    Best 15 inch JBL Subwoofer?

    I'm currently using a pair of 2235 woofers as subs, each in their own ported 5 cu ft box. Are any of the newer JBL 15 inch woofers considered better as subs? Which ones? Thanks.

    SUB1500?

    IMHO, it is hard to beat the 2235H! I have heard good things about the SUB1500 however. There is a nice looking pair on ebay currently.
    Past practice indicates future behavior.

    Thanks for the info. I remember these woofers from when Parts Express was selling out some old stock. Do you know where I can get the Thiel-Small parameters for these? Also, do you have any idea how these compare to the JBL W1500H?

    I tested a 2205 reconed as 2235 and W15GTI in identical chambers of the same cabinet and the W15GTI was better below 40 Hz and blew the 2235 away below 30 Hz. It was actually more linear across the frequency band to 1KHz too. But they need lots of power. I push about 800 WRMS into it.

    I would stick with what you have. The newer 15's are rare as hens teeth. You doing these for music HT or both?? If you want to bring the house down you might want to look at an 18" 2242 or 2245's. Gonna need some big boxes though.

    These will be for music and HT. My room isn't that big, so 18 inch woofers are going to be overkill. I've got a thing about stereo subs for some reason. I was just trying to find out if there would be anything better to hand off to my 1401Nd mid bass drivers.

    Finding and acquiring the rare drivers are part of the fun of this hobby for me.

    How low will you be running your 1401Nd drivers?

    The 2235H is a nice woofer, for most music it plays about as low as most people would want, however for HT duty, it's limited Xmax will cause it to run out of steam on many soundtracks.

    If your crossover is at 80Hz or below, I would strongly suggest the JBL Sub1500 or the newer W1500H. These can be used in small sealed or vented cabinets and will produce amazingly good deep bass for music or movies. I would also recommend that you give them a bit of electrical encouragement. The most bang for the buck in that department comes from using the Velodyne SMS-1. By bang for the buck, I mean SOTA performance at an affordable price. I'd recommend the Velodyne with any sub... at least any sub that is seriously robust. A 2235H used as a sub can easily be overdriven and destroyed.

    I'm using an 80 Hz crossover at 48 db/octave. I have the lows cut below 15 Hz at 12 db/octave. I use a BSS Omnidrive 366T for all of my crossovers, so I can (and do) use some judicious response tailoring and level matching. Power is from a Bryston 4BST (250 w/ch) amp. Would I gain anything with the SMS-!?
