Vandersteen Sub woofers v Rythmik Subs

I, too, have an issue with my McCormack DNA-1 monoblocks, in that they have pretty low impedance-like yours.
Using balanced, I can only get to 22Kohms. And, I think going lower would be beneficial. So, either I go to unbalanced or have SMc Audio redo their work. I am leaving it for a time when I can reconfigure my wiring.
Until then, I still have the Atma MA-1's and Ayre MXR's, so I am in no hurry. (It's nice to have options).

MXR as spares..... :-)

first time I heard Model 7 was at RV’s house.... running on MXR...

( his amp was in development )

give that some thought.....

bstatmeister: "Honestly I would rather buy an extra sub than a cross over - at least to start off with...lol"

    I have no experience with the Vandersteen crossovers discussed but I'm fairly certain that having 2 subs rather than just a single sub in your system, provided both subs are properly positioned, would result in a more significant and obvious overall system performance improvement than utilizing a high quality crossover would.  You could always add the crossover subsequently if you thought there was a need.

Yeah, before the x-overs, would probably upgrade to the latest model 2 after I buy the 2 subs (my model 2Cs are pretty old at this point and will need to be put out to pasture in the next 5 years or so. I think at some point I will want the HP-5s, just trying to improve the most noticable things first.

" @noble100 and others interested in room acoustics: which other fora are you active in?

I'm interested in discussing and posting some measurements (which Agon doesn't allow) and would live to engage others who share that interest.

Cheers!"

Hello lewinskih01,

     Sorry for the delayed response, I just noticed your question today.
   
     First, by your 'Cheers!' sign-off, I inferred that you're an English brother. 
     Unfortunately, it appears we Americans often prefer the siimplest form of things both grammatically and presidentially. We typically employ 'forums' as the plural of 'forum' and only employ the original Latin 'fora' as the plural form when  we're referring to  the marketplaces or public places of an ancient  Roman city forming the center of judicial and public business.
     I realize there are other variances between English and American grammar.  For example, the majority of Americans describe our current president as an 'idiot' or 'dope' depending on region, while the majority of Englishmen likely describe him as a 'wanker'.
 To answer your question, however, I mainly participate on this forum for audio discussions but would recommend other forums, such as Audio Circle and DIY Audio, for subjects such as room acoustics discussed in more detail and scientifically. I participated and learned a lot about class D amps and in-room bass response on those fora. Doing a Google search on "room acoustics" would also prove useful.

Cheers!
