So i have two of theese speakers Szerokopasmowe
cheap ones yes,gonna use them with some dinamic tweeters and 2 way crossover and i want to squezee the max of those speakers ,btw didnt found a section in forums for box building tips so i hope some of you can help anyway
few questions:
would theese speakers be able to hit lower notes below resonant frequency 51hz ,would it hit something like 45hz ?? if so then i would tune box to 45hz because i want to get as much low frequency of them as possable maintaining as high as possable db level and keeping total distortion level normal.
also what kind of box you suggest to get the max out of them ??? sealed ? ported ?? and what kind of box size in liters ? i decided to make about 93 liters sealed enclousure but then it would not go at all lower then 51hz i guess ,help me with all this confusion ,just begining to learn basics

With a Qts=0.91 the motor is just too weak for bass, it's not very efficient either.
What other brands do you have access to?

so you suggest to tune box to 50hz ? sealed or vented ? i don't have any access to any of other brands as i said i allready bought theese and now i have to deal with what i have....
btw i put one of them for testing in spare car subwoofer box and it's hiting 40-45hz notes quite nice but not very hard... well i do have other spare subwoofer for low notes but anyway wanted thoose speakers to hit lower like 45hz cuz mostly all important most common bass is from 40-50hz roughtly saying.Still waiting for suggestions about box build.But don't suggest any other box types besides simple sealed enclousure or ported.

I'm sorry I'm not telling you what you want to hear.
Sealed box will make it roll below 100hz, then add a sub if you need more bass.

i am not asking if it would go below 100hz in sealed,that's obvious.... just asking at what hz i should tune box for maximum bass ,or it doesn't matter any sealed more then 50 liters would do 50hz fine ??? or it's worth do vented for 50hz ??
glad u made that clear now... so maybe you could calculate for me what would be optimal sealed size of the box in Liters for theese tuned to 50hz ? is it even worth it to make big box like 80-93 Liters or smaller 45-55 Liters would do 50hz fine with very similar dB like biger box??
You can't tune a sealed box.
Your best bet is to download WinISD or Hornresp and play around with enclosures. Porting might be possible, but the response will be all over the show. Have a play and see what you can live with.

thnx for suggestions ... but what you would do ?? i do want theese speakers to go lower then 50hz ,allready tested them in small about 45 Liter aprox 40-50hz tuned subwoofer box and they do hit lower then 50 hz actually from 40hz ,from 40 to 45 almost no diffrence yes db level at that low bass would not be high but maybe worth a try with ported ? or just make a random sealed box ? ,gonna try theese programs what really VAS means ?? the reccomended volume of sealed enclousure ??
because it's more simple and easy allready have 1 box that size only need to seal up the port hole but diffrent wood ,more thick about 1.2cm but also more dense,other box will be with 1.6cm thickness but less dense.Also wondering to put filters for them or not or just add dinamic tweeters -3db capatitors along ... if i would add filters then probably would cut off full range ones at about 4-5khz then tweeters would go from that to 20khz not sure if it worth the price to do so
