Comparing the sound of Marshall 40watt 401 combo (tube amp) to the Marshall 50watt AVT, I noticed because the AVT is enclosed, it has more depth to the bass than the 401 has. I was thinking of enclosing the speaker to gain depth in the bass. Has anyone else done this? What was the result. I know someone will warn about the air flow needed to keep the tube and amp cool. I would leave room for the air flow freely to the amp section but enclose the speaker. I might as well add this warning: Do not obstruct ventilation grille and always ensure free movement of air around the amplifier!

I don't think it is that easy to enclose the speaker and leave space for tubes. I think that a closed external 2x12 cab is a far better solution - it will increase the sound quality in general.

Ya, your probably right. It's more trouble than what it's worth.

Definitely mate, specially because 401 has 4 power tubes.

I think Ivan's giving you really good advice here. However, the 401 is a true tube amp and in the long run I think you'll find it superior in tone.

Using the amp with a extension cabinet will give you the tone your looking for. But combos are great for practicing so you could go back and forth between a cab or the internal speaker.
