Re: $400 CDN to spend, what do you recommend?

My ports have elbows as they were too long to fit. For best results the ports should be one diameter away from any cabinet wall.

Smaller sub cabinets that are tuned low require long ports. After a...

Re: $400 CDN to spend, what do you recommend?

Yes, WinISD is only concerned with the volume for the enclosure. Tube or box, you can use three 4" ports or one 8 inch port. I originally mentioned three 4" flared ports for function and looks. I...

Re: $400 CDN to spend, what do you recommend?

I'm not sure what you mean. The Sonosub screenshot is of the MJ-18M.



Some subs can't be mounted horizontally due to cone sag issues.

Re: $400 CDN to spend, what do you recommend?

A tube would be easier as it's just a tube with endcaps, no bracing to worry about. It can be built with one port which would be a 8" diameter sonotube, which is big enough to allow you to upgrade...

Re: $400 CDN to spend, what do you recommend?

Start with box dimensions that have an internal volume of 13 cu.ft. Subtract the bracing, port and sub to see how close you are. You can make adjustments from there. It doesn't need to be exact, as...

Re: $400 CDN to spend, what do you recommend?

Yes. Changing the diameter of the ports also affects the port air speed.

Changing the tuning frequency changes the port length, not the box size.
With the right sub for a specific application,...

Re: $400 CDN to spend, what do you recommend?

Re: $400 CDN to spend, what do you recommend?

My mistake, I though the ports were 17" long which they need to be for your sub. Contact CSS to see if they sell port extensions.

Re: $400 CDN to spend, what do you recommend?

The net volume should be 12 cu. ft. To that you add the dispacement of the ports, sub and bracing to get the total internal volume. 12 .cu. ft. tuned to 20 hz means you use the three 4" ports as they...

Re: $400 CDN to spend, what do you recommend?

Yes, the MJ-18M will give you the most output if you don't mind the box size. If you go with the triple 4" flared ports you'll have enough port area that you can upgrade the amp in the future and get...

Re: $400 CDN to spend, what do you recommend?

Do you have any wood working experience? Do you have the tools to make accurate cuts in MDF? If building a box isn't a problem for you then $450 would get you an excellent sub for the money.
