Dunno about Max SPL, but these are still running.

If you calculate it, you get 122dB, assuming not too many of those watts are converted into heat. SPLs aside, they'll still sound awful.

If you calculate it, you get 122dB, assuming not too many of those watts are converted into heat. SPLs aside, they'll still sound awful.

From another site, agreement with Tony's figures:

To clear up a little bit of confusion here, the number of Watts that a speaker can handle before going up in smoke has absolutely no relation to the amount of sound that it will produce. The marketing people won't tell you this as it's far easier to produce an inefficient speaker that will tolerate 1000W than an efficient one that can manage 300W.

The figures to look at are the maximum SPL, or if that's not quoted, the sensitivity. If the manufacturer doesn't quote either of those, they have something to hide so avoid them.

By my maths, the Peavy Pro 15 you mention will manage a maximum SPL of 122dB, which is not great. The top cab in the HK soundhouse that was mentioned will coincidentally also manage 122dB (Its amp is only 150W but the cab is more efficient). See the problem with just looking at power ratings?

The EV SX300 mentioned quotes a calculated max SPL of 131dB. Note that that's calculated, not measured. My maths puts it more realistically at 123dB. (Personally I think they're horrible speakers - worse than fingernails on a blackboard but plenty of other people seem to like them).

As a comparison, a really good (expensive) cab such as a d&b Q7 is only 400W but manages 138dB as it's maximum SPL. That's getting on for three times as loud as the Peavy. To further confuse the issue, dB is a logarithmic scale; it takes ~10dB increase for a speaker to sound twice as loud. A 3dB increase consumes twice as much power and makes a negligible difference to the volume.

Ultimately, you need to listen to whichever systems you're considering. Paper figures will only ever tell part of the story.

As to the sound, well Tony isn't Peavey's biggest fan. ;) Crazy K is. :D
I've heard them, in my opinion, Class D win on quality, and lose on volume. Hey ho.

"Awful" is a bit strong.

I've heard a lot of budget speakers in my time, and owned quite a few :o , and in the sub-£250-a-pair bracket these are pretty good value and sound quite sweet on their own at smaller functions, or paired up with pretty much any reasonable sub(s) for anything up to a couple of hundred in a a typical venue. Now if only they could make the carpet stick properly... but that's a whole other thread :)

Good value they are Vectis. If I wanted max volume, these are high on the the list. However, if I wanted a sound I really liked, C****-D. :D :D

Thanks for the replies Guys.

There are a few sets i'm watching on Flea Bay Pete (the ones you highlighted earlier. I'm also a fan of Cl:Censored: ss D as you are aware of my current situation and just sold 2 x pairs of CD 158- 1's (Badged up as AC EURO).

Soley for the fact I still have my large main rig with the T AMP 2400 (fantastic) and the JBL's

BUT i have a smaller project where I wanted to keep things light (2 cabs) compact (Mixer amp) and get as much power out of the mixer amp as possible.

Therefore I purchased this mixer amp (had a good deal) :)

http://www.bluearan.co.uk/index.php?id=ALTPBM8500&browsemode=category

Now the spec sheet on this states output

2 X 500 WATT Rms @ 4 Ohm
2 x 300 WATT Rms @ 8 Ohm
Bridge Mode 1000 Watts

So to get maximum out of the amp I need to run a 4 ohm load (options limited)
And because I need to keep things simple I don't want to be running 4 x 8 Ohm cabs in parrallel to achieve a 4 ohm load (defeats the object).

So trying to keep in a sensible budget and relating to the above it dosen't seem I have much option other than the PRO 15's

Any suggestions greatly appreciated :) :) :)

As soon as we find one, we'll let you know. ;) Now if I can just find an amp for myself, I've cracked it. :( :(

You've missed the salient point there, I want one with an inbuilt x-over, otherwise there'd be a T-amp heading over here as we speak. :D :D

Well it's decision time guys :confused: :confused: . as I state my options are limited at 4 ohm. So hopefully within the next 24 hours it's gonna be the Pro 15's

OR

I have another theory to explore, there are some reasonably priced JBL JRX 115's also a pair of JBL TRS 125's and finally a pair of JBL MR825's

Now this goes against my original 4 ohm plan as all the JBL's are 8 Ohm

BUT :D :D :D

The amp gives 300 watts per channel at 8 ohm, most of the speakers above average 250 watt rms. BUT in terms of SPL the JBL's are a more efficient speaker capable of producing higher volume's


Any more views before I part with my hard earned Rubel's :confused:

:D :D :D :D

Although entry level, the JBL JRX series give a great bang for your buck and sound pretty decent for the small price ticket they carry. I always highly recommend them to anyone looking for a good budget speaker.

