    Bob's M125 and my spiral bass horns

    Post by carpenter on Mon Sep 08, 2014 2:56 am

    Hi all,

    I'm new to the forum, but thought I'd take a moment to share my success with Bob's M-125 monoblock kit. I purchased a pair with Sovtek tubes and with a week of spare time, voila', I had an operational set of subwoofer amps to drive my monster, spiral bass horns.

    My initial impression was favorable, but I couldn't get over the roundness of the bass notes. I expect kick drums to have an edge and plenty of slam. It took a while for me to sort out the problem, I've even ordered the WZ68 rectifiers and 12BH7 tubes, hoping for improvement, but in the end I remembered that Bob's amp's don't invert phase as do most amplifiers. My system is tri-amped and the mid-bass amp inverts, after flipping the M-125's banana jacks over to reverse the phase, the slam came back--in spades! This is something to remember, Dynaco fans.

    Just for kicks, go to my website to see the spiral bass horns (and many other horns) I hope you enjoy the pics.

    I urge everyone to go to John's web site and check out the construction of these very unique spiral bass horns. I have never seen a BASS speaker like this before. Usually bass speakers are sub-woofers or some "big-mutha" 15+ inch dynamic speaker. Check out the photos near the bottom of John's spiral bass horn web page on the "fabrication" of his spiral bass horns.

    Bob, it's too bad we're not neighbors. I think you'd get a kick out of my system. Come to think of it, I'm selling a full blown system to someone in your neck of the woods. He lives in Manhattan. When I get it up and running, I'll have to have you over for an audition/listening session.

    Can you believe that my wife is OK with me building these things? She's a rare breed of woman!!  queen

    They are the best sounding bass horns I've ever heard. Most bass horn can hit a low note, but they distort. These horns are smooth as a Cadillac.
