Subwoofer Eq Suggestions

[Warpdrv]

Your on the right track avaserfi....

Sometimes its just one thing at a time... Glad to see you are getting into bass traps, thats awesome... Don't let those pushy bastar@s drain your wallet to quickly.

What are you looking at for BFD's? I got a great deal on my Velodyne SMS-1, if your interested in that unit, I am able to pass on the info if you want...

I paid $470.00 shipped, NEW...

if you get the sms-1, you won't have to go to your PC everytime to hit the sweep. the sweeps on the sms-1 are continuous ... puuuuuuuuuuuuoooooooot!

After talking to SVS about getting the other woofer they recommended doing an EQ first then picking up another sub. Since they say that I believe them. After treatments its a BFD .

It would be nice to do measurements as is, then after each step.

"Those" pushy bastar@s draining your wallet? LOL.

(Careful, avaserfi....these ADD people are everywhere!)

Thats my plan . I have a frequency response graph of after the crawl test and I have one of after playing with all the settings. Next posted will be after acoustic treatments and finally after an EQ is added. It will be nice to see and of course hear all the changes made

Im going to answer your PM here avaserfi.... that way others can chime in to help...

I have heard great things about the SMS-1 and was looking at them at first but the price is rather prohibitive comparing to the BFD. How well do you like your SMS-1? Have you had experience with the BFD, if so would you still take the SMS-1 over it even with the price difference? Lastly, I have heard that a problem with the SMS-1 is that it tried to correct not only peaks but dips in the frequency response. Have you ran into that problem?

I love my SMS-1, yes it is a bit more expensive, and if your a hands on guy you can figure out the BFD pretty easily from what I have read on the BFD forum. I don't mind spending the extra $$ for something that is Plug 'n Play.
Velodyne has a good reputation and the SMS-1 is a really nice, solution. I pretty much have it laid out as a set it and forget it item.. the only thing I change is the volume of the Subwoofer output from time to time.. and it has multiple memories that you can switch between.

The SMS has a ton of adjustments, you can read the outlaw manual, which will help you understand most of it... http://pdf.outlawaudio.com/outlaw/docs/sms1guide.pdf

There is both the Automatic setup, or the Manual setup... Like any reciever the algorithms aren't perfect, so I opted to do all the setup myself. Im not sure who would use the Auto setup, as I am a tweaker... so I fiddle with the dam thang to get the results I was after. Here is an older screenshot before I gave my room a house curve. But its pretty much ruler flat. Its a very nice tool to add to your system. Seriously tightened up the bass in my room for that added dose of slam to your movies and music. http://s34.photobucket.com/albums/d109/Warpdrv/HT-Great Room/?action=view&current=HTPics014.jpg

You can accomplish pretty much the same results with a BFD for less $$ but more effort. Once you get it setup, then you can just forget it as well...
Don't forget that you need a Mic, a Preamp for that mic, unless you get that digital SPL meter. And also you have to buy an external USB sound card if your using your laptop. So the cost of the BFD depending on which one you get is quite a bit less then 1/2..
Oh and don't forget that the SMS-1 is much prettier...


NOW, I ask you guys a question... do you think I should go for bass traps, or is my response clean enough that I shouldn't worry about it..?

 

[Warpdrv]

"Those" pushy bastar@s draining your wallet? LOL.

(Careful, avaserfi....these ADD people are everywhere!)

HEHEHHEH I thought you'd like that...

Don't worry aveserfi... your just next in line... they got to me before you...
which pretty much put me into the position of new recruit, so now its my job to pass along the chain of command...

But seriously, everyone here is only here to help, with a smile on our faces, as we are all after that same un-obtainable audio nirvana... I love music and movies and love to help people, so I hope to be of some help...

If anyone is ever in milwaukee, they are more then welcome in my house, I supply the Booze and the Food... Just ask Babelfish... He came up from Chicago...

 

[mike c]

I'm going to answer part of the pm as well. regarding the peaks and dips, that's only with auto-eq ... surely you don't buy a nice car and let a driver drive would you?

regarding the BFD vs. SMS-1 ... I never got to the BFD part because when I read the manual (or FAQ for BFD) ... I figured that the extra dough I'd have to cough up for the sms-1 should be well worth it. alas, I have two sms-1's on order. (it's still stuck in customs)

Well I have the money for a SMS-1 that wouldn't be a problem. My ability to save well and working upto 80 hours a week and scholarships rock my world I end up giving myself about 240 a month I can spend on whatever. Since I am not a fan of the bars, I stay in and drink with friends for fractions of the price , I tend to drain this money into my hobbies hometheater and cooking.

Warp I already got the soundcard anyways I needed it to use Room EQ Wizard and it was 20 bucks shipped so thats not a big deal. The basstraps might actually help smooth it out a bit but I don't know what treatments you already have. You might look into getting/building some treatments that cover high and low frequencies to flatten your overall curve.

In the end I have some thinking to do. Warp could you send me that source just incase I decide on it?

Ohh and if anyone is ever coming through Iowa for some stupid reason my place has an extra bed and like I said I love to cook so just give me a heads up.

I could go for a good salmon steak and a small loan...say $5K.

Hahaha you come into town I can cover the Salmon steak like a pro the loan well...thats another story.

On the way...

avaserfi, Maybe you would like to inform the good people on this forum about your recent decision.....

Is your graph 1/3 octave? Much more interesting at 1/6 or each cycle. Yes, lots more work but those in-between stuff is important and can be interesting that may need attention.

If you're asking about this post, the former appears to be a fully continuous REW sweep, and the latter is the same plot, but with 1/3 octave smoothing applied.

 

[Dolby CP-200]

1/3 octave EQ is the way to do it.

I reorganized my photobucket without realizing it would remove the pic. This is the full range sweep here:

Due to Warpdrv's insistence I contacted the source he got his SMS from and purchased one of my own. It should be in after about a week and a half. Once that comes I should already have my panels up so I will post a graph of post panels and then another of panels and SMS. If I have enough time I might even take the panels off to see what I can do with the SMS without any treatments for fun.

Again, I am broke but its for a good cause

Also, I plan on doing a full run equalization not just 1/3 octave. If I am going to do it I should do it right .

 

[Davemcc]

Very nice. Congratulations. I look forward to seeing your results.

Yes, thanks, too much data, overloaded.

 

[avaserfi]

Very nice. Congratulations. I look forward to seeing your results.

I will be going home on Wednesday and will be making the treatments sometime when I am home. Originally the plan was make them, but my father has a friend who works with rigid fiberglass and basically gave me some OC705 2" for free so I can't say no, as if I would. I will be getting back Sunday at some point and plan to install the panels soon after, probably between Monday and Wednesday. So expect results part 1 in about two weeks max if everything goes right. The SMS results will follow soon after.

edit: I will also try to make an article of sorts as a DIY primer to panel building as I figure it might help some members especially since I plan on making a few types of absorbers: 4 inch thick bass traps, 2 inch thick absorbers for early/late reflections and lastly 2 inch triangular traps to fit in the tri-point where the ceiling meets two walls.
