L7 15 not sounding right.how do I wire the sub in a ported box


It's quite simple, positive from amp to positive of speaker, negative to negative. Make sure it's getting sub frequencies only and not full spectrum signal. Next (if everything checks out so far) see if the box dimensions and ports are correct for your sub. The sub and box combo will have lots of factors when considering tuning of the box and port size. You can find all sorts of info on the website for your sub. Qtas, max excursion etc etc etc. They might even list a few total volume and port dimension sizes for the sub you have and your taste in music. It's quite a science to get it right. More than buying a sub and buying/building a box to get great performance. When you get it right though... music to your ears (and chest)

Would a 10ZX750.1 amp be alright on a Single Solobaric L5 10" inch in a ported box???


yes, the 10ZX750.1 is capable of running two L5's at two ohms in either a ported or sealed box. Just be sure to wire it up to suit your needs correctly (if you need to know how i can help) and make sure that your box dimensions match what kicker specify. the L5 is actually one of the subs that kicker reccommend for that amp.
Hope I helped , and please dont forget to rate.
cheers

Hi i have a 15"w3-d4 jl audio sub,can anyone tell me what size antype box i should use ie sealed or ported and the box dimensions


Hi,
I've had a look at the JLaudio website and they recommend 2 box designs, a ported and a sealed.
The sealed box needs a volume of:
2.125 ft3 or 60.2 litres.
To get this you would need to build the box to these dimensions:
22" x 16" x 14.75" or 559mm x 406mm x 375mm
The ported box needs a volume of:
3.50 ft3 or 99.1 litres.
To get this you would need to build the box to these dimensions:
24" x 19" x 18" or 610mm x 483mm x 457mm.
The port needs to be:
3.0" x 10.9" or 76mm x 277mm.
The enclosure recommendations listed above are external dimensions which assume the use of 3/4" (19mm) thick material. If you are using 5/8" (16mm) thick material, subtract 1/4" (6.5mm) from each dimension. Do not use any material with a thickness of less than 5/8" (16mm) as this may compromise the rigidity of the enclosure.
• All enclosure volumes listed above are net internal volumes! Driver displacement, port displacement and brace displacement must be added to obtain the final gross internal volume. All enclosure dimensions above have already taken this into acount.
• When using two subwoofers in a common enclosure simply double the required volume and, in the case of a ported enclosure, use two times the recommended port(s). Likewise, when using three subwoofers in a common enclosure simply triple the required volume and, in the case of a ported enclosure, use three times the recommended port(s).
• We recommend the use of this speaker in a bi-amplified system using high-quality satellite speakers and a high-quality amplifier. We do not recommend the use of this subwoofer with a passive crossover (coil), as this type of device will adversely affect performance.
As you can see it all depends on the space you have available, whilst the vented box will give you a more efficient bass responce especially with the low range frequencies.

If you to go and look at the information about your sub woofer and find out all the information about building or buying the correct enclosure then this is the link to the pdf file I found:
The enclosure info is on page 3:
JL AUDIO 15W3 Tech Specs and box info.
Warm regards

Kicker 8 inch l5 problem!


Possibly. Actually there are sub rings you can buy to convert a regular box over to one that will accept a square sub without cutting the whole out in your box to make it square. The airspace may be lacking a little bit.

What is the recommened air space for kicker comp vr sealed do you know the specs for building a sealed box


Really it all depends on how you want them to sound, and to be set up. There really is not specific air space, but there are general air spaces that work, and some times the manufacture will list some specs for different set ups. It also depends on the size of the sub, which you did not specify.

Kicker recommends as follows.

0.4 cubs per sub for a compact box, and 1.8 for an SQ box. SQ stand for sound quality.

So if you want a small box, do .4 per sub. If you want a better sounding box do 1.8.

Rule of thumb and something to think about.

The more air space in the sub, the less power you can run, the less air space, the more power you can run.

For example you can run 200 watts RMS per sub at .4 cubes, but only 140 watts RMS with 1.8.

As well, the smaller box will be louder, But not sound as good.

Box dimensions for 15 in cerwin vega


do you want the box ported or unported (holes or no holes) if you don't got a lot of room than you dont want a ported box. keep in mind the box has to have the correct amount of cubic air space or you could seize your sub... if you're building it make sure you use OSB board (oriented strand board) or MDF board(medium density fiber) your sub needs .7cubic feet of air space in an unported box

Box dimensions


I've Got The Same Subs, I Got A Formula On The Net, Its Dimension Is Aprox 9 D X 24 H x15 W.
Although I Have Them In A Home Made Ported Box I've Made, Its Dimensions Are 8 D X 23 H X 17 W And Its Sound Pretty Damn Good. I Have A 2 Inch Round Port X 6 Inch Long. The Formula Says I Should Have A 3 Inch Long Tube.
