I finally documented a build with some picture's as I usually forget to make any :)

Hope u enjoy:

Ready for cutting:

7 sheets of birchply cut:

Accespannels glued:

Template bit:

 

so how do they sound? 

Ive been trying to make jug for connector plates recently, out of curiosity how did you do yours?

 

 

been using the a collar in the end after various different efforts.

sorry for the hijack

Yes the jig for the miter cuts was a nice idea, actually pretty simple but it works!

The jig for the connectorplate was made using a 1:1 template and a bit with top guide bearing as u can see in the picture.

The handle jig was made in the same way, some jigsaw work and allot of filing and sanding.

But off course you only have to make those templates one's.

They sound very nice, you get the clean and precise kick from the horn part and the low extension from the bassreflex, best of both worlds

Usable in both big and medium sized venue's.

Dust was coming from the ceiling, things started to shake and you could really feel the kick in your stomach, allways a good sign hehe

The bass-reflex tops are tony wilkes design, double bms 12n620 and 4544 cd's on a cellestion horn.

First I was worried they would have problems keeping up with the 4 mhb-46 but it was no problem whatsoever, they kept sounding crystal clear with no hint of nasty resonance of any kind

I actually think they would be able to cope with 3 mhb-46 per side driven with the right amp, amazing drivers

The mhb-46 were powered by 2 bridged mpx-1200 amps, and they ate it all up and kept asking for more, what's next a crest pro 9001?

Two were loaded with rcf lf18n401 that I had from a previous project and the other two with rcf lf18g401. 

Very similar driver's but to my ear the n401 sounds a bit more ''agressive'' there was certainly not allot if anything between them in terms of power handling and output.

Seeing the neo's are big money now, the g401 is a amazing driver for the money.

Yes the racks weigh a ton, but oooh those amps sound sooo nice and worth the hassle in my opinion, and 60kg for a 2 amp amprack is doable with 2 persons, saves me a trip to the gym

Im using 12n620 too, they seem too like a lot of power a sound great.

Thanks for the template help.

 

   You got a nice review on this!Any chance of using it on a real gig specially on live band?I really want to build this and use it mostly on live bands,i like the design,simple build.Thanks.

are they heavy? they look fairly manageable?

Have you per chance heard the in comparison with the MPB-46? im looking to build some form of hybrid short horn and these look superb but also quite complicate to build.

 

Saving money to build my MHB's is such a tedious process, I cant wait haha

Pretty deep because of the BR and kick really good with the short horn.

Pretty easy to run as high as 130Hz 24dB/oct LR, sounded pretty good and gave the a proper beating with a proline 3000.

I'm using the RCF LF18G401:s and i'm really happy with them, would maybe give me som dB extra with the neo variant.

But it's hard to motivate the cost, so this will work for me.

Gonna build som more in a while I think, want more bass!

It's never enough is it? 

Good luck with the build.

Have to say the Jerronimos built was the main inspiration for me.

And since I speak and read french pretty good, it was good reading over att the freeplans forum.

But I think google translate will do a descent job there.

There is even som measurements of the cabs there.

Gonna do some myself in a couple of weeks, during my holiday.

Maybe just maybe there is a picturepost in there somewhere, we'll see.

 

What mid tops are you running? I'm going to be using the MT130 I think. It's just a hobby for me, I'd probably do the odd club night but mostly just small, private, non profit parties for fun... For the time being anyway

 

Have you used your MHB's outside at all?

But half the amps needed.

Besides they will fit just nicely on my trailer with the midtops between the subs, and the amprack and cables in the trunk of the car.

 

Top system is.

120 to 300hz a regular basreflex box by my own design that is mountable on a polestands.

Tuned to around 50Hz to be able to be used standalone also, used PD 12SB30 driver.

300 to around 3000hz is a Turbomid horn with B&C 10MD26 driver sounds really good in that configuration.

 

Upper tops have rubber feet that goes into recessed holes in the "kicks"

 

Will do some outdoor testing of the system in the coming weekend, good thing to live in the country with almost nobody around.

Have a few friends coming over

One of wich Anders Martinsson, the designera behind the THAM series.

He doesn't live that far from me.

Think he will bring some speakers for testing, we will probably do some measuring also.

 

Will get back with the results.

 

Don't I know it, damn those things are bulky.

But I got help with the lifting, so that's fine.

 

Will get back with the results, will probably try some stacking options also.

We'll see what the time alows for.

 

Sounds like you got a nice system going on there Slaith.

 

I will post pictures etc when I get round to doing mine.

I did som proper measuring after you left

Tried the subs in different configurations, and a little EQ:ing also.

Just have to sort the images, and make it into a proper post.

Will post the pics and analysis in a different thread, don't want to contaminate Jerronimos. 

Anders I did som more testdriving after you left, played Greyhound by Swedesh house mafia.

Turned eveything up until my Proline 3000 was almost clipping, my guess is around 1000W per driver.

Then it really came to life, 124dBC at our listening position.

That was about 7 meters from the spekers I would guess, did som measuring about 50 meters back and I still had around 110dBC of sub.

I actually lost my breath when I wanted to check how much the driver was moving, phew!!

Gonna go that way next time you get here!!! You'll see.

BTW it was a privilige to listen to the THAM10.

So thank you for that!

Will post the same analysis in the upcoming thread along with som EQ tips, just to get the MHB:s even better.

Great stuff

eq , stacking, xover tips?

How modern house music, trap and moombhaton music is sound in stacks of 4?

How is it performing Indoor and outdoor?

Though I have to admit I havent gotten around to doing them yet.

It includes making the port a bit narrower but extend it all the way to the sides, I made a lid on the top for the driver.

Making a much larger flare both at the front and back of the port, at least 30mm or more.

Then extend the port as much at you can until you just can pass the driver for mounting.

I did sims in hornresp and I think the final length is about 350mm or something.

The result is that the port response is much wider and deeper, now it's at narrow peak.

It doesn't matter that it's not the same amplitude, it will give more depth and a better response.

When I finally get around to it, I will do A-B measurements of course.

I run my boxes with the recommended HP crossover of 35Hz 24dB/oct LR I think

And 120 Hz 24dB/oct LR, which works great, it's a good allround box for me.

I run just two, and could actually use two more to get a little more SPL.

The drivers are RCF 18G401, rated at 900rms.

I drive them with a Proline 3000 bridged and the boxes in parallell, up until clipping.

So I give them 1500W each and they just take it, smells of voice coil laquer sometimes but it's all good. 

For me it's a great allround box for bigger gigs and partys.

My 2 cents.
