Can't figure out how to rotate the picture sorry.

My system-in-progress.

Main source is Asus Xonar DSX S/PDIF coaxial to input selector/ADC box (for an occasional analog source), to 75/110 ohm Neutrik transformer to digital input on DCX2496. Power amplifiers: t.amp TA-450 for mid-highs above 438 Hz; TA3020 based class T amp for midbass; temporarily a bridged STA540 chip for subbass. Speakers are Thomann 18-500/8-A for subbass (build thread here), Fane Sovereign 8-225 for midbass, ACR TT-50 titan dome for mids and Seas 22TAF/G for highs. Frequency response measured from listening position, 1/12 octave smoothing. Ignore roll-off above 10 kHz, my measuring mic has limitations

To-do: proper amp for the subwoofer; Scan-Speak Discovery 10" woofers in sealed cabinets for midbass; proper finish for the speakers.

It sounds, well, real. As in you're really listening to music, not speakers. The TT-50 has it's quirk - rise in 3rd harmonic distortion at around 4 kHz - but it's still below 1% and not really objectionable. The 22TAF/G is easily among the best dome tweeters I've ever heard; no metallic harshness usually assotiated with metal domes, and no unnatural dullness that is plagueing many soft domes. The cheap Thomann 18" driver is not the lowest or loudest and needs EQ to get flat, but, again, sounds real. Double-bass and drums sound just like that, real instruments, not some plasticky imitations of ones.

Can they ever be large enough? It's actually "only" ~360 liters Vb (compare that to some 500+ liter LLT-s with one 18" driver built by home cinema nuts). It's 1,5 meters wide, but depth of the cabinet is just around 40 cm. About 225...300 liters tuned to about 25 Hz is normal for real 18" cinema subs, I made mine just a bit larger and tuned lower.

I love the design of the base of those speakers in particular! Nice and spacious..

Do you have a build thread anywhere on the internet to look at?

Only in Dutch. Speaker built starts around page 17 (Thread starts with a different build of mine, at page 17 this one starts)

Speaker built: forum.zelfbouwaudio.nl • Toon onderwerp - Project #2: Vloerstaander
