6T9FE167E.JPG6T9 Tube Amp and Fostex FE167E in Ported Enclosure.7569 viewsIf you have never built a tube amp, but wanted to, this low power SE 6T9 Tube Amp is a good starting point. But it will need efficient loudspeakers to go with it. The 6T9 amp cct. brd. is from Spare Time Gizmo. All components required can be easily obtained and the amp is simple to build. The Fostex FE167E is a 94dB efficient full range driver and works well with the low power 6T9 amp. All you need now is a CD player and you have an excellent den system or small listening room set-up. Let your mates have their B&Os you have something unique, great sounding and you built it all yourself! See the DIY Fostex FE167E Bookshelf Speaker page for more information about the speakers.

DSC00006_-_Copy.JPGDual stacked dual driver SoundSplinter subwoofers7539 views5 cu ft subwoofers with the SoundSplinter 15" drivers and 4- AE 15" flat passive radiators in each cabinet. I have them stacked or co-located to act as a single subwoofer. These subs model out to 13 hz at 1000 watts. Each subwoofer has a 1450 watt pro amplifier with the Reckhorn B-1 bass management system to control all frequency duties.

Realistic-Minimus77-Speakers-Grills-On.jpgRealistic Minimus 77 Speakers with HiVi BN4 Midbass Drivers7533 viewsThese Tandy / Realistic / Radio Shack Minimus 77 (metal enclosures) speakers had already had one upgrade with better quality 4" drivers some months back. But after a chip amp delivered pure DC into the driver, thus melting the voice coil, repair was required. The drivers are Jaycar (Australian hobby shop) re-branded HiVi BN4 4" aluminum / magnesium convex diaphragm drivers (see other image). The overall sound is bright with little music much below 100Hz. But as PC speakers or compact bookshelf boxes they are satisfactory. The crossover (1st order) was also upgraded with the high pass capacitor upgraded to a polypropylene metal film type.

SV101502.JPG10" DIY Subwoofer - The 4th Dimension7480 viewsYou can spend thousands of dollars and hundreds of hours making improvements to your system which may only make the slightest bit or difference (or so you think) . I put in a sub-woofer system based around a inexpensive 10" convex driver, DIY sub-woofer processor and a DIY 200W amplifier. Suddenly my system has a whole extra dimension.

FE167E.JPGFostex FE167E Fullrange Driver in Bass Reflex Enclosure7427 viewsI required some efficient speakers to compliment a small valve (6T9) amplifier which produced only a few watts. Here are the finished speakers. The enclosure design is the Fostex FE167E Recommended Bass Reflex Enclosure (15L). 18mm MDF was used which was glued and nailed together. The back panel (internally) has a layer of heavy sound absorbing vinyl glued to it and all internal walls have a thick layer of Dacron tacked to them. First impressions of the sound is very clear with strong transient response and pin point sound stage.

DIY-Three-Way-Tower-HiVi-Loudspeakers.JPGDIY Three Way Tower HiVi Loudspeakers7421 viewsThese are David's version of the DIY 3-Way HiVi Tower Loudspeakers by Adam. Each of the three-way tower loudspeakers uses one HiVi F8 woofer, two HiVi F5 mid-woofers and a HiVi RT1C-A Planar Isodynamic Tweeter. The tower loudspeakers follow the plans for Adam's build with the exception that a HiVi Research RT1C-A is used in place of the HiVi SD1.1A.

DIY-Speakers-and-Subwoofer.jpgDIY Speakers and DIY Subwoofer 7365 viewsI just finished building some budget speakers and subwoofer. Very basic design but that is the look I was after. It is my first project so I kept the components cheap. It sounds quite good considering the cost. Certainly a lot better sound than the speakers I was considering which cost 5 times the amount. Also I had fun and learned a lot along the way.
To get a perfect gloss finish and without the need to bog and sand screw holes, I first screwed the 19mm MDF together and then laminated (glued) 3mm MDF over the top. Next I trimmed the edges of the 3mm MDF with a router fitted with a laminex trimmer. After a light sand the boxes were ready to finish with no chance of seeing any screw holes.
I also made a cabinet to match and used some perspex for the centre panel and sprayed it the same colour as the subwoofer.
I hope this has inspired any budding diy speaker newbies. Im hooked now, im already planning my next project with better components.

SV101780.JPGOpen Baffle Speakers - Rear7339 viewsThis shot shows the OBs before two layers of darcon were stapled to the rear leaving only the woofer rears exposed. The particle board is 18mm the woofers 10", mids 2" domes and titanium tweeters. The Xover is a 2nd order. I replaced the HF caps with metal film polypropylene varieties from electrolytics. Heavy metal brackets join the base board and baffle broad. The boxes recline slightly so the speakers will stand up without other assistance.
Listing is pleasant with voice bright and bass OK but not deep. The woofers are new and very stiff so bass response may follow many hours of playing. See other image.
