MCM 55-2960 with Pyle PDS442+Dayton H07E

This is my second test with the MCM 55-2960. This time round, I’m using a budget Pyle PDS442 compression driver coupled to a Dayton H07E. I decided on this combo because of the low cost. The PDS442 is only $22.88 and the H07E is $7.99, available from Parts-Express. Add to that $15.21 for the MCM 55-2960, we have a measly sum of $46.08. For this minuscule amount, It’s worth testing whether this setup is good enough for HiFi. If not, it can always be used for PA. 

As before, the drivers are in a bi-amped, active setup. I used an external 24dB/oct Linkwitz Riley electronic crossover to divide the frequencies between the woofer and the horn combo. Crossover frequency is set at 1,200Hz.

Conclusion

I am stunned by the performance of this speaker. I’ve never been able to get anything I’m proud of with cheap drivers but this speaker is different. Believe it or not, it is at HiFi level.

I will definitely work on a passive version. It’s worth the effort.
