SOURCE: which speker box should i use for alphasonik

If it is an open air sub ( hole with mesh in the center of the magnet) no ports are required, and the box should be sealed on the inside with silicone sealant. If it is a closed air sub ( no hole in the magnet) you need a 50mm port about 120mm long Box size will be 13 inches x 13 inches x 13 inches

The 6.5 foam ring


This is a very common problem and I don't know why companies still use foam.

The ring is called the "surround" and the problem is known as "surround rot".

There are 3 fixes.

Replace the entire driver. (most expensive)

Recone the driver (tear out the old cone + surround + spider and glue in a new one using the old basket).

Refoam the surround. (replace just the foam surround).

I know of one location in my hometown (Ottawa Ontario, that does re-foaming and people that do this are few and far between).

If you can find someone to refoam it go that route, failing that do a recone. A recone will last just as long as a new driver.

Hope this helps!

Cheers,

Which is the size of the box just for one PSW912 to mount


I used to compete with these subs, and found that for street beat 2.7 cu ft ported tuned at 38 hz was the best for this sub.

If using for max SPL your tuning will be much higher, like around 55 hz. But that all depends on the vehicle.

THE WOOFER RATTLES REALLY BAD WHEN ANY MUSIC OR VOCAL IS RUN THROUGH IT, WE HAD THIS PROBLEM A FEW YEARS AGO AND REPLACED THE WOOFERS IN THE FRONT OF HOUSE MAIN PA SYSTEM, THE VOICE COIL WAS BAD.


you can have the woofer reconed, refoamed or replaced. if the voice coil is bad then you can only refoam or replace. if the problem is that the poly foam surround has dry rotted, then it can be refoamed or you can purchase a DIY refoam kit. there are also many replacement woofer options.
