Or is the answer very simple, in terms that some people just like tweeters with metal character? I have not heard the Supravox, but it has the usual breakup above the audio band, even a bit stronger than other metal domes, CSD from 4kHz up is not slo...

A few years ago playing with my favorite Vitavox S2 driver I was asking myself how it might sound if instead of the Alnico magnet the electromagnets would be used. As many other driver of the period the Vitavox did not utilized the only one magnet ty...

[quote user="kodomo"]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![/quote]I think that Group Delay an...

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...

Hi Kodomo-You have made an ambitious undertaking. Congratulations to a brave decision.Can you please elaborate a little on your TAD implementation. I have used one on each side ,in 3 cuft sealed cabinets, first order from 60 to 150Hz, blending gent...

I understand your recommendation and agree. I need to have upper bass and MF and than see how to merge fundamental channel in between.So, I better postpone experiments with compression drivers and only compare 12" Supravox in two horns: 42Hz 2m long ...

[quote user="mats"]My humble guess is that the titanium diaphragm won't ever give you the feeling you seek.JBL 2482 with its phenolic diaphragm may not be the quickest or most detailed, but has a truly wonderful tone that I never tire of.[/quote]I ha...

[quote user="Murataltuev"]Here is frequency response without horn:Here is in my 46Hz horn (green is GOTO, blue is Supravox):[/quote]Perhaps that GOTO hole centred on about 225Hz is to do with using the incorrect throat in the horn? First thing I wou...

Forgot to elaborate the Quad system.It is actually a tri-amp Quad system, below 100Hz is the Supravox 15in Field coil in open baffle, then it's a Stacked Quad ,and about 5Khz there were 5 RTR ESL cell. I did try the 6C33C amp in a single pair Quad by...

[quote user="anthony"]It is a compression driver with an 8" cone. If you want authority at 300Hz you will need diaphragm area. The Fane Studio 8M that Romy and plenty of others use for 100Hz up to 1kHz is an 8" cone driver on a 4" throat with a clo...

existing horn and it is obvious for me that I need different horn for GOTO.

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 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...

So, with this horn I got the sound I was dreaming for!Currently system consists of 4 channels:1. RAAL Lazy Ribbon (14k+)2. JBL 2453 in 550Hz LeCleach (1200 - 14k)3. JBL 2490 in first part of own JBL horn (300-1200)4. 12" Supravox in 42Hz 2m long horn...

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...

[quote user="kodomo"]I have also designed my bass horn to operate between 160hz and 600hz and it will use a supravox 285-2000. It is a 110hz cutoff tractrix horn. However I found out that, there is a modified version of this driver that suits my purp...

It is a good question that I also asked when I saw this speaker. Afterall, everything being equal using the same materials for the drivers is more optimal from a coloration standpoint. My guess is cost. They already had splurged for...

Folks,It is really amusing. Here I am busy myself for a while and am not looking and suddenly Roman talks about Mini Monitors and secondar phonostages.It is even funnier if you realise taht I am on a similar kick right now, simply because I am workin...

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...

Which values are you after? If its the crossover points, here they are, they ay be indicative for you;dual Tad1601b's in 298lt br boxes - open on bottom to 120 Hz, in a range 90 to 150 Hz ~12 dB (three different settings can be chosen, according to r...

I am currently planning high-WAF speakers for my sister which have to stand in the corners on the floor. Asking for small corner horns I was told the EV Baronet could be a solution. Simulating it with roughly estimated dimensions I found that the FR ...

[quote user="Jorge"]I tend to like drivers with plastic suspension. Radian makes retrofit diaphragms for JBL with plastic suspension, maybe they will help you achieve the tone you are looking for.
Extensions are easy to machine out of aluminum, eve...

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 ...

Hi Romy,You wrote:"They tunes for 115Hz and pushed in room down to ~95Hz one channel and 150Hz another."So do your horns have 115Hz flare frequency? (and have the rear chamber tuned for 115Hz as well)From the pictures the horns lo...

I see, this tri-way Quad system for sure shall be much different from regular Quas. I kind of even understand why you stay with open baffle bas to support the system’s bass. For sure it will not Bruckner-style pressurize a room as non-dipole bass wou...

[quote user="Gregm"] It's better than a Marten Supreme because the mid is cut off @500Hz whereas Marten cuts it off at 1,3kHz "where the ear is at its most sensitive". Note: they must be referring to latest technology ears -- not the tradi...

I don't know why the Berning topic gets everyone so worked up. No need for another ZOTL screaming contest. Is this not a hobby where we explore many solutions? It is a difficult subject technically. I for sure can not speak about th...

Hi Greg,linkSearch the site and you'll find that Ulf has created a upper bass horn using the aforementioned TAD 1201's.I also own a pair still in boxes waiting for the weather to warm up enough for me to start some enclosures and horns for.My origina...
