| At our church I play steel as well as lead guitar on some songs. Occasionally there is a song that needs a bass played. At a lower volumn, since my amp is miked, could a bass guitar be played through my 1000 without causing any problem... |

The more knowledged please respond, but I'd be careful about (if not all out avoid) playing bass thru ANY open back cabinet amp.
I've done it (bs. thru a guitar amp) when in a pinch, but it's still not healthy for the amp. |

I have played Bass thru my friends Nashville 1000 at practice..but I won't play Bass thru mine ! 
I think if you are playing at moderate to low volume you will be fine..the issue here is the cabinet is not a BASS cabinet and with the open back as mentioned above you can pop the speaker in a heartbeat. You will be able to tell immediatley if a problem is brewing.You'll hear it.
Suprisingly though, and this really caught my attention..On my last visit to Nashville and visting the clubs on Broadway I noticed one of the bands Bass players was playing thru a Nashville 1000 and at a pretty good clip..SO ..who knows maybe this amp is even more rugged then we give it credit for.
Remember the old Fender Bassman's ,the original 4x10's ? They were open back cabs...and they sounded great at moderate to low volume, which is actually all they had.
I've always wondered why Peavey didn't use a 1/4 inch plug for speaker connections which would make it possible to use an external cabinet in situations like these..
Keep the volume low and I think you will be fine..I would even do this with mine..

| I would avoid playing bass through the Nashville 1000 if possible. But, as you can see, many players take that chance and all works out fine. I know that the components that make up the Nashville 1000 will withstand the use, but the overall design might not be so forgiving, ie; open-backed cabinet, etc.. |

Could someone please give a brief, layman's explanation of why open-backed cabinets are a 'no-no' with basses, i.e. why it can pop the speaker so much more quickly than in a closed-cabinet? Thx,

Jim:
In strictly layman's terms, the bass notes drive the speaker cone and voice coil outwards (toward the front of the amp) a larger amount than do the higher notes such as those produced by a guitar. With a closed back cabinet, the air behind the speaker is rarified when the cone moves forward and compressed when the cone reverts back, thus acting somewhat like a shock absorber. This prevents the cone from moving far enough to damage the cone. Closed-back cabinets usually have one or more bass ports near the bottom of the cabinet which allow the air movement from the back of the speaker to escape toward the listening audience in a somewhat controlled manner -- i.e., since the ports are rather small, they allow enough compression behind the speaker to absorb some of the rearward energy, while still allowing some of the lows from the rear of the speaker to join with the energy out of the front of the speaker.
Now, expect some more technical explanations to follow, challanging my layman's explanation.
Love your work.

The problems with using open-back cabinets for bass has to do with the type of speaker, maximum cone excursion and controlling the air. The typical open-back cabinet for lead instruments has a speaker with a lighter cone, designed for less cone excursion. If a bass instrument is used, the cone can move beyond its safe limits and be damaged. The open-back cabinet can permit the front wave to cancel the rear wave from the speaker, resulting in reduced bass output.
In a modern bass guitar cabinet, the speaker will typically have a heavier cone, greater cone excursion and the box will be tuned and ported to enable the speaker to produce high volume levels at lower frequencies. The correctly-designed cabinet will actually cause the speaker to produce greater volume with less cone excursion.

Well I think the real reason that open back cabinets were first used is because they ran out of wood.
Current manufacturers now have enough wood , wood screws, felt and glue.
