### What is the best enclosure for the diamond audio tdx12d2 subwoofer

Personally for a sealed box i would go with at least 1.2 cubic feet inside volume.
A 19" x 14" x 17" box will give you a volume of 1.6 cubic feet (most common).
You can do the math by H x W x D then divide that # by 1728 (for 12" speaker) to get your enclosure volume (cubic feet).
The best enclosure depends on what your looking for in bass response.

### What r the parametric specs for the ma audio hk15x2

Fo (Hz) : 29.581 QMS : 3.965 QES : .517 QTS : .457
VAS (liters) : 147.723 REVC (Parallel-Ohms) 1 SPL @ 1 watt/ 1 meter (dB) : 90.6 X-Max Linear peak-peak (mm) 70 LEVC @ 1kHz (mH) : 1.043 Enclosure Volume (Sealed) : minimum 2 cubic feet Fill Required % : 0 3dB down point (-3dB) : 43 maximum sealed: 2.5 cubic feet n fill required: 39 at 3 dB down point Enclosure Volume Ported Vented (cubic feet) : 5.0 Vented to Hz: 35 3dB down point (-3dB Hz) : 28 Square port area Sq/In : 80 Port Length : 13" Power Handling : 2000 Watt RMS & 4000 Watt Max. Make sure to use MDF for the enclosure and use 1 inch thickness and use braces as well. This is a beast of a sub woofer. So give it the proper power it needs and make sure that your box is very solid in construction. If installed correctly and given the right power, this sub woofer is bound to put a smile on your face and rattle your bones. I hit 142dB with only one of these subs and im sure if i gave it more power i could hit the 150dB range. DON'T FORGET TO GIVE IT THE POWER IT DESERVES. Have fun dreamsystems.

### What size should i make the enlcloser

If looking for LOUD, ported enclosure is the way to go.

If looking for accuracy, build sealed. You will need approx 2 cu ft
To tune this 2 cuft box around 50Hz, you need (1) 4" round port 5" long.

MTX recommends an enclosure of 2cuFt ea. You will only be able to use 1 subwoofer in this application.

Even a sealed enclosure is recommended 1.25cuFt.

You can shove 2 in the vented enclosure, but you may not be happy with the outcome

### Should I use a vented box or a non vented box for my ALpha PSW412

Well, First you need to figure out a few things. How much room you have is one main consideration, If you go with a vented (ported) enclosure or band pass (see below) than you will need more room than with a seal enclosure, If you really have no room you can mount them " Free Air" which is mounted on a board and fired into the back seats, the Truck acts as the enclosure.
Now the type of bass you want is another consideration. The best enclosure for maximum bass is a bandpass box. It is 2 subs facing each other with one side fully enclosed and the other side ported. This is best for deep powerful bass but the enclosure can be rather large. Vented boxes are second best (In my opinion) they give you deeper bass and more power than the sealed boxes. Sealed boxes give you less power from your sub and are a little flatter. Some say that the bass is more accurate and tighter , depending on the type of music you play. Rock you would want a tighter bass(sealed) and hip hop or techno style you would want a deep bass(ported). Lastly you have the free air which gives you the least amount of bass and is usually rather flat sounding. If you have the room go for the band pass box, if room is an issue than go with a sealed and specifically design box for you vehicle. Alot of places design boxes for almost every car out there. Just make sure that have a well designed box, It makes a world of difference, than an improper box.

### I own a hk 12x2 and put it in a 2 cube inch sealed enclosure. will it sound better in a ported or bandbass

ported is the loudest your going to get as you get sound from the front and the rear of the sub compared to hearing only one side in a sealed or bandpass box.Bandpass boxes are very loud near there tuning frequency but tend to sound offish at tones that aren't near the tuning frequency. The same with ported boxes and the bass will tend to be a little sloppier compared to the tight bass of a sealed enclosure- it comes down to your musical preferences- more sound at the cost of clarity and loss of power handling capability or tighter cleaner bass with added power handling.

### I just bought 2 JVC CS-DX30 12" car speakers. What kind of box am I supposed to get sealed? vented? ported?

You can put these in either a sealed or ported enclosure, not vented. Your box choice depends on what kind of bass you are looking for and the power of the amp you use to drive them.

A sealed box will give you more accurate bass reproduction but will require more power for a given volume. A ported box will be louder at the expense of sounding somewhat "boomy". You should really listen a pair of 12"s in each type of box before you make your decision. Some people don't like the sound of ported enclosures, others love it.

I'd recommend one of the enclosures here:

### Best sub For RF T10001

There is no "best" its a matter of opinion, and fabrication. I have installed \$75 subs in the properly fabricated and tuned enclosure that sound like \$300 sub in a pre-fabbed enclosure. For volume, you will need a vented enclosure. For sound quality, a small sealed. Both have pros and cons. SoloX 10 is 2500W rms 5000W peak.
Kicker is plastic. Solobaric may be your best choice in such a small space, however soundsplinter makes an 8" RLi sub that will kick a\$\$ in the proper enclosure.
When looking to buy, compare x-max : as this is the linear distance the cone will move. More movement = more air displacement = more volume.
