C8R 8 Ohms : Not for metal

I purchased this speaker upgrade for my Peavey Blazer 158 (USA made) because I felt the stock speaker lacked clarity and sounded muddy, which wasn't ideal for my metal playing. While the upgrade was better than the stock speaker for clean sounds, my review will focus on its performance on the drive channel, which I use exclusively.

First impressions of the speaker were positive; it looked sturdy and durable. I installed it with hopes of improving my amp's sound and adding to the positive reviews from other users who claimed that the upgrade added more headroom, clarity, and volume.

I found that they were right - the speaker did indeed increase the volume, highs, and overall clarity of my sound. However, this also meant that I had to crank the amp up significantly more than before in order to get any kind of break up, rendering the term "practice amp" somewhat useless. At reasonable volume levels, the sound was terrible, lacking in usable mids and filled with booming bass and piercing highs that made my amp sound like a bad Boss HM-2. Adding an OD pedal to reduce gain and add EQ control didn't help the situation.

While it's true that amps generally don't sound great at low volumes, turning up the volume only added more low-end rumble and made the highs even more piercing. Note separation was nonexistent when playing fast, with all the notes muddied together and buzzing like a swarm of mosquitoes.

At first, I thought the speaker might be faulty, but after measuring its impedance, I realized it was functioning normally. I can only assume that it needs to be broken in and played at higher volumes for a longer period of time, but as of now, this aftermarket upgrade has downgraded the sound of my Peavey Blazer 158 rather than improving it. It's a shame, as the intent was to enhance my inexpensive gear, but the result was the opposite.
