You mean 170db? good luck. 170hz no problem.

 

[Bring97 10+ year member]

yeah i meant at 170Hz. so that should be ok?

 

[maniackilla 10+ year member]

what is your question? your not gonna hit 170dbs and if you play 170hz notes you are also crazy

Oh i know i wont hit 170dB, my question is how do i move the hz down and keep the dBs up with Winisd Pro?

What is a winisd pro? use a crossover for the frequencies. as far as db's go, To gain dbs you must either increase power or speakers. If you had a 500watt amp and upgraded to a 1000watt amp you would gain 3dbs. Same thing with speakers if you have 1 12 and add another 12 you gain 3db.

What is a winisd pro?3db.

WinISD is a software used to help with enclosure size for sealed and ported enclosures for any sub.

It also tells you when you will hit max SPL when tuned to a certain frequency.

i know what and how to gain dBs. Ill restate the qustion,sry for the bad posts above. Im looking at a graph in a program WINISD Pro and a graph that measures spl reads that to hit 147 dB i will need to play a 150Hz note. so how do i lower the Hz and keep the dB up while doing so?

Theoretically.

Anything over 100 Hz for a subwoofer setup is way too high. Most SPL meters won't even pick up SPL at frequencies over 100 Hz. The way to get a lower peak is to tune your box WAY lower, by making the port(s) longer. Are you going primarily for SPL or do you want any SQ as well? I would tune around 45-55 for pure SPL and 37-44 for a mix of SQ and SPL.
