Any suggestions on a a low cost, efficient bookshelf speaker to match the Sharp SD-EX111? The Usher 520's are now ~$400/pr. I would like to do something below $200/pair w/ >89dB @1W, 1M.
Anyone heard the new 4.5" driver from DIY Cable? I am thinking about my first DIY speaker. With a single driver there isn't too much I can screw up here. They are a bit pricey at $69.50 per driver and do not appear very efficient. I am thinking of going with the 16 ohm version.
Here is some information on the WR125 4.5" drivers:
The WR125S and WR125ST are the first small drivers made utilizing the Adire Audio XBL^2 motor technology. This driver has unheard of performance in a small 4.5" midwoofer. The combination of wide bandwidth, flat BL curve, EXCEEDINGLY low distortion and massive excursion make the WR125S destined to become an instant classic.
The clarity of the midrange is stunning and has a direct relationship to the advanced motor technology used. In addition, the well behaved roll-off outside of it's primary bandwidth makes for a driver easy to design with and applicable for use with low order crossover networks.
We intend to use this driver with a number of upcoming speaker designs among them a small 2-way monitor, 3-way monitor, MTM monitor & with a small center channel speaker kit. This is just the first of many exciting products to come utilizing the advanced XBL^2 motor technology.
Price is based upon single unit. Add two units to the shopping cart for a stereo pair. The WR125S is the 8 ohm unit and it has a round frame. The WR125ST (shown in pictures) is the 16 ohm driver. The WR125ST has truncated frame for easy stacking of drivers for line arrays and MTM configurations. Both are priced the same and you must choose which version you want in the options below.
