Quick Overview

A very compact high output design with great off axis performance.

* This kit ships for free *


Availability: In stock

* Required Fields



The Volt-6 has a custom made 6.5" coaxial using the same magnet and motor assembly as the Volt-8 and Volt-10 to give it high output and power handling.  Impressive X-max with a light weight cone give this speaker a smooth sounding midrange even when played at high levels. The Denovo DNA-150 compression driver (tweeter) is installed on the back and fires through a small waveguide in the center of the woofer giving you point source sound and great off axis response.

The crossover was designed to give an even response that not only excels for surround sound speaker use, but also for great front speaker performance. The Volt-6 does quite well in small ported enclosures between .3 and .5cuft when used with a subwoofer. The Atmos version is a small sealed enclosure designed to play down to 115hz, which is perfect for Atmos use. You can use the Volt-6 in your ceiling without an enclosure for Atmos use if needed. For surround sound or mains, you should build the ported models. 


Product Notes: 

If you do not buy a flat pack the standard baffle is 8" x 12" with the single port like the photo shows, but no roundovers on the edges.  All of the Volt-6 models were designed to perform best when paired with a subwoofer that can handle the lower frequencies.  The ported versions can be used for fronts, surrounds, or Atmos.  The small sealed cabinet is only recommended for Atmos use.  You can also mount these in the ceiling without an enclosure behind them for Atmos use if you wanted to.

  • Uniform off-axis performance
  • Near perfect time alignment between woofer and tweeter

Specific Volt-6 Assembly Notes:

A great Volt 6, 8, and 10 assembly thread has been put together to help you build these popular designs.  Click here for all the information and pictures. Your enclosure should be built with 3/4" thick material for the angled surrounds or 1/2" for the standard enclosures and the included 3/4" thick baffle to the dimensions listed under the specifications tab. No internal brace is needed for these due to the panel sizes. It is recommended that you lightly fill the enclosure with polyfill or some type of loose insulation as long as you don't block the ports.


Recommended Tools and Supplies:

  • Quality wood glue like TiteBond.
  • At least 2 clamps 12" wide or bigger.  
  • Soldering Iron and solder unless there is an optional assembled crossover for your kit.
  • Wire cutters
  • Screwdriver
  • Drill to predrill all screw holes.
  • Sanding block or power sander.
  • About 3' of speaker wire to connect your woofer and tweeter to the crossover board.


General Tips:

    Crossover Assembly: 

  • VERY IMPORTANT - Inductors are the parts that look like small rolls of copper wire. Notice that the two ends of wire are silver and have been 'tinned' with solder. Those are the parts of the inductor that you should be soldering to, so don't cut it off to get to the copper colored portion.  Inductors should not be installed directly next to each other on your board.
  • None of the crossover parts have a positive or negative side so it doesn't matter which way they are facing when you assemble your crossover. 16-18 gauge wire is thick enough to use for your crossover or to go from your crossover board to the woofer or tweeter.
  • Your crossover can be assembled on a thin piece of MDF or pegboard if the kit doesn't come with a circuit board.
  • It doesn't matter where you put the crossover inside your speaker.  You could mount it on the outside if you wanted to.  
  • Normally you wire red wires to positive and black wires to negative.  If (and only if) your crossover schemtaic has a note saying 'Inverted Polarity', that means you need to connect the negative from the crossover to the positive on the tweeter and positive from the crossover to the negative on the tweeter.  This is only done on some tweeters, not woofers.

     Screws and Gaskets:

  • Predrill all screw holes with a bit that's slightly smaller than your screws to prevent the wood from splitting.  Most screws are #8 panhead and you can use a 7/64" or 1/8" drill bit.  Overnight Sensations use a #6 panhead so you can use a 3/32" bit.
  • VERY IMPORTANT:  Protect your woofer or tweeter when installing screws because you don't want the screwdriver to slip and puncture one of your components....that will ruin your day!  Consider putting your free hand next to the screw to cover up the edge of the woofer or tweeter.
  • If your kit comes with gasket tape, it should be applied to the back of the waveguide. Peel the paper off the back to expose the sticky side and slowly work it around the perimeter on the back side of the part.  Some woofers will need gasket tape as well.


     Stuffing or Lining the Speaker Cabinet:

  • If your speaker or subwoofer is a sealed cabinet, most designers recommend that you lightly fill the inside with polyfill (pillow stuffing).  If you don't have polyfill, then you can line the walls with 1" - 1.5" thick light weight open cell foam (like acoustic foam) or fiberglass insulation.  You can also use 2-3" recyled denim insulation that can be bought at Home Depot.
  • It's okay to cover up your crossover with the polyfill, insulation, or foam.
  • If you're using a ported enclosure you should lightly fill the cabinet with polyfill and be sure not to block the ports.  If you do not have polyfill then line the walls with 1" - 1.5" thick open cell foam (like acoustic foam), 2" - 3" of denim insulation, or 2" - 3" thick poly batting.
  • Some of the speaker designers like to lines the walls of their ported enclosures with a 1" - 1.5" acoustic foam, and then lightly fill the remainder of the cabinet with polyfill.  If this is a required method, it will be listed at the top of the page under 'Assembly Notes'.

Frequently Asked Questions:

* Do I need to cut the port to a certain length?  Answer:  No, use them full length.

* Where does the tweeter go?  Answer:  It screws into the back of the woofer.

* Do I need to use a subwoofer with these?  Answer:  Yes, these were designed to be used with a subwoofer.

* Where should I put the assembled crossover?  Answer:  The crossover can go anywhere inside the cabinet as long as you don't block the ports.

* Does the standard 8" x 12" front baffle fit the angled flat pack?  Answer:  No.  If you're building angled cabinets, the flat pack is highly recommended because they aren't easy to cut yourself.
