Weng ma-mount mo ba sa sub enclosure yung NU3000? Fathom na Fathom.

di pwede e mount sir kasi lalampas ang total height ng sub sa bottom of screen. sa rack ko nilagay ang inuke at doon ipa-fathong ang midiDSP sa inuke amp

did a quickie test on the inuke amp hooked to my diy sub, it did gave life to the kappa sub which had not seen action since i got the PB13 2 years ago. now, the midbass came alive on the kappa with some clean output down to 20hz.

watched some snips of WOW and FOTP, my couch shook literally. the PB13 can shake the couch alone but this time it was like sitting on a massage chair especially the scene on FOTP where the plane was rolling. i was tempted to turn up the receiver volume to -12db but afraid because the kappa did not have an HPF. will try reference level later once the miniDSP is online protecting the kappa.

next butingting is the miniDSP, eq'ing the PB13U and the kappa sub. with 2 remaining unused outputs of the miniDSP, there's more room for additional subs >:D

the SCS model are neutral sounding at maganda din sa music. with ample power,maganda din ang bass at hindi boomy dahil sealed siya. audition ka kay mikec and hear them yourself.

12" lang brader, 12W7 sub driver.

iniisip ko pa kung mag sealed, "gaya-gaya puto maya" sa F112 pero kelangan at least 1500 watts RMS of power. di na kasi stable at 3-ohm bridge ang iNuke amp. kung one channel naman, di rin aabot ng 1k watts RMS ang 3-ohm load per channel.

so, i'm leaning towards a ported cabinet tuned to 20hz kasi sabi ni kuya manville of JL na kahit 500 - 1000 watts RMS sapat na basta ported. at may spare 2nd channel pa ako sa iNuke amp na pwede kabitan ng another W7 in the future >:D

Okay... to get good output out of a vented W7 as a home subwoofer you will need between 500-1000 watts. We use 1.5 kW on our f112 home subwoofer (which uses a modified 12W7), but it is a very small sealed enclosure and needs the power to overcome its inefficiency. Even 500W will get very nice, clean output as a home theater or music subwoofer.

As a theater sub, I'm slightly concerned about your proposed 20 Hz tuning frequency. For 99% of material this will be just fine, but there are a handful of very demanding soundtracks that are plumbing the depths of bass well into the 10 Hz region. This can cause distress to a vented sub tuned to 20 Hz if you don't apply some protection to it in the form of an infrasonic filter (basically a steep, 24dB/oct. high pass filter just below tuning). You could also play around with your box alignment and try to cheat the tuning a little lower. If you can get it down to 15 Hz, you will probably be safe. It might cost some box volume to keep it flat, but if that's acceptable you will have a pretty spectacular subwoofer with absolutely subterranean response.

Unlike a car, we don't get a lot of help from the room (although we do get some at very low frequencies) in a home setup. In a small room, you can expect some lift below 30 Hz and you should take that into account in your sub's response if you can. In a larger space (like an open plan house) the response will be much flatter so the sub needs to do all the work down low.

Placement of a subwoofer is also hypercritical in a home setup. The space is large enough for modal behavior to occur in the sub-bass range and the placement of the sub and the listening seat(s) is critical. Using multiple subs, distributed around the room, is really the only way to get smooth bass over a large seating area, but good results can be achieved for one or two seats with a single sub if you experiment with placement and use some judicious (CUT ONLY) equalization.

You're never going to get the visceral sub-bass you get in car audio, but a well-executed home subwoofer system can take any home speaker system to an entirely new level of performance and is a very worthwhile project.

Have fun.

yan iniisip ko brader kahit di sila same brand pero almost near ang FR nila. and while waiting to get another W7, i can build a sealed cab for the infinity kappa to work as a midbass sub. i have a miniDSP to tweak the subs to flatten their room response.

Great!!!
Kaabang abang itong project mo brader.
Kapag meron ka talagang proper EQing materials you could combine different brand and subwoofer models...

Dual JL 12W7!!! :o
Order kana brader >;D

did another DIY project on my HT the other day. bought a cinewhite screen material from the US. the material was shipped folded to reduce shipping cost. the supplier assured me that the creases will go away when installed properly.

my heart almost stopped after i unpacked the screen material. this is how it looked like out of the box.



after few email exchanges with the supplier and queries from AVS forum, i proceed with the installation. bought a treated new zealand 4x1 lumber at citihardware, cost was around 1k pesos.


bought 2 yards of velvet at 330 pesos


frame assembly


screen material installation. the material was big enough to build a 150" screen. so, cut to resize to 116".


stretching and stapling evenly following the procedure by the numbers





done stapling, the creases were totally invisible after proper tension was applied to the material. the wooden plank in the middle is a temporary brace to prevent the frame from buckling during stretching of the screen material.



added braces on the backside


closer look of the 3.5" border with velvet cover


the new 116" screen against my DIY 120" gray-painted plywood screen




screenshots
back windows OPEN


concealed lights ON


dimmer lights ON


lights OFF



during my brief comparison, the black is not as deep as the painted gray screen but almost similar though when viewing at seating position. the comparison in blacks was visible a few inches away from the screen. did this with a cut-out flexi white screen placed side-by-side on the gray screen. OTOH, the whites had improved a lot which made the pic quality stand out. 3D viewing is now brighter than what it used to be. not bad for a day carpentry work.

these babies were put on hold due to the late delivery of the MDF boards ordered from cebu. they will get their proper houses on my next days off, 28 days from now.



so, standby muna mga peeps coz i'm away from home, earning a living to support my kaprichus :)

thanks doc. yes, they are the same PVC material elite screen uses according to the gurus of AVS forum.

total cost including shipping of screen material by air is around 6.5k pesos. it would come out cheaper if i had it shipped via ocean freight. but it won't reach home while i'm on days off. so time is money, haha!!
