Another project underway, whew thats 3 in one month! Addictive stuff this DIY business and the simple fact is that the more you do the more you learn. Anybody can do it. Well after being left in limbo mid build on my XXX subwoofer project, I decided to keep my spare time filled with some thing I've wanted to do for a long time, yes thats right, build a full range speaker or more specifically a 2 way floor standing design. Like most people I wanted to build something special, something that did things a little differently to the run of the mill DIY stuff and so the 'Vista' was born. I always name my projects since it tends to give them a personality as they develop - call me mad but it just makes sense to me. I knew what cabinet shape I wanted and the fact that I wanted a 2-way Transmission Line design featuring a HF unit alongside a mid/bass unit. But driver selection was everything but simple with so many designs available. To cut a long story short I choose 2 drive units from the same manufacturer and both with the same nominal impedance or Z, this was done in the hope that it may bring better integration between the two units when designing the crossover. Heres the two I eventually went for: The MHT-12 from Visaton is a Ribbon Treble unit and clearly fitted my design ideology of 'special'. It was mainly influenced by a demo of a design featuring the Raven R-1 Ribbon Tweeter and it was simple in another league to anything I have *ever* heard. Beautiful imaging, masses of 'air' and 'space' to the whole sound, very involving - even at low levels and revealing. The MHT is very similar to the Raven and has plenty of acclaim in real hi-end audiophile circles. Not cheap at £130 each but is quality ever? Heres the ideal partner to the Visaton Ribbon: The £120(each) TI-100 Mid/Bass unit, again from Visaton. Its only 10cm or 4" in diameter so this clearly isn't going to shake any houses down but then thats were the XXX comes in. With some careful cabinet design and the help of Transmission Line loading, something special - there's that word again , can be achieved. Well onto the pictures of the cabinet, which features gently contoured sides, I let the pictures speak for themselves and I'll post more as construction progresses.
