Yes, the topic is really interesting, at least to me. There is one thing
for sure – the man who starts the development of his acoustic system with a blank
sheet of paper, must have a lot of experience in arranging different channels
in terms of ps...

I've had a long-time desire to replace my Edgar 80hz midbass shells with a better performing solution. My Edgarhorns arrived in 2005, and I made incremental improvements over the years until now they have little in common with the original Edgarhorn...

[quote user="Romy the Cat"] There is one more subject that most of the people are missing. I personally located horns not in-the-walls as most of people do but my horns are extended well into my room. I feel that this sounds way deferent but this is ...

I kind of got stuck in selecting an upper midrange driver, above 2kHz. If a driver is going to screech in your ears it is going to be in these frequencies. I was never really satisfied with the range of 1" compression drivers I tried. That is wha...

Putting together a speaker system that ticks all your boxes is a lot like doing anything else well: it is fine to experiment in order to find your range and learn your options but once you choose a path you must stick to it. Chopping and changing i...

[quote user="Wojtek"] Roman, could you (or enybody ) elaborate a little bit on JBL L8 and its application ? Not so much sensible info on the net besides that its a fullrange usefull in 40Hz-8kHz. [/quote]I do not know, how can I elaborate if I never ...

actually this is not so much about horn loading ribbons as it is about curving them, but also horn loading. look at this horn: http://www.pioneerelectronics.com/pio/pe/images/portal/cit_3442/35960TH-4003_s.jpgnow imagine a ribbon of approximately sam...

[quote user="Romy the Cat"]...though considering the scope of his customers he might not stick the MF drivers into the horn and those Morons would hardly notice anything. Most likely this specific Moron got the speakers second hand... [/quote]H...

Hello Dan,Love how you pass that cable through the port, I used to do that too...long time ago.Why are you crossing your 250hz horn all the way up to 1 khz?The 2445 should be able to go much lower. Have you measured the response you are getting from...

Hello,I just logged myself in so first of all: Hi Everybody ;)Few days ago I aquired a pair of very interesting 3way horn speakers which seem, as I imagine, to ba an ambitious DIY project from the past. These are basically the Altec Vott A7 replicas ...

truth to be told, i'm so far from building a horn for S3 that the plans may change. the drivers actually haven't left a previous owner yet which makes me a bit nervous. but i understand you presume a short opening horn like expo would allow a more me...

[quote user="nl"] Within that horn-loaded range, the 210/515 type combo does reasonably well, and produces rather more inspirational midbass than most direct-radiator type strategies. There is a reason why these designs persisted for roughly forty ye...

For those seeking some decent compression drivers that don`t cost fortune, I can suggest to try the Eighteen Sound ND1460A compression driver. It has aluminum dome and polyester suspension and 1,4 inch exit throat. Does it sound like S2 ? Probably no...

Hello Romy!Cessaro had severe resonance problems in their room, so I didn´t stay long here. What I noticed in the short time (maybe too short for a qualified judgement) was no stabiltiy broblems but less musical than the 300B last year. Hard to descr...

There might be 'rule of thumb' here, but let me explain a bit better with some specifics.I'll have a Radian CD in a 425hz horn playing 800hz up to where it starts to roll off naturally at 6db at, say, 10K. And a similar Radian taking over from there ...

Romy, thank you for your thoughts. First off, my further thought on the system and specifically the implementation of the high freq section: Yes, the time alignment would be a challenge but possible. This is the main compromise, in my view but the le...

I was there and heard it a while and then came back the next day to see if what I heard was true... it was.I talked with Allen Sides who was there showing his speakers and having a good time. It is a 3 way speaker, It has a 1" JBL compression driver...

This is a good example of a CNC horn. This is the Carfrae I was talking about. MDF Upperbass horns are made in sort of the same way, but you do have to cut the angles on the Lathe. (or leave the steps like a The thing is it is not really tridimensi...

Hi i am a new forum member and recently i built some speakers using Altec model 19 components 416-8b & 802 G. I built some 7.5 cu ft cabinets with two 4" diameter 5" deep ports this is the optimum cabinet size for the 416 i ditched the 811 horns ...

"Sadurni Acoustics' Staccato 4-way hornspeaker exploits MDF horns with up to 3" wall thickness. The 92cm lower midrange horn which loads a cone driver can "achieve 100Hz in-room". The actual 'turbine-horn' midrange driver is a compression sort. "The ...

"the SG-570BL with S-150 horn mid-low isn't good between 100 or 150 (the horn name;-))"Why will it expect to be good at that range?? The S-150 horn has cutoff frequency of 150Hz. The suggested crossover point is 200Hz from GOTO.There is no doubt th...

Too late now for points, but just the other day I tried to imagine your plan. and I was pretty close.Actually, it is a bit like what I have going now; 15" Eminence bass guitarr woofers in a sealed 3 cu ft cabinet,Oris 150 with 8" B&C midrange dr...

Ok, I blamed the tweeters and MF drivers now the turn of the MF horns. The Mid Frequency Horns (I’ll them “MFH” from now and on) are the stinky like pieces of horn installations, and if they are not done correct then they screw up anything big time T...

Hi Guys,An idea I've had for damping thinner horns in a more or less aesthetically pleasing manner is to house the horn in a Sonotube rigid cardboard cylindrical concrete former, and then apply the desired damping material inside the Sonotube.&n...

We should define some borders here; LF, when you have an UBH, should be from around 100 hz down to 30 hz, where the last fundamental tone of an instrument is played. ULF should be under 25-20hz.I would say that a driver playing 25-30 hz should...

[quote user="skushino"]Have you considered the opportunity of raising your upper bass HP crossover? How high do you plan to use your mid bass horns? If your mid bass is comfortable playing up to 280hz (or whatever the right freq is), you can use yo...
