HERE is the owners manual for your sub.

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

If looking for accuracy, build sealed.

You dont have enough depth for an isobaric setup.

using the maximum dimensions given, 8x13x41, the volume of the biggest enclosure you could make (assuming 3/4" MDF material) is 1.7cu ft.

To tune this 1.7cuft 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.

Just trying to find out about an eko violin bass model 995 serial no 93377


The Eko Model 995 Violin Bass Model Electric Bass Guitar (1965) was made in Italy, serial # 93377 is a sunburst polyester finish, laminated maple body, laminated maple neck with ebony fingerboard. One of the enduring 1960's oddball bass designs and an American garage band favorites. This model was extremely popular in Los Angeles around 1966- this style bass was used by used by Love, the Standells, the Music Machine, the Grass Roots and many others. Yours is a very early example with some unusual early features include a truss rod adjustment at the headstock, the pickups are the earliest style with multiple magnet poles, the bridge is a compensated wooden unit seen in the '65 catalog. A very cool bass and a bonafide 60's Garage Band classic! Overall length is 44 1/4 in. (112.4 cm.), 13 1/8 in. (33.3 cm.) wide at lower bout, and 2 1/4 in. (5.7 cm.) in depth, measured at side of rim. Scale length is 29 1/2 in. (749 mm.). Width of nut is 1 5/8 in. (41 mm.). A very nice collectors item.

I unplugged my rca cables from micropro 4000 and it made a loud boom. Now it no longer puts out any bass. I pushed on the sub and it feels good. The sub powers on just no bass.


Open the case and check the resistance value of the actual speaker - should be around 8 ohms. If it doesn't get a reading, then it's bad.

How much air space is need for a sealed encloser


are you sharing the air space or building a divider to give each driver its own air space

these speakers or not made for low end bass these woofer are meant for mid bass high bass
  • 6.5'' High Power Subwoofer
  • Non-Press paper Cone
  • Specially Treated Foam Edge Suspension
  • 1.5'' High Temperature Aluminum Voice Coil
  • Magnet Weight: 40 Oz
  • Impedance: 4 Ohm
  • Fs: 80Hz, Qms: 4.05, Qes: 1.3, Qts: 1.2, SPL: 87(dB), Vas: 6.8(Cuft)
  • Mounting Depth: 3"
  • Rubber magnet Boot Cover fers are
  • there is only 3 " of mounting depth needed i would build you door pannel out fiberglass a door pod and mount them on the door if you have a factory speaker there . then run to the amp and turn the x-over on to high pass and them use them as a mid bass driver up front for the front sound stage for get about them as a subwoofer get the lanzar 10's or 12's

    i mounted a set of ma audio 8" subs on my 03 s-10 door the speaker fit in the 6.5 location had to trime the door metal and space them out a little cause the 4.75 mounting depth.it worked and then i ran the them in 2 ohm stereo to my 4 channel amp and used the high pass crossover to run them as a mid bass driver works great for me . ma audio 500 watt dual 4 ohms 8" subs each i had 250watts to each sub.

    you could build a small enclosure just big enough to fit the 6.5 woofer you could build a dual camber enclosure like 8wx5dx8h internale air space would be 0.18

    15 wx5dx8h would give you 0.347 share the air space this is internal air space

    When I do a noise test I get no sound out of the woofer. I am getting no bass from the woofer


    These are "decent" quality 5.1 speakers, usually without any trouble.

    Now, to your question, you will not have 5.1 "surround sound" effect with standard sound card, standard sound card will provide only three speakers sound, rear speakers will not connect but bass should be hear. Please switvh power off to the speakers and disconnect all cables from spaekers and connect them for best quality as follows:

    1. Audio from PC, orange, green and black connecting to front right speaker.
    2. DB15 (D-SUB) connecting to subwoofer, subwoofer is serving as mixer, power board, amplifier and connection box, control pod is just cable connection to it
    3. Connect all cables to they respective speakers

    Establish location of the speakers, from experience, in ideal world:

    1. Sub should be on about your knee level or below, about twice your hight from you.
    2. Front centre speaker should be about some distance as sub or bit closer on front and slightly above your head.
    3. Front left and right speakers should be at about 45degree from your axis, at distance of about 1.5 your hight and on the level of your head or slightly below.
    4. Rear left and right speakers should be located similiary to front speakers, on they level or slightly above them, again, about 45degree from your axis.

    Location of the speakers is more actually important than it is assumed, total sound immersion is not possible without proper speakers installation. Head in these instruction meant a location of your head while you are listening to your music or recording not while you are standing.

    In reality... hang them higher than your head in four corners of your room, front centre higher than sides, woofer lower than sides and below front centre, if they interfere with each other - increase the distance. I hate reality...

    After speakers are connected:
    1. Plug power cord in,
    2. Turn all sounds totally down, including subwoofer
    3. Increase sound on PC to maximum, let play any known to you music, tufftuff or bach, whatever, do not bother with metallica as you cannot discredit on it correct levels.
    4. Increase subwoofer volume, holding one hand on the front of the grill till you get some vibration from it
    5. Increase sound on centre speaker, then on sides front speakers till you achieve equality of the sound
    6. Decrease sound volume on your PC to about 60% - 70%
    7. Increse subwoofer volume till you feel sound on your hand in front of the speaker.
    8. Increase sound volume on front/rear speakers as required.

    Hope that short intro solved all your speaker problems, enjoy! if you require any additional help, do not hesitate to answer to this post with request.

    I don't get d true bass quality from my car system...


    Firstly, If it is an open air sub ( hole with mesh in the center of the magnet) no ports are required, and the box should be sealed on the inside with silicone sealant. If it is a closed air sub ( no hole in the magnet) you need a 50mm port about 120mm long Box size will be 13 inches x 13 inches x 13 inches.

    I have 2 12 inch kickers and have a solid box in my mustang. would it sound better if it was ported?


    Kicker speakers always require very large boxes (you're looking at 12 cubic feet for both), when ported. Ported boxes are very sensitive to box size, port tuning etc, so it's probably best to leave it sealed, as they are far more leniant, and sealed boxes are usually 1/2 size of ported boxes. You would get less bass when ported than with sealed (because ported boxes must be bigger to match the sealed ones).

    If you wish to experiment with the bass response of speakers, download winISD, and put your speakers in, see what size boxes give you what.

    REWIRE


    Series wiring of a 4 ohm DVC subwoofer will result in an 8 ohm load.
    See the following diagram.
    The diagram listed has a dual 2 ohm voicecoil, netting 4 ohm, however in your case, the dual 4 ohm sub will net an 8 ohm load.

    Dimension please for enclosure 12w3v2-d2


    Typically you use one cubic foot per sub, so a 2 cubic foot box will work fine. To build a basic one, just a rectangular box, using 3/4" MDF (excellent material for a box), cut pieces this way:

    2 - 25.5" x 13.5"
    2 - 25.5" x 12"
    2 - 12" x 12"

    This will give you an interior volume of exactly 2 cubic feet. Cut your sub holes out of one of the 25.5" x 13.5" pieces.

    Enclosure type


    Sealed box and somewhat large if they are 12's I usually try to get 3 cubic feet overall internal dimensions and generally the inside dimensions will be 13" tall 32" wide and 13"-14" inches deep. with no divider and make sure the box is sealed. Personally I like to phase the speakers backwards. Gives the bass a little more rumble.
