ikyaudio_sound_pipes_small_1.jpgDIY PVC Pipe Speakers with HiVi B3N driver and HiVi T20-8 tweeter 8781 viewsThe speaker enclosures are made using various PVC pipe sections. The PVC pipe enclosure houses a 3-inch HiVi B3N fullrange driver and a HiVi T20-8 textile dome tweeter. The enclosure is tuned through a rear firing bass port. There is a 2-way crossover inside the enclosure and the binding posts are on the back. The speaker sits on a wood platform with spikes. The frequency range is about 65 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 / T20-8 PVC Speaker project.

K_16LS_Tube_Amp_Kit_with_PL_Preamp_Kit.jpgK-16LS Tube Amp Kit with PL Tube Preamp8286 viewsAfter months of looking I finally decided on the S-5 Electronics K-16LS stereo tube amplifier kit together with its sister PL tube preamplifier kit. The Stereo Integrated Tube Amplifier produces up to 16W and utilizes 5670 triode and 6005 pentode tubes. The PL tube preamp kit uses a 5670 triode tube.
I ditched the supplied wood board for a larger board to accommodate the preamp. Using my IPod and a set of Celestion floorstanders (90dB) I sat back to listen. WOW - seriously loud. Bass is fantastic, treble is sharp. Mid range seems to be missing a bit but after trying different tracks I am putting this down to poor quality source MP3 via the IPod. There is a reasonable amount of hum when you take the volume up but nothing annoying.
Next step is to attempt the mods for the K-12 kits.
