okay i finally purchased today:

Peavey 115bx (black widow)
&

Peavey 410TX 

(350 watts each) a total of 700 watts... i only paid $25.00 because i traded in about $900.00 worth of equipment that i know i wasn't going to use... I've played it at the stare called music go round, and it had the walls shaking, nice tone etc... now i need a good head amp to go along with this...

If I were in you shoes I would now only let my finaneces determine which hear I would get. What I've learned about Peavey is that they will last.

I would stay away from the Max series heads. I had the max450 before I moved to eden. The main reason I wanted to get rid of it was because it lacked power. I had the 210 and 115 cabs both at 4 ohms, and my head was suppose to be pushing 450 watts at 2 ohms. I never felt it. I've read reviews on these heads and that's what customers are dissappointed about. You will fair better with the Tour series head or maybe go with a pre-amp and power amp setup. It all depends on your financial situation. As far as the cabs, you have more than enough cone surface to make people's pace makers go haywire. I know that I speak highly of Eden alot, but I can honestly say, Peavey makes great equipment that is affordable for everyone. They've been around for many of years and will continue to be around.

I'll assume both of these cabs are 8ohms?

Max 450-which has since been discontinued



Tour 450


I haven't played the tour series head, but looking at how fast the Max hit the scene and then left, I'm sure the Tour series is much better.

Oh ok. I like the tour. If I didn't have a bass pre that I am crazy about and plan on mating it with a power amp, I'd be getting the tour 700.

I'm reading a lot  of bad reviews of the tour 700... saying that the power goes out for like 10 seconds, and you don't get a full  sound i was thinking of the Gallien-Krueger 700RB-II Bass Head which has nothing but positive reviews on it.

If the 15 is 4ohms, don't plan on using them together unless you get an amp that goes down to to 2ohms.

Take the 15 back if its 4 ohms and get an 8 ohm cab.

Those are good cabs and a classic setup.  But yeah, you should switch out the 115 like dd was saying so you can play them together for a total 4 ohm load, or you need to get a 2-ohm stable head.  )Short of it is, that won't be optimal either for these two cabs.)  Those heads are harder to find and usually (not always) cost more.

Adding the cabs together will draw more from the amp and will give more speaker surface area, so it will be louder.

all this ohm is still new to me.. so the lesser the ohm, the more powerful the sound. the 410 is powerful by itself, so will the 115 effect the power of the 410? ?/?

Guitar Center has these amp heads by Mark Bass Little Mark II. Phenominal little head I need to get one myself after the new basses come in. They are like $550.




Aslo another nudge in replacing that cab with another 8 ohm. Reading through this thread, there is a lot I could say, I've been doing sound reinforcement over the last twenty five years, and designed the system at our church so there are a lot of considerations to be made. Recently I have downsized my own rig, I am not playing out as much and the majority of the venues (including churches) have FOH support these days. At my church (A frame building seating 1200) I was using an Aguilar DB750 feeding a Bergantino NV610 monster setup. The band consist of a drummer (miced not shielded) two keyboards (FOH & monitors) guitar (FOH & monitored) and my big rig with no PA support I had plenty of volume to fill the house up with my rig alone, but because of stage volume and not over powering the backline, I could'nt get above 3 without over powering the vocals and muscians,and if one turned up everyone would in turn increase volume until it was blaring and sound check was a was of time. Rule of thumb is with PA support stage volume (backline) should never bleed or supersede the FOH volume, so at that level I could hear myself we had a great mix, but people in the last 12 rows said they could not hear me at all. So, I downsized and began using my ThunderFunk amp mainly because it's soooo much lighter, using only a Epifani UL210 for backline while sending DI post EQ to the FOH that hosts bi-amped 3 way EAW concert series mains, and EAW dual 18" subs, now I am being heard and felt in every seat in the house while not over powering the backline or the FOH, and the complements are coming in. I still maintain a monstr rig but the point here is that it is not always necessary or good that you over power your band mates. Although I should have known better I insisted on having my big rig because I didn't want my sound alterd my the inexperienced guys unstairs, but working with them has it at a level now where everyone is happy and levels are under control.
Sorry to derail the thread, but as the OP stated that his hope was to be at a church with 1200 plus capacity, more than likely when you show up with all your gear they may say we have DI and IEM or cans, you can leave all that in your car. After years of carrying gear you will say Thank You Jesus!
Try and select a head that has DI (post and pre) or a good DI box and hopefully you can trust the guys upstairs.

Ohms are just a measure of resistance to current flow. So the less ohms the easier current can flow and and vice versa. As far as adding the 1x15. if you are adding it to a seperate channel on the amplifier it will usually have no effect of the performance of the 4x10. but if you are going to daisy chain it from the first box on the same channel it will lower resistance and cut the wattage proportionally to the ohm ratings of the two boxes. For example If I have 1000 watts going into a 8 ohm 4x10 and added a 1x15 at 8 ohms. Since the two are in parrallel the overall resistance the amp will see is 4 ohms and both boxes will get 500 watts.

Say your amp has it's rating at 4ohms minimum..............

One of your cabs is 4ohms already! If you add that 8ohm cab, the results will bring the combined ohms down to 2.67. That is below the rating on your amp. Your amp is designed to operate at NO LOWER than 4ohms. Do not use those 2 cabs together.

Another thing...............

Most amps have 2 wattage ratings. 1 at 8ohms and 1 at 4ohms. The 4ohm rating is usually higher! So the above statement is incorrect. If the amp gives out 1000w at 4ohms and you use 2 8ohm cabs (giving you a 4ohm total load), then yes, both cabs share 500w each. The wattage increases as the ohms decrease.

so basically i need (2) 8ohm cabs and and good amp that has 4ohms - (and what does ohms stand for?)

okay i think i'm starting to get it. so for the best results, i can just leave the 115 out of the picture for now and play with the 410 8ohm in the meantime?

Yeah you can do that. My cab is 8 ohms and running my head bridge into it. I have room to add up two 3 more 8ohm cabs if I want to.

I hope I don't confuse you with this, But here goes.

 Ohm's Law defines the relationships between (P) power, (E) voltage, (I) current, and (R) resistance. One ohm is the resistance value through which one volt will maintain a current of one ampere.

( I ) Current is what flows on a wire or conductor like water flowing down a river. Current flows from negative to positive on the surface of a conductor. Current is measured in (A) amperes or amps.

( E ) Voltage is the difference in electrical potential between two points in a circuit. It's the push or pressure behind current flow through a circuit, and is measured in (V) volts.

( R ) Resistance determines how much current will flow through a component. Resistors are used to control voltage and current levels. A very high resistance allows a small amount of current to flow. A very low resistance allows a large amount of current to flow. Resistance is measured in  ohms.

( P ) Power is the amount of current times the voltage level at a given point measured in wattage or watts.
 
Ohms represents the amount of resistance in circuit. The circuit being  your power amp and cabs. The lower the resistance the higher the power. The higher the resistance the lower the power. I hope this has helped :)
