Morning All,

I'm away from home at the moment, staying with my folks for a few weeks and I've got my bass with me. Rather than bring my cab (a cheap but good GK CX210) I thought I'd plug my amp (Little Mark III) into one of my dad's PA speaker - a Peavey Eurosys 15" thing. It's fine, I'm just using it for practise and it does the job but... IT SOUNDS TERRIBLE! I can't believe something that big has such a crap tone and how good my GK cab is by comparison. You could certainly gig with it, but it just seems to have an unpleasant low end and makes the bass sound rubbish . Anyway - just thought I'd share...

Using the wrong tool for the job rarely ends well.

Yep. Well, it's good to experiment and if I'd never tried I'd never know. Also - didn't have to take a bass cab 250 miles so that's saved some hassle!

If anything it should illustrate how a bass cab is coloured to focus on a particular range of frequencies, wheres a PA speaker needs to be able to cover the entire spectrum.

There are PA cabs that work with bass, and those that don't. It's not just about the cab, it's about the bass tone you're after also. 

Indeed. This is fine for practise and has saved me the hassle of transporting my cab but it's been very interesting to try. The Peavey HiSys is, after all, a 30 year old cab though still has a BW in it.

Given that a PA cab of sufficient quality, not to mention size, to reproduce bass properly costs as much as a decent bass cab and is no easier to transport, one may as well use the right tool for the job.

Some PA cabs work very well for double bass, such as QSC. Some are even an improvement on an out and out bass cab in that they offer a wider tonal range.

I'm a bit confused now as to which one you've tried? The Eurosys stuff was pretty naff IIRC, whereas the Hisys range was a big improvement - as you say BW speakers etc. I've used the Hisys 2 as a bass cab a few times when I had to and found it okay, especially with the horn in it's 'flat' setting.

My RCF 732-A (a £600 powered PA speaker) is better than and cost half as much as the Barefaced & Genz Benz rig it replaced 😊

My double bass has gone through many a set of PA speakers with no issues. Obviously it helps if the sound guy knows what they are doing. I had one amp head fail around 2010 where I had the same predicament with a bass guitar. A good DI box is usually the answer and will certainly get your tone sounding closer to where you want it.

Sorry, looked again and it's HiSys... I'll take a pic.

Yeah, I don't think these are up to RCF standards!

Here you go. It's hard to describe what's wrong with it, it's just lacking in richness. It makes my bass sound unpleasant and makes me not want to play it. It's amazing that a £260 GK 2x10 sounds so much nicer, though it's about 30 years younger so the technology's moved on.

I use one of these and it is fantastic.

Not really, the two cabs were designed to do different things

I think Brian Wilson needs to get out more....

And yet some people get really good results out of PA speakers - there's a lot of love for the RCF 732-A in this thread.

Maybe your bass sounds awful through your amp, but your GK cab's voicing compensates to make it sound good. If that was the case,  the Peavey cab is just being "honest". It's a shame there's no headphone out on the amp to test it. Have you tried running the amp's line out into an interface/desk?

I've got one bass that sounds great through a DI box. I've got another that needs plenty of EQ from an amp and/or cab to sound great. Neither is better or worse than the other - just different ways to achieve a good sound.
