2 very efficient 15's or the 2 15s + 8 10s for pretty large room (no pa support)

[frankz]

Have a gig this weekend and the PA support is only vocals but room is pretty large 750+ person venue (big for kansas) anyhow probably neither will sound wonderful but i was wondering if id gain anything by adding my old 2 4x10 cabs (acoustic newer ones)

my 2 x15 is running kappalites like 101 spl so really effiecent with watts bridged my crown 402 might be 1000 watts tops..

anyhow i could run my 2 old 4x10 cabs on one side of amp @4 ohms and the 2 x15s on the other (they are 4ohm wired also).. that would move alot of cubic inches but the acoustic 4x10s are probably like 88db spl so not as effiecent but that would let me for ex put the 2 15 im middle and one cab on each side kinda angled to cover the room a bit better...

would that be the way to go

or would i be better off just using the 2 x15 its in an old 1977 vented acoustic cab.. the speakers should be @450rms each 900 peak plenty strong enough to handle the amp.. id loose some top end but we play blues and have a hammond player so not a huge deal

guitar player will have 2 or mabey 3 tube amps.. fender 60watt and a mesa rocket 44 and mabey one other

anyhow just wondering (cabs are in different locations (home and rehearsal) so ive never chained them togather like that..

anyhow should i just take the 2 x15.. would that be louder actually bridged... or do the back breaker and bring it all... and have less watts and 8 less effiecent speakers but moving lots of inches of speaker...

gigs friday (tomorrow) ... and for those that might have read previous question I did get the 2 x 15 cab sounding lots better... so it wont be crazy boomy or anything

hope that wasnt too garbled of a question tried to word it best i could...

peace

so summary

2 x15s 101 db spl bridged 1000 watts kappalites

or those running at 400 watts and 8x10s probably 89db spl on the other channel running 400 watts.. 800 total

[staindbass]

thats a tough call. can you test it at home before the gig? to see which sounds louder/stronger. 750 people is alot with no pa.

[frankz]

it wont be full like that.. its a red cross benifit and they cant pay the normal sound company that does the venue.. that is just the room rating size.mabey 200 people or so... if it helps to give picture the room is an old moose lodge curved wood ceiling and hard floor... very overly bright sounding room... even thinking about running the drummers kick thru a my amp.. (not cranked) but just to give it a bit more

yep gig is on low budget but its for the Missouri area (tornados) just trying to do best we can with what we have

ironically the building has a killer house light show as they do live shows all the time its just that the sound company will want way to much... so its just 4 speakers on stands (sp2) type and mixer power amps for vocals

cant really test.. well again its a free show and i have the 8 10 at my house and the 2 15 at rehearsal... i just move the head usually.. and to move it all.. which ill do once.. but will require carrying up stairs and such.. basically alot of work if id be better off with just the 2 15s

[nysbob]

I'm not a huge fan of running different box configurations off one head without at least checking phase.

I've done countless gigs like that with just a pair of 15"s, but of course YMMV.

So its a red cross benefit and the sound company won't show up to run the show? What a bunch of d**ks.

Any way. i think run the 2x15. It seems the most efficient and you've tested it.

[frankz]

well that makes 2.. for the 2 x 15.... was hoping someone would convince me to carry my cabs up the stairs so i could play pretend hendrix for the night but probably best to keep it simple and if it boils down to using the most effiecent speakers as long as they handle the watts.. its a no brainer.. just thought might get some sorta (bigger effect) by moving more inches of paper..

thanks

far as the sound co.. i think they run several places and probably have choice between doing a paying gig or a free one.. and probably would have to move some speakers and such to do the gig so i cant blame them (gas prices and all) sorta one of those deals.. even if they do it super cheap.. well now youve paid someone 150$s to wiggle knobs and the bands are working for free.. would just cause bad vibes and well.. i always hate when the sound man tells me to turn down my amp... so its gonna be fun to finally play full tilt

[Never_grew_up]

