HEY JDM NEED YOUR ADVICE iv recently been advised by someone on audiosciencereview told me about my planed design a two - 5.215 cubic ft cabs that i shoud check the air velocity m/s reading at peak via rear port' from WinISD they said id ideally want

[@JilesMcCoy]

Design isn't my strong suit.... but 55m/s seems to be quite a bit of air. Some designers I talk to look more at a 25 or 30 m/s as a maximum design criteria. Of your 2 options above I like the 2nd. If you can achieve 115db at 20hz I think you have won the game. Have you considered using passive radiators?

[@TheHandyHam73]

Always seal wood with a sealer before painting. You want the paint to stay on the surface and not soak in thus creating a paint film which uses the perfect amount of paint with minimum waste. A paint film will give you maximum finish results with minimum effort. A sealer does not need to look good either just spray or roller it on without regard for looks. Paint is always way more expensive than sealer so this can actually save you money while improving your results. Great video!.

Thanks for the tips!

Awesome video. I am getting ready to put together 3 of these cubes. I have two questions. Did you wire the sub as shown on the instructions pamphlet shown in video? 2nd is what terminals on the Neutrik speaker terminal did you connect to? Mine have 4 connection points. Thanks again.

[@JilesMcCoy]

Hey! I wired the voice coils on my sub in series so they would present a 4 ohm load. I only use the +1 and -1 terminals on the speakon connectors. But I always buy 4 post connectors just in case I ever want to use that down the line... but I’ve never come across a use case in my home theater for 4 post connectors yet.

[@JesusChrist-em8gj]

Thank you so much. Exactly what I needed to know.

[@philschniter6429]

Great build! Any reason that you chose that particular driver? I realize that the drivers with relatively high Fs like that one supposedly sound better for music (vs home theatre), but the NSW4018-8 is not cheap!

It was just to try something different. The UM18-22 is a very good choice for this box too.

Curious how the performance would compare to something like the SVS PB16 Ultra. Even with some great drivers and amplification, these are so much cheaper. Thoughts?

[@JilesMcCoy]

I do t have a PB16 to compare to but my gut is that the DIY is going to give you more output. I’d love to get me hands on a PB16 to test with. The products are targeted at completely different consumer segments though.

Nice vid! Keep up the good work. Btw how is the eminence sub compared to the Dayton sub?

I am still formulating my opinion. It seems like it needs more juice to really open up.... but I need more time with the sub. I just got it plugged in!

[@fooschnickens]

@@JilesMcCoy Being a single 8ohm coil isn't doing you any favors, the Eminence was designed to work in pairs in a single cabinet to give amps a much easier 4ohm load to drive. The ultimax can be wired in a 4ohm load out of the box which gives it a definite advantage in selecting amps to match its power handling. There aren't many amps that can meet the Eminence's 1600W RMS rating that don't cost several times more than the cost of the sub itself! An NX6000 is probably your best bet, or a secondhand XTI6002 or QSC PLD/PL380 but those will easily set you back $1000+ even on the used market...
