[QUOTE="Caleb Dueck, post: 2983, member: 60"] We had another round of speakers together for comparison, this time with Smaart, and captured raw and processed freq/phase for all speakers. However, due to a technical glitch, those all evaporated. I'll try to get the 15" speakers re-measured. [B]12" plastic[/B] - RCF Art722A, QSC K12, Yorkville NX55P, and Mackie SRM-450 (for reference). [B]15" wood[/B] - RCF TT25A, VTC S4P, and QSC KW153. Speakers were run from an EV DC-One DSP, which we commonly include with small portable systems. All speakers were lightly EQ'd flat where needed, and all had about a 90Hz HPF. This was to equate to real world use (tuned rather than raw). We used a well-known track, non-mp3, and adjusted fader so no speaker had a SPL advantage - IE, slightly louder sounding better. I have photos of the two groups attached. [B]In order of ranking, 12":[/B] Overall – none of them sounded good, they were all poor in different ways. No one wanted to go back to re-listen to any of them. RCF 722a- least bad, scooped, needs a lot of EQ to sound good. Large 2” horn, a bit louder than the rest. QSC K12- muddy, needs EQ, not very loud, limits early and hard Yorkville NX55p- even more muddy than K12's Mackie SRM450- very harsh, even at low levels. [B]In order of ranking, 15":[/B] Overall, the TT25A and S4P were better than the QSC, which sounded plastic. RCF TT25a- The overall best by far, tight bottom, loud, physically compact, no extra buttons to confuse novice users, powercon. Clear winner. VTC S4P- most open mids/highs, but slightly weak and flabby low end. Quite large physically. Makes me want to hear biamped U215, and 2/side S4P's, with Bonded Logic acoustical stuffing. Uses Synergy Horn tech licensed from Danley. With subs would be a solid option. QSC KW153- very forward mid-range but not in a good way, needs EQ, very tall, way too many knobs and buttons to confuse novice users, very ‘plastic’ sound, poor limiters, quite harsh at higher levels, not as much max output as it should have. TT25A's over a Danley DBH-218 is my current favorite little portable system. [/QUOTE]
