B |
@bondmanp , It sounds like you are doing this the right way. I, too, had my amps worked on and when they came back, I wasn't informed that they had lowered the impedance considerably (like 100K to 20K), so, of course, the M5-HP's needed to be adjusted. Unfortunately, they only go to 22K ohms in balanced. The bass is just a teeny bit shy, but acceptable. In conversation with Johnny, it seems Mr. V. doesn't want to go to any lower setting-I forget why. If the batteries were near the end, and you disconnected them for a prolonged period, then they possibly were drained by not having another source (your amp) to keep the crossovers charged. Just thinkin'... B

Hmm, do you think it is worth it? Will the repair cost that much? Knowing how these things play out, I bet UPS will blame the amp builder for not packaging correctly. Though I never had an issue of a box being so roughly treated that the internals were knocked apart. Was it double boxed? When I sent my amps to SMc Audio, Pat recommended that I double box and put lots of extra packing to absorb a shock should it drop 5 feet.-Which is the worst case scenario if your box is the first being deposited into an airplane cargo hold with no other boxes to cushion the blow. B |
@bondmanp That's good to hear. Was the packaging damaged on the amps when you received them?-Like somebody dropped it? If you don't go the double box route, at least have him get some triple wall cardboard boxes. Those Home Depot double wall boxes are just too thin. Also, if the amps are unwieldy (heavy/large), have him add strapping and/or corner bracing. When manufacturers put 100lb items in thin cardboard, and expect UPS to move them gently, that is when problems happen. After all, if you are carrying boxes all day, the last thing you want is an unwieldy box. That is why I like strapping. It give the delivery man a way to hold onto the box. B |
Glad to hear that the problem has been isolated. I would be interested in hearing what Mr. V. finds in those M5-HP's. I didn't think there was anything that could go wrong with them. Bob |
@drew_k , I think Johnny would be the best person to ask. You can PM him if you want. Bob |
I would do as Mr. V. said, and check to be sure the impedance is acceptable for the crossovers. The only other Agon'er I would contact would be Ralph Karsten (atmasphere). I am sure he would know if there will be issues with impedance. (And, I know he is working on a Class D amp, as well). Bob |

Oh, noo. I meant I did agree with you. B |
@bailyhill, Nice post. And, I agree that Johnny R is one of the best dealers, as well as the Vandy method of integration. But, I think you should start a new thread. as this is more of a Sub 3 than M5 crossover issue. I would be interested in hearing your Apogee's. I haven't been able to hear them, but know of their performance, and unfortunately, don't have the room to give them. But, hey, knowledge is power.😉
I, too, will be ordering the Sub 3's from Johnny in the, hopefully, near future. I also hope he will come to my home and set them up. Bob |
