LOL What???

Those are 5.25" mid-rage drivers.

 

[freshazzburu]

uh, the second thing in the list actually has two subwoofers in it... Am I missing something? Bass effects should work with this setup, no?

Yes, you're missing a subwoofer. The second thing on your list is a center channel with midrange woofers that hand 55Hz on up. A decent subwoofer will handle a frequency of at least 25Hz - 100Hz (Although the LPF should be set to cut it off a little less than that if the mid range are decent enough).

So no, it is still a 5.0 system. The 0.1 represents a sub, which is why some systems are marked as 5.2 (because they utilize 2 dedicated subs).

So, um... what spec are you going off of to say that i'm 20hz off from being "5.1"? (yeah, I think you're full of it, but if there actually is some spec you're working off of please do share it with us) And uh... consumer-grade subwoofers rated for 25hz? Don't most consumer options bottom out at 30hz? You could certainly get some nice infra woofers rated for 18-95hz... but get real man that's not consumer grade and you don't need an infra woofer system to get surround sound.

So with "only" my 15" Bag End subwoofer rated for 50Hz at the lowest I'm not experiencing true 5.1 surround sound? 🙁 http://www.bagend.com/bagend/s15-d.htm Should I trade it for a Z5500? :roll:

Audio isn't my strongest area of expertise and if you've got some data to back up that smack talk feel free to let loose but until then you can cut the elitist audiophile shtick (FFS I can't really even hear anything below 50hz, at least not over the sound of the house shaking and most other people can't either). You could have just plainly stated that the system I put together was only rated for 55hz and the Z5500 is rated for 33Hz and that human hearing is generally considered to range down to 20hz so the difference would be noticeable and that you would advise spending another ~$150 or more to get a better sub but saying that 55hz isn't even a sub without providing any data as to what the hell you're talking about is a little silly and not very helpful.

I have various "subs" rated for 40, 50, and 60hz but I still love playing that bass test track (starts at 320Hz and goes to 10hz in 10hz increments... neighbors don't seem to like that one much but I think it's pretty awesome :twisted: ).

I think your a slight bit confused. Just because a driver is 15" doesn't mean its a subwoofer. 50-4kHz looks like midrange to me...

Hell, Rythmic sells a 12" that is linear down to 10Hz... There are 6.5" drivers very capable of 30Hz reproduction...

A dedicated subwoofer isn't always needed to reach 30Hz, or even 20Hz. There are full range speakers capable of doing that.

My main speakers are capable of playing down to 50Hz accurately. I find that more appealing than a boom box that can play down to 30Hz.

 

[astrallite]

With subwoofers, the important thing is more the overall mass and volume of the driver rather than just pure surface mass.

There's a big difference between a 10" Logitech subwoofer driver and a 10" SVS driver--the SVS driver is probably 4-5 times bigger.

 

[Clob]

Meaning it sweeps much more air (cone area), and the actual driver is larger, and heavyer.

 

[davidinsarasota]

Undoubtedly so. But even the 10" Logitech is overkill by a factor of about 4. So what is the advantage to an even more preponderous bass?

Correct me if I'm wrong, but aren't consumer products those which are marketed to the mass market? So you're saying one must buy industry standard equipment to obtain a decent sub that is capable of sub 30Hz frequencies? Even some entry level companies provide subs capable of 25Hz +/- 3dB. Now want to talk mainstream? Here: $400 SVS 10" passive sub/box capable of 20Hz - 100Hz +/- 3dB SVS 10" Sub with specs

That thing is basically a very big midrange. I never said it had to be big to be considered a subwoofer. All I said was what you provided was a 5.0 system and not a 5.1 system because the lack of a dedicated subwoofer. I was only trying to be politically correct, but obviously it was interpreted as offensive, which was not my intension, so for that I apologize.[/quote]

I only speak what I know and ask what i don't know.

... You could have just plainly stated that the system I put together was only rated for 55hz and the Z5500 is rated for 33Hz and that human hearing is generally considered to range down to 20hz so the difference would be noticeable and that you would advise spending another ~$150 or more to get a better sub but saying that 55hz isn't even a sub without providing any data as to what the hell you're talking about is a little silly and not very helpful.

My intention was to get across the fact that it was not a 5.1 system as you had advertised and it was actually a 5.0 system. You stated a post later that the center channel you linked was what made it 5.1 because it handled 55Hz which it doesn't, it just gives it a decent operating range as a whole system (a 5.0 system not 5.1). A 5.0 system is a 5 channel system, a 5.1 system is a 6 channel system - just another fact to throw out.

Wikipedia.org[/url]"]5.1 Channel Surround (analog matrixed: Dolby Pro Logic II)

Extracts 5 audio channels and 1 low-frequency channel from either a specially encoded two-channel or a stereo source:

* Two channels for speakers at the front - left (L) and right (R).
* One channel for speaker at the center - center (C).
* Two channels for surround speakers at the rear - surround left (LS) and surround right (RS).
* One low-frequency channel to drive a sub-woofer.
* Describes the Dolby Pro Logic II matrixed surround system. Source media is often branded with "Pro Logic II" logo. Most modern theatrical motion picture films include a digital soundtrack in this format.
* Surround sound speaker placement: (6 speaker channels in total) surround sound speaker placement is different for both music and movie content.

For music, speakers placement is unknown.

For movie surround, the front speakers should be placed at the edges of the screen, toed in to face the central listening location, and the tweeters should be ear height. The center speaker should be placed behind the screen (when using projection) or over or under a TV, and as close to ear high as possible. Rear channel speakers should be placed high on side walls, slightly behind the listening position, and should have a normal high-quality monopolar construction.

I have various "subs" rated for 40, 50, and 60hz but I still love playing that bass test track (starts at 320Hz and goes to 10hz in 10hz increments... neighbors don't seem to like that one much but I think it's pretty awesome :twisted: ).

:thumbsup: for having an preference/opinion, without it the world would be dull.

 

[astrallite]

Undoubtedly so. But even the 10" Logitech is overkill by a factor of about 4. So what is the advantage to an even more preponderous bass?

Those bigger drivers are usually more linear, meaning they can maintain the same volume down to lower bass registers. If all you want is "audible" bass, then a 6" driver is the best subwoofer ever designed, since it can do the upper bass range of 80-100hz better than a 10", all things equal.

 

[flasher702]

making your g/f orgasm with your stereo is not preponderous...

"overkill" is pretty subjective and it also depends a lot on the listening environment. For a car a 10" sub is slightly excessive. For a stadium it's laughably inadequate. Most people's living rooms are somewhere inbetween 😉 More is almost always better and the example above is not the only quantifiable benefit of having a nice sound system. Of course you eventually run into constraints such as budget and space. I went to pack up my sound system the other day to take to a friends house and realized it wouldn't fit in my car unless I buckled the dual 10" enclosure into the front seat. At that point it struck me that it was a bit preponderous, as you say, to have so many large speakers for what is essentially a home stereo system so I sold that cab and I'm trying to find some new smaller speakers. I really had my heart set on some portable 3-way ~200w full-range speakers with maybe a single 8-12" woofer but they don't seem to exist :/ I absolutely adore my 3-way 260w Technics towers with dual 12"... but I'm tired of lugging them all over the freaking place every time I move or get drafted to run sound. I really can't bring myself to buy "computer speakers" though. Even if they do have good sound quality for that kind of money I want to be able to do a bit more than get surround sound for movies in a small-medium sized room so I really don't think they are "overkill" at all.
