Yup, it's amazing what you can knock together with an old washing up liquid bottle and some sticky-backed plastic, so why not take a break from building that Warhammer Blood Marine battle fortress and try some of these bad boys instead!?
Paul C. The long awaited second part. Name: Disco Stu Email: studarl hotmail. Would be good for compact but loud bass guitar or small compact bass bin for PA. I dont usually like eminence but this driver is an exception to the rule seems to work wonders in any box! Email me if you're interested Stuart.
Name: stuart Email: studarl hotmail. Trying to answer a few questions at once. For all the people who want folded horns goto www. Again look on speakerplans for the bandpass design sub.
Id usually recommend Precision Devices for bass but the 21" PD doesnt work as well in a reflex as the beyma 21" does. Finally to the person who wants better sound from either a full range or bi amped system ive never had any problem with muddy sound when using a full range enclosure. May i suggest you try a different enclosure i find a single 15 and compression driver works well with about w a side for a smallish venue. Also try using a bigger rig for the bass player onstage if you can, meaning you have to put less bass through the main PA.
You should get a better sound that way. One other tip is use good drivers with strong magnets like PDs and Beyma and try not to use Eminence if you can help it. Eminence are ok if you're going to underpower them but at the most only put their rated value through them or they wont last very long. Good luck Stu.

If there is anyone out there who have built one of these scoops and maybe used EV DL15X drivers inside, can you let me know how it sounds I have two of these drivers lying around in my room. I'm dont want to spend the money to build the bins to find out that it sounds crap. Name: John T. Foley Email: falcore ix. Great site. Any plans to put out plans for contruction of Guitar and Bass cabinets?Eminence is often asked to provide cabinet plans for our woofers.
We do not provide drawings with specific cabinet dimensions and details, but we do offer cabinet volume recommendations. The reason for doing it this way is because we do not know what size or shape cabinet you need or want to build. Unfortunately, one magic, do it all enclosure for every speaker does not exist.
There are trade-offs involved in cabinet design. You must decide how your speaker and cabinet should perform to meet your needs.
The main concerns are mechanical power handling how much power a particular speaker will handle in a specific cabinethow low the cabinet needs to play, and how much output you will need. From the Eminence cabinet designs, the box should be built to the Vtotal specification. This is the internal volume of your cabinet with no speaker in it. If the cabinet will have bracing and you want to be precise, be sure to account for the volume of the bracing and add it to the internal cabinet volume.
No need to worry about the volume of the speaker and ports! That difference in volume is represented by Vb and has already been calculated.
If you are looking at a ported or vented design ported and vented have the same meaninground vents are specified in most of our recommendations. The number of vents to use is given. The diameter of the vent is represented by Dv. The length of the vent is represented by Lv. Some of our recommendations do actually call for a rectangular vent shape. In this case, Hv represents the height of the vent, Wv represents the width, and Lv represents the length or depth that extends into the cabinet.
In regards to vent placement, Eminence recommends symmetrical placement around the speaker. Some people may also consider rear porting a cabinet. This is acceptable, but keep in mind that most of the sound around the resonant frequency of the cabinet will be produced by the vent. Thus, a lot of your bass will come from the rear of the cabinet.
You need to consider how you will use the cabinet and where it will be placed if you consider rear porting.The bass cabinet is the box with the speaker. The materials used to make a bass cabinet do not seem that impressive. But, there is a lot that goes into designing the cabinet ensuring everything works together and creates a good reproduction of your bass tone.
The design is a big part of what you pay for in a bass cabinet. The maddening part of shopping for any bass gear is making sense of what is hype and marketing jargon and what is important. Plus, every manufacturer uses slightly different terminology. The enclosure is the housing, or box, of the cabinet.
The bass cabinet enclosure will experience a lot of vibration from the bass you pump through it. A solidly constructed enclosure is essential for a bass cabinet.
