Single ten port

[bland 10+ year member]

I'm going to be building a box for a single ten, and will be using a smple pvc pipe for the port. Should I go with dual 3" or a single 4" port?

Box will be 0.86 tuned to 38Hz

My box for my ten has (2) 3'' flared aeroports and there isn't any port noise at all. But in .86ft^3 the ports will be incredibly long if you have two of them....so take that into consideration.

a 4" in .86 will be long

A single 4" port would be around 24" long. 2 3" would be just over 28" each. Depending on the sub and the amount of power that you're running, a single 3" with flares might be plenty of port and will be such smaller. Using a single 3" port with a 3/4" flare radius would only require a 9.8" pipe between the flares.

Sub will be a mach5 ixl10. I will smooth it out as much as possible, but there will be no flare on the port.

It will be wired on a rockford 3000 amp wired to 4 ohms to give it around 1k . I'll be taking it easy on the sub since this will be my winter setup.

I don't have any experience with the ixl10 yet, but I plan on it one day. But I know for my 10'' BL on 1000 watts in 1.25ft^3, (1) 3'' aero was not enough....once I added the second 3'' aero and made the enclosure bigger it really came alive and had 0 port noise. What vehicle will this be going in?

Subaru forester

Just bought the 3" pipe. Building the box tomorrow.

The sub or the suby? I just ordered it yesterday. Should be in early next week.

i have ran 2 different boxes for single 10's with only one 3 inch port, you dont need that much port area for a single 10, one 4 inch at the most. I have run single 4 on many single 12 setups.

With that power and that sub you're going to want some more port area. I spent nearly a day trying to get the ports to fit in a box for a pair of IXL 10s with enough port area to keep port velocity down. The port ended up about as big as the box and I couldn't fit PVC ports in the truck, much less the box. I was tuning MUCH lower, but a lower tune allows for less port area and moves the high velocity frequencies out of the primary freq range. I was also using less power (less than half that per driver) which allows for less port and I still needed a pretty big port.

You don't need to use aero ports or precision ports to get a flare. You can simply use a router with a large roundover bit and get great results. Glue a piece of wood as a flange on the end of the port inside the box and use the roundover bit on it, too. Using a 4" PVC port in that box with a 3/4" roundover you should be OK with that tuning and power. The port needs to be 20 3/4" between the flares. Without the flares you're going to get a TON of port noise with a single 4" port. A pair of 3" ports won't be much better. With the flares though a pair of 24" long 3" ports should have no problem with port noise.

Not enough port. At 1000 watts of power using a single 3 inch port, you will have a vent velocity of roughly 50 m/s or 17% mach plus. Clearly over 35 m/s or 10% mach, where port noise is noticeable.

In some cases you may be able to get away with using a single 3 inch port with a ten, but that is all dependent on the driver, box alignment and power.

Deffinately at least one 4inch. You will notice port noise on anything less. I would even say 1 six inch if you plan on running alot of power... IMO

Well box is made with dual 3's. Would have taken picks but I left my phone at home. I'll keep everyone posted on how it goes.

Now waiting on the sub.

You're going to have port noise. Be ready for it.
