Pioneer S-1EX Loudspeaker

I'm using my 180's at half power (About 90 watts)with KT88's. Its just that these are the only amps I have right now. I put some EL34's in them and they were super warm.

I unfortunately spiked them when I was tube rolling. I forgot to turn off one of the amps. I had pulled a power tube and a signal tube and heard a huge CRACK BANG, but the speakers still sound the same. Nothing broken. I'm worried about the tweeter woofer combination getting cracked. Hopefully there is no damage. I will be rolling in the EL34's today, far less power and super warmth.Will report back later.

The EL34's sound the best as they are less powerful then the KT88's and the KT90's. These speakers really don't need super powerful amps.

Hey Zeal,

So you got around to enjoying the sound of the EL34's more than the KT88/90's? Have you ever gotten remotely close to clipping the amp/s at extreme volume levels or are you getting darn loud levels even with the amps not even using much power?

I'd be very curious how others that own Tad based speakers find tubes vs. these Ice/Class D/T/etc. amps to sound. I know only one other person on a forum using an EL34 tubed amp as the main amp, but always see the shows using these Ice amps or some kinda Japanese SS type amp or even HT receiver.

These are basically 90db speakers so I truly struggle to find any reason whatsoever to need more than 5-20 watts to get serious output, and around 40-50 to get levels that are obtrusively loud.

Good to hear you are finding more ways to optimize the speaker:)!!! Personally I don't see anything on the market since Tad began marketing their stuff some 12? years ago that approaches this level of sound. Even though Pioneer is a lil different design, the transducers being used, at least in the 1EX w/BE tweeter, are identical to Tad's Evolution One which has been tough for people to identify in a/b testing against Tad's CR-1's. I'm sure the Ref Ones would be a lil clearer, but how much clearer does one need it to sound?

Cheers!

The Rogue monoblocks with EL34 tubes at half power sounds great. The speakers can only take 160 watts. I put up some Auralex acoustic panels behind them and some Herbie's isolation feet under them for easy moving. Can really hear the speakers now. Never heard the Tads with SS, be nice to try someday.

Was reading earlier in the thread about the Tads vs. the Pios. Can people that have heard both say there is an indefinite difference between the two or that it's a matter of taste than it is one speaker being superior to the other? Way I see it is we have what are the absolute finest transducers (dynamic) on the planet. How can it get any better via Tad other than the BE mids and the slight better motors on the bass units of the Ref Ones? I always see this percentile of something, and many believe the Pios are 90-95% of the Tads. I'm very curious if we can make a percentile or if we can say it would be difficult in an a/b to say which one is Tad and which is Pio. I loved the Youtube clip with Andrew talking about the Tad E1's vs. CR-1's and saying to the audience, but you were hearing the E1 and not the CR-1, as if they are so close in sound that it's hard for anyone to say which is what speaker. I also know many that feel the E1 is the superior speaker over the Reference One, and also know the E1 is w/some slight things, identical to the Pioneer EX1. I'll go on a limb and say if we had all Tad's offerings and Pio's offerings on hand, behind a curtain, we would all be fooled as the sound is probably that close to tell the difference w/exception of few golden ears that can hear some slight differences maybe from the BE mid and again the dual 10's in the Ref One would easily give them away:)).
