    Can anyone share their single driver designs?

    Curious to see pics and your thoughts.

        Not DIY, but I recently heard these: http://www.omegaloudspeakers.com/products/super8series

        I was very impressed. To me, they dispelled many of the myths associated with single drivers. They had bass, imaged well, did not beam, and had a surprisingly good top end.

          Yeah, but look at those ridiculous prices!
          A DIYer could do the same or better for way, WAY less.

            holy cow!

            They're.. so small!! I thought they were much bigger from the pictures, i never checked the dimensions. O_O

              I'm currently in the final painting steps on a pair of small floor-standers using the CSS FR125 "full-range" drivers I won as a door prize at InDIYana last month. I'll post photos and other info here when I get them done. The cabinet is an ML-TL with a modeled F3 of 45 Hz.

                I agree, the prices are a little much.

                    Here is an article with pictures at the DIY Audio site involving the Fostex 120 5 inch driver in a Parts Express .38 cu. ft. cabinet with a port and Zobel and BSC.
                    You could probably match up various full range drivers with the various size cabinets Parts Express offers . I'm thinking about doing it myself

                      I was just looking at those drivers. I will be curious to see how your project turns out. Please post when finished.

                      Thanks

                        I built a full range speaker using the Mark Audio CHR70 and I love them. They're inexpensive and don't need any filters.

                        The design is a dual-chamber reflex. F3~45Hz. The total internal volume (both chambers) is 8.1L. The external dimensions are 21.5"x5"x8.5" with half inch wood.

                          My one and only single driver design is called the "Bandit" and is on my site. The version that I built is a DCR (dual chamber reflex) cabinet design and it uses the Tang Band 4" Bamboo driver. I used a filter for baffle step compensation and to smooth out the top end response. They sound pretty decent for what they are and the main complaint is that the off axis performance is somewhat poor at the top end due to the size of the driver (see the interactive off axis frequency response charts on my site for details).
                          This problem with exist with any single driver design and the transition is based on the driver size (a larger driver rolls off sooner off axis).

                          I built three of them and they are currently being used in a home theater system which was originally a stereo setup using two Calypso bookshelf speakers (also on my site). The Bandits were added and used as center/surround speakers and they do quite good in that configuration. There is also a 1 cubic foot sealed sub using the Dayton RSS265HF driver with the 240W plate amp with 6 dB bass boost at 30 Hz. This combination works well to make a very capable but not obtrusive living room surround setup.

                          The Bandit design is below...

                            Zaph has a design using the Hi-Vi B3S driver as a single speaker design. It looks like a good speaker as long as you keep in mind the limits of a small single driver design, little bass output, limited to low volume especially without a subwoofer, high frequency off axis rolloff.

                            http://www.zaphaudio.com/audio-speaker18.html

                            HiVi B3S, Zaph Comments: "Pretty good midrange performance, especially considering the price. Very smooth response, with a minor 8kHz breakup. Below 130hz, bass turns to thick mud. *Do Not* run this speaker without some sort of subwoofer crossover, preferably active at 150hz LR4. You might be able to cross at 100hz LR4 if you can trade a little distortion and output for subwoofer localization. This driver can run without a tweeter, but will sound better with a notch filter and a small amount of baffle step compensation. Cheap stamped frame, no voice coil venting. Widely available at many vendors. Tested June 2006."


                            Jordan JX92S, Zaph Comments: "Very wide and smooth frequency response. This is a full range driver that actually sounds good run full range with a simple baffle step compensation circuit. When you get 10 degrees off axis however, the high end disappears from beaming. Decent overall performance, but a poor value. A pair of better sounding 2-way systems could be built for the cost of a single JX92S. If you're convinced there's some sort of magic to a full range driver, this is one of the best, far surpassing most others I've come across. Tested March 2008."


                            Mark Audio Alpair 6, Zaph Comments: "It's good wide range driver with a few flaws. There are no serious issues in the harmonic distortion and the response is extended. Aside from the metal cone breakup in the top octave, there is a major resonance at 1900 and a minor at 800. Not too bad, but generally outperformed by several other wide range drivers, most for less money. The Alpair's response curve is pretty far off from the manufacturers, which may indicate a consistency issue. Tested March 2009."


                            Tangband W4-1337SA, Zaph Comments: "This is a very wide bandwith driver that could work as a small woofer, a dedicated midrange or even a full range driver provided a filter is used to tame the top end. This driver's breakup node above 10kHz does not propagate as harmonic distortion lower in frequency, meaning you can cross it over as high as you want. Harmonic distortion is merely average, but the smoothness of the response curve is class leading - a fair trade to many. This is a titanium cone, but it exhibits very "non-metal" behaviour due to the thin, light cone with exponential profile. Generally good value and consistency. It has a underhung voice coil that is vented under the spider, a cast frame and great build quality all around. Tested June 2007."


                            I have a pair of Fostex FE126E 4.5" drivers that are efficient, but can sound harsh at a loud volume. They also have very little x-max, so they really need some help in the bass. I consider these a midrange driver with a wide bandwidth.

                              Thanks for all of your comments.

                              I am toying with this for HT.

                              I was thinking of a 2-way design using a "full range" driver with a side firing woofer in a slim design tower. Crossing over around 150-200hz.

                              Any thoughts, someone must of done something like this before...Right?

                              Staying kind of on the same subject... what is the highest xover point that you would recommend for a side firing woofer?
