Fostex 6301

Hey all,

I bought a pair of Fostex 6301s after hearing they're a great 'grotbox' and, after only a couple of short tests I guess I am finding they 'holding a magnifying glass up to my mid-range' but I'm also hearing more presence and hi than anything else…

They have a painfully pokey 5-7k. I actually have to have them quite a bit quieter than my full-range monitors (I've got Genelec 8040s) in order to use them without braining my poor lugs.

They're also pretty distorted (there's no such thing a sine tone on these) and the stereo image seems extremely exaggerated. I actually thought one side was somehow inverted at first.

It might just be a case of getting used to them but I'm just here to ask… is this normal or have I bought a ruined pair?

Thanks!

never used them, but if you bought something described as a "grot box", you should not be 'worried' if they sound grotty.

Such things are used for 'checking' your mix. Maybe yours are 'broken', but maybe like you said, you are just paying too much attention to them because they are new.

I have a pair of Auratones - often called "Horrortones" for that similar kind of sound. They are very useful for checking certain things. But once I have checked, I go back to my real monitors. On average, I have them "on" for a grand total of about 2 minutes per hour of mixing.

Nothing "grotty" about those if they're in good shape. They have no low end to speak of -- how could they -- but they've got good fullrange drivers and decent amps.

They play loud because they're super-efficient, and they're super-efficient because they don't have crossovers. If they're breaking up, there's something wrong. Hard to say what.

And if the stereo image seems "extremely exaggerated," you might be running them out of phase.

Thanks for the note, guys.

Any comment on the peak at 6/7k?

Ah yeah, this is what I meant by "inverted" but when I check in mono it seems like they're fine.

Only other thing I can add is that if they're the original 6301's (no letter on the end), they're around 30 years old. No telling what could have happened to them in that amount of time.

I realize I am too late posting this, but maybe someone else will have the same issue with these monitors some time in the future ...

I bought two used pairs of Fostex 6301B on auction platforms within the last two years and both were very distorted in the low end, just like the OP describes. They were both "made in Japan", so probably around 20 years old. When I was testing the first pair I was absolutely sure they were broken and sent them back. But when the second pair had the same issue, I wasn't entirely sure anymore. But then I tested them against a pair at a friend's place and his speakers were clean in the low end. So I sent the second pair back to the seller too.

To make a long story short: I believe that the old Fostex 6301 are pretty prone to having their speakers blown, which results in low frequency distortion. Maybe it's a kind of damage that comes with age or maybe the previous owners just cranked them up too loud.

Here I go reviving this old thread again

I have a single one at home that exhibits distortion and very little low end. However I know these from my studio days, and recently bought a pair for my work venue. They are great, playing (as has been mentioned above) loud and clean if they're in good shape. And they go down to at least 100Hz

The reason I'm here is to ask if anyone's found replacement drivers other than the $50 ones at Full Compass? I love FC, but I paid less than that for my little 6301B.

Cheers
