Post Subject: Why not ET-703Posted by Murataltuev on: 8/18/2015

Yes, there are a lot of paths.I can see that many DIYers are very much stick on crossovers, changing capacitors, choosing slopes in digital filters - FIR or not FiR and so on.I know very experienced people who now say that with digital crossover he doesn't need to care about quality of amplifier, that 3 poor chinese D-class amplifiers works better with digital crossover than single SET with passive crossover.And they don't care about choosing right driver and choose them according spec only!Well, this is also a path.My path is only experiments. I hear everybody, but then I need to try and decide.ET-703 has great reviews around. But it just can't give right tone under 8khz and gives almost nothing higher than 12khz.So, there is just no use for it in my system. 1.5 octave is nothing.May be one day I decide that I needs 7-8 way speaker with digital 48db/octave FIR, then I use it.Also with all my experiments with HF drivers I come up to idea, that for HF I don't need horn.I even considered the idea to get some conventional tweeter for highs with separate amp to compensate sensitivity, but then I found RAAL.If RAAL will not work for me, than I go for top SEAS...I heard it ones during Munich Show and was very satisfied.So, it takes few month of experiments to decide:
1. I need separate driver for 12k+ range
2. It will be RAAL or I go for conventional tweeter.
How much time I'll need to decide about other ranges I don't know and don't care.This is our hobby and process is even more important than result Smile
