Hi i want to build studio monitors for mixing, mastering and also just listening to music. A few things are already set. They will be 3 way with seperate closed boxes for bass and mid and i will use a hypex fa253 for dsp and amplification. The hypex plates can do fir filters since the latest update, so with some tweaking a fully linear phase system could be possible. Source will be my cheapo 2nd gen 2i4 Focusrite interface but I will upgrade to an RME with AES outputs in the not too distant future to have one less adda conversion. The speakers will stand on my desk and i will be listening in the nearfield 1m before i move to a bigger space someday. I want to make the cabinets from mdf or multiplex and they will be rectangular boxes, no fancy shape. Max spl is not super important around 90-100dB without detectable distortion is enough. I do want them to go very deep, down to 25-30Hz which should be possible with eq at the cost of max spl.
I want to use the 10" seas l26roy woofer, probably the 4layer vc version, which has lower qtc so that i can make the cabinet small and boost the bass with a linkwitz transform. The question is what midrange and tweeter i will use. There is the seas kingroy mk3 kit which uses a coaxial mid tweeter combo and has nice documenation for the cabinet and ready made dsp files for the hypex plateamp. Measurements look good aswell and it would be cheaper than the alternative. Coaxial is nice for nearfield listening which will be my usecase for at least the next year or so. The drivers cost about 1600€
The other version would be to use really nice individual drivers. Purifi 5.25" midrange and sb satori beryllium tweeter with waveguide, both with 8ohm versions so that the dacs in the hypex plateamp have to ouput more signal and thus have slightly better resolution. The smallest possible center to center distance between those two drivers is 16cm which is about 2150Hz in wavelength. The tweeter should be able to be crossed below that, how low depends on how much distortion i can tolerate so i will have to experiment. The purifi starts to beam around 1400Hz so I will try to cross there to have nice wide dispersion at all frequencies. 1/4 Wavelength of the driver spacing between mid and woofer suggests 440Hz as the max crossover point. Another question is the mid tweeter position on the baffle. Should i offset them from the center to minimize diffraction and/or use foam on the baffle? The drivers in this configuration cost 2320€.
What do you think, are the extra 720€ worth it for the nicer drivers? I guess in the midfield the more expensive version will sound better? Do my plans make sense at all? What are your thoughts on an atc style dome mid instead of the purifi?
