  1. 5. Responses in 25min?.. You a internet killer fosho. U win... U da man... Bass On!
  2. The truth.. not lame just tired of your learning curve sir
  3. Bass on... bro? ...I share, not a vid ho or stick a sticker on my car. But I WILL demo... smh. Misinformation... you giving advice on port area vs sidewall clearance... "end correction" facors into that surely... how?
  4. ok then pal... talk to me on another board then... but U post like there's no tomorrow... its cringy The free world dont hinge on your limited knowledge. Bass-on
  5. We never spoke my friend... let's be clear. 1400 posts without a build?.. really?.. I cant find your builds anywhere
  6. Only misinformation mr sherriff... singing off once again
  7. Basic?... say my name I'm a noob too 1.21 gigawatts
  8. Omg... if you're trying to size a port with higher power... modeling can give you useful info, A calc is a shot in the dark imo... extreme power with a set excursion usually A calc is only useful with lower power situations... add 30mm of xmax and 2K clamped /w/ filters and that calc gets beat pretty fast. This thread should encourage noobs to learn modeling.. NOT rely on a calc.. power is cheap and most are looking for hi-power solutions.
  9. Lolol... it's a mix of knowledge.. but drawn up in sketchup. After modeling, roughing in the space in Torres, rechecking dimensions and volumes once drawn up... "end corrected" if neccesary then final volume/tuning is determined in Winisd once everything is factored in. Really?... there's no program for this. This is what a designer does my friend... a specfiic enclosue for a specific application. I've done a few, yesterdays.. or this mornings design... it all seems the same to me anymore. Here's one from 6 months ago... I just try to help people... as best I can
  10. Yup.. model it up. The results are worth it. I model dozens a week... some bang even tho they're lower grade. And ya... system setup counts. Nobody understands a ssf or types/slopes. I'm a noob myself pal... Now sizing that port involved the end user... and his planned "power"... lol... Ds18 all the way! Designing enclosures can be challenging... Thankfully I'm an "enthusiast"... and don't normally charge.
  11. End correction?... your really using terms you don't understand... that's only 1/2 the port width basicsally before you neasure down the center At the entry to a 3 common wall port internally once again... And that's the flaw? Learn modeling
  12. I always setup winisd with Q factors/specific losses and temps before modeling... once the enclosure type to be used is determined. I look at loading and impedances within a desired volume tune and compromise as all enclosures have to be... no unicorns in the enclosure world but best is what you end up with. And ya.... subsonics can and will drastically affect port velocities in my exp. And that affects port sizing... what you think will need 68in2 of port can drop to 55in2 and that affects length drastically.
  13. Meh.... modeling lets you determine a ton. Instead of dinging the calc... realize its limitations and either model or find a knowledable designer. There's a reason I lurk around here... lately a ton of disinformation seems to be normal. I size MY ports properly and have designed a couple... lol
  14. What kills me with all these calculators is the way "rules and givens" are used. For example... a box tuned 32hz at the drivers limit will likely need a subsonic. That Subsonic will lower port velocities drastically... making a smaller port feasable. Volume/tuning power and filters affect velocities and to properly size the port area modeling can't be beat imo. Now I've "undersized" my port for a given volume/power and seen 140fps+ but after setting up my filters correctly when modeling it lowers it a good bit under100fps. What's hard to figure accurately is actual power without testing... Imo once your power is figured port sizing is a snap
  15. EVERY knob to the left except gain?... I'd raise your lp to past sub frequencies (remove it basically) and control your LP thru that Hu you got... The Ssf (Hp) on the amp I'd set to around 20-25hz to protect the subs under tuning... All knobs to the left except gain? Btw... If that was my car I'd spin that box around, reinforce the rear deck (deadener or wood/foam), modify the opening till the subs cleared into the cabin and tie it all together solid while sealing it off. Face em front and trunkwall it... if you got a 80prs and yinlong bank already.... go for it and trunkwall it. It DOES look kinda tight and the rear deck looks bare and flimsy. Then add power... haha
