WD25T - The Sequel - is our latest, upgraded, version of the original WD25T kit published in Hi-Fi World magazine in 2006. New, in the Sequel, is a revised cabinet construction utilising our ARCENA sandwich cabinet material specifically designed to reduce panel resonance and block sound transmission from the interior of the cabinet.

WD25T is a Floorstanding version of WD25A using a technically advanced double enclosure separated by an aperiodic vent to give precise, controlled and extended bass performance allied to the midrange clarity and treble detailing provided by this classic two-way design. If you want the control and lucidity of bass provided by Aperiodic damping, but with greater bass extension and power, then WD25T is the choice for you.

With 88dB sensitivity for 1 Watt input and an easy-to-drive 6 Ohm impedance, WD25T is the ideal choice for valve/tube amplifier owners and will also raise the performance level of any solid state amplifier.

LspCAD6 Lite Speaker Design Software

LspCAD6 Lite Speaker Design Software

£59.00 / €87.32

LspCAD6 Lite is PC based software that provides the ideal environment to design your own speakers. LspCAD v6 is used by Speaker Design professionals in major companies all over the world to design some of the specialist hi-fi market's most prestigious and popular speakers.

Here, for the first time, is a version of LspCAD dedicated to the home designer. LspCAD6 Lite incorporates all the box alignment, crossover calculations and 'optimise' functions of the Pro version - in fact everything you need to design the perfect speaker for your uses.

If you haven't tried it before, LspCAD is more, much more, than just a speaker measurement and box calculation program. Within LspCAD6 Lite you can start by designing your cabinet and trying out different drive units in it, all in a virtual lab! Then, when you have constructed the real thing, you can measure the output of your drivers, using the MLS function built into LspCAD6 Lite, and start on the crossover design.

LspCAD6 Lite allows you to construct both active and passive crossover configurations just by dragging and dropping components onto the page. In this way you can construct as simple, or as complex, a crossover as you like and see the results displayed on the output graphs in real time.

If you are unsure what the component values in a crossover should be, don't worry. LspCAD6 Lite includes an Optimiser function which can either adjust the crossover slopes to any desired target, or just automatically adjust your crossover values to achieve a flat response.

You can change the component values and characteristics easily just by typing in new values or by using your keyboard arrow keys to move the value up and down, all the time watching the effect on the output graphs.

This really is a boon when you are 'fine tuning' a crossover. For example you can listen to your crossover, change some of the components to make it sound 'better' then immediately adjust those components in LspCAD6 Lite to see what effect they have on the output graphs. Once you've measured your drive units there is no need to re-measure the speakers again - LspCAD shows you exactly what is happening automatically.

The output graphs show frequency response, impedance, crossover transfer function, phase, group delay, cone excursion and port air speed, in fact everything you need to know about how your speaker is going to behave as you finalise the design.

LspCAD6 Lite is available to download now. You can try it out as a fully functioning demo for 15 days before purchase.



Note: This software is suitable for PC users and is a Digital Download (no shipping required).
