Thank you, it is taking a lot of time and work.

It’s too bad the PVC didn’t work out sorry to hear that.  Myself I have never used 3” only 4” and I never had any problems. But I have never used home audio brand subs only Car audio subs.

I have used 4”ports with 12” subs and come to think of it whenever using 15’s used only slotted ports.

Good luck, if you’re in the area I have plenty of wood scrap I could help you out with. I have a hard time throwing out scarps.

Thanks for the offer. I am sure after I screw up enough cuts I will be able to do the slotted port next. Make sure you pick up a good SPL meter so I will know what those beast are putting out. Next question is are you going to try one in a car?

I have thought about picking up an SPL meter before but I was looking for one that could do up to 170 DB so I could also use it in the car but they are expensive. Is there any brand that you suggest? I don’t want to spend a whole lot. I also thought about getting one that is the program/mic you use with a computer. Do you know if there any good?

I was thinking of trying one sub box in my car back seat but when I finish the box it will be too heavy to transport it, so will see. I have a Memphis 1500 class D amp which I could use. I have it running two 12” soundstream SPLX subs.

I have never tried the one for a computer but would like to. I have one of these (http://www.parts-express.com/pe/showdetl.cfm?Partnumber=245-262) and it works pretty good but only goes to 130db.

My favorite for quick test is the old Radio Shack Analog meter.

My personal favorite is the Phonic PAA 2 but it is a little expense.

Okay cool thank you. I will keep them in mind I am still looking around to see what the best software is out there. I would like at least 150 DB In the price range of $150 with a mic.

I have found this software for the computer but I am not sure how much it would cost for a mic. Do you have any idea? If I understand it right the mic is what determines the DB?

I would be afraid to suggest a mic because it is a little out of my knowledge range. As for software this might be about the same as what you are already looking at.

I have the boxes complete with the ¾” MDF and I have been testing it out using mutable DVD’S and song to make sure I have the right sound that I want.  I have the subs downstairs in a remolded basement and since the floor is cement you don’t get the full feeling of the floor shaking but everything upstairs dose, you can feel the bass when in the room on your clothes.

For using a small box ported it sounds amazing, but I am still questioning myself if the box should be bigger. I have been thinking of adding 1 C.F would there be a difference that to the human ear could tell and would it be worth my time to add to the box?
That would give me 3.5 C.F @ around 28 Hz. It is now 2.65 C.F @ 32 Hz.

I am so used to working with car audio in a small area of volume with the pounding bass at your chest. I have placed the subs in opposite areas of the room just to get an idea and I know the placement in different locations can make a difference.

Be sure to try firing the sub directly into a corner.  That can make a HUGE difference in some rooms.

Be sure you have music in this low frequency range (28hz - 32hz) before you invest time and money building a box to reproduce it better.  Lots of old time stories out there about bass resonator chambers being built under the floors in homes only to never have them fire because no recorded music had notes low enough.  I've always considered the lowest note in most rock to be around 40 hz, but I do have exceptions (although I can only think of one that goes below 32).

... aside from the SACDs of Pink Floyd and a few DVD concerts, this is true, more often than not.

The best lows I have heard are mostly recorded live during classical music performances and include heavy percussive crescendos made from enormous bass drums which barely fit into semi-trucks.

Rockers are more into protecting their massive investment in sound gear and most often they roll off the lowest low frequencies, just below the bone sensing frequencies in the 30Hz to 60hz octave. Usually, if they can make the back half of the house feel fifty Hz in their last meal, they are satisfied.

With gating, compression and delay enhancements so rampantly used in these productions, it works, in the heat of the moment and everyone leaves with their ears ringing.

Thank you Dan & Dirt,

I will take that into consideration since I don’t really want to put more time than I need into this build and cut to re add for C.F. I will put the boxes closer in the corners with low Hz playing.

I had the boxes about 2 feet from the corner I bet that will make a big change.

I could always try acoustic foam inside maybe to help. I will give an update with my progress when I try it out.

I did not really help you much BH, but if I was living in an apartment with no neighbors and had limited space, I would go with a twelve inch Deathbox, because the one I have built is miles ahead of any "magic cube"  type "subwoofer"  I have ever seen.

If I had room to place one discretely and the money to power it properly, there are few enclosures that can top a plain old fifteen inch Housewrecker. The four I have built were all quite successful, (eight inch dual driver,  fifteen inch quad and eighteen inch quad, then an eighteen inch dual driver using crummy forty dollar drivers from Parts Express CloseOut listings- each one exceeded my expectations which were quite high from the start)

Do you have the room for a Housewrecker or are you limited on space?  This is the main question. Very few enclosures can approach TeH Performance of a Housewrecker, but they are big as hell!!

My space is a little limited since I have a pool table in the room but my entertainment center is recessed in the wall so that gives me some room.

I have thought about building the HW with my subs but I know it would be very heavy so I didn’t really want to deal with that issue also when I plugged in the numbers with my program (Bass-box Pro) it was giving me 55 Hz rang which I was not looking for, but I thought about buying an 18” Soundsplinter to try out in the HW I think that would be a good choice of sub.

I also own 2-12” Soundstream SPLX quad coals subs that I think I am going to take out of my car and try out building two death boxes  that was going to be my next project when I am finished with the wedge.

I agree. The HWK is a beast in pretty much all forms but as DD said "BIG AS HELL". A definite drawback when space is limited. Are two enclosures better than one when it comes to tuning? I think so but others might not. Pretty much all set ups will have a drawback, it's just finding out what you can live with and still be happy.

I am getting ready to move out the WO410 and put my HWK15 back in circulation. I gotta know what the difference might be between these two titans. Besides the WO410 is due for an overhaul. Where is Chip Foose when you need him?

I have added some Pics with the oak wood.

The next step is to will be to stain and paint the inside of the box.

I will also be making a grill to cover the port and the sub opening,

Enjoy!!

VERY NICE !!! Can't wait to see the final results. As for my build, it is kinda of stalled. I am thinking of stepping up to a better subwoofer, instead of using the Series II woofers. Don't get me wrong they work great but I think a sub with a little more X-max(+18mm) would perform better in the Half-Wedge set up.

Again, that is a great build you have going on and keep the pics coming.
