Look at this Ross http://www.thomann.de/gb/tamp_ta1050ii_endstufe.htm

I got the 1400 version it's a fantastic workhorse, reliable and plenty of power.
The 1050 is the same pcb and basic amp but lower power. For £131 it's a steal, looks like good bit of kit. Worth a look! :)

Ross,

I think many people here would recommend a pair of Mackie C300z speakers.

They appear to be available for about £350 a pair here:

At the time of posting, their site is down, so you will have to check the link later.

:)

Ive found an amp now so looing to spend £300 on speakers.

[Corabar Steve]

Don't look too bad, those speakers will be good for mobile discos
Have you had any experience of JB Systems speakers then?

[DMX Will]

Have you had any experience of JB Systems speakers then?

They're rubbish.

[Solitaire Events Ltd]

They're rubbish.

Care to expand on that Will?

[ross@rds]

[ross@rds]

Thanks for the help guys pair of these im gonna get -

[Vibrant Sounds]

I've had both of the actives PA302As and PA502As. Both are 400watt bi-amped active powered speakers with built in EQ. The PA502As are more expensive and have a better low end sound due to their 15" drivers, but they are bleddy heavy at about 34kgs each. The PA302As are a similar spec to the Mackie SRM450s but with a lower SPL, good speaker though and they will do a good job.

With a three year warranty, you will not be disappointed,

Mine turned up last week, Took them to a gig last night was impressed to say least only had them up half way and no sign clipping nice n clear, And handy thing is if people want to do wedding speech's they can plug direct into them to save them using your mixer etc, Or could hire them out for confrences. Only thing i would say is i wouldnt gig them on there own, I had them with 2 carlsbro gamma 15's and the box 15" sub sounded sweet, I will listen to the 12's on there own start of the night tonite before adding rest, Mind you on the floor at start of night with shaggy on nice bass line but you loose it on tripods, Worth thinking about if you havent got anythign else to run with em go for the 15's or add the bass bin you know you want to

Shouldn't you look at an amp and speakers at the same time, to ensure compatiability with regards to power?

If you're doing alot of the 16/17/18/21 stuff in social clubs you might like something impressive.....

http://www.class-d.com/Product.aspx?PRO=717

for just £100 more, You'd probably need two amps though (tops and bins) otherwise you'll end up running the system at 2 ohms.

They don't justify anyone's time to explain! I actually found the speakon outputs out of phase on the amp I used (I bought one for school - doh!)

[ross@rds]

Its kool ive found a system

What amp ross, and it takes you over your budget

[ross@rds]

Ive uped my budget after hearing about these , amp Behringer EP1500.

[Danno13]

Ross.. you'd be daft to buy the ep1500.. its 280w at 8ohm. For an extra £25 you could have the ep2500 which is 450w at 8 ohm!

[Tony Scott]

Agreed! ABOUT THE AMP NOT THE DAFT THING! :D

I wonder if you have read some of their blurb. Run into 15" full range first, link parallel into subs= 4ohms. Then feed 12" tops from sub crossover without affecting impedance. Run at 4 ohms, it's the system I would have probably have bought if I had gone into the shop with a little more forethought, and £150 more cash!

Is any one selling secondhand equipment? idealy boxed CD & mixer set.

I just took a look at the spec on these class-d things, the bass bins have a maximum spl of 90db, this is a maximum spl, means that driven at full power (350w) they only create 90db which is next to useless.

Class-D bass bins produce: 90db for 350watts @ 1 mtr
By comparison my bass horns produce: 99dbfor 1watt rms @ 1 mtr

Given that volume doubles with every 3db increase my bass horns are 3 times louder at 1watt than the class-d bins are at 350w.

This would explain why the whole system is only £399.

If I have got my sums wrong please correct me, but I think I'm correct.

[Niteowl]

I have some Class-D Speakers they ar fine good bass response. I imagine the rest of their stuff is fine. I think you may have your sums wrong?

[Niteowl]

Thanks but I'll pass. I keep watching DJ Bids but there never seems to be more than a few items on it.
Required double CD players & DJ mixer 19" in a flight case. To be as second set or back up toto main set. Not fussy about make as long as it is working codition and reasonably priced.:bang: :beer1:

[Tony Scott]

I based my calcs on the max spl of 90db that class-d specify for their CD15 SUB BASS CABS and based on that my sums are right. Can't say for their other speakers coz they don't seem to specify the spl.

