Evan is correct. I have tried many different speakers, most speakers designed for high power are not very efficient and while they will handle more watts, the SPL/1w is low. The "Collins" replacement speaker from the link is rated at only 7W. On the surface that sounds good, maybe means "more efficient", maybe not. One concern is the "whizzer" cone. The original Collins speakers did not have one. My hope is that the whizzer cone won't be very effective since I don't want high frequencies above 4-6kc, they just provide more noise and QRM.
I ordered one to see how it will perform. We'll see.

If one were to select an alternate speaker for mounting inside the MS-4 cabinet, it won't necessarily have better fidelity and less distortion. Why? Some of the speakers I've tried have had maximum power rating of 20-50 watts. When used with a TR-7, I found that I had to run the audio gain quite high, in some instances at the 3 o'clock position, since the speakers were not necessarily efficient. As one approaches the maximum output of an audio amp, sometimes the distortion level becomes annoying. Your results might vary. Enjoy those Drakes. 73, Evan, K9SQG -----Original Message----- From: Charles Ring <[email protected]> To: Bob Loving <[email protected]> Cc: drakelist <[email protected]> Sent: Tue, Apr 16, 2013 1:35 pm Subject: Re: [Drakelist] MS-4 Speaker Parts Express has or had another better-than-original speaker that fits the MS-4 cabinet.
