Last Thursday I got a twitchy index finger and ordered a pair of these drivers after looking at them for a long time. The other contender's were 18Sound's 21NLW9600 and the TC Sounds PA5100. I could not seem to locate the 18Sound and the pricing would've undoubtedly been much higher. I was thinking about trying the TC when I found an incredible price on the B&C. $579.95 plus $25.50 shipping each. $605.45 shipped. That's a little over $100 cheaper than anywhere else I'd seen them. Had to purchase a pair while the getting was good.http://www.bcspeakers.com/PDF/PRD/21SW152.pdf
Here if anyone is interested. They have some other B&C stuff for cheap as well.http://www.savinglots.com/lotprod.asp?item=21SW152
It's a ghetto looking operation but apparently they've been in business for a long time and have a good rep. I guess I'll find out.
The drivers are due to arrive tomorrow.
These will be used in a PA type manner usually in a fixed location for drum reinforcement, some bass guitar and music playback, but they may ocassionally be dragged out for duty at local concerts, so they can be big but have to be manageable by just 2 guys. 600L is the limit I decided on. I'm only looking for full response from 100-120hz or so down to 25-30hz at which point they'll be hpf'd. Maximum loudness and fidelity over that range is the order of the day. I've got a few preliminary ideas for the cabinets these will go in, but I'm undecided still. Part of me wants to go for a regular old ported build because it's simple, relatively small and I could run the cabs up quite a bit higher than 120hz if there was a need for it. The other part says to try a horn build, whether to try a TH or a FLH though? Each approach seems to have some advantages.
I'll post my current simulations below. All sims are in 4.0pi space (anechoic) I'll be using a bridged Crest 8002 on each drive which is rated at 4000w into 4ohm. The RE of the driver puts the minimum impedance of any of the cabs in the 3.5ohm range which should end up near 4ohm minimum in reality. 117v is just under 4Kw into the minimum impedance. The amp should be able to easily deliver more voltage into the higher impedances (rated at 130v peak per channel).
I'm looking for constructive criticism guys. Give me some input
Got something that looks better than the sims that I have? Post it up please.