The spl relates to how loud a speaker is for a given input and has nothing to do with bass response, I'm sure they give a nice deep bass but with a maximum SPL of 90 db you would have to put an awful lot of power in to get anything out.

The only thing I can think is they may have miss printed it, they do seem quite popular though! :)

i think its there sensitivity 90 d/b 1w 1m typing error i think

Don't think for a minute that you're wrong. I have found that my Class d's need a lot of power putting in for a good response. Yes, more expensive gear would be more efficient, but correspondingly much more expensive. Some of us cut our coats according to our cloth.

Edit note: Didn't spot that it said 350w rather than 1w ! Must get my eyes tested! Other than that my comments stand

I haven't a clue if your right or wrong, as I'm not entirely sure how you work it out, not that I would if I did!

I can't really comment, as I'm pretty sure they arn't the subs we've got.

so....I know nothing! :beer1:

Sorry lads I'm not slagging them off I was just a bit shocked at how low the SPL was, It really is exceptionaly low.

I do get a bit passionate about sound, same as you with lighting Will, so please forgive my Tech-rant!! :D

Good point about cost v efficiency Excalibur. :)

[Tony Scott]

i think its there sensitivity 90 d/b 1w 1m typing error i think

Yeah, must be Gillo.....that's still very low though even for a 1w @1mtr spec, particularly as they are of horn of sorts :)

Not trying to open a whole bag of worms but isn't there some HSE at work law going through about 85dbs in work places Ie pubs function rooms etc.
I am happy with mine although they aren't subs but I have been looking at some off their site. :confused:

The bass output is superb, it's the top which is less wonderful.

Hi lets talk about speakers because there is some absolute rubbish being talked. I have been a profesional cabinet maker for 40 years or more and used to build for martin audio. Firstly the enclosure whats it made of that is chipboard ,mdf, ply, or injection moulded plastic. how is it put together glued, nailed, screwed, stapeled, or biscuit jointed, is it braced ? has it been tuned, is it the right volume, is it long throw, if your using subs and tops are they in phase what is the freqency response are the xover points correct and i could go on. the point im trying to make is that speakers are a sicence in there own ,and the sad fact is the manufactures of a lot of speakers aimed at the mobile market know most end users are pretty clueless hence we have a lot of boxes nailed together with some cheap far eastern driver that you have never heard of and cant get reconed . If your serious about your sound do a little research and ask yourself some of the points i have mentioned. phew! glad i got that of my chest love the forum really TONYTIGER

Have we said something to upset you?:confused: :D

Actually I agree with much of what you say, there really is some crud about as prices are hitting the floor for some stuff. It is unreasonable to expect to get a BMW for the price of a Skoda.

However, speaking to a nice man at a company I respect, I had my suspicions confirmed that some equipment ( which I have some of ) is identical to a more prestigious name, without the big-name badge yet much less money. If you get the badge-engineered stuff well and good, if it's just crap, then tough!

[DJWayne]

Looking at those class D speakers that were posted i have to say they don't inspire confidence just stating the obvious "what would you expect for £400" they don't look that clever.

I thought the old days of DJ's taking in 3 pairs of speakers was gone and that todays professionals have gone for more compact and powerful speakers I know i have.

If it had not been over my budget, I would have got that system. It would have been very flexible in the ways it could be used. However, I got the three way enclosure 215's for much less money, and the better sound. The downsides with these are they are a bit heavy, and if they are not on a stage, lose treble as the puntrs mill round and muffle the top end. However, I since purchased a pair of Class D subs, and a crossover, to utilise my old amps. The bass output is more than adequate, and the sound is very good, with my old Eurosys 3's on top. This is now a very acceptable second rig, and is used as main where space is tight.

[DJWayne]

I suppose everyoone has their own taste when it comes to sound and what they think is good or bad sound. I use expensive speakers becuse i like the sound they give me and the ability to use a small pair of speakers instead of loads of cabinets which is hard work :)

I'd like a pair of 15" , four ohm full range to handle about 2000watts , weighing about 15 kilos, but sadly I can't afford any! Till then Class D and three shredded wheat it is!