Most enclosures are made of plywood. Good quality plywood is important. The type of plywood has a limited effect on the overall sound of the cabinet. You will sometimes see the term void-free plywood. That just means the plywood is solid though and through. For really heavy ones, look for wheels casters. The corners should be tough and protected, too. The corners will experience a lot of abuse. You may see terms like stackable or interlocking corners.
This helps you easily stack two cabinets together. Some cabinets are sealed meaning no air leaks in or out of the enclosure. Most bass cabinets are portedor ventedmeaning the cabinet has an opening where air can travel in and out.
Sound is essentially moving air. As the speaker pushes air in front of it, the rear side of the speaker on the inside of the enclosure is sucking air into the enclosure and vice versa.
Having the port helps the speaker work more efficiently which means it requires less amp power to drive it. Ported cabinets, as a result, often get a better low-end response. In a sealed cabinet the speaker cannot suck any air in. That makes the speaker work harder. Sealed cabinets need more power to achieve the same results. Some bassists like the sound of a sealed cabinet claiming they have a punchier sound.
You will have to decide with your own ears. Most of your bass cabinet options will be ported ones.The first system considered here is a 8x10 modular system, which is really four 2x10 cabinet boxes stacked. This is in part based on emulating the Ampeg 8x10 bass speaker system for the famous SVT bass head. Some of the original systems had a 32 ohm cabinet, which indicates that the speakers were 4 ohm and likely wired in series.
This of course was designed to match the amplifier's output transformer. Also, the Ampeg speaker cabinet used Eminence 10 inch woofers, and the cabinet was divided into 4 compartments, with two 10 inch woofers in each section, which would handle 75watts at the full output of the amplifier. Each 2x10 compartment was an infinite baffle type system i. If you have never used one of these systems, you have no idea what a great bass system these are.
They are the Holy Grail for most bass players. Even a "not so great bass" usually sounds much better on one of these systems. This modular speaker box design of mine gets you half way there!
The 4x10 Ported design above, is again not my specific design, but is just one possible way to build according to the specifications of the Eminence speaker designer. The folded Corner Horn Klipsch Design is my favorite. I have built three sets of these boxes, and they are not for the novice builder.
But they are very rewarding if you know what you are doing. You can actually use a variety of speaker sizes for drivers in the bass cabinet portion. As I have experimented with 12, 15, and 18 inch woofers in these cabinets.
The most important factor seams to be making sure that the resonant frequency Fs of the woofer is significantly below the lowest frequency of the horn itself F3which is 40hz. By experimentation, I have found that even woofers with Fs of 36Hz, are not low enough for this system.
This is likely due to the physical loading of the woofer cone by the air mass in the horn itself. Most designers, familiar with these systems, recommend using 4 ohm woofers, because of the air mass loading, which changes the impedance of the speaker to a higher number, approximately 8 ohms. There are number of interesting facets about these speakers: 1 the are not linear in there reproduction of frequencies, since they have two very notable spikes at 80hz and hz, 2 No insulation is needed in the space behind the woofer, since it is so odd shaped, 3 The frequencies developed by the entire system are mechanically delayed and approximate the effect of BBE sonic maximizer, where the highest frequencies are heard first, followed by the mid range, and then then the bass notes.
This delay is in the single digit milli-seconds and is not generally perceived most people. What a beautiful site! Back to the Speakers Page.Apr 6, 1. Mar 28, Raleigh, NC. Does anyone have experience building cabinets?

Make sure ports are LESS in diameter than the speaker.
Just for starters Good Luck, smo. Apr 7, 8. Don't bother trying to build your own if it's going to be a simple box. You can't build one for less than what you can buy one for from Avatar, because you can't buy any of the components for anywhere near what Dave can.
DIY savings only come from savings on labor costs, and since the total labor time involved in building an Avatar is perhaps four hours there's not much there to save on. DIY speakers only make sense if you're going to build a more sophisticated labor intensive design, one which you couldn't afford to buy at retail just for that reason.

Bass guitar cabinets usually require the most materials and the most calculation in order to achieve a sturdy cabinet that can handle the low frequency demands of the bass guitar as an instrument.
