I would like to hear one of your offers in my system. As someone who has an interest in recording, classical music and piano in particular, I would be happy to try out one. Albeniz performance sounds good, kind of exciting and fresh, definitely a you...

The reticulated foam makes a difference and that is for sure. However it does lower the output. From about 1db up to 2.5db! depending on the amount you put inside your horns. Is it transparent? It is not, as it creates and audible difference even if ...

I have found 30ppi renticulated foam in an online aquarium shop and ordered it. It's specs is the same with what Geddes used as plugs in his horns. I will try that on my cf1400hz le cleach with varying depth through layering. First just a thin layer ...

You are right Romy. When I toe them in a little more, that curve flattens. If I toe in and also sit about 10cm's higher, it is both flat and more extended...These will be very important as I will be designing the final stand this winter. I am so happ...

Maybe, some people would be interested in what I am doing with my system. I have been continuously listening and sparsely making changes and letting them sink in. For now, I feel more settled and think the biggest obstacle for me in reaching the ...

I dont think a standart klipschorn would satisfy the cat. I had one, then I heavily modified it and in the end I built my full scale horn system. I still keep that modded khorn system as a second system.If I may suggest, if you use klipschorn, you ca...

It goes quite flat to 20hz with the tapped horn. 20hz to 60hz with the tapped. It has 18db/octave Linkwitz-Riley, and then to dual Tad1601b, where you see the rising of the response around 74hz. I have tamed these bump some, but it needs a little mor...

Yes, when I move the drivers or for that matter if I move my listening position, I realign.What I hear and measure about the drivers relative distances to each other is this. When I first set up the drivers, one horn ended and the next one started, t...

Hello AnthonyDo not worry too much about how high the system ends up or how high the highest horn is positioned. If you are far enough (I am 470cm away from my drivers) and align them properly, the sound is right in front of you. Actually my system i...

Yes, the crossover looks fancy :) More than that it does the job. The vacuum caps are only for the tweeter and the upper-mid beryllium. Still they are bridged with micas as they wont do much alone. Adding vacuum caps smoothens the transitions and sou...

I have my passive crossovers arrived. They are built by hornFabrik. Everything is up to the spec I asked for and I really like their build quality. As of yesterday, I have now a more promising sound towards what I have aimed for. They are first order...

Great project! I have a similar project going on. Your frame ideas are looking beautiful, however I decided to take a more utilitarian road. I can adjust all my channels in horizontal or vertical axis. I am finishing my crossovers as of these days, a...

I have been working on my system. I post sparse as I need to listen a lot before doing any changes or decide on anything.I have changed the 1000hz JMLC horn to a 1400hz JMLC horn and the results are better. I have better integration with the Fostex t...
|
|
Yes, I do believe your exact crossover points would be irrelevant as well. I just wanted to know the span of your horns and drivers. I especially wondered about your fundamentals channel. You said it was narrow but what is narrow for you. Mine covers...

While I am waiting for the attenuators I worked on the frame and changed it to a metal frame.It is sturdy and height of the channels can be adjusted in both axis.Romy, may I learn what your crossover points for your channels?My midrange channel is be...

I have tried a second filter on the Supravox as per your suggestion. Very interesting, it really has audible effect on the sound even if it is small when I put the filter around 40hz. I will try on 60hz and 80hz and keep on listening. It will take ti...

It is interesting to see Richard here appearing and answering general inquiries so fast whereas he hasn't even replied my last email over a month nor send my battery pack of the unit for the last 8 months! I have half of your product and still nothin...

The bass enclosure and that door and windows are the things that I haven't decided on yet! I am the owner and the builder of the house and I can do whatever I like with it. Actually that door and windows are not there, it is different now. There is a...

thank you for sharing your concerns.The LF module I was building was like yours with drivers from scanspeak. However both the dealer was not professional and the the drivers had a certain sound to them (too much character) so I ditched that solution....
|

I have been quietly listening and working on my new system. The upperbass horn can be crossed lower than I anticipated, which is great news for me. I was going to have the crossover point of 160hz, but I can easily do 120hz :) The dual tad's will be ...

There has been some changes, so here is an update;38hz - 160hz - TAD 1601b (2 on each side) - Ported cabinets160hz - 600hz - Supravox 285-2000 Hornfabrik edition - cf110hz round tractrix horn600hz - 4800hz - Radian 850pb 2" cd - cf200hz round tractri...

Hi Mats,I am not using 4 on each side. I will be using two on each side. Until now I always liked sealed enclosures. However Tad drivers are more suited to ported configurations. If you do not push them to go too low and have a reasonable fs point, t...

Hi Murataltuev,I have two horn based systems but the system that is similar to yours or Romy's is the one I am currently building. The drivers and horns are as follows.38hz - 160hz - Tad 1601b - Bass Array (4)160hz - 600hz - Supravox 285-2000 hornfab...

I don't think you can align the tapped horn. My tapped horn has a total length around 5 metres. To time align that with my other drivers, its got to be around 5 metres closer than others. The only other solution is delaying the rest of the channels.....
|
|
I am crossing around 160hz, which is half octave above my horns limit as it is a 110hz tractrix horn. The horn is 1 metere in diameter in its mouth (this is dictated by the cf and the tractrix curve). Anyway, here is my group delay....
|
|
Here is my response for the Supravox 285-2000 in 110cf tractrix. I designed a sealed chamber and with the qtc 0.707 it is tuned to 160hz. However I hope the modified version will be even better!...
|
|
No, the drivers are the same brand but a different model than yours. They are not 10" but 12", it was a typo I made.They are 30w/4558T00. I guess they have lower fs (17hz) then your drivers. 3 of them in serial makes them 8ohms. I am in the lookout f...

I am using sealed bass arrays of 3 per side. I have six 10" scanspeak woofers in total. I aim to operate them from 38hz to 160hz with qtc 0.707I also have a tapped horn that I am using with my current horn system. It is 244cm's high and 125kg's compl...
