BrazCherry.jpgOrion DIY speakers1522 viewsThese dipole speakers are available as a DIY project, a kit, or completed speakers. You can purchase the plans from Siegfried Linkwitz (www.linkwitzlab.com).
The speakers use two 10" Peerless subwoofers, an 8" SEAS midrange driver and two SEAS Excel tweeters per cabinet. The active crossover circuit board is also available from Linqwitz Lab. The documentation includes all that is needed to build these yourself. For those who want some of the assembly completed, the crossover is available fully assembled and tested. A kit, unique parts and brackets for completing the construction, and completed speakers are also available. The speakers are driven with 8 channels of amplification (60 watts per channel). One can parallel the woofers to get by on 6 channels. There is much information on the web about the quality of these speakers. Anyone seeking very high quality speakers at a DIY price for music reproduction or for home theater will not be disappointed.

reds.jpgDIY PVC Pipe Speakers with HiVi B3N driver1309 viewsThe speaker enclosures are made using various PVC pipe sections. The PVC pipe enclosure houses a 3-inch HiVi B3N fullrange driver. The enclosure is tuned through bass port at the end of the pipe stand. Binding posts are on the back. The frequency range is about 80 to 20,000Hz . There is a nice sound stage and pretty good low end response considering the small size of the driver and enclosure. I would love to hear your comments about this HiVi B3N Full Range Speaker project.

Fostex-FE206E-Double-Bass-Reflex-Speaker-Enclosure.jpgFostex FE206E in Double Bass Reflex Speaker Enclosure1205 viewsThis is the simpler enclosure recommended by Fostex for their high sensitivity FE206E drivers. The large magnet and basket spokes of the driver have been covered with bituminous damping. The upper chamber has sound deadening vinyl across the back and the rest of the upper chamber has double layers of thick Dacron lining it. The boxes are fastened using dowels, glue and wood screws. A Speaker Zobel / Impedance Equalization Circuit is used across the driver terminals. The sound soundstage is pin-point sharp and with good depth. Bass is sufficient without being heavy. For under $AU500 these speakers represent very good value. With a sensitivity of 96 dB/W my 6 W Ultra-Linear Single-Ended valve amps can produce a high sound level.

PeerlessSeas2way~0.jpgPeerless and Seas 2-way Towers in Zebrawood1136 viewsThe fun part about building these speakers was the crossover design with a Zobel and Baffle Step Compensation (BSC). I wanted to try a larger driver than a 6.5 inches. I am really pleased with the sound and image. Unbelievable sound for the cost. The crossover uses open air inductors and Solen capacitors. The Veneer is Zebrawood adhesive backed. I was able to match the grain on both sides and the fronts. One coat stain and finish followed by paste wax. The speakers are drying in the garage awaiting the living room. Next is a pair of open baffle 3 way with active cross using DIY chip amps.

Tang-Band-D4-1-DIY-Back-Horn-Speaker-Kit.jpgTang Band D4-1 DIY Back Horn Speaker Kit858 viewsThe fun and simple Tang Band D4-1 DIY Back Horn Speaker Kit. This little speaker kit comes complete with all the parts and tools required (minus a soldering iron). There is no cutting or finishing required (no saw dust or fumes!). The kit is very simple to build as it goes together just like ready-to-assemble furniture.
For a full review of this speaker kit, see: Tang Band D4-1 DIY Back Horn Speaker Kit.

Seas-CA26RE4X-sealed-subwoofer.jpgSeas CA26RE4X 10-inch Sealed Subwoofer585 viewsSeas CA26RE4X 10" subwoofer in a sealed 1.27 cubic ft cabinet. I used 3/4" maple plywood with mitered, biscuit-joined seams. The driver port was cut, then the lip routed, then scabs glued in with Gorilla Glue, then drilled and fitted with threaded caps. The rear panel was sealed with strips cut from a bicycle innertube as gasket material. Originally wanted to stain black black, but I think the natural wood grain really looks good.

Diaphony8~0.jpg"Diaphony's" An open baffle design508 views"Diaphonys". A Dipole with a 10" separation between cabinets (21”w *18”h*6”upper cab) to direct reflected waves to the listener. Low distortion driver choices with a SB Acoustics 29RDC-0004 for highs, Usher Audio 8945A for mids, and an Eminence Alpha15A for lows (lower cab same as the upper but extened to 12” depth). These drivers work together nicely together with a 2nd order LR with the low end of the Usher rolling off naturally. Upper cab with a 8" cardboard tube to direct waves from the Usher from the back of the 6" wide speaker box depth to the reflected surface with minimal re-reflection to the back of the driver. I used a 6" diameter plywood rounded baffle ends to reduce diffraction losses and to improve off axis response. Claity SA Caps where important, Solen Fast Caps else where. Goertz inductors with Madisound Sledgehammer for the Alpha 15A. Balic Birch construction with Walnut veneer. The sound? I knew immediately when the SB and Usher were on just a 22" wide by 60" tall board I had made good choices. The cleanest mid I have ever heard. I'm sure there are better ones, but not by much. Voices that were unintelligible on other systems of recordings I know well became understandable - embarrassingly so. A wood block sounds like a real live wood block. I primarily used various tracks off Tania Libertad’s album “Costa Negra and Pacifika’s “Asuncion” for listening tests and crossover tweaking – two extremely well tracked and mastered albums to say nothing of the voices and talent. While listening to track 12 of Libertad’s album “Yo Venco A Ofrecer Mi Corazon”, in my listening area, it becomes to difficult point to speaker placement without visual cues. The Diaphony’s are large, they do need to be about 4 feet away from a back and side wall seem to be the only distracters. Many compliments at the recent Northern California DIY Audio meet outside of Sacrameno, CA.