The JRX115s are 250w at 8r, therefore your amplifier is somewhat underpowered. Be careful not to send a clipped signal to your cabs as you'll destroy them. I happen to have a pair of returned JRX115s next door where the DJ did exactly that.

[Totally Plucked]

The JRX115s are 250w at 8ohm,

Been looking at info on the net JBL recommends amplifier rating for these cabs at anything between 250 watt and 500 watt Rms.

Would be pushing 300 watt per channel rms into them so should be ok with just a tiny bit of headroom :) ??

Did read on some forums that the JRX115 series suffered with horn problems (I know the feeling :D :D ). ??
But if they are only 250 watt Rms, it makes you wonder what some of these people push through them.

It appears the MR series are a step up from the JRX versions

[spin mobile disco]

I used the Peavey pro's and had no problems with them .They sound good. Not sure about maximum spl but the efficiency is about 40% better than the equivelent class D.
Last class D I demoed was about 94db the peaveys are 98db I found they coped well with up to 100 people at an 18th with no problem I was feeding 300 watts rms per side into them.
I only got rid of them due to the weight as I hurt my back and went over to lighter cabs. But as the class D and peavey weigh in at similar weights I guess its really personal preferance.
I would say Peavey are better known than class D.
Forgot to mention the ev are rated higher as they are a 12" cab where the peaveys are a 15" the peavey has to move a larger diaphram for a given amount of power than the sx.

I've been pushing about 350w RMS into a pair of these using a W-Audio 1300 amp and they produce pretty good volume (I've used them at Gigs with about 300-400 people with a pair of JBL JRX118S bins and they've been fine, but I'll typically just take the tops to anything with < 150).

This is where it gets interesting - they're 250w RMS, but JBL reckon they can withstand anything up to about 1kw based on their own 100hr tests, hence the recommendation for a 500w RMS amp. Because of this, people have a tendency to buy much bigger amps (600w+) and drive them to the limit, and that's when horn damage happens.

the clue is in the pricing Gary... list price on two stacks of C7 with proprietory amps (2 No. D12s) is over £20,000 ex vat

I didn't click the link so didn't see the prices. Fair play.

Apart from secondhand gear, you won't find d&b pricing on the web. The six UK sales partners provide bespoke quotations for serious enquiries. No one pays list price, different companies will pay different prices. It's the way it is.

Lol - The JBL's, JRX115's. Peak SPL from them is 128db, which is reasonable...

Reasonable but not realistic. That figure is a calculation with two flaws, namely (a) it is based on the 1w/1m sensitivity of 98dB and the driver's rated peak input power handling of 1,000w, which would only be sustainable for bursts of a few ms, and (b) it is assuming 100% efficiency, i.e. none of those watts being dissipated as heat.

A realistic continuous SPL for that box is 122dB. But, don't be put off by any of that - as I've already said, JRX are good budget boxes all the same (and they don't rip your face off, unlike their older relatives, the EONs)

:eek: :eek: :eek:

Isnt that a bit extreme Tony---im sure we all have run our speakers in the red light area many times by accident or design. :confused:

Running like that all night long may be a different matter of course.

Makes Pro 15s sound positively attractive---havent managed to destroy mine in 5 years despite trying with a variety of led patterns in red --:D :D :D

Note this carefully Mr Totally :)

Maybe mine are destroyed and I cant tell:Laugh: :Laugh: :Laugh: :Laugh:

Im sure Peter will have some good stories in this area;)

I think this is the problem with the JRX's - they have a low RMS value, and a very high peak value, so people typically match them with a much higher power amp than the RMS value - which is Ok as long as the cone is moving and keeping itself cooled, but if you run any part of your Rig continuously in the red, you can quite quickly melt the voice coils.


Thanks for your advice Jules, and your honest opinion as a speaker ?

I'm really pleased with them - like most MDF, carpet covered speakers at this price point (Peavey, Class-D, etc) they're fairly big and heavy, but they have a nice sound and give a reasonable output. A1DL - I agree with your comments, the figures I quoted where the manufacturers ratings, which I guess should be used if you're comparing like for like.

RESULT :D :D

Not 4 ohm, but 250 watt rms at 8ohm and the amp is 300 watt per side at 8 ohm.
So will seee how it goes !
