10's or 8's...worried about low end.

[RedStangHappy 10+ year member]

Because the specs SAY they can't. Not me but the company.

they'll play any frequency you send it. Playing it audibly and safely is another thing though...

Oh my god you sir are a Fucking moron. I cant believe the amount of stupidity that has been blown out of peoples ***** in this thread.

You're right, they cant. I dont even know why companies make 8" subwoofers then. Thanks for clearing that up. //content.invisioncic.com/y282845/emoticons/rolleyes.gif.c1fef805e9d1464d377451cd5bc18bfb.gif//content.invisioncic.com/y282845/emoticons/*******.gif.a649d21efc0d1fd4890a6428166586c1.gif

As I said in the beginning you sir have NO answers so you revert to flaming to cover your own ineptness. I didn't call your name, when I asked the question. SHOW me an instance where, without distortion, an 8" sub hits 15-20 Hz. Without the random and idiotic name calling

HT subwoofers do that all of the time.

Cool....what is HT? As I said newbie to car audio //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Distoriton has nothing to do with the sub being able to play the note...it'll still play it, regardless of how distorted or clean the sound is.

The question is, "how loud can it get before driver distortion sets in?" Once you get past xmax, nonlinear distortion beings to set in pretty quickly (in most cases). When dealing with subs from the same line, say an RE8 vs an RE12, while playing a 20hz tone both subs will start to excurt nonlinearly after the same amount of xmax.

Of course it will seem like the 12 is "diggin deeper" because it can be heard over the 8, even though the 8 is playing the exact same note, just as well (just not as loud). Now, if you take the cone area advantage away from the 12" subwoofer, and use three 8's instead (roughly the same cone area as a 12), then you'll see that the 8's will produce the 20hz tone just as loudly as the 12...

And the answer you give is pretty much what I expect.....but as I have said I only want an example of it being successfully done. I know that with the combined cone area, it should work. But as I have said, I know home audio, you don't get more drivers. I just want an example.

Home theater...8's tune to high teens-low 20's can get pretty low.

OK I have never seen an 8 inch sub play cleanly at 20Hz ever. I have heard of lots of things in Home audio, ie, Bose makes some of the best sounding speaker. None of it has ever been true. I base my thoughts on reality. Things I can prove, not with my words, but with proof. If you have proof, just show me....I'll have my answer, Thanks //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

As long as it's playing the 20hz tone within it's linear xmax, it'll be clean...I don't need to show you, it's just common sense.

Would you like to tell me exactly what specs dictate exactly how what ranges a speaker will play? If you say frequency response, your wrong....

There's nothing magic about adding 2 extra inches of cone area nor is there anything magic about 20hz. All 20hz means is the speaker moves back and forth 20x per second, it doesn't take a bigger speaker to move that slow, seriously think about it. The only difference is it takes more displacement to reach a given output at those frequencies. Each time you drop an octave a driver has to displace 4x the air to reach that same decibel level. Given that, a larger driver will move more air per amount of stroke, keeping that given SPl level for longer. However, the actual frequency that the sub can play is limited mostly by the box it is put in.

 

[RAM_Designs 5,000+ posts]

Explain how it isn't capable of playing 20 Hz or lower ? Where's that proof ?
A speaker is nothing more than an electromechanical device (like an oscillator) that responds directly to the input voltage. Distortion occurs when the speaker exceeds the mechanical or electrical limits of its design. NEITHER FORM OF DISTORTION RELATES TO SPEAKER SIZE.

If you send a speaker a 20 Hz tone and it remains within the limits of its design, it will play it without audible distortion, regardless of its cone area.

If you don't understand that, I can't help you.

Exactly what I was trying to say, but much more intelligent sounding //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

I have heard of lots of things in Home audio, ie, Bose makes some of the best sounding speaker.

That's pretty funny seeing how Bose sub's don't actually play bass. I'm pretty sure that they use some sort of processor that sends a signal that is actually a combination of other frequencies that gives a similar sound as the actual frequency that went into the processor. I think the bose subs are some of the most fake sounding subs I have ever heard and that was before I read about their processor. I wish I knew more about it as I may be off but I'm pretty sure I read about it a few years ago.

These two subs could get **** low:

The HF could easily play flat from 20-70hz in the correct enclosure. There would still be significant output below that as well.

Here's why http://www.answers.com/topic/subwoofer?cat=technology. And to further prove my statements http://www.velodyne.com/products/specs/cht_r.html Velodyne is one of the best subwoofer suppliers in the world. The specs continue to prove beyond a resonable doubt, that 8" subs DO NOT go as low as larger subs. I thank Immacomputer, because unlike the rest of you with nothing more than your words and your flames, he is showing me speakers, facts not like I said I knew it all, or I was right and you were wrong. I said I have not heard an 8" sub go that low. And I asked for someone to name one. Out flew the most popular brands and the specs stating 32Hz as the lowest. The Dayton RSS210HF-4 8" Reference HF Subwoofer 4 Ohm at least gets to 27 Hz. So stop with the name calling, childish net thugs do not move me, and show me proof. Not theory, although with enough drivers even 2" speakers can give a full range, just not as accurate as larger speakers can. I know that, I want reality to set in. You say it's common sense, then why is there no picture of an 8" sub at 20 Hz. You have said over and over it is easily done, now show me. Or like the frauds you are beginning to sound like shut up and let a real person with knowledge answer me. I have said repeatedly, I don't think it cannot be done. I just haven't seen it. Thank you.
