So some of you may know from my outdoor speaker tap thread that we are doing a fairly nice sized outdoor speaker system. Its a residential house but due to distances/amount of speakers we are doing 70v.

The system is controlled by a DBX Zonepro 640, (6inx4out) with crown amps. Today when i was sitting down with the pool designer, customer, landscape architect and the pool designer brought up sub woofers, and the customer got all excited and asked if we could do this for the covered deck.

I dont want to use up a zone for a separate 70v amp for just the sub woofer. I have done 70v work before but never with a sub woofer.Would you recommend i do a DBX 223 crossover or just place the subs on the line and use the built in crossover's?

BTW: for those that used them what's your take on the JBL 19CST's 8in sub woofers? this is for a covered deck, so its just to give the extra "kick"

TIA!

The 19CST is decent. There is not a built in crossover though so keep that in mind. The 223 would work well although if I were you I would just go to the ZonePro 1260. The EQ is so much more feature rich, plus you get a built in D/A, ethernet and some other goodies.

I would also recommend bumping up to the next size DSP and powering the subwoofer separately. With our projects in the past putting the sub on the same line as the other drivers made it harder to tune. Along with that the client always wanted more thump out of the sub before his ears started to hurt from cranking the volume up.

If your in a bind for money another thing to look at would be to bump up the existing drivers to any 8" style 2-way and increasing the quantity up one or two (tighter dispersion pattern). Subs are nice outside but if you have the room I think it blends better to have bigger drivers and eliminate the subwoofer.

Of course, if he listens to a lot of music that wants a sub...he needs a sub. I've used Tannoy and Sountube (in-ceiiling) in the past that have worked well. No experience with the JBL unit.

I can't comment on the model numbers as I was just following directions, but we put a ZonePro in when we remodeled Ernie's (no lie!), the clubhouse at PGA West in La Quinta.

The system has, above the main bar, four 8" speakers and two 8" subwoofers run off their own amp. Various other speakers -- a dozen or so -- fill out the rest of the main floor area.

Yup, you can use subs. I suggest you have a separate amp for them.

+1 on dedicated sub amp.

Yup, when we had originally met when we got to the music part the kids started acting up so we didnt really get into it. Im glad the pool designer jokingly brought up sub woofer's because he really wants them for under the covered deck. and they listens to alot of mainstream music and enjoy the bass so subwoofers are now a requirement ;)

I plan on using a separate amp for the subs. I should know better then trying to do everything on the same line.

i know that the 1260 has a lot more goodies in it, but i cant justify them for this project (except for the subwoofer) im good on the inputs for the 640. Unless you can tell me that the 1260 will give me a BJ and install its self for me

If that's the case, be sure they aren't mounted pointing up, best for sound but also best for catching leaves and spilled drinks. Be sure they are mounted in a surface, not just sitting up alone.... baffle, that's the word I'm searching for. Without a baffle, the bass will be really poor.


Love that!

Sell them a taser for their kids.

Add a subwoofer. Depending on level of crossover control, you can use an external device, or use one of several amps that have low pass filters built into them.

My favorite supplier can recommend several options and paths for you to consider. I would note that the control 19st is typically used as a fatten sound up, not add a ton o bass type driver....
