Designs offer driver recommendations, crossover schematic and complete woodworking plans for custom cabinet self-build. Celestion, one of the worldʼs leading suppliers of professional loudspeakers and compression drivers for sound reinforcement applications, announces the availability of Celestion driver-specific cabinet designs for DIY builders.
Celestion has long been the go-to choice for upgrading the drivers in an existing system, and now DIYers can build their own full-range, high-quality, Celestion-driven P.A. cabinets by following the companyʼs CKT-TF1525e and CKT-TF1225 speaker designs, as well as the double-duty CKT-TF1020, which can serve as both a satellite speaker and a floor-wedge monitor.
These DIY designs each feature a Celestion bass/midrange driver, and an HF compression driver with accompanying horn, plus a recommended crossover. Complete plans (downloadable as PDF files) make it simple for musicians and audio pros with some experience in cabinet-making or woodworking to build the ported enclosures out of their material of choice: a5mm birch plywood or a8mm MDF is recommended. The plans also provide a detailed listing of crossover components as well as a suggested layout, and a guide to finding the assembled cabinetʼs balance point for adding a stand-mount socket.
Why build your own P.A. cabinet? The benefits include substantial savings and customization compared to store-bought systems. For permanent or semi- permanent installations, one can stain or cover the enclosures to match any décor. Passive P.A. speakers such as these can take advantage of perfectly capable power amps you may already own. And of course, with the premium quality, high efficiency, and clean output of Celestion drivers, your music will be heard loud and clear.
The CKT-TF1525e is based around the 15" bass/midrange driver of the same name; the CKT-TF1225 system likewise begins with the 12" TF-1225 driver. On the 15" system, the CDX-1747 polyimide diaphragm HF compression driver is loaded onto Celestionʼs H1-9040 horn, which provides 90 degrees (horizontal) by 40 degrees (vertical) dispersion for treble detail across a wide soundstage. The 12" system combines the best-selling CDX-1745 driver with the same horn.
The CKT-TFa020 floor monitor pairs the 10" Celestion TF-1020 bass/midrange driver with the CDX1-1445 compression driver, which is loaded onto the
H1-7050 horn. The 70x50 horn ensures good dispersion of treble frequencies in both the horizontal and vertical planes delivering superb HF performance regardless of whether the cabinet is placed upright or on its side as a floor monitor.
If you have always wanted to build your own speaker cabinet or have done so before and are looking for your next project, Celestionʼs new cabinet designs provide an advanced, superior starting point. Not only do they employ high quality Celestion loudspeaker drivers, but all the work of design and measurement has been done for you. All you need do is assemble and play.
