[SMD DD1 not registering head unit distortion]

i have a Alpine 9887 and a scope, the RCA outs dont clip at full volume.  the internal amp clips at volume 21 out of 35 

[Deaf bonce SA302-12" subwoofer realistic RMS handling?]

did you set your gain like this, if so, what was your target voltage?  test tones are at the very bottom...

[Looking for advise for my daily driver ... Old school Fosgate fan / employee in late 80's]

did you do the big 3 upgrade?

 

and heres the gain setting info.  the test tones are at the very bottom

[Designing a box for my Kicker CompVR]

a flat frequency response = better sq. ported boxes peak, thats why theyre louder than sealed boxes. if the peak is BIG, it will get real loud but wont sound very good

id add a 2nd sub and run them sealed if you want to keep the sq you have but want it louder

[Clipping (what It Is)]

clipping will only ruin a speaker if its too much power for the speaker

an amp that puts out 100 watts, at full clipping, is LIKE putting out 2x the power (200 watts) but if its hooked up to a 500 watt sub, it wont hurt the sub

and if you understand that, youll understand how a 75 watt amp CAN cook a 100 watt speaker

i bought this scope... http://www.elexp.com/tst_hhs5.htm

works great and super easy to use

[Please Help, Whats This Tuned To]

cool... thanks.............

[Please Help, Whats This Tuned To]

and im assuming id use cubic inches for Av and inches for Lv

thanks for helpin my dumbazz

[Please Help, Whats This Tuned To]

its really not that bad...especially if u are decent at excel...i have a spreadsheet for slot ports that i uploaded, if u have excel it should work, although people with vista cant seem to download it...if u want it, i can try and dig it up...

actually, what does ^ mean... ex. (10^

thats not 10 to the 8th is it, been out of school too long

thats alright, i should be able to do it by hand

thanks tho

Fb = .159*((Av(1.84*10^8)/(Vb(Lv+.823*Av^.5))^.5

Fb = tuning frequency

Av = vent area

Vb = net volume in cubic inches

Lv = effective length of vent

effective length = physical length + end correction <---1/2 of the ports width

the complicated thing is the port. the proper way to measure port length with an "L" shaped port is measuring down the dead middle, not of the actual wood you are using, and remembering to add half of the ports width to the actual length. then displacement becomes a bitch to figures sometimes when dealing with "L" ports...well not really, its just a bitch tryin to program it into excel so that it will figure itself out...

hmm, looks like fun, but thanks!

[Please Help, Whats This Tuned To]

i get 2.77cubes at 25.7hz using my calc...thats without sub displacement though...and i made the port 2" wide so i could work with the number easier.

if you dont mind, what equations do you use. i REALLY REALLY REALLY want to learn how to do it on my own

thanks

[Please Help, Whats This Tuned To]

trying to figure out what my box is tuned to and how many cubes it is, tried to use the RE box calculator but guess its not very reliable

thanks

[How Much Does A 12" Fi Ssd Weigh]

cool.. thanks...........

[How Much Does A 12" Fi Ssd Weigh]

couple people over at CA.com are sayin around 23-24 lbs for the SSD

iirc, my HC weighs 41

Probably around 15-25lbs but I have a question why does the weight matter?

lookin to use a different sub than my 12" HC, suckers heavy

SSD seems to fit my system goals pretty good, which are, peform a lot like the HC (i know it wont be as loud) and doesnt need 1k of power or more

gonna use the HC for HT

very nice.. what size box

[Does It Matter?]

why dont you use just one amp, wire up the 2 type Rs to get 1 ohm and set your gain right

sell the 2nd amp or whatever
