Tuning on the split folded port is much lower and I love it. Wish I could send you a pic but I had to thank you for the videos. Glad you made this

The port was in a fold formation in the video. But he changed that. I kept it the way he had it in the video. The port folds over itself. I haven't measured but it hits lower because I built 3. One with the 24" port. The other 2 with the 40" port. I haven't bought my umik yet so I can't measure.

im going to build your design. Thank you so much for the detailed instructions! I have already built a pair of North Creek Music Borealis main speakers but need a bit more lower end for listening. One question I have is that the bracing in my NCM Borealis' has round holes that have the edges rounded over to prevent chuffing. Can the window pane brace also use this method? It might be a bit easier for me to cut out with a hole saw.

@hometheatergurus 27 күн бұрын

Sounds like you've got some diy skills. There's no need to round off braces as there's not nearly enough air velocity passing over a brace at any time to cause any noise at all. Just hit it with some sand paper and install. Now ports you can round over if the port velocity is close to a near audible speed and it can help. These sub ports are not audible so no need but you can. See the community tab from the channels page as there's an updated cut list.

Hey man amazing channel for someone like me... I loved going to the movies 1x a week then COVID... but because of your content I have found a new hobby. Few months ago all I knew was Bose... now I got 2 DIY subs glued up, drying in garage with 3 HT2 flatplacks on deck. Everyday I look forward to getting in my theater or in my garage to do some more work, I didn't have that fulfillment before so thank you. But I have a seal issue, need advice. I tried 50/50 glue water but the annoying little gaps just soak it up. Can I use my PL premium to cover the outside joints and flattening the bead with my finger for good seal inside and out? Or should I use water putty that I saw you had in Exohyde video? I want to do it the best/right way and I appreciate any help.

@hometheatergurus 3 жыл бұрын

That's Awesome man! Love hearing stuff like this. The glue mix is just to soak in and seal the edges. It doesn't fill gaps. Use a filler like bondo, spackle, water putty or similar. Fill, let dry and sand smooth.

I leave MDF projects under the heat lamp for a week, or so, to fix that problem before painting. Does PL Premium shrink, also? Perhaps it's the adhesive I should be using to improve my process.

In one of your earlier videos you mentioned you started out building with sonotubes. Is there a reason why you are building a box version as opposed to a cylinder version now?

@hometheatergurus 3 жыл бұрын

20 years ago there were no kits. Most every DIY sub guy designed his own sub. Sonotube subs were everywhere. SVS was selling them lot hot cakes too. They were very easy to build and you could make them look really cool. These days they're just less popular. Rectangular subs are easier to fit in tight spaces and have a higher WAF. I also like rectangular because I like a more challenging build. That said the Sono Subs performed every bit as well if you designed it right.

@mahster 3 жыл бұрын

@@hometheatergurus Haha. I guess WAF is a big factor. Do the Sonotubes lack the rigidity of the box enclosures? I've seen some tall tubes and wondering how they could possibly be as rigid. I've played with science demonstrations where the tube tuned to the correct harmonic amplifies the wavelength so much. But I guess those demos were of ported designs. I would think a well tuned tube sub of the same volume, offer better acoustic amplification. Just trying to research and understand the differences between the two.

I much prefer a plung router. Especially when making multiple passes and going a little deeper with each. It's faster. Just make sure the clamping or holding mechanism doesn't allow it to walk lower. Some especially an old Dewalt I had would do that.

You mentioned the simplified vent in the video which is good, since I was wondering how the rear mounted amp would fit as it was originally configured using the subbox.pro website. You said that the new vent length bumps up the tuning frequency a bit. Do you recall what that frequency is, for those of us trying to follow along in WinISD?

Winisd is a tad off with slot ports as it doesn't account for the side wall of the cabinet extending the port so it was originally a tad lower than 20hz verify in REW.

@hometheatergurus 4 жыл бұрын

We know where the sub is tuned and we can see the filter and where the cut begins in the Minidsp plug in and the amount of cut it applies at a given frequency. We're setting it to begins little above tuning but it's also an aggressive filter. You can definitively do a less aggressive filter but I'd be careful. The cut sheet is in the video but the back opening is actually a small continuation of the port.

It would be very time consuming and a major headache. The Mindsp makes it too easy as you have full control of 4 sub in one interface.

@@chandan6119 it's not a simple answer really.. If you have a sealed room and you want low and I assume by low you mean under 15hz sealed will get you there but you may need 4 or more depending on your levels. I know guys with basically hammers (subs I designed for them based on the um12) and 2 are pretty brutal but of course they aren't listening at reference. I'd say it's similar to pb13 performance. If you are in an open concept room and want output down to 20hz id choose the hammer or if you want more output a full Marty of devestator type sub for extreme output. A ported sub modeled like the hammer doesn't need room gain and is flat to 20hz before it even begins falling at all. I'll be using 4 hammers stacked in a tower system with tow hammers per tower once my new house is built. They'll be in a very large open area that's roughly 30x40. But now in my theater I was thinking sealed for low end extension but now I'm leaning toward a pair of horn subs. BTW the Hammer may be available in a CNC'd flat pack very soon.

Speed. Screws require predrilling and it's harder to hide screw holes. Glue and brads are super fast. You can actually glue and clamp as the glue is strong enough alone but it takes too long for me to wait for glue to set as you have to wait for panels to dry to move on to the next set of panels. So I use glue and brads to get through it quick. A lot of furniture and cabinet makers use this method as well. Once you try it you'll be sold. Used to use screws but it's been along time ago.
