The boys might need more information about your speakers and amp.
Eg model number, make etc
Qualitiy of amps make a big difference.
What type of music / band are they used for??

The answer to your question is yes BUT you are underpowered

(PS saw the change from 800w to 700w you were quick)

Gadget

Ya like Fanman says more info.. but if the subs are 8 ohms, go bridged mono and parallel the subs... but run 2 sets of wires from the amp, not daisy chain if possible...
Make SURE they are NOT 4 OHM as in subs with 2 8 ohm woofers...

Holy crap! This changes every thing.
Invert the wiring on one of the speakers (one cab only), then turn that cab backwards. Place the cabs side by side on the floor. The front firing sub will pulse. As it does the rooms air flow will create a vortex. The pulse of the reverse firing sub (still to the front of the room) will exit through the unused 1/4\" jack(s) like a bullet shattering the vortex, sending a shock wave evenly to the entire room. This method (developed by the acclaimed Swedish scientist, Edghart Shloshel) has been proven to reduce the power requirements and gross number of sub cabs. The placement of the \"Shlosel Two Cabinet Max-Wave\" configuration is sensative to the dims of the room. Dr. Shlosel has developed a simple program for Windows (sorry Mac users). You can get this for less than the price of one quality sub. Only $425. PM me and I'll give you the PO Box to mail the Postal money order to.

The views expressed........ :roll:

Geez thanks mr. dra... the moneys on the way....

Hi Dra
You must do a lot of reading to have all that knowledge.

\"like a bullet shattering the vortex\"

Very impessive.

\"This method (developed by the acclaimed Swedish scientist, Edghart Shloshel)\"

A very well know scientist (Did you know that he unfortunatly died in May of 2007 (RIP)?)

\"Only $425.

Is that in US dollars?? (can I post Australian dollars?)
Sounds cheep to me!!

Have you made any money yet??
How many PM's did you get??
Mark

PS What was the model and make of speaker again??

And if you add this amp:

available here...

For somewhere under $300,000 US dollars, provides that added benefit of killing all weeds, ants cockroaches fungus,plants animals, children adults under 6 feet tall, TV's, appliances, fries all wiring within a 10 mile radius, sets up an EMP that will disable all air traffic, cars, trucks, motorcycles, and golf carts within a 1000 mile radius, and contaminate the soil so it can't grow anything for 400 years. All adults over 6 feet tall will be sterilized, and walk around dumbfounded sporting permanent \"Rock horns\" muttering \"DUDE that was AWESOME\"!

:shock:

Yes his passing was sad, but we can honor his memory by purchasing his genious in the form of this software package.
I too, to remember his legacy, will have a two sale. $400, and if you know his beloved Austalian Shepherd's name, you'll get an additional 25% off.

So far not a lot of response from this forum, but the guys at PSW are lapping them up like Shlossy. ( :oops: crap!)

PS - I find the Belchfire a bit underpowered for my needs. I run all my cabs in series and the BF only puts out 96w at 512 ohms. What I need is the new Vurpfire amp. It actually increases output as the load decreases. (Something about the re-configured Flux-Capacitor) First full production run is April, so order now.
