As said after screwing fill with filler leave a couple days and sand flat.
Make sure the box is flattened as good as otherwise any marks will show.
You can use spay glues cut each bit to about an inch over each side then away you go.
If you're willing, the PSW10 can offer you an excellent learning experience especially since your needs are for 95% movies. Hook it up to your system, all it needs is a RCA cable from the receiver to the sub amp. Watch a few movies known for low frequency content, get a feel for the low frequencies that it can produce, which will be non existent below 30 hz.
Build your Phoenix Gold sub and watch the same movies. Your Phoenix Gold subs are capable of true 20 hz extension, the difference will be night and day. Search the house for the Polk, it will be found hiding somewhere. :bigsmile:
You bet. I was suprised by the "low frequency" content. Expected more output at the upper bass freq, got more at the bottom. I have a feeling my opinion of "low frequency" is gonna change when my build is complete.
Hey Mike, getting close to build time and a couple questions are on my mind. First, the wife demanded the smallest enclosure possible, so I went with the 6ft^3 20hz boxes. I managed to get the ok for both subs . After factoring in the cost of the laminate and mdf, I realized that these enclosures may be around a while. These Phoenix subs are old, but never installed. What if I build these and the subs suck, or fall apart? Can you recommend a current, affordable driver that likes a 6ft^3 20hz box?
Second question, trying to keep these 6 cube boxes as small as possible, and wondering if hardwood bracing inside an mdf cabinet is ok? Lets say I used oak bracing. What would a minimum total cu ft of bracing add up to and still be effective?
Here is my plan. Allowed .2FT^3 for the driver based on the spec sheet, and about that much again for bracing. Will be adding a second layer of baffle over the front to flush mount the sub.I think i was able to lower the tune a little more by lenghtening the back port board, but that reduced the available box volume for bracing a little also. Hence the question about minimum bracing and or reducing the size of said bracing by material selection.
Tweaked a hair to lower the tune a little. Hoping .25ft^3 is enough bracing. MikeP, your thoughts? Dont have a clue if it matters, but it will be oriented like the picture, on its side. With a .75in thick laminated top, 2in larger than the box it self, layed on top of the fully enclosed box. Trying to match exsisting furniture design.
Cool, now I should head back to your enclosure volume calculator and see how much volume that frame with a 3in x .75in size will occupy, correct? If under .24, I can add more bracing, if over .24, I need to increase the box volume a little, and port length to get back to 6ft and 20hz, correct? Or leave it alone if its within 10%, as I think I've I read you tell other rookies in the forums?
This is a continuation of my modest build that you can read about over here.
I chose these drivers because of their compact size requirements, expected impact and relative cost. I have an odd shaped room and wanted more output to work with than not enough, so I bought two.
So here's the...
I built in-floor sealed subwoofers consisting of 8 x 8" drivers each (Dayton Audio DCS 205-4). Those were the only 8" drivers which I found to fit in the subfloor cavity with a box built around them. Each sub has the cone surface area of 2 x 15" subs and 1 x 15" sub displacement. The drivers...

Hello guys i'm new here i want to say that i'm sorry because of my bad grammar if there's any ( im not from the us uk or australia ) i'm looking to build a 8x ultimax 18" setup, i dont really know which boxes to get so i'm looking for advice, they are mainly going to be used for home theatre...
