Pioneer S-1EX Loudspeaker


As a fan of TAD loudspeakers – but not in the proper tax-bracket – I am curious about Andrew Jones’ design for the Pioneer brand – the Pioneer S-1EX floor stander (which is essentially a baby TAD with the Pioneer logo). Does anyone have any experience with this speaker see here

No matter where I place them the tweeter sounds a little scratchy and over the top. Any suggestions?
I just got a pair of Pioneer S-3EX Loudspeakers. The more you play them the better they sound. They need about 400 hours before you hear what they really can do.

How did you guys set them up and how close to the walls were they? These things are so new to the American market that's there's very little set up information to be had. I have a 16 by 14 foot room with 9 foot ceilings. Any suggestions?
I have my S3-EX 16 inches from the back wall and 30 inches from the sides. They have warmed up a bit since I got them, I still don't think I have them in the right place for the best sound.
I have them toed in but not all the way and I put some rubber and cork footers under the back legs of the speaker. I wish that 5th foot was a little longer as I put the cork flats that came with the speakers under that too. It sounds very good but I think it could sound better.
If I were to toe in my S3-EX in my 16.5 by 14 foot room, I would hardly see the front of the speakers. I have them toed in so the axis cross is right where I'm sitting. As far as Tad speakers being bright, they were just a bit bright when I got them new, however the more I listened the warmer they got.

How far from the walls are they and how big is your room?
John Weirs told me it wasn't necessary to rack them forward. I have my S3's 25inches from the back of the speaker(about 44 inches from the front panel)to the front wall and about 37 inches from the center of the speakers to the side walls. I tried them closer a to the front wall and further away from the side walls but it didn't sound as good. I'm not using any absorption and diffusion panels on the walls but could use some absorption on the sides. 2chnlben, if I were you I'd bring them out a little further, like 3 or 4 inches...just a thought. Enjoy your Pioneers.
2chnlben,
Be sure to let us know how you set up your S-1's and how far away from the walls you place them. I'm still trying to get maximum sound from my S-3's.
Try this... Disconnect one speaker from the amp - either speaker - (turn amp off and remove one set of speaker cables from the amp).

Meaning , listen to the tweeter only on one speaker? I have mono blocks, so I just leave one turned off. I hope I have that right. Thank you very much for that test. I prefer warm speakers but I know just what you mean when you say "Balanced". These speakers are very planner like and remind me of my Martin Logan's in some ways, good thing I have a subwolfer. Sounds like you have them "Raked" very high in the back. What did you use to do that?

Got the speakers in the right place. Put some Herbie's Decoupling/Isolation feet under the TADS and put some Auralex B22 Elite Pro Panels on the walls behind and to the side of the TADS. Now it sounds right to me. I can hear the speakers now and not wall slap or the floor. I'm driving them with Rogue Audio Mono 180's and the Rogue Athena pre amp.
I'm still experimenting with toe in and the length from the back walls. Remember I have the S-3EX, my room is too small for the S-1.
I thank everyone for their input.
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.
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.
Audioexcels.....Dude, you sound very excited about your TADs, and you should be. I love my S-3EX'es like nobody's biz. I was taking a chance when I bought them and relaying on reviews.....wow, they we're right. Don't let the Pioneer logo fool you. It says TAD on the back and when you turn them on they say MUSIC. I have them 38 inches from the side walls to the center of the speaker and 34 inches from the front of the speaker to the wall, no cancellation I hope. Auralex acoustic panels all around as everything is up front. Super warm and dynamic, Electrostatics look out.
Nothing thin about the S-3EX, they're nice and warm with tubes and sound about the same with solid state amps. Turned out to be a great buy. Let them break in.
I'm listening to the speaker slightly tilted forward using a Herbie's loudspeaker Decoupling/Isolation footer in the rear with the 2 back feet of the speaker slightly extended from the floor. I had the Herbie's smaller Spike decoupling feet in the front but replaced them with the steel footers that came with the speaker. I can't tell yet what sounds better. My next move will be listening with all four feet to the floor. That 5th foot in the back makes it ideal for the speaker to rest on 3 feet thus lowering any vibration and giving you more latitude on placement. How can you hate a speaker like this, it's warm and un-colored.
All I hear is music.
