Happy New Year All!
I guess this question could go in several different catagories but here it is.
As I read various posts, it seems like a sub in a 2 ch system it taboo.
Excuse me for my ignorance, but why is this?
----Or is it that if one builds a quality 2 ch system that the main speakers should produce all the bass one needs?
just wondering????

You're really short changing yourself by "not" adding a good sub or two for your "complete" 2 channel enjoyment.

It seems that there are the purists that will insist that a sub is taboo and then there are those that feel that a sub is still necessary to obtain all the needed frequencies. Then there are those who could care less and just have a sub to shake the house, regardless of the sound quality.
I have and can appreciate both sides of the fence. It all boils down to personal preference. Most of the outstanding 2 channel systems that I have run across in my travels have had no sub and full range mains. Only one or two outstanding systems have had a properly integrated sub to where you did not even know the sub was playing or on. With less than stellar room conditions, gear or speakers a sub can add depth, better dimension and in some cases better imaging to a rig.
Going back to your quote above? If it is a quality, well thought out and assembled 2 channel rig then you will already have all that and slightly more already present.~ In search of accurate reproduction of music. Real sound is my reference and while perfection may not be attainable? If I chase it, I might just catch excellence. ~ -
Since my audio goal is to hear all the information that is present on the cd, I've always found a well integrated sub helpful. Sealed is even better. Now this has to be excuted right or it will sound worse and you would be better off without a sub.

I have never been happy with the way a sub integrates into my system. I imaging some of that is the room itself being the issue. I am much happier with "so called" full-range speakers, in that they give me all of the bass that I require, and go plenty low for my tastes; and there's no issue with integration.Speakers: Polk LSi15

Exactly right. The key is to achieve proper integration with the mains. This has a lot to do with the quality of the sub & even more to do with the room. I fully understand when guys say that they don't like adding the sub because they could never get things to jell.

My room is exactly the opposite. A sub is absolutely necessary to correct for a massive 20dB canyon :eek: between 45hz and 75hz.
Not only that, I like to feel a bit more bass too. Now that I am used to sub in my 2-channel, I doubt I could go without it. Plus it's nice for the movies too.
All it takes is some time to sit down and go through all the steps (possibly several times!) to integrate the sub very cleanly. Maybe these SRS's are more sub-friendly than some other mains.

Don't try it with the PSW10, I did its a POS. I love my Polk, but i have no love for the PSW10. It sounds like ****.
With that said over the past few months I have heard a lot different gear and speaker configs. Subs are needed plain and simple.
The best systems I have ever heard was some High end Magnepans and Paradigm Signatures on thousands of dollars worth of tube gear. In both cases I lessoned to them with a sub on and off. In both cases (the Mangnepans more so then the paradigms) the system just was not the same and a lot of information was lost with out a sub.
The only speakers I have heard that maybe could get along with out a sub where some definitive technology speakers. I think they where called super towers or something like that. However even they could not put out enough slam for things like kick drums nor could they really hit the low string bass like a good sub could. Honestly when it comes to reproducing sound, if you can't move as much air as the real life counter parts can (kick drums, deep string bass, the roar of a T-rex in jurassic park) the speakers are not going to sound like the real life counter parts. And I don't know of a pair of speakers that by themselves can move that much air, maybe some on this forum that are more blessed then me might be able to name a few but i can't.

You shouldn't need a sub with the SRS's. Just my opinion. They have plenty low end for two channel -

I am mostly in the no sub for 2 channel camp,but If you do want a sub,I would suggest dual subs. I see most of you who like the the subs for 2 channel have 2 of them, and I understand that, thats what I would do.

The key was a stereo pair. I tried just one and no matter what I did or tried, the sub was still obvious. Once I installed the second one, the bass snapped into focus. Now, if the double bass is on the hard left, with a sub over there it is believable instead of the right sub trying to steer the bass to the left.
I'm not a basshead trying to knock the drywall down I could do that if I choose to but it sounds very fake. Once well integrated, everything from mid bass on up has much greater authority and weight. Something I could not achieve with only one sub.

Hey Gordon, I take it you're still thoroughly enjoying those Mac 501's!!! I'm still working on that MC 402 here though.
I think a lot of guys simply think that adding a sub (or better yet two) is all about filling in the low bottom end. Man, they couldn't be more wrong...a quality, well integrated sub really elevates the whole listening experience. Of course they're there for the bottom end when needed, but it's the other attributes that simply have to be heard & felt to fully understand. Your main speakers (regardless of what they are) are now fully liberated & now perform in ways you never heard them attain before.

