    I'm replacing speakers in my old Fender Bassman Ten combo. It's a 410 50watt combo. Does each speaker need to be able to handle 50 watts, safely? Or can I get 4 20 watt speakers?

    When hard clipped (heavily overdriven) and amp can put out upwards of twice its clean rated power. As such, I'd want 25W or better speakers to be safe.

    i would also go double the "wattage" in case you smash it with fuzz.

    Listen to what they say wwhen they tell you at least double the RMS. Minimum.

    For the money 4 x 10 Tone Tubby 40/40 ceramic would be a good/great match and 160 Watts. Some mix the Tone Tubby Red and Tone Tubby 40/40 1 to 1. But the TT Red is more expensive.

    If I had the money I would put 4 x 10 Fane AXA10 Alnicos. 100 watts each and 100db.

    My favorite CP 10in speaker. By Far. They are as loud and powerful as most 12's.

    Also dot ever let anyone tell you that you have to much speaker capacity. Especially if youre wanting no speaker distortion.

    An original Hiwatt DR103 ( Dave Gilmore ) came with 8 x 12 80-100 Watt RMS Fane Cresendos with Pulsonic Cones for a 100 watt amp. Thats 620-800 Watts worth of speakers for a 100 watt amp.

    In realit I would verge to bet that More people use much more speaker than they have amp rms.

    Pete Townsend uses 3 x 10 JBL E110's and 2 x 12 JBL E120's for a 60 watt amp. That's 525 watts worth of speakers for a 60 watt amp.

    SRV used 4 x 10 EV 10M. That's 400 watts worth of speakers in an open back Super Reverb. In a closed back the EV's are good for 800-1200 watts rms. He also used JBL E110s but they aren't as powerful as the EV 10M's. But are still 300 Watts for a Modded Super Rvb. 85 watts.

    But you've got a nice amp Id put nice speakers in it.

    Yeah the wattage multiplys with the number of speakers so four 25 watters is 100 watts.

    On the Bassman Ten watch the impdance the amp (stock) wants 8 ohms. Some used four 32 ohm speakers wired to 8 ohms total and some used four 8 ohm speaker wired for 8 ohms.

    If yours has the 32s and you put 8s in without rewiring you get 2 ohms. After awhile you'll be replacing the output transformer.

    If your running it wide open then yeah you want plenty of power handling. But if your like most of us these days and never get anywhere near that loud four 25 watters will do the trick. I run Weber Ceramic Sig Ss in a Super Reverb for instance.

    20-25 watt speakers will be fine since you're running four. How loud do you usually play and do you use a lot of gain pedals?

    I don't play insanely loud. I use a couple of tubescreamers, max. But now I'm wondering if the 30 watt Reaper I put in my Peavey Classic 30 is under powered :(

    edit: Just looked. It's the 50 watt Reaper. Should be ok, right?
