Vandersteen 7 and room treatment


My circumstances have changed in an unexpected way allowing purchase of a well, but gently, used pair of original 7's. (Also SOTA Sapphire with Ortophon Cadenza Blue in house and Supratek Cortese LCR on its way) I have a dedicated 15 x 20 room full of 14 various GIK traps and panels. Will using the EQ, contour and level settings allow me to get rid of some/all of the room treatment? Should I attempt initial setup with all/some of the panels in or out of the room? Anything to give me a head start short of trial and error. Nearest dealer is 400 miles away so on my own

Personally I would start with all the panels in place, as you already know the room.
Then remove panels one by one.

Measurements with REW might be able to show a time domain comb, and keeping the early reflections low is usually better for imaging.

Whatever method you use will be a lot of trial and error, or trial and measurements along with listening.

It could make a good study though.

Nioce!
That is good find.

400 miles from where?
If it were a hundred miles more, it could possibly made a good song lyric?

There is a vandersteen forum.
Many would say just get their vandertunes and adjust the sub settings, using the manual.

A limited few might suggest something like a MiniDSP Flex, or a Lyngdorf TDAI amp.

But if these 7s have the 11 pots that do the sub bands, maybe start there?

 

…but it sounds like you want to use those pots and then get rid of wall treatments?

Thank you holmz. Albuquerque.

Just visited my ex FiL about 6 week ago, north of I40 and West of Coor’s road.
Got a load of chile and pasole from “The Fruit Basket”.

 

So that “80% of the 500 miles”, is north through Taos or Tierra Amaria?


(I did that drive one early morning out of TA, and spilled coffee on my new blue jeans. The dye in the new jeans produced a distressing colour on underwear.)

I have pair in woodshop 10 ft ceiling. Have drill press and radial saw behind lathe on left side. Right side have lumber rack. Sound very nice. Fly the richard out.

 

Yeah… we would need to fly him as he ain’t Irish, and it is likely 2x 500 miles from Hanford.

Better than the speakers in a treated room looking out of ABQ, would be in front of a window in the more alpines or north NM… 😎

 

I’m tempted to clear the room of all the treatment and see what kind of sound I can get just by tuning the speakers.

The treatments that do bass are usually thick, or they are Helmholz resonators, bass traps, etc.

The thinner treatments on walls usually kick in at 100 or 200 Hz on up. So one either using things like the Vandy subs with tuning pots, or a DSP based like MiniDSP or Lyngdorf for the < 200 Hz region.

And using something like REW to get decay times and see what the modes are can help to try and get the treatments to address the problems. And also seeing the early reflection peaks,

Usually when one talks about whether active or passive methods are superior it is black-n-white argument. The best systems usually use passive methods, and layer in some active controls to get the rest of the way.


An example would be active cancellation in a headphone.
We can reduce the SPL by 15-25 dB passively with earmuffs.
If we tried to do that at 20dB actively we would need to be within 1% (or maybe it is 3% if we are doing 10log10 versus 20log10). That gets hard to do.
If we are within 10%, then we can get 10dB pretty easily, and that 10dB layers on top of the 15-25dB of the passive.

 

Basically I think that you will want some of your treatments to stay, and corner treatments may change to bass treatments. But some measurements might help to work through it. And I doubt that the treatments are helping a lot in the bass, but they might.

 

My son and I will be driving up through Tierra Amarilla to retrieve the speakers next week.

FYI: The donut munchers in Southern Co have little tolerance for speeds over the posted limit.

I’ve spent a bit of time up around TA.

And the ex-FiL and I did a drive around Rio Rancho ~3 months ago.
