Romy's comments in blue :"...Interesting, as all my drivers, the AK151 and K15/40 are high impedance (15R-16R, DCR around 12R). I do not see a lot of difference between AK151 and K15/40..."Apart from the color the baskets were painted (silver Hammeri...

What I like: The fact that they are doing this. The upper part of these speakers is truly beautiful, both in composition and in workmanship, which is on the level of fine jewelry. Sonic attributes aside, visually that Pinocchio tweeter horn i...

[quote user="jessie.dazzle"]The thraot size will be 7 inches. [/quote]
Wow, THAT IS BOLD!!!! The 45Hz how from 7” throat – that is very-very cool and very positively-obnoxious.

Oops,
I'll send the images again once back at work on Monday.
The thraot size will be 7 inches.
Yes I have thought about paying someone else to do the work, but that sort of skilled labor is super expensive around here.
And... Yesterday ...

jd, I cannot see any of PDF files, probably my current networks kills them.
I do not know the AK150 drivers. I know AK157, AK151 and K15/40. If they have significantly lower free-air resonance, at 30-35Hz then I am not sure that they would be ...

Nice work; bravo Mike! With regard to improvements to the S2: Apparently Romy's prayer, one of them anyway, has been heard and would seem to have been answered; a diaphragm-centering guide has at last been added. As for the rest (other improveme...

Hi Romy,How would such a time delay manifest itself in the resulting sound? Have you had the opportunity to listen to such an attempted system? Would the benefits of having a hornloaded AK151 not outweigh this or would it just sound too wrong to...

Hello Romy and everyone here, Thanks again for your thoughts on the large horns. It seems best to start a new thread, as previous threads dealing with the "10-Footer" originally began as discussions of other subjects. Romy, you may want to move previ...

Jessie, 45Hz horn with 6”-7” throat around AK151 driver is from my perspective is the best thing might be theoretically built around a cone driver. I really envy of you and if I had room I would unquestionably go for it; this is why I keep a pair of ...

[quote user="jessie.dazzle"] I might be totally wrong, but I just assumed that Vitavox's decision to specify a lower impedence voice coil for horn-loaded applications was related the additional load placed on the driver once mated to a horn, resu...

Thank you for giving this matter your attention. Jorge, I was intending that the AK151 be employed within a horn. Further, once I had settled upon the driver compliment, it was my intention to retain the services of Jeffrey Jackson, since I am not su...

[quote user="martinshorn"]The bass horn for the ak151 is housing a rear chamber slightly open, giving the injector channel - that creates a lot charme, flavor and „heart“ but also 3 dimensional projection. [/quote]I need to say that that very muc...

I'm listening near field (2m away) in a small, odd shaped space and they do give fun. The sound is somewhat compressed, lives between the speakers not spreading but on my list is to try to address it: bass modules, supertweeters (anyone selling Tanno...

Thanks for the recommendations on crossover points and the image of the rear chamber on your Upper Bass horn...

[quote user="jessie.dazzle"]However, I must say, I have a lot of trouble accepting the idea of redundant drivers. [/quote]
Yes, it dose not sound attractive to me but it is not the redundant drivers but one main driver and another at minus 9dB drive...

Here are a couple of shots of how the inner surface of the new rectangular mid-bass horn will look (shown with driver; an AK151). This model is based on a calculation for an exponential horn.These images do not show wall...

Hello Romy,Thanks for the great explanation, I'm a newcomer to horns, so please treat me gently ;-)Very interesting info, so in essence there are two limits, the real "hard" limit, where you risk damage to the driver, and the "sensible" limit, below ...

After a provisional cleaning of my crappy Yamaha C2 preamp, I got +/- balanced bass and then made a bit of discovery: Changed the parallel R in the HF circuit of the UK crossover from 50R to 25R (and switched the xcover to the treble boost mode which...

Hi Romy. Interesting point as i had similar perception along my recent I ran an 8inch driver with fronthorn. Then just got my hands on a pair of RFT L-3701 (or 3702). http://tempuri.org/tempuri.htmlA fabulous driver with exactly those parameters. T...
