$300 budget for Driver and Amp. Need suggestions!

[Mike P.]

I thought you were going with 4.7 cu. ft. That is the reason I mentioned using the calculator as a 6.3 cu. ft. box would have been to big.

Here's the file for the Dayton.

Okay, I have to apologize. I am all over the place!!! To clear things up...

1) I decided to go with the 5.646ft^3 box that is shown in WinISD as my cabinet. The dimensions will be 20x37x18

2) I downloaded that Dayton file for WinISD and still can't get the specs to match yours. Are you using a decibel gain or some sort of high pass filter? If so, what specific ones so I can add them. Sorry, I am not too familiar with WinISD so I will need your help.

3) With those dimensions that I just showed you, what kind of internal bracing do you recommend?

[Shicks18]

Any help anyone? At least someone's input about internal bracing? I was thinking of doing 5 pegs of 3/4" x 3/4" x 16 1/2" running through the cabinet at the top and another baffle on the inside.

Will that work well?

2. 300 watts input power, then you add a 2nd order HPF at 17.7 hz. Next add a Parametric EQ with the center frequency at 27.5 hz, a Gain of 1 db and a Q of 1.0.

Window pane bracing is popular, side to side and front to back. The front to back piece would have a cutout for the depth of the sub.

Do you have a link that I could see what your talking about? Thank you so much for your time and patience with me. I am learning a lot!

Edit: Also, how does the SPL Frequency chart of the 15" Dayton HF compare to this SVS PB10ISD? Link: http://www.hometheaterhifi.com/volume_11_4/svs-pb10-subwoofer-10-2004.html

To apply a HPF and also the boost that the Bash 300 amp has, click on the EQ/Filter tab. Click on Add and select Highpass. Enter the numbers as stated in post #14. Click on Add again and the filter will be applied. Click on Add and select Parameteric EQ. Enter the numbers and click on Add. The EQ is now applied. Thereis a tutorial on WinISD here:

Depending on how much room gain you get with the Dayton, it should outperform the SVS.

I ended up getting the WinISD part to work. Thanks.

Back to the Dayton vs SVS shootout. Will there be substantial performance upgrades over the SVS?

I just finished drawing up a blue print of a sealed sub I am going to build. I will be using a 15" Dayton RSS390HF-4 and Bash 300 Watt Plate Amp as my components. The cabinet's dimensions are 20 x 18 x 37 (length x width x height). With internal bracing and components my net cubic feet inside the cabinet will be around 5.7, give or take. Here are 2 pictures of my blue prints:





I wanted to get some feedback on these designs. The quality isn't all that great, I had a of a time getting these uploaded. Anyway, I wanted to make sure the enclosure looked good, the bracing was fine, and that this design will help maximize the overall quality of the sub! Oh yea, the material is .75" thick MDF.

Thanks in advance!

I would suggets that all your braces look like the one you have in the bottom rather than those little stick cross members. Also, I would put another horizontal brace just above the woofer and a pair of vertical ribs (about 3 iches high) on either side of the Amp cutout.

Box size looks about right for that driver, although you could reach excursion limits at about 180W. You could reduce the size of the box some if you stuff it.

Overall, it looks good...I'm sure it is going to rock!

[Shicks18]

Thanks for the input! I am confused as to what you mean by vertical ribs??

Also, I looked at WinISD and it will hit excursion at 250 watts. I will be stuffing the box with some fiberbglass insulation from home depot. How much will the stuffing reduce the driver from reaching excursion?

Edit: Here is the WinISD for the driver:



How will this sub compare to the SVS PB10?
