So i've got new to me Pioneer S-2EX fly in straight from Japan to Tx. Looks like customs dropped them and damaged the cabinets and broke the grills-only cosmetic thankfully as the cabinets are built like tanks. ENORMOUS stand mounts.
I'm aware Andrew Jones wanted these to be sold as TAD speakers. They utilize TAD drivers -though the wiring, "Spirit" caps and inductors and resistors may be more budget as well as the binding posts and jumpers. I had already planned in the future to upgrade the parts to more premium parts. The speakers getting cosmetic damage likely forces me to do take the drivers out and refinish the speaker anyway so i'll just do the crossovers and cosmetics at once, but it got me thinking about skipping the passive networks.
I know these speakers need lots of power. I only have tube amps. Audio Tekne transformer coupled 6550(modded to use RCA 807) push-pull amp with about 30+wpc. I also have these great little rebuilt Eico HF-14 monoblocks. Both sound great with the speakers as long as i go through my subwoofers high pass filter at 100hz. Otherwise there's just not enough power to wake that woofer up. I even tried a Yamaha AVR to power the LF, but it still wasn't enough. Without a sub, the sound is unbalanced with the tweeter slightly hotter than the mids which almost kind of drowns out the mids a bit.
It's the best tweeter i've personally ever heard and as someone who has dealt with bad tinnitus from years of owning Klipschorns and La Scalas and every Klipsch heritage speaker horn blasting at my ears at dangerous levels, forcing me to leave traditional speakers for Omni directionals. The Omnis never set off my tinnitus. This was my first step back into traditional directional speakers and i had heard Focals with beryllium tweeters in the past. Made my ears ring like crazy so i was truly worried these would do the same. They don't. They're beautiful. Extended with long decay. They're the stars of the show, but completely hog all the attention if that makes sense-at least with the power i have on them.
How much of that non fatigue, non ringing attributed to using tube amps? If i switch to SS/Class D, will it wake the mids and LF up, but set off my tinnitus? Live with the trade off?
Will investing in a solid state amp for bi-amping the LF be even worth while? It's only 400hz down and my sub would take over at 100hz. That's an expensive route.
Has anyone actively bi-amped TAD/Pioneer S-EX models? Crossover points are easy to find, but how do i protect the drivers from damage being directly hooked up to amps?
Thanks
