Thanks for your efforts and the free plans. Two of these subs would kick some serious butt!
I really enjoy watching you build these enclosures. Your analysis is spot on and very sincere. All of your topics are of interest to me and you cover a lot of ground when doing your presentation. Keep up the great work and thank you!
I love these videos
You should resize your vertical scale windowing in REW, try a standard 50dB scale.

Hi M!
It would be intresting to see you building a 2.1 bluetooth speaker with, for examle Arylic 2.1 amp. What to think of sensitivity/impedance in this case between the drivers?
Nice courses and vids 😁
Do you have any thoughts onto turning a smallish centre speaker tuned to 65hz, into a small, portable passive radiator sub tuned to 32-38 for a DIY portable BT 2.1 speaker system?
Thanks for the video, very informative. why didn't you use RSS210HF-4? HF seems better. I'm planning to the same thing only with RSS210HF-4 and RSS265PR 10" in the 20 liters box. Do you think going with 8 inch + PR is better or just one sealed RSS315HO-44 in the 20 liters box.
Hi, is there any way to measure Vas and Qms of a random(DIY) passive radiators
Why would anyone prefer the higher tuning? I would even make the box bigger and tune it below 30Hz to get more low extension for home theater use
This is the question I also posed. "Most people" wouldn't want a "subwoofer" to only play in the ~40hz range at all - at least most "knowledgeable" people.....
Wow nice build! Have you ever tested a pa subwoofer for home audio? Thypicaly the kind with ribbled surrounds
I actually haven't played with pa drivers yet.
Hi maxim, I did try that, I have a 18" dj subwoofer in my living room, connected with RCA's, for music and especially watching movies, it is AMAZING!
Hi. I noticed that in most of your videos the microphone is not picking up all of your voice. It becomes difficult to hear you speak unless the volume is loud or one is using a headphone. Please use a directional microphone, if possible. Thanks!
Hi i want to learn design enclosures for 18" and 21" speaker around 1500 to 2000 watts where i get the details for course or any learning videos or softwares
Nice video, thanks for that and also your box calculator. It appears that the drivers are not flush mounted. Does it matter on subwoofers? Or any other driver? Thanks
There may be some difference when it comes to bookshelf, floorstanding speakers. However, for subwoofers I doubt there is any.
Hello. Please also tell me why a passive loudspeaker membrane is called a radiator. Radiator of sound? Thank you.
love this video but all that work with the MDF and u could have just made it out of solid walnut or oak
Most of the build was nice, but I would have put the connectors on the bottom of the box. Having them stick out of the side takes away from all the clean lines and final finish.
Other than that it looks nice. Too bad you couldn’t get some golden brown speakers to Colour match the enclosure.
Volume (in vid) a tad low ? All PRs tuned to same frequency? Are they in-phase or out at resonance?
Volume is fine in my opinion, turn it up if you find it low. All PR's are tuned to the same frequency, yes. And last question, I assume you are asking how I wired the speakers. Both speakers are wired in-phase.
those dayton passive radiators cost more than the subwoofer itself
What kind of plywood/wood are you using for your builds?
I use MDF
Where is the Info of the xover?
There is no xover. This is a subwoofer
Salut ! Vreau sa fac o boxa portabila cu un subwoofer dd audio 606 6.5inch și amplificator de 350w pe sub, am o problema , subwooferul are xmax 9mm , care după rodaj cred ca are 10mm și nu găsesc radiatoare pasive de 6.5inch decât cu 8mm xmax , sunt ok 2 radiatoare cu 8mm xmax sau sa cumpăr doua de 8 inch cu 11mm xmax ?
Se ia in considerare si aria difuzorului, nu doar Xmax. Daca inmultesti aria difuzorului (Sd) cu Xmax iti da un parametru care se numeste Vd (uneori il gasesti in lista de parametrii). Vd-ul radiatorului pasiv trebuie sa fie de cel putin de 2 ori mai mare ca Vd-ul difuzorului activ. Daca e de 3 ori mai mare eu zic ca esti safe. Sincer eu m-as uita la radiator pasiv de 10" sau 2 de 8"
Salut , am construit boxa am luat 2 radiatoare pasive dayton audio epique de 7 inch , problema e ca fs a ajuns la 31hz (hz 0:01
Cred ca te referi la Fb (resonant frequency of the box). Si de ce e problema? Vrei mai jos? Mai adaga greutati pe radiatooarele pasive. Ele vin cu niste discuri care se prind pe spate. Sau daca vrei Fb mai sus, mai scoate din discuri
Scuze , nu terminasem mesajul ca m am luat cu altceva și nu știu de ce sa trimis :)) . Am văzut pe yt ca poți sa vezi ce FS ai daca rulezi o aplicatie cu diferite frecvente și la o anumita frecventa difuzorul nu se misca deloc acolo e FS subwooferul ui , la 31hz nu se misca difuzorul iar pasivele se misca foarte bine , nu este ideala o frecventa de 37-38 hz ? Pasivele nu au nici o greutate adăugată, am scos și șurubelul în speranța de a creste în fs :))
Nu exista o frecventa ideala. Mie mi se pare mai bine 31, dar fiecare cu preferintele lui. Nu mai ai cum sa ridici Fb daca ai scos toate discurile. Doar daca mai adaugi un PR (sa fie 3 la numar)
What amp did you use with this sub?
Dayton audio spa250. But you need something with roughly 500w at 4 ohm
@@AudioJudgement thank you! And how are the subs wired? Could you please provide a diagram?
They are wired in parallel.
@@AudioJudgement thank you sir! And thanks for the great videos
I don't know why you'd claim that: "Most people don't want to tune it that low" - in reference to tuning the PR to 31hz. I'd wager that "most people" would want it tuned even lower - to 25 or even 20hz (the Dayton RS subs will easily play that low). A "subwoofer" that only plays in the ~40hz range isn't really a subwoofer at all - but instead is more like a Bose "bass module", in that it only plays in the 40hz range. 40hz is more midbass than subbass.....
I totally agree with you and I much prefer a sub tuned lower. But in my experience people like to tune it higher, because they get more output from a smaller box. And I heard people say that "the port is not tuned correctly since it's barely moving any air" (port tuned at 21 Hz). That sub was playing linearly down to 20 Hz, but since many tracks don't have 20-30 Hz notes, it seems that the port is not doing anything. I might be wrong, but this is my experience, that people tune the box higher, not necessarily for the right reasons.
