Do you guys think the RH450 will be enough to drive my LDS 15/6? My understanding is that the RH450 is somewhat under-rated in terms of the watts/volume ratio.

I have a gig coming up an outside stage, with little to no PA support for bass.

I do have my 112 stack but I really like the 15/6 outside. Super nice full sound.

Its an 8 ohm cab, so I think the amp gives 300w at 8 ohms. I have a peavey DPC 1000 that will give me 1000w bridged at 8 ohms, but I am trying to play the rh450 as much as possible so that I can get more used to it. Its also alot lighter and sounds better.

So "do you think an RH450 into an LDS 15+6 will be loud enough for an outdoor gig with no PA support" given that the amp gives 300w at 8ohm and the LDS 15/6 is on the power hungry side?

Hope that's better. :cool:

I'm far from an expert in outdoor amplification, but my armchair assessment is that you'd really be better off with two of those 15+6's; or alternately, getting a different cab for outdoor gigs, something 4 ohm and very high efficiency.

If you have PA support for the drums, I doubt the RH450 will carry unless you can get it pretty close to the audience. As far forward on stage as you can.

If there's no PA support for the drums (e.g. no mic'd kick drum or cymbals) you'll be fine. I took my F1 and 15/6 to an outdoor show where the vocals and guitars were all that was PA'd, with the drums really far forward on the stage, and I had more than enough juice.

So I think moderator intervention was to cool of the pending personal invective before it got out of hand. I started a show me thread for my own edification, but there is no reason this can not be the new improved LDS thread. Keep it clean and lets talk LDS cabs here?

Bassist, I have a 1515/66 order with Don I plan to power with a Genz 9.0. 450 x 2 I guess. Your 450 should do OK with a 15/6 but as you say it will push more in the 300+ area at 8 ohm. How bout runnin the preamp of the rh through your more powerful amp for lots of headroom?

IME neither unit you mention is really up to the job if by outdoor gig you mean playing to 100+ people with drums that have strong PA support.

But to put that comment in context - I felt the same way about my 400+ Mesa head w/ Ampeg 8x10 rig. If that rig would work for your circumstances then my experiences may be less than useful. I find that only Pre/Power Amp rigs satisfy in these conditions.

Outside [no significant boundary reflection] & playing to a crowd that strings out up to 50/75' away I need PA support or a rig that will emulate same. I play in a 3-piece hippy jam band with strong drums and need to carry parts from time to time with strong low frequency content [long notes that sound like organ foot pedal]. In order to get satisfaction at outdoor gigs I am using a 1515/66 +1 [dual 3015LF's, dual 6ND410's and a BMS horn] pushed by about 1,500 peak watts from a Crown Itech. Trying to use the rig you specify in those conditions would not work for me [inside & at modest volume I'd probably love it].

As an aside - If I had your rig and was doing outisde work I'd think about adding a fEarful sub [or another 15/6] and a power amp that'll do at least 2,000 watts Bridged into 4 ohms and using your head as a preamp.

Good Luck!

Well, I only do these gigs about 3 or 4 times a year so I don't want to buy more gear. Usually, these are festival type things where people are just walking by, but naturally some do stop and check us out.

I'll use the rh450 as pre into the poweramp and pump 1000w into the 15/6 and call it good enough.

...>>>Mr. Moderator Please Re-Open the LDS Thread :)

Amen!

I am always disappointed when I see moderators resort to the knee-jerk, ham-fisted reaction of closing a thread. It's an indiscriminate scattergun approach, not a rifle shot. It denies valuable information to everyone, especially the majority of rule-abiding readers, instead of truly punishing the offenders.

I'm not suggesting the job of a moderator is easy or even pleasant, but the tactics that should be used are deleting the offending posts and meting out appropriate punishment for the offenders (no access to the thread for a period of time, no more posts to the thread for a period of time, no more posts to the thread ever, no more posts at all for a period of time, etc.). Can't we use a scalpel instead of a meat cleaver, especially for the more popular threads?

Infraction or not, it makes sense. I don't see what's wrong with arguing some relatively harmless opinions, as long as it's done with general civility. It seems like this forum just hates any sort of mild conflict, like it can't be a healthy thing sometimes.

I guess this is the new LDS thread...? :o

We do try to edit threads that aren't damaged beyond repair, but there does come a point where the best option in a thread that's gone generally bad is just close it to let it die. And in doing so, no information is "denied" to anybody - except deleted posts, of course, which is a separate issue to the thread's closure.

Sometimes editing a thread is either impractical or just generally not worth the time and trouble. When people want to restart a civil discussion, they can start a new thread (like this one).

Some of the suggestions above for moderator action sound interesting - at the moment the software isn't set up to allow us to do most of these, though. Perhaps a thread in the "Suggestion Box" forum could be a good way to get discussion going about the possibility of making these workable. Or you can discuss moderation issues for particular threads via PM.

Thanks.

In the meantime, I'll ask my question here...

Depends on the nature of the outside location, the type of music, and the volume level needed.

I've done Jazz trio gigs outside for relatively large crowds with a little GK112 and no PA support where the gig had a brick wall behine it and the band was directly on the street pavement. I've heard other bands outside in 'fields' on raised stages with massive PA support, and the bass not covering past the first 50 feet.

It depends! The RH450 and the 8ohm 15/6 should be able to easily keep up with all but the loudest unmic'd drummers in any acoustic setting, outside or not.
