Subject: Martin Audio H3
Date Posted: 30 December 2019 at 1:07pm
Hi guys, I would like to create 4 speakers for outdoor use. My choice fell between the RCF 4PRO 6001-A and Martin Audio H3 + (H3 +, H3T +, H3H +). I searched the web a lot, I didn't find any plan for these speakers, I saw that there is a copy made by Tpa Pro Audio (TX-3). Which one do you prefer among those mentioned above? Could I do an H3H + and if necessary use it in array mode? Do you have any plans?Thumbs Up

You will not get any plans for Martin Audio H3 either on here or any other site as it is subject to Martins own copyright and integrity. The copies that you mention are illegal Chinese copies that are poorly made and contain crap cheap Chinese drivers so no point in buying them even if you could.
You are based in Italy so the obvious choice for you would be products from RCF or other Italian manufacturers.

So why are there many other Martin Audio projects, such as the WSX? What do you recommend between Martin Audio H3 + and RCF 4PRO 6001-A?Wacko

It's much easier to measure and copy a speaker just made from sheets of wood than one with high frequency horns which are moulded or fibreglass or whatever.

Doesn't make it right though...

Buy the TPA boxes mate.

I could find the fiber trumpets, the problem is finding the H3 designs, everything is silent on the web. Would you be interested in contacting TPA to buy the project drawings?

you wont find the H3 plans, its a commercial product. Should someone make a plan, the MA legal team will be chasing them. Should you build some, the MA legal team will be chasing you.

Its just not worth it.

Anyway, the H3 really isn't that special a box. Its some reflex mids, with a mid-hi horn fiberglass horn (aka: trumpet). There are loads of 8+1" horns available on the market already, and it will take 10minutes to design a reflex box to go with it. No dark magic going on, its just some relatively efficient drivers in a tuned box - even the processing is nothing you wouldn't work out with your ears.

If going for such a cab, why not built something like the PM90/60 (Peter Morris DIY).
From 100Hz and up it probably performs better (with correct components and processing) then both the RCF and Martin audio. 

It's also much lighter.

I had never heard of Peter Morris, I did a search on the web and I did not find a personal site where to find the design plans. I searched the forum and found several products, but not something done and finished. How difficult do you think the production of these boxes would be? We read that the configuration is very difficult to make them sound good, even if the yield is statospheric (how is it possible with only 2x12 "to make 100-20K Hz?). There are many plans of RCF 4PRO, specific components to use and the configurations are ready

I have 4 x TPA TX-3s (their H3 copy). For the price I paid for them, they're good value - I've had 5 years of trouble free usage out of them and they sound fine too.

I found their customer service to be pretty average, though when I paid the same price as a single Mackie SRM450 for each (shipping included), I can live with that.

My $0.02, cheers.

Well cloning a clone could almost be an ethical thingLOL
I looked at tpa site, they even literally copy Martin marketing terms like unique phase ball for the phase plug.

Jokes aside, a big part of the sound of this speakers in the original form are crossovers and processing, so even with plans getting them to sound tight would require work and knowledge, which you don't seem to have.
Intellettuale theft issues apart, you'd Better look on the second hand market. Look for italian brands like rcf, outline, montarbo

I really love the design of the H3 that goes well with my musical genre. The alternative would have been RCF 4PRO 6001. But I have never heard either play, so I don't know the difference. I use the WSX as a subwoofer, so I thought about the H3. If you can't find the TPA plans, do you know any other boxes with similar designs where the plans are published?

It's still not the design I want, I'm looking for something from the club, as well as Funktion one

if you think you can produce a copy of a commercial cabinet then go for it - it's not illegal to do so for your own use. but I don't think anyone here is going to spend their time helping you do so.

Okay, but going back to the starting speech. What would you recommend between RCF 4PRO 6001 and Martin Audio H3? I am afraid that the opening of the RCF 80 ° x 60 ° is too wide and dispersive

The H3 is still technically a current product (just called THV with a nicer grille).

Why the obsession with cloning cabs?

Do some reading and make some of the DIY designs that fit your needs (dispersion, ability to use in multiples etc) or just buy second hand.

You don’t want multiple H3s a side. (In the average room).

You're right, it has become almost like an obsession to recreate that design and those characteristics of that speaker. The charm of the hybrid, which is reminiscent of the WSX design. The speakers would be paired with the WSX

Have a look for some W8’s if you’re going to go more than 1 a side on some WSX’s.

The W8 are not bad at all, but in Italy it is not found on second hand. I would prefer to build them, there is no mention of W8 anywhere on the web. As for the H3 / H3 + I already have how to configure the cuts, earnings etc.

If you searched correctly you would have found tons of information.

Including which drivers can be used, and also their correct processing. Nowhere is said that it is very hard to get them sounding right. If you want the best of the cab it will become more difficult because you need the correct FIR processing. 


PS: it doesn't only have two 12" drivers. The whole cab is mainly designed around the coax HF driver. You can use a 4" VC HF driver laike the RCF ND950 but you don't get the same result. If you go for the PM60 you can use two boxes aside (which would be loud).

Yes, the WSX are also copies. There are many design plans for the WSX. I had the boxes made by a specialized company that made many of them, the speakers are RCF 18LP300 that fit perfectly

here you go, this is a great start to reverse engineer. You need to get a 15" 10" & 1" driver in there, and make it weigh 77.5kg. Should be easy to do!

Whilst it won't get you the H3, but here's a link to find the Peter Morris designs... either the 60 or 90 degree.

Also, why not have a search for the X-TRO?

yeah i don't understand this thread at all.

if you're interested in building speakers.. embrace the DIY scene. you've been given plans and suggestions for some great diy projects.

If you find someone with cad plans for the pm90 I'd like them!

I shipped 4 x W8C to the south of Spain for less than £300 in the summer.
Making the comment (no W8 available used in Italy) totally irrelevant. 

The amount of money you will waste on trying to build / copy. You will buy used boxes and have change.

Lorenzo:

You won't get plans from anyone here, for a speaker that is still available from the original manufacturer. For one thing it's against the ethics of the forum, and for another, the manufacturers are likely to sue anyone who publishes plans online for current products.

If you have an original H3, of course there's nothing to stop you from reverse-engineering it and making  copies for your own use. In that case you wiill only get into trouble if you try selling them as the real thing or making batches for sale.

Old products that are no longer made or sold by the original manufacturers are fair game for builders and a lot of plans are available and in the public domain. But not current products. We'd all like to see the few remaining high-quality speaker manufacturers stay in business for as long as possible...

Think he might have got that... his latest request was for the peter morris pm60, which is a free plan.
