    Which Tubes do you run in VRD's & why ?

    Mark,

     

    Do you have a pdf of the owner's manual?  I emailed Craig but no reply.  I really need to learn to bias these things. 

     

    I think that I have a few bad tubes too so I don't want to turn them on.  One of the 12 AU7XA tubes looks done, all of the silver at the top is missing.  Do these need to be matched?  I found a good deal on an untested single on ebay that might be worth rolling the dice if they don't need to be matched. 

     

    I always wonder why people sell them.  I now have seen several member say that they have had them two or three times.  I will store these if I stop using them as I will likely get the itch later on. 

     

    I don't know if it is outdated, (Probably) but Craig's site says there are only 28 pairs made. 

     

     

     

    I have the owners manual if you still need it. I can scan it in tomorrow if you do.

    Do you really need a center channel..

     

    lol !

    Yeah, I asked myself the same question and thought heck yes. Since this photo was taken I replaced the EAW with a klipsch KP301. Also added a couple Danley DTS 10’s to help fill in the bottom end :)

    I used the 14sa speakers briefly and returned them. I didn’t get much in the way of reflective sound with 11 foot ceilings. I’m guessing with your room configuration you won’t get much either. You can always give them a try and return them if they don’t work for you. 

    Show us your great photography thread!

    I know I discovered postimg from one of y'all at this thread when I maxed out what I could post through the site.

    Have you been able to work around the .org to .cc change?  Or maybe if I logged in to that site and uploaded them when posting that way it would work.

     Thanks johnJ. Here’s the same young fan a split second earlier.

    MCM 1900 Active or Passive?

    I've got some that I intend to go active so I'll ask a different way and maybe it will help Sprinter.

     

    For the:

    bass bins, would you put a low-pass on there with a crossover at 350

    Mid bass: high pass at 350 and low pass at 1,000

    MSM: high pass at 1,000 and low pass at 6,000

    MTM: high pass at 6,000

     

    ??

     

    Those high & low pass filters always get me tripped up

    Thanks Coytee, This explanation makes sense to me.

    You both are correct, using these specs for the original drivers in that 4-way system. You might also consider an active-passive crossover arrangement, maybe a passive between the MSM midrange and the MTM tweeter, to allow using fewer amplifiers.

    Thanks Khornukopia, I should have the hardware here in a couple of days and I'll give it a go.

    I hope you guys will cut me some slack for my lack of understanding on how to interpret crossover points and what they mean. I've read the data sheet for the MCM Grand and it's still not clear. It states in a 4 way configuration the crossover points are 350 hz, 1000 hz and 6000 hz. So does that mean that frequency ranges by component are:

    MWM: 40 - 350 hz

    MSSM: 350 - 1000 hz

    MSM 1000 - 6000 hz

    MTM everything above 6000 hz

     

    When setting the crossover points in the active network do I specify the starting and ending frequency for each unit to correspond to the list above?

     

    Thanks for taking the time to help.

    Roger, thanks for heads up re Chief Bonehead. . I'll drop him a note and see if he can get me close. I already dropped the coin on the Xilica so looks like i"m committed to that route. 

    I've been a huge Sprint Car fan since 1980. I'm no driver, but I have driven one (although slowly) felt plenty fast though. Your cousin drove in an era full of some of the all time greats, Dick Gaines, AJ, Jan Opperman, the list goes on. It was the route to indy back then.

     

    Chris, I hope I didn't bite off more than I can chew. It's going to take me a while to think through the steps you've given me to attain the proper time alignment. Seems complex, but I'll take it a step at a time. I really appreciate that you're taking the time to help me get there. I'll take any help or suggestions your willing to offer concerning the Xilica active crossover. I've read dozens of posts by you, Roger, Mark 1101 and others. Just enough to get me in trouble I suspect. 

     

    Khornukopia, Thanks for the data sheet. It's for a much newer system than mine, but maybe the specified time delays would get me close. I've had this sheet and I'm planning on using the crossover points it calls for. Unfortunately, no time delay information.