Are you guys using external crossovers?
How are you blending the crossover point between the sub and your mains?
I have been playing around with a very basic set up using the speaker wire through the sub to the speakers but it seems to be ruining my imaging. Without the sub the little Insignia's image very well with a little bass, I add the sub and I am now listening to 2 speakers with a lot more bass.

In a nutshell, what it does is takes the sub and blends it with the mains. At the same time it blends both with the room, calibrated precisely to your sweet spot. The adjustments are virtually infinite and very precise to adjust to your liking. Here's aPDF made by Outlaw audio that explains all that the SMS-1 will do for you....
http://pdf.outlawaudio.com/outlaw/docs/sms1guide.pdf
I currently am running the SMS-1 with the VMPS Larger and whatever amp I choose. I found the best blend was with [believe it or not] a Carver M1.0t MKII. Even Bob Carver himself asked how I got the sub to blend so well. Many a folk has asked the same thing with some heavy hitters asking me if the sub was even on. It was, they just didn't notice it was on because of the integration between the sub and the mains and both to the room's acoustics.~ In search of accurate reproduction of music. Real sound is my reference and while perfection may not be attainable? If I chase it, I might just catch excellence. ~ -
One more thing, I finally received a set of [very close too] full range speakers. They are the Tyler Linbrook Signature series speakers and I don't know as of late as to whether or not I will be keeping the sub. The speakers go down to 25Hz but I would swear that they dig lower at reference levels.
More time and experimentation will answer my own question on whether to keep it in the loop or not.~ In search of accurate reproduction of music. Real sound is my reference and while perfection may not be attainable? If I chase it, I might just catch excellence. ~ -

Like I said, due to room dynaimcs, the SRS's alone have a 20dB canyon right in the middle of the midd-bass. Only way to fix that is a subwoofer or a new room and I can't afford a new room.

Scott
Scott,
I'm not running any crossovers except what's on the SVS. Despite my canyon in the mid-bass, the SRS's, from 45hz down, perform strongly and when coupled with SVS and the fact that human hearing is not linear, especially in those low octaves, there's no way I would want to give up the performance of the SRS's.
I am running the SVS crossover right at 80hz since the SRS's canyon doesn't recover until about 75hz, I need a little blending space. I'll see if I can post my response chart from Excel showing both curves, without and without the sub.

I was in the same spot you are in and recently decided to let my 15" velodyne sub go and let the Linbrooks do it all. It was better with the sub, no doubt, but I had to sell it for financial reasons (upgraded amp). Dual subs would be fun to try in the future. -
WOW!
Thanks for all the input. I currently have RTi8's and onkyo 507. My original plan was to do a 5.1 system, but now I am considering a surround bar for the LCD.
I am really new to all this so I guess I need to hear some different set ups.

Thanks Tom and Wes for your responses.
I am currently just playing around with a set up I may use for a fundraiser at the end of February.
But what this has made me realize is that I am missing the very bottom end and some weight that is not present with my SDA 2B's.
Back when Polk was circulating the micro-pro 1000 (IIRC) I did hook it up to my main rig and I liked the weight but for some reason using a one channel on my integrateds pre-out RCA to the RCA input on the sub caused my SDA to disappear. Tom I would also consider my 2B's to be nearly full range.
I think the passive radiator also contributes to the complication of integrating a sub(s).
Sorry for the threadjack.

Scott,
Try running a stereo pair of RCA's to the sub's input instead of one channel. I have never tried a single channel, but with a stereo input my SDA is strong.

I hooked it up with 2 RCA interconnects and my SDA was still there and it added that bottom octave that I just was not getting, Although not as drmatic as I thought it would be. After a little fiddling it sounded pretty good for less than 5 minutes of work.
I am sure if I had one of those fancy SMS-1's i could have made it even better.
My biggest question is how do you handle the difference between the Mid woofer and the PR when you use a sub?

Not sure how to answer that question. I think the biggest thing is to take the time with an Excel spreadsheet with the frequency corrections, your Rat Shack SPL meter, and a 1/3 octave bass tone CD and play with the crossover frequency and phasing.
It may take several hours but the effort is worth it.
