As always you will find hundreds of products including speaker kits, loudspeaker drive units and subwoofer amplifier kits plus we provide suggestions and advice designed to help you get the very best from your Hi-Fi and music. It’s not even really a project per se, these are like standard issue audio components that anyone with a decent hifi stereo or home theater (i.e. not a low end pre packaged HT in a box) will have handled… The components that Jerry selected are abfor as good as you can do for $150 too, so if you just wanna jump in I wouldn’t even bother with any further research.
To fix it, I modified the plans by making the baffle a full 7 1/2″ instead of the 6″ called by the original plans and making the sides 13 1/2″ versus the 14 1/4″ called by the original, you can see the modified plan below and the original plans here This makes the baffle much stronger by giving you an additional 3/4″ on each side yet does not change the internal volume of the speakers.
The easiest way is to use super-thick wood and many braces inside, but you can also make a double-walled design filled with sand, cement or even lead shot, or line the panels with lead sheet Many super-expensive speakers have cabinets like this, but retailers hate them; do-it-yourself lets you have super-cabinets with affordably-priced drivers in them.
Over the years, I have asked the question of what ratio is for DIY vs Comercial and what I have found is that if we EXCLUDE our time, EXCLUDE equipment to build speakers then its about a 5 to 1 ratio or 4 to 1 ratio….meaning if you spend $200 on DIY parts you have a good probability of making a pair of speakers that will equally perform to a set of $1000 commercial speakers.
I think the recommendation to buy a kit if this is one’s first build is crucial. The ONLY thing in DIY that might turn off window shopping speaker buyers is that we do not go out and audition DIY speakers. It keeps the crossover away from the vibration and magnetic field of the woofer, makes removing and fiddling with the crossover without de-soldering a doddle, and it allows access to a part of the line otherwise closed to you when the box is glued up. Soldering the crossover was very easy, IPL provide a schematic and it has few components.
As you can see in the pictures, the speakers have become about 6 feet tall and as a result the the ribbon tweeters and the Fostex full-range drivers had to be tilted down (as in the over $100,000 Wilson Audio’s Alexandria 2 and Maxx 3 speakers). We have found the perfect ingredients for such a kit and Marco from BlueAmps used his black magic to design a high quality speaker cabinet which is so good, that we even stopped offering our Camper 112 cabinets because the new Camper Plus cabinet offers even better value ! Cut out your tracing and use it as a template to mark the box surface for cutting.
I was checking out the Solen site – Biff- I need a new tweeter for my Paradigm CC370 center speaker- as long as the dimensions are equal and the tweeter matches the hole, should I be alright ordering it- all of the 26mm tweeters seem to have fairly similar specs. Many speaker kits only contain blueprints for the cabinet – you will have to buy, cut, and fasten the wood together yourself. I’m not some kind of hifi conass connur connerse snob so am just interested in building something with some solid bass and punch.
The HD260 is a small tower speaker using the Fountek ribbon tweeter and two Peerless HDS 832873 5-inch mid/range woofers This uses a Nomex paper cone, a very large ferrite magnet and neoprene rubber roll surround. If you are just looking to get excellent sounding speakers at much lower cost than what is available commercially, by all means, build someone else’s fully documented project. If you don’t do this, your circuit may not work due to putting the op amp in backwards. I converted some old car audio speakers to a pair of bookshelf speakers pluss bass bin.
Yes, I am trying to work with a particular price point; I’m not exactly rolling in money, and I would like to be able to assemble a speaker set for around $200 total (including wood for cabinets). There is no cutting or finishing (painting / staining) required to complete the speaker kit. The overall frequency response of the Signature Series HD260 and HD360 speakers is commendably flat to below 50Hz. From a money standpoint, not much more is saved in designing your own – most of the savings comes from building the cabinets yourself and assembling it yourself.
If you have Madisound build your crossover and don’t like it, you’re stuck with it. Build it yourself, and you don’t like it, you change a couple things a little bit. If you fall into the first category, a $30 pair of small cube speakers will do you just fine. Modular Design – headers connect the speaker and battery pack to the circuit board, so you can easily try different configurations or replace a broken part.
While impedance is important in this sort of setup, speaker sensitivity is what you’ll find limits volume. Its the same concept just not in color and not with pictures of the components:-) The R’s are resistors, the C’s are capacitors, U1 is the amp chip, etc. For the best bass performance, seal any gaps or air leaks in the box with hot glue or caulk then fill the box with a moderate density of Dacron pillow stuffing. Contact Nicole at Start Ranking Now, and begin planning your professional speaker promotion kit. Volume: I measured peaks 90dbs at 1 meter distance before distortion set in. This was with an 8 Ohm speaker of mid/high efficiency.
Though bass was limited by the speaker’s size, it was well-balanced, without the inaccurate, bloated sound you hear with cheap speakers purposely pumped up to overcompensate for their size. Placed against the same wall, they may even sound ‘boomy.’ You can use your receiver/amplifier’s equalization to increase or decrease bass frequencies as needed; this is often the best solution since you may want to move speakers to different locations if your rearrange the room. I’ve also used in the past in order to source cheaper parts (including a speaker). However, the primary one for this speaker system is to give the two speakers a place to rest and direct the sound waves.
BTW the RB kit is from Madisound, Parts Express has the ‘Recession Destroyer’ which is a design from a very respected XO designer… though keep in mind they are cheapie drivers. My room is basically a 13ft x 17ft rectangle, with the speaker locations on either side of the center of the 13ft wall (can’t change that as the missus has the office as she likes it!).
However, consider this for a modification: In a tightly sealed box the movement of the speaker will be severely restricted. Parts Express sells many DIY speaker and subwoofer kits, but they are not necessarily high-end. We won’t claim to be the ‘best,’ whatever that means, but we do provide an excellent speaker at a price that is proportional to the quality of the finished product.
However, if you have an ‘active’ amplifier, we need to know this before making your speakers so that we can make the necessary changes to the circuitry. If you’re planning on getting inventive quick and straying from the basic directions, please don’t yell at us if your Fab Speakers suck or don’t work. Heck we can build DIY speakers to match +$100K comercial speakers….that ratio is more like 10 to 1!!! It is also helpfull to glue a dowel (or similar) inside the speaker in between the two sides. The small horn speaker kit goes together much like ready-to-assemble furniture.
