blues duet

[bass30et1]

Hello,
I play double bass in a blues duet: singer/folk guitar and so myself on acoustic double bass.
We play on around 50 people pubs and around 100 people outside places.

First suggestion, thanks Seth, was a pair of SLA Pro with a pair of Titan 39 or possibly a jack to avoid the need of a sub.


I will go for the SLA Pro, witch seems easy to build, but Titan 39 are too big for my car half feeded with the double bass itself.
Can a pair of tuba 24 make the job with a decent projection?

Let's dig a little deeper into what you are doing......do you use a bass amp onstage? Or, is everything going to go through the PA?

If you are only running bass through the PA, then you will need a sub or run Omni 12 Tall boy as a one cab solution for the everything. It really depends on how loud you are trying to get. I would think a duo wouldn't need to be all that loud.

While Jacks are an option, once you put 'em up in the air, the bottom end is gone.

You could build a single SLA over a single T24 or T39. Put it between the two of you and not even need a monitor. That's how I do my acoustic duo gigs on outdoor patios (I just use a single SLA Pro). Start with one of each, then add another SLA if you need to in the future.

Despite its name the double bass doesn't go all that low, so it doesn't need a lot to handle it, plus you have its acoustic output. I'd go with a pair of Jack 10.

The limit of power i have on stage is directly linked to the feedback of the double bass body, so limited.
I also often cut bass frequency from 80hz for the same reasons.

I cannot push my amp enough for the audience, so yes the PA have to handle part of the double bass.

A driverack is on the game and can manage filtering, eq and separate signal for all enclosure as needed

A sub would make it worse.

Thinking about amping the SLA Pro and Jack 10 in the most affordable / best in quality / compact to travel, what do you think about:
Build each Jack 10 with an air head to log an QSC RMX 850 ( already have one)

SLA Pro in 8 ohms will have 200 watts

The Jack will have only a 10" driver, no piezzo, no filter.
Can i put a 4 ohms to level up the power it will have to 300watts? Better headroom and a little more power for outdoor purpose

[Bill Fitzmaurice]

I'm not sure what you're getting at. You would not use SLA Pro and Jack 10 together.

[bass30et1]

The first proposal you made me is a pair of SLA Pro and an associated pair of jack 10 to manage the low end without sub.

Qsc rmx 850 has two channels:
2x200w @ 8 ohms
2x300w @ 4 ohms

I propose to use it:
1 SLA Pro @ 8 ohms for channel 1 so 200w from the amp
1 Jack 10 @ 4 ohms for channel 2 so 300w from the amp
(If impedances can be mismatched on the amp of course)

[Bill Fitzmaurice]

Nope. Your either use a pair of SLA Pro with a sub or a pair of Jack 10 without a sub. You don't use SLA with Jacks, Jacks are not subs.
