    I am thinking about joining a doom band.
    1. I will probably tune down to “A.”
    2. Amps: I have a fender studio bass (200 watts tube) and an ampeg v4 (100 watts tube) I will use.
    3. I have 3 of those diagonal fender 2x15’s from the 70’s for cabs.
    4. The cabs are loaded with vintage jbl d140’s and e140’s.
    Given my rig, am I in danger of blowing these speakers? Should I be using my fdeck hpf?

    Yes. Use the HPF set to about 45-50Hz.

    The D-140's are very low mechanical power handling, the E's are somewhat better but none of those are like modern speakers.

    Cool. So I’m hearing you say that with the fdeck I should be all right?

    Agreed, you'd likely be better off with something newer from Eminence. The JBL-E140's were the "last of the line" for JBL they had to revert to Ceramic Based Magnets vs Alnico because Zaire and Cambodia were

    very dangerous places to extract Cobalt from, during the 1980's. They were designed to handle 200 Watts. The JBL D-140's are alnico magnets. Just my take. You'd definitely want to use the FDeck. If there are two in each cabinet

    the speakers are likely to be 16 Ohms each.

    Using an expensive, nice sounding speaker for doom doesn’t make a lot of sense to me. You don’t know how healthy your old speakers are, they may not be up to spec. Why risk blowing them out.

    I’d choose an affordable modern speaker that can handle more than enough power. Let the pedals and amp generate the doom, not the speakers.
  7. even with HPF I think. No shame in running the HPF at 60hz.

    If it all gets harder to hear it's probably heating up coils and time to stop.

    Use modern speakers in well designed cabs for low tunings. Those old drivers are nice sounding for standard tuning, the enclosures let them down even then.

    PLEASE don't use those old Fender cabs for low tuned doom music! I would love to have one of those. They are not built for the music you're going to play.

    I don't wait 30 minutes after eating, to go swimming.
    Sure hope they come out with a new one!

    Poor cabinet design for the application.

    Your intended use spells doom for those JBL drivers. Better to use a more appropriate driver for the application.

    Poor cabinet design for any application. Those old fender cabs are terrible imo. Sunn probably made the best cabs in that era. But I wouldn't necessarily ovetpay just to have vintage.

    The easy answer is just get an Ampeg 8x10 or if you dig 15s, look at Mesa 2x15s. Personally I use a GK neo cab for the dooms (4x12) You could go any of the modern efficient cabs like barefaced or berg too.

    IMO you want good spl, low end response, and coverage for those old tube heads (which are perfect for this type of thing). The fenders have none of the above.

    To me doom bass tone is all amp and fuzz pedal, and not speaker cone overdrive. Ymmv

    Right on team. Thanks for the replies. So I’m, hearing “don’t do it.” Maybe, maybe, it’d be OK, but it’s better to be safe than sorry. I hear you—thanks.

    I was going to run the V4 with one cab that had two d140s. That would be for dirt. Then run the other two cabs (each with two e140s (8 ohms a piece 4 ohms total)) with the studio bass (the tap is 8 ohms but it’s good down to 4). This would be for clean. But I’ll get some different cabs. I’m keeping these though for other gigs.

    I know the vintage Fender cabs don’t get much love but I found I really like these diagonal cabs. Yes there is some low end rolloff but for the honky tonk, blues, soul, and gospel I’ve been playing for the last 15 years they’ve been perfect. I also understand their smaller size makes them a little inefficient but with the JBL‘s in there and the fact that I can run up to 6-15’s at a time I get more than enough displacement and volume for what I usually do.

    Spread the Gospel of DoomTM! Bwahaha! I bet—and hope—you'll have a lot of fun in this new direction.

    Please specify your genre of doom.

    If you’re playing old school Sabbath-worship I think you’d be hard pressed to find a better set of speakers/cabs to suit your needs.

    It you’re playing melodic Scandinavian funeral doom, yeah you might want to follow the advice in this thread and get some more modern cabs or speakers.

    If you’re playing immense single note drone, the answer will lie somewhere in the middle.

    I would consider the d140s more of a “full range” type woofer. They have great definition and clarity but they’re not going to like the tuned down low frequencies and heavy eq coupled with what will likely be substantial volume. Don’t do it.
  18. Weird. All the E140 I have come across have been 8 ohm. 1x15 PA and bass cabs, and 4 ohm 2x15 bass cabs.

    I'd go for the ubiquitous Ampeg fridge. The head should be fine.

    I think the drivers are fine. D140s and E140s are great and in a good cab like a Sunn 2x15, they rip.

    You might want to give her a go with your current rig. If you are running the 100 watter just for top end and the 200w for rumble/girth, the fender cab should be more than fine for highs. Hell, since you would be running 6 15s it might make enough air move! As long as the low end doesn't lose the plot. That might be where things go sideways. In that case, what about a fender neo bassman cab or 2? Fits the vintagey look, matches the heads, and sounds big!