Mixing speaker sizes without a crossover can turn out poorly. You'll move more air with the 2-410's than with the 2-15's. Even though you describe the room as 'overly bright', with a hard wood ceiling and a hard floor I'll bet there are lower resonant frequencies that are going to be hot as well. Probably somewhere around 80hz, and again at about 250. I'd probably go with the 2 410's so that you can stack them and get some sound up at ear level.

so summary

2 x15s 101 db spl bridged 1000 watts kappalites

or those running at 400 watts and 8x10s probably 89db spl on the other channel running 400 watts.. 800 total

I have never been half as concerned about phase issues with different sized drivers as some others here, I am certain that this is a case of the more speaker area you can carry (assuming your cabs pass the battery test for phase IE + to + = speaker cone moving forward away from the magnet) the more sound power you will have, whatever the watts, within reason.

[will33]

I say just bring the 215 as well. It'll handle it. In a situation like that once you start getting louder than the drummer it hurts the overall mix so match levels with him and let the bleed through the vocal mics do what it does. It's about the best you can do if the drums aren't mic'd. Have a trusted pair of ears out front giving you the up or down sign for volume.

[funkinbottom]

What they said. Go with the 15's. I've played some fairly large rooms with my single 15 no problems. So I think you'll be fine.

[Aussie Player]

I do and it is the very best set up.

A "no strain" bass amp is the most wonderful experience you can have on stage. Take them both and enjoy the day for yourself.

[Caca de Kick]

You can use either one indoors just fine. And if it's for a Red Cross event, you're not going to need any ear bleeding volume.

I have a 2x15 and an 8x10. My 2X15 will carry any indoor venue in a LOUD band and no PA support. The 8x10 is overkill indoors.

[rpsands]

I'm going to say bring it all and only plug in the 2x15 unless you've got volume issues during the soundcheck.

[gnjpowell]

Go with the 2x 4x10s

[BassmanPaul]

Even though I'm not a fan of the Red Cross, way too many negative experiences with them, I'll give you kudos for participating in a charity gig.

I'll add my support for the 2x15.

[AwkwardLoudness]

Either use only a 2x15 or both the 2x15 + 8x10 but face the two cabs in different directions at least 90° apart.

I doubt you will need both rig for the volume if your drums are not mic'ed.

However, if you are determined to have the loudest rig possible, consider this.
Only if the said 215 can take the 1000 watt without power compression; and you are confident that the quoted sensitivity of 101dB and 88dB both being fairly accurate. Then use that 215 by itself.
Otherwise, take them all.

[will33]

The volume limit is either what the vocal level can get to or the unmiced drums. Just make sure the vocal can be heard/ lyrics understood, match the instrument levels with the drums and it'll sound fine out front after it's all washed together.

[derridiandrift]

Ya, the 2x15 will be fine. You're going to bury the drummer as it is. If you bring an 810 along it will make matters worse.

It seems to me that the musicians are always the first ones willing to work for free when it comes time to stand up and do the right thing. I can't believe you haven't found a production company willing to do one for charity. A band-in-the-box vocal PA for 750 people is going to be a bit lame. But when you're fundraising, you make it work.

[frankz]

just wanted to sorta conclude.... i ended up taking all 3 cabs and had a hour or so to tinker at the venue... what i ended up with was running the 2 4x10 cabs one on each side of the drum riser... probably like 15-20 ft apart... the 2x15 was on the inside side of the 4x10 .....on my side of stage..

ran the amp 1 channel the 2 15 the other the sealed cabs kinda a tight vs vented cab Eq (setting control)

we used 2 of those yamaha mixer amps with 2 pair of speakers and were able to get some drums thru one of them.... worked out not wonderful but we were able to fill the room sound if a person didnt know better they would have assumed it had reinforcement i would think

anyhow was gonna take pic of setup but forgot just wanted to conclude

later...... and thanks again

PS.. yep aussie we had a song (midnight rider) and do the Allman bros extended ending version... and it was awesome to get really quiet and then shake things when it kicked into the slow blues part def made it fun now gotta find some light weigh neo 10s thinking avatar so i can make a rig i can carry prob just go 1 4 10 though
