Hey, in my opinion I think a Dayton Audio Classic 18" 4 ohm woofer would work better for what you did here. It has a FS of exactly 25Hz, and it hits low frequencies like crazy. only 125$ too 300watts RMS
blankpaper66: @AudX Thanks for the large response man! :D
AudX: ber are only options
2) take the volimeter, play sweeps look at the highest voltage points at speaker terminals. these are resonance freqiencies. compare this with your software model (winisd probably). You will notice it differs from theory. Change port diameters untill you get resonance at projected frequency. Fix the port diameter permanently. you are done. This can be done in your room.
First option is much better though...
AudX: @blankpaper66 You've got 2 options
a) use your ears. put the enclosure outside (silent garden), stand couple of meters away (where the bass is strongest), play sine waves sweep, use db meter to see if the response is flat. If it is not - alter port diameter by putting eg. wooden stick inside untill it flattens out. Once you reach flat, punchy sound you are there. Change the port diameter by equivalent of added square cm of wood sticks. You cannot do it in your room! open space or anechoic chamb
blankpaper66: Dumb question, but how do you actually "Tune" a port to work best at a certain Hz? Always wondered haha
blankpaper66: @vietstyle888 Yep, i know it's a old comment buy there's no reason not too, but as the uploader mentioned, most of them aren't meant for home use. Many manufacturers actually make ones for cars and for home use, but SQ (Sound Quality) brands like JL Audio or even ascendant audio have several SQ subs which can be used inside. JL are #1 for SQ, yet they still slam, they also have a home range, while others like AA can be used inside, but aren't really meant for it.
s1mm3g: and just hope that your neiburs like your music
P90xFitnessExpert: Keep it Lound and Strong...
AudX: @skylinelad09 no way dude! it's actually quite big. 2 ports each 4x50cm. That comes to 400 cm2 and that equals one square port of 20x20 cm. Thats biiiig. And finally there are virually no port noise. So it's good!
AudX: @mrPEPELDO Bil Bless - Squarnch. Tak - szfka jak szafka - pierwszy projekt, więc bez zbędnej fantazji. teraz rzeźbie ciekawsze rzeczy. skończe to pokaże.
skylinelad09: port area for that size box is way to small !!!!!!!
Tom Dodsferd: Video test ?
AudX: @vietstyle888 some ppl say car subs are too rough, harsh sounding for home use. they are mainly built to reach high SPL with powerful amps in mind, and home speakers quite opposite - less power capacity, ligher cones, more delicate suspensions, better sound precision. Car audio components are made to look good not exactly sound good but there are exceptions. All in all if you start the home project with no components - why not to go for these for home use. I'm happy with my Black Air
Tossdarice: I have one question though. but it might be stupid.
Can you use a car sub as a home theater sub?
mrPEPELDO: wie ktoś jak się ta muza nazywa ? a co do pudła to nic specjalnego , stara szafka z głośnikiem :-) 0 weny twórczej !
AudX: so cool to hear from a soulmate ;) squarnch is a masterpiece indeed
bsod4u2: WinISD is a good starting point, however your box needs bracing. These walls flex, even if minor flex you lose SPL this way. In have a clip of my wall of subs on YouTube, all home made cabinets(sealed), braced to the grills.
Sto razy lepsze od wiely "domowej" roboty subwooferow YouTubie.
Radu Emil Nutiu: tnx for sharing
changoskillz: who drives around jammin this?
TRUCAJES: menudo burracon un poco mas y empotras el subwofer en un armario jajajajaja aparte que el subwofer es un mojon de que te sirve tanto cajon eso es una tartana
