Of course i used the 515-G. this famous speaker suited very well to our bass horn...as any other bass horn ! the only problem with the 515-G was a upper end a bit...noisy with our 6db crossover.When we started with Cyrille-audio a project of a 15" fo...

Hi romy, mine are the 515-G drivers. I will be x-ing over at 600hz to Vitavox S2's (2nd order, yipes!). The S2s are in 320hz LeCleach horns. I was kind of hoping for just a general reply like when you guys look at a pictu...

Can I have some opinions on a potential mid-bass driver for my Altec 515s, as pictured in the attachement? What are the obvious or potential problems I should address?see attached photo: 120 Hz - @800 Hz.For the Altec 515 such a horn should be ...

Interesting experience - thanks for sharing.Just yesterday I posted about this topic:http://goodsoundclub.com/Forums/ShowPost.aspx?postID=13892#13892I will first use a 6dB/octave crossover, but may need to go to a higher order slope instead. I'm cro...

Rony, I think your wish to have mid-bass horn with 515G is a bit faulty. A mid-bass horn for 515G shall be 50-600 Hz. Let me to explain. T...

[quote user="RonyWeissman"] It will drive either my Tannoy Gold's full-range, or my 3-way system (Altec 515/Vitavox S2/EV T-350 or JBL 2450). I could also use it just to drive the Altec 515 and use my current 300B to drive the MF/HF of my...

In the linked there above “Barn Conversion - James' Project” I have expressed my attitude toward low frequency bass. I certainly not “against” bass horn it but have “concerns”. The “open bottom” concept that I invented for myself is always make me to...

Marc Henry-In the 6moons write-up, you mentioned the Altec 515 re-issue not being satisfactory for your purposes on the Grande Castine horn. I presume the specific 515 variant you used was the 'g' type (designed for horn loading) rather than 515'b' ...

Klaus,
The 515-8GPH were in same scale as the 515G with slightly above 35Hz resonance frequency and 103 sensitivity - a very good candidate for 60Hz horn. The 10” throat? No bolls to go for 9”, how about 8”? I’m just kidding. The throat ...

[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...

hi jezzie!i was planning to to make most of the fibers 90° to the axis of the horn, have some time to decide(but not too much, the 515´s arrived at vienna-airport:-)what to you think of using biaxial inlays(fabric visible, then -45°/+45° and the...

Rony,
I am not exactly understand what you are trying to do and what kind of cabinet are you trying to attach in the back of that horn. Perhaps I misread you. There are two types of Altecs 515: the G-like and B-like – they are very different type o...

Sakuma's idiosyncratic and esoteric way of thinking (he believes for example that tubes have a "soul") is not to everyone's liking. He is projecting his mind into a sort of tone control. At least for him this tone control brings him nearer to th...

Skushino, Thanks for pointing it out. Unfortunately with all my desire to understand what CH Audio did turn to fiasco and I absolutely do not understand this LF section. Is it a duplex of 515 drivers with one loaded in this front shallow front horn a...

I had quite a number emails from different people who picked 515G or AK15X drivers and would like to build a midbass horn from 60-80Hz to ~500Hz. I played a lot with different 515 (B, E, D, A) and with different AK15X but I never went for the right h...

N-set, a friend of mine built an amp with this monstrous USSR tube. It has 3 stages and the GU81M is driven by 6C33C.Within context of driving mid or high sensitivity bass drivers, this is all you need. In comparison, his previous SET with 6C33C soun...

Well, the Vitavox is also a "paper driver" that has needs like the Tannoy (unless it is the "horn version"...), meaning the size and nature of the enclosure will affect the Vitavox sound, as well. I always thought the Altec 515 Bs were OK up to 500 H...