This will be the main baffle of your speaker cabinet where the speakers will be mounted. This will create the frame for your speaker cabinet. On the first 32 x 26 inch cut of plywood you made, from the top right hand corner, measure one foot from the top and one foot from the right, trace a perfect 10 inch circle revolving from that point.
15" speaker bass cabinet contruction plans
Measuring from the top left hand corner one foot from the top and one foot from the left, trace a 10 inch circle revolving from that point. On the bottom right and left hand corner trace two 10 inch circles pulling 19 inches from the bottom and one foot from each side. Below the circles, trace two 4 inch circles pulling 5 inces from the bottom and one foot from each side.
Cut out all of these circles neatly with a jigsaw or router saw just outside of the line to give a tiny bit of room for the speakers and port tubes. Spray paint this piece black. Cover the four sides besides the baffle in tolex by tightly wrapping each side like you are wrapping a present and stapling it off tightly inside of the cabinet. Set the cabinet on its back. Carefully place all 10 inch speakers inside of the four 10 inch holes in the baffle and attach them with the four speaker mounting kits.
Fit the two 4 inch wide port tubes into the 4 inch holes below the speakers and install them with the small mounting screws. Cut four 18 inch lengths of speaker wire and attach them to the positive and negative contacts on each speaker.
Cut the appropriate rectangle shape needed to fit the speaker jack into the remaining back plywood piece. Wrap this piece in tolex.
Attach each wire from each 10 inch speaker to the speaker jack and then solder it with a soldering iron. Screw the back panel onto the cabinet. Finishings can be added to give your cabinet a more professional look, such as cabinet corners in plastic or shiny metal, sanding down the corners to create smooth edges, decorative piping under the tolex at each corner of the front of the cabinet and a frame that fits in front of the baffle covered in a decorative grill cloth.
Be extremely careful using any power tools; have someone help you feed sheets of plywood through your table saw to avoid kick back which could lead to serious injury. Always use safety goggles, gloves and ear plugs when using power tools. Dustin Covert is a freelance writer for the arts and entertainment section of the North Park Press in Chicago.Bass Cab Build

Things You'll Need. Mount the speaker jack onto the back panel with provided mounting screws. Attach four rubber feet or caster wheels to the bottom of the cabinet. About the Author. Photo Credits.A bass speaker cabinet is a lot like a guitar speaker cabinet but is usually much more squat and is designed to direct and concentrate sound.
It is not an amplifier though an amplifier can either be installed in the bass speaker cabinet or used separately. The speaker outputs the sound from the bass while the amplifier controls how the speaker will handle it.
The bass speaker cabinet is there to make the sound crisp. You can place the amplifier inside the bass speaker cabinet if you choose but the extra space can dull the crispness of the sound.
You can buy a bass speaker cabinet at your local musician's store but building one is not difficult or expensive but is a lot of fun. This article will show you how to make your own bass speaker cabinet.
The speaker is attached to a speaker board which is in the inside of the bass speaker cabinet. Cut a piece of pine that is large enough to contain the speaker plus two inches on each side. Remember that you want a bass speaker cabinet that is longer and shorter; not tall and thinner. Draw a circle the size of the speaker with the compass and cut it out with the jigsaw. Mount the speaker to it with screws and set it off to the side. The bass speaker cabinet has to be large enough to hold the speaker board.
This space prevents the speaker from overheating. Once you have the front of the bass speaker cabinet you will draw and cut out a hole for the speaker as you did in Step 1. Cut the screen to size and glue to the front piece of the bass speaker cabinet.
Cut the foam to size of the inside of the cabinet. Glue and then nail foam pieces onto the top, bottom, sides, back and to the back of the speaker board.
Cut away the foam where the input jack hole is. Place the speaker board on top of the front piece so it sandwiches the mesh and then nail in place. Build the bass speaker cabinet by fitting together every piece except the back. Use a combination of glue and nails. Wire the input jack to the speaker and feed it through the hole in the back and screw in place. Nail and glue the back in place.
