Full Version: Class D Speaker. Anyone used them?
Blue Room technical forum > Technical > Sound

Hi all, any one have any experience of Class D speakers, just looking on eBay and came across these monitors that are only £140 a pair delivered.

I could do with some cheap ones for a church band (that are actually very loud) but I'd rather they didn't fall apart within a couple of days.

Cheers for your help

PS this is their website Class-D

For a firm that has a somewhat misleading name (seeing that Class D would evoke thoughts of efficient switching amplifiers in many people's minds) these units appear rather underwhelming.

The usual advice applies:

"You get what you pay for"

"Caveat Emptor"

In this case, the concept of "costly middle men" has largely been superseded by "online retailers willing to slit the throat of the competition to make a sale".

As our American friends might say, "go figure" ;-)

Don't know about the product, but I found the advert mildly amusing. In particular, the bit that said

(our 70-quid-each monitors are..) considered by us and professional uses to be as good if not superior to all other makes.
(so watch this space for news of D&B, Nexo and the rest going out of business.... )

It is a PASSIVE not an active unit. That means you will require to drive it off some sort of amplification. Many modern amps have the facility on them.
So don't be using one of those old-fashioned amplifiers that don't have the facility to amplify....

As I said above, I'm not commenting on the units. I'm just having a bit of a giggle at the advert....

Is there not some sort of legislation against having misleading trading names? Or did I dream that one up? hmmm

Also - don't those units look a bit like a Behringer Wedge?

Hamsters in their wheels all over the world will be breathing a collective sigh of relief! laugh.gif

Actually, I have a couple of amps here that don't amplify!

Note to self....time to spend a day or two at the "bench".

You will get class D sound. Maybe if you get a good deal on a super old system that back in the days was used for professional use you might get a closer answer about if it sound's good, but cheap speakers use cheap components and with cheap technology. Would you expect great sound out of it?

The word "bargepole" comes to mind!
beware
I use them. They're OK, but you do get what you pay for. They have no specs available, and the bass bins I own have been rated at anywhere between 350w and 500w rms depending upon where you look.

The "350w" tops I have (running off a 360w amp) can sound quieter than my custom built wedges (Eminence beta 12" 150w) running at 105w... I have no idea what the SPLs are on any of these speakers, but I can only assume the Class D are not too efficient.

The bin+top combination, run at 1600w (460 to each bin, 360 to the tops) sounds quite clear, but is no comparable to the professional makes, which go deeper and louder.

biggrin.gif I'm sure that no distortion it's included on that measure.

I run class D speakers. I'm no sound tech guy or anything. But for a five piece band we use 2 pairs of tops and a pair of 15inch bins totaling 1700rms. If u put them through an rta it pulls out a few floors. but considering I only pair £450 for the whole lots I think they fill a gap in the market. For people who arnt too fussed about having expensive kit. They certainly pitch above some of the crap thats on Ebay, £180 for a pair of 300watt PEAK bins is what I call crap. Good guys down there, and fantastic after sales service. Been running them for a year now.

Let me know how good they are if you do get the monitors, because we're having a few problems with some wharfdales.

Does this mean

a) If one were to investigate these loudspeakers with a real time analyser, the frequency response is far from flat,

or,

b) The combination of loudspeakers and RTA is capable of causing serious structural damage to properties?

Just curious ;-)

Now I'm curious, are u looking for something to cause damage to properties???

I meant the response isnt very flat, but not having anything to compare its analysis with I dont know it all speakers have their poor frequencys. And on the same note, I have only ever used the rta in two different venues. Each one giving me different readings.

p.s. I'm using a recently bought Behringer DEQ2496 to measure and adjust.

No - just a little tongue in cheek dig at your spelling ;-)

Which might well be expected. If you search this site for 'RTA' and 'Smaart' you should find some good material on loudspeaker measurement.

I think you meant "flaws", but it has taken me a while to work out what you were on about.

Just to let you know guys,

It has been relisted on Ebay:

Try here

He/She still wants £125 for them though.
tekhieboy
They will keep relisten them, they guys selling them are the manufacures, they use eBay as their shop. The price will probably either stay the same or even go up in time.

Probably won't buy them as I can't get to test them, so it's a can of worms that I don't wanna play with.

Some previous discussion here. I stand by what I said in that thread.

I will have to jump in here and state that I have worked with the guy's from class-d for a long time, the products are far better than the price would suggest.

I there was a similar reaction on the other forum mentioned but as more and more people get them or hear them the feeling is changing.

Both myself and class-d offer a money back guarantee on the speakers so to say that you would not buy without hearing them is not an argument in my book.
What better way to audition a pair of speakers than in your own environment? We even pay for the courier to come and collect them if you don't want them.

In all the pairs I have supplied I have only ever had one customer return them and that was because his wife found out that he had bought yet her pair of speakers.

Most of the slating about class-d comes from people who have not tried them and is based on price alone.

Ok they are not the best speakers in the world but they do punch way above their weight.

And there is a good reason behind the name as well.
