hi Steve
your horns look great, too.
Yes, i am playing with the idea to try out a tapped horn. I know there is improvement possible in the bass section of my system, nevertheless, that i like my basshorn very much. It extends wonderfully down to below 30hz, and has great punch and control. But there are also shortcomings, which i would like to overcome with time. What i would like to have, is more even and extended vertical radiation of bass, ideally from a bass row. The exit of the Tapped horn is relatively small, what indicates directionality. So maibe a bass row of for example 4x 12" woofers each side , and a tapped horn below, would be interesting.Are you considering a tapped horn?
yes, i have read many positive things about these.I have found they integrated well once sorted (I originally had crossover and Zobel issues) they work really well doing nice deep bass support on normal stuff and where there is sub bass you hear that too. They are fast too not ponderous booming away.
i lowpass the bass horn at 150hz/24dbWhat frequencies are you crossing at?
i highpass low midrange horn at 150hz /6db, lowpass at 1,2khz/12db, the Beyma at 1,8khz/6db, and the S2 blends in at 700hz, but is padded down with Lpad. It just helps to broaden up a little bit soundstage. Its not essencially necessary, and since S2 is a rather expensive driver, and a wast to use in that way, i am selling it, and will replace it with a pair of Coral M100's, which are laying around....
The whole system is adjusted to match the efficiency of the Beyma, about 102db/wm. S2, and lower midrange horn are padded down, and the bass horn is active.What efficiencies do you have / measure?
It never disturbed me, but definitively worth to make a experiment , and see if it brings some benefit.Do you find that sound coming off the tweeter hitting the backs of the other horns and interfering a bit to be a problem? I experimented with acoustic absorption there and found it beneficial. Cleans the already pure horn sound up a little further.
Well, the Beyma actually eliminates the need of a dedicated midrange channel, since it covers nicely above 1,2khz. There are some very interesting 2 way solutions with it.5 way really is the way to go I think.
I use the bass horns active, with Inosic RAS300 plate amp, and the other channels Viva Solista SET amp. Lower midrange, and Midrange S2, i use LPad.Do you have one amp and L-pads?
Many go this route. Have you been able to make direct comparisons , do you feel multi amping improves sound perceavably ?I still use passive crossovers but use 5 amps, one per channel and level adjust on the line side.
