MCM 55-2960 with Fountek FE85
This is an exploratory look at how well the MCM 55-2960 sounds like with a Fountek FE85. For those unfamiliar with the FE85, it is a 3″ full range driver. If these two integrate well, I can do away with the tweeter. This will reduce cost. One less driver with the associated crossover.
For convenience, I’m using the SuperMicro box but with the FE85 instead of the Tang Band W3-1364SA. I decided on the FE85 mainly due to the low price. It’s only $10.90 at Madisound. Together with the MCM 55-2960, which cost $15.21 at Newark, this is possibly the cheapest 8″ 2-way that I can come up with. Hopefully, the sound quality will not be compromised.
Readers would have noticed by now that there is a Peerless tweeter above the FE85. Presently, it is not connected. Only the FE85 and the 55-2960 are in use. The drivers are in a bi-amped, active setup, meaning an electronic crossover is used to divide the frequencies between the woofer and the full range. Crossover is Linkwitz Riley, 24dB/oct. Crossover frequency set at 1,200Hz.
