A Guide to HTguide.com Completed Speaker Designs.
This is a guide intended to help people locate and choose between DIY Speaker Designs completed here at HTGuide's Mission Possible DIY Forum or by friends. These are designs that you can have confidence in. These designs are fully documented and ready for building. These designs were based on in-box measurements and have been constructed. Additionally, most of the designs here (in one form or another) have been extremely well received at various DIY events. These designs are well supported by the good folks at HTguide. If you have any questions about the designs, please, pull up a chair and start a thread.
This is not an index of the entire web as there are just too many to keep track of. There is nothing wrong with designs elsewhere, and them not appearing here is not a reflection upon them. I just don't have the time.

Special thanks goes out to our fearless forum leaders: ThomasW and Jon Marsh. Additional thanks to all of the designers that have given their designs away freely to the community.
Notes:
1) Price listed is typically the cost of the drivers and recommended crossover components at the time of original construction. Prices typically do NOT include required items, such as: the enclosures, wood, binding posts, flared ports, poly fill,etc.
2) Prices listed are for a PAIR of speakers.
3) Designer typically references the crossover designer.
This is intended to be a living document that will get updated as new designs are added. Last Updated: December 1, 2014!
Designs are organized by Type (2-way, 3-Way, Center, Open Baffle) and then Price.
Note: People frequently ask for designs intended to be placed inside entertainment centers, bookcases, or on shelves, or on walls. If you intended to place your speakers anywhere but away from room boundaries, please understand the effect this has and choose a design best suited to that location. Some designs here are designed to be near the wall. In-Wall designs can be adapted to inside entertainment centers.
Please see this thread for an understanding of what impact that makes. http://www.htguide.com/forum/showthread.php4?t=34016& (Graphs repeated for those that won't follow the link)

The Chameleon
Design: Stand-Mounted 2-Way Closed Box/Passive Radiator/Ported (Your choice)
Price: $268 - $466 (Various options)
Size: 17" H x 10" W x 12.5" D, Parts Express 0.75 cu. ft. box
Tweeter: SB Acoustics SB25STC-C000-4
Mid-Woofer: SB Acoustics SB17NRXC35-8
Designer: David Ralph
Other Design Notes: Options are shown for closed box, passive radiator or port. Multiple crossover implementations are also shown. The box highpass should work reasonably well with a separate subwoofer with the common highpass of 85Hz. System sensitivity is set to get a bit more low end extension.
Comments: The strong point of this design is the midrange. Vocals are especially clear and natural. Sibilance is not emphasized at all, yet the highs are extended. The limit is the low end response, but that must be expected from a 6.5" driver. If a subwoofer is used, consider running the system full range rather than from the subwoofer crossover highpass. The system impedance for most crossovers shown goes down to 4 ohms, but an amp rated 100W into 8-ohms (or better) should work for most music systems.

Comments: This project developed to satisfy my curiosity on a number of issues. Having done a number of tests on the Dayton RS series, as well as others, I was curious to see how well my measurements could be used to help guide crossover design. I was also curious to see if I could get almost as good bass extension with an 8" driver, in the same size sealed box that would typically be used for a ported 7" driver. I also wanted to try out the Cauer/elliptic filters to see how easy they are to implement, and to look at the off axis behavior of this type of crossover compared with a more typical LR4 crossover.

Wavecor Ardent
Price: About $2900 for drivers, crossovers as built vary between about $1200 and $1500; cabinet materials including LBL panels for front panel about $400-500 in materials.
Size:* Basic dimensions are 42-43" tall (depending on base design, whether tall base is used with crossover installed in bottom), 11" wide, and about 16" deep at any one point, remembering that the total front to back depth from floor to top is greater because of the angle.*
Tweeter: ScanSpeak D3004/6640-00 Beryllium dome tweeter - other SS models (6620, 6600) were evaluated and discarded. The 6640 has low resonance and low distortion amplification, and a minimal breakup, matching the Accuton midrange driver in it's overall low coloration and very low high order distortion.
Midrange:* Accuton C90-9-079, matched pair. Core concept for this speaker was the use of this midrange driver- due to low resonance, low distortion, and extended response, no other type considered.
Woofer:* Wavecor SW223BD01 - 4 ohm, wired in series. A number of woofers were considered and tested in prototypes during the evolution of this design, including the Seas ER18RNX and the ScanSpeak Illuminator 18WU/8747T-00; and the 8" aluminum ScanSpeak Revlator; the desired low frequency performance required shifting to a sealed design and searching highly linear small form factor woofers, which like the Aurasound NS12, straddle the line between a subwoofer and woofer construction, offering a very stiff cone, exceptionally linear motor, and declining distortion up to 1 kHz; this supported creating a sealed alignment with a robust well damped bottom end similar to the much larger Isiris system, but of necessity at a lower sensitivity point (approximately 82 dB, similar to Magneplanars).
Designers/team:* Jon Marsh with DAR47 and Benthe8track
Other Design Notes:*Crossover is similar to the Isiris, being a three way implementation of a modified LR3 concept designed to work specifically with the normal driver offset delays of drivers mounted on a common front panel. Woofers are connected in series, to provide an easy to drive amplifier load. The net load impedance is very benign and quite flat, especially considering no external conjugate networks are used to reduce impedance in the crossover regions; this is an inherent characteristic of all realizations to date of this crossover type, which may improve driver damping and limits impedance swings for amplifiers to deal with, especially vacuum tube and non-feedback types like Ayre Acoustics or Theta.
Felt diffraction control is used in the grille panel, in conjunction with the crossover optimization to produce a wide vertical window with relatively small changes in response and minimizing diffraction effects to the degree possible. This measurement was not made with any attempt to optimize the low frequency positioning in the room (it was not in a normal listening position) and so response variations around 100Hz and below are due to non optimal setup and the long measurement window (200 msec).
Distortion was correlated from one of the frequency response sweeps, at a level of about 90 dB. All drivers exhibit good performance, but especially the midrange.
Related Designs:* Isiris three way using Aurasound woofers, Accuton C173-6-90 midrange, and Jantzen JDT-1024 diamond tweeter; NatalieP, Modula MT; all using the same modified LR3 crossover concept.
