Back Loaded Horn Speaker Build. No Happy Ending (Yet).


By gjm , December 18, in DIY. Is there a specific way to decide or identify a bass driver that would be ideally suited to fitment in a back-loaded horn cabinet? There is so much about speaker design and build I don't understand; I've read 'til I can read no more, but I've not found anything that helps in this respect. Of course, it could be that almost any driver is suitable. I suspect that one of the questions is 'why a BLH? Which I like. AmDismal 8 posts.

December 23, Foal - Yes the soft absorbent bits cut from the inside - there is no bound to the things I will do, lure, capture, kill for this hobby.

We did have the rest for supper so it's not like it was wasted. If you are planning to have something just for mid-bass, I would suggest front loading, rather than back.

When I thought it would be nice to build a power amplifier, I quickly decided I had to become very narrow minded or it would never happen. I know Coco has scratched his head and thought "WTF? I have tried both, and while it was a hopelessly compromised and limited comparison, I preferred what I heard 2A3s.

That's a work in progress, hopefully nearing fruition albeit courtesy of my having cheated a little. Speakers are a similar thing. There's farsands of 'em! So, I would like a two-way maybe a three-way, but only if essential design.

Mid sits in a 'horn' on top of the cabinet. I can't prove or disprove BLH without disassembly, something I'd prefer not to do.

When you say front-loading Something like a TL rather than a horn or folded horn? In effect it's a crude acoustic crossover that achieves this. It's otherwise known when the front of the driver is loaded by a shorter flare as a compound horn. Personally, I'm no longer a fan preferring instead to restrict a driver's range of operation to octaves at most.

Well you can use a 2A3 for the bass, as long as you have high efficiency. That will mean big. You also have to define what you mean by bass - low bass with horns is proper big, but mid-bass is manageable.

Why don't you build something like the Living Voice Olympian? That has a folded front-loaded horn for the mid-bass, which is a big cabinet but not absurd. I don't know the XO frequencies Kevin uses, but you could use something like that for Hz, maybe a bit lower. You then need to decide what to do above that, but there is plenty of choice - and horns would not be too big either about 2' long and under 2' wide.

You could use something like a JBL like I have not set up yet , from to 8k, then a nice tweeter; all you need to do then is come up with a deep bass solution, maybe a REL or other subwoofer?

The aim is something around 30Hz or marginally less, and for a conventional horn to achieve that it'll need to be around 10' feet long. I do like Steve's horns though Early thoughts on this were something like the BKKH. However, that horn is probably a bit big to be domestically acceptable at this stage. And I would prefer to not use a sub if possible - our room doesn't lend itself to positioning one anywhere. Interesting - they use a BLH for the deep bass, direct radiator from that driver for upper bass and mids, and the horn from Hz up.

A 2A3 would struggle, unless you want very low levels. Like Guy I am sceptical of using the front horn combined with the BLH as an acoustic crossover in general - while my Lowthers worked very well indeed, I think that there is a lot of luck to this kind of design. I think if they were your own DIY, you'd never stop tweaking unless you were incredibly lucky. With a kit you might be OK, but the depreciation is a killer if you don't like it.

I alluded to, but didn't make clear, that I'm interested in using a 2A3 or monoblocks for the mid and high, but something different, probably solid state class D? Coco has already pointed out that I'm making bloody hard work for myself this way. Is there a way to use a bass driver no larger than 10", with a horn for the treble and mids?

The only 10" drivers I can find with suitable response are around db; an economic option would be an Eminence at 97db, but they appear to lack the bass extension.

Troels offers details for the " Jenzen-Accu " But no horn. Before anyone asks - the horn is just something I want. It's not something I've concluded is the solution to a problem so yes - I really am going the wrong way about this. The Bugatti Veyron school of design - this is how big it will be and what it will look like, now make it do mph. Build an Avant Garde then? Some kind of powered bass box to do up to ish, then a horn above that to 6k or so , then a tweeter.

It might get a bit beamy from the mid horn, but could work. Your mids and tweeter could be proper sensitive for the 2A3, well into the s. The killer with these is the horn size and crossover freq. A Hz horn, which you would normally cross over at Hz, is about 2' radius and 2' long. They just can't be small. You want to cross over to the horn as low as possible to get maximum horniness, but this means size. Show the Mrs a few different horn designs.

She may like some designs She likes the AG Trio Classicos, although we don't have room for them who does? The Auto Tech site is yet another interesting one. With the Auto-Techs you can build something that looks pretty cool, and get them sprayed in whatever colour you fancy at a car repairer.

Sounds like you're fine for a midrange upwards solution, it's just the bass up to What about an Eminence Alpha 15 in open baffle, like I'm listening to now? It will be a box open at the back about 18" across, 24" high and deep, give or take.

Sensitivity will be lower than the horns, so use a different amp, as you plan. Not ultra-deep, but refreshingly free of overhang. Plus the box would be a perfect support for the mid horns. BLH has huge phase issues. IMHO it's just a matter of pure luck to get it right at your listening point in your room.

Too big I was thinking of something like these. Gordan - there are many mysteries in hifi. Shouldn't take too long to build. You can post now and register later. If you have an account, sign in now to post with your account.

Back loaded horn speakers


Greetings to all music lovers out there. I'm ready to start my first DIY loudspeakers project, it will be a full range back loaded horn, a Fostex design enclosure that is published on their official website, the FEEZ, that uses their FEEsigma full range driver and the TA horn super tweeter. I don't know if it's okay put the official Fostex links of the enclosure plan and drivers here, please let me know Anyway, in fact, It's not me that will build the enclosure, as I don't have the skills and the tools, I will pay for a woodworker that have some experience building loudspeakers, or a woodworker that never built loudspeakers, in any case, I think is important for me to know some general fundamentals about the construction to talk about with the builder. Here's my doubts: It's a must in loudspeakers design, the enclosure be inert, with no resonance at all, is that right? That's why the most recommended materials are MDF or Plywood? Because they have great internal vibration absorbent capabilities? I noticed on the enclosure plan, that are two places that indicates the use of sound absorbents, what is this material? If anyone knows some people that already builded this design, and it's using the loudspeaker with good results, I appreciate very much if you can indicate my thread for they contribute with valuable information, any information about more experienced people is very much appreciated. I think for know it's just this, but I'm sure that will appears another doubts when I debate the subject with the woodworker

Audio Forums. Back-loaded and transmission line? This is my first post and before I have decided the type of DIY speaker to build. My question is whether a back-loaded horn type is the same as a transmission line speaker? I suppose my interest is specifically whether the BL horn can produce the same low frequency as a quarter wave TL? Beemer, Jul 10,

The resurgence of interest in full range speakers has led to a renewed exploration of the rear-loaded horn. This coupled with a whole new generation of more advanced computer-based modeling tools have given designers more power to generate better designs. F rugal-Horn. FH3 been shown to work with a wide variety of drivers. More are being encouraged. With Fostex doing a complete revision of their popular full-ranges, most of the Spawn of Frugel-Horn became obsolete.
