    So I think I may have a bad driver. Tonight at practice my amp kept going into protect mode when I had this cab plugged in. It would make sound at low volume but at higher volume the speaker distorted and the amp would shut off. This is a TL606 cab I built with a Peavey BW driver. My other TL606 cab was working fine. I got the cab home and put a meter on it and it measures 19 ohms.. I am thinking the voice coil is on the way out. I have a line on a Eminence Legend CB158 here locally on CL it is rated at 300W not sure if that is enough. My BW was 350W and I seemed to break it. I am not real sure how much that really means though. I am also looking at the Eminence Kappa pro 15A and Eminence Kappa 15A. Anyone have recommendations on a replacement driver for this cab that hopefully won't blow.. Thanks!

    Which BW do you have, and what amp are you using?

    BW 1502 8 ohm and I was using a Carvin B1500.. I noticed the amp clip light come on and off when playing which sometimes happens then it went into protect mode.

    Yep, definitely enough amp to blow a 15". Don't know enough about the subject to help, but I'm sure someone will.

    Yeah last practice I used my Mesa 400+ and everything was grand.. Sounded good with two TL606's. I got lazy tonight and used the head that was already at the practice space (the B1500) The other TL606 has an older Eminence built Carvin PS15 in it. I have had that driver since 98 and it has always worked well and sounds good. I think it is rated at 600W. I was able to make it through practice with just using the one cab..

    Maybe a second PS15 would do what you want.

    Drop a 3015 in it.

    Running an Eminence 3015ho at more than 700 watts rms is going to end in tears too.
    Maybe not as quick and maybe the voice coil would survive for a while but in the end any single 15" musical instrument driver is at extreme risk of cone failure driven like that.

    The cab was designed by EV (electrovoice). I've been thinking of building one, but never seem to find the time. I have the "right" speaker
    for it: newly rebuilt/reconed EVM 15B pro, 400W, 8 ohms. AWESOME vintage speaker, but a bit on the heavy side (cast frame, and big magnet).

    The original plans are actually for EVM15L, not 15B. Many have used the 15B in those cabs over the years perfectly happily though.

    I've seen quite a few with the Eminence Kappalite 3015 loaded in them, FWIW.

    I have had this driven into my head over and over as I fiddle with cab design - speaker wattage is almost NEVER the limiting factor in bass cab design. X-max is the killer (at somewhere sub-100 Hz, usually) - model the driver and box in WinISD (or fdeck's web model) and see. BW's are not all that stunning on the X-max spec (Scorpions like I have, even less so.)

    That is a monster of an amp for a single 15 ...IMHO .... i have used 3015's in those TL-606's and it is a good sounding set-up ...YMMV

    I've had a TL606 since the mid 80's loaded with the original EVM15L....I think I might have re-coned it once. For several years it saw either a GK 800RB or Bryston 4B pushed hard 3-6 nights a week and I still use it regularly. If I had to load it with a new speaker today I'd use a 3015. It's available and it works well with this box....kind of a no brainer.

    The 400+ would be happy running into a direct short, the SS Carvin will protect itself from going up in smoke. If you measured 19 ohm DCR that driver is toast and maybe shorting in use till the voice coil finally burns out.

    Yeah, you are correct. Not much difference between the two, IMHO, other than the L is brighter sounding (a bit too much for my taste). Not sure they made the L in a "400W "pro" version either???? Both are a great choice for the cab.

    Well I went with a Delta Pro 15A I got a good deal on. I found several recommendations on the EV forums on line that this driver works well with the TL606. I could not afford the 3015, wish I could.. The EV 15L has an xmax of 3.3mm and the Delta Pro 15A has a xmax of 4.3mm the Carvin PS15C that I have used in one of these cabs for years has a Xmax of 1.8mm. I was also driving two TL606 cabs with the B1500 when this happened.. So now you all have me worried that I'll blow these speakers again with the B1500 or the Mesa 400+???

    And on another note would using a port cover help lessen cone excursion and hopefully help prevent over-excursion and breaking another driver?

    From EV:
    For Bass use the TL606 vent should be partially covered to lower the box tuning to 40hz (step-down mode). This discourages speaker bottoming at the low bass notes.
