Also, Fs is just the point at which Re is highest in a free-air environment. Also known as free-air resonance.

Also, a ported enclosure will generally maintain SQ to about half an octave below tuning.

Also, a subwoofer will generally be fine (I.E. not bottom out) to about half an octave below tuning in a ported enclosure.

I've graphed, built, played, tested, and graphed again, many ported boxes.

I know what Fs is.

I never said anything about losing SQ.

I never said anything about bottoming out either.

Re: Speakers came today

15Hz in a vehicle is just killing output, name one song (real song, not techno bass mix) that drops below 20Hz. ill Mail you $1 if you can find one. the only real song i know of that drops near 20Hz is "Dirt Off Your Sholders" and that is in 2 short (15-20sec of the track in total) modulations in the song and its recorded at -4dB if i rememeber right.

Only other even techno bass mix that isnt just like a 10 or 15Hz tone is "Bass I Love You"

Mid 20's is as low as you need to go in car and even that can be over kill.

Re: Speakers came today

So what frequency do you commend I tune my box to CB. I do listen to all different type of music and do know that the L5's were mainly for spl and not sq. But what do you think is a decent tuning?

Yes, but if your box is tuned to, say, 20hz and your vehicles resonant frequency is 43, your peak will be between the two, so your 20hz tune won't sound all that great. You want to tune it lower, so that when that tune mixes with that of the vehicle, the output peak is closer to where you want it. You usually want the peak to be low low, as those tones are harder to hear and the output levels out about 10hz up from the peak(if built correctly).

1. Graphing on a computer means nothing in a vehicle.

2. Building means nothing if not built properly, or designed properly.

3. Apparently you didn't know what Fs was, or you neglected the definition. Or, more than likely you didn't know it's REAL significance. You tried to incorrectly use the term as a basis for your incorrect assertion.

4. Never said anything about losing SQ? Must I remind you of what you said?

Thanks.

Re: Speakers came today

dang, you mean I can alter the vehicles resonance by tuning a box to like 5 Hz ?

Re: Speakers came today

Sonoma, reread my 1st post.
Id say prolly mid 30s will be solid to get a nice mix of sql... lower for more sq higher for more spl.. its pretty simple and it is mostly up to you. if you hate the way it sounds you could always rebuild but low-mid 30s is generally a pretty safe tuning.



FRYMAN.. hoods run down- lil wyte ft. frayser boy. 15 hz.. you can send me a dollar now.

Re: Speakers came today

Wow, I cannot believe how ignorant you "Audio Gods" are. I didn't say you could alter your vehicles resonant frequency, I said you can put the emphasis on tones BELOW the vehicles resonant frequency.

ngsm, I'm sorry I forgot what I said, since I don't the internet as seriously as most of you. Everything is shitty below tuning, that's why it's called TUNING. Does your car run optimal when it's below tuning? No? Point. When does graphing on a computer via mic in a vehicle mean nothing? Apparently it works great for SPL and SQ competitions.

Further educate me? I'm a lot smarter than you think you are.
