DIY Oris horns

Extraordinary sensitivity (up to 114dB!), life-like dynamics, pinpoint imaging, great detail, great bass and very natural tonal attributes - all Oris DIY loudspeakers share these qualities, taking you closer to music than you’ve imagined possible.

Our customers appreciate the performance our systems provide, and build their own speakers for fun or to save money. As they discover, the combination of Oris front horns, suitable full range drive units and a compatible woofer system is a fantastic recipe for musical satisfaction.

Our customers experience shows that, with basic skills and tools, you can realistically build and finish one of our ORIS DIY loudspeaker systems. Any part of the process you can’t or don’t wish to undertake can easily be done with the help of others.

Check out our Showroom for examples of DIY-systems based on our products.

We supply horns, a wide range of drivers, upgrade kits and phase plugs (if required) to which builders add a woofer system to complete an Oris DIY system. Detailed designs and construction plans for our range of recommended bass enclosures and filters are available here.

Parts are supplied to varying levels of finish, as follows: 1) unfinished parts; 2) partly assembled units; 3) completely assembled units; and 4) painted parts/units.

System options:

All Oris DIY loudspeaker systems are related, giving you flexibility in assembling a system that suits your taste and circumstances (listening room, system, budget etc).

At its most basic, an Oris system requires a pair of either the 150 or most recent developed 250 horns, a suitable pair of drive units for the horns, potentially a pair of our phase plugs, and a bass system. The horns must be painted, as this has a significant effect on their performance.

For the full range drivers we highly recommend Lowther or AER drivers. However, users claim to have very good results using Fostex FE206En and certain Tangband drivers.

Our most recent Oris 250 horns offer a new range of options:

The Oris 250/8 is the horn which is smaller in diameter (55 cm) than the Oris 150 and has the least depth of all Oris horns available. This reduced depth give more freedom to the sound without any coloration. This horn is for use with 8" drive units.

The Oris 250/6 is in principle the same horn but then with a smaller throat. This horn works very well with the Fostex FE166En or the smaller Lowther 45/55/65 series drive units.

The Oris 250/2 is designed for using 2" compression drive units.

Drivers and amplifiers:

You will also require two amplifiers – one for driving the main horns, and the other for driving the bass system like the Hypex PSC2.400 plate amps having a neat built-in DSP Xover.

All ORIS systems built following our suggestions will give excellent micro and macro dynamics, transparency, stable and accurate imaging, detail, and deep and dynamic bass down to below 30 Hz.
