Jbrown has them and in his opinion the seos tempests are 95% similar. Close enough for me.

Yes. Jbrown will probably chime in but I think he said the top end of the jtrs was a bit better. I will be hearing both at his gtg. If its for mainly movies I don't think you would hear much of a difference. If you listen to a lot of music you might want to look at using the ae driver.

Are you space constricted to something the size of the 228, which iirc uses 8" woofers?

The top end on the JTR's just isn't brought down as much as it is on the Tempest because the designer for the Tempest was shooting for a more laid back sound like his other speakers. That's in the crossover.

The high end in the Tempest can be taken back up 3db by leaving out one of the 2 ohm resistors.

Warren I believe felt they sounded almost identical. I will be very interested in hearing for myself.

I need to get more time with the Tempest and will the chance next month to be able to compare then directly to my 228HT's for 10days straight before I host the GTG. But from the half dozen songs that we listened too I could tell that the 228HT's very a little more detailed. I don't think the Tempest were more laid back compared to the 228HT's either.

Erich have you had a chance to hear any of the new Neosis speakers from JTR? Or are you just saying what you think the differences are?

I will say that for the money the a Tempest are a great speaker!

no not space restricted


I just found the 228s interesting and I don't think my sides and surrounds could keep up with much more output then 228s would have

I know for a fact that my surrounds can't keep up with my 228HT's but that really only matters if you're listening at insane levels. For movie use I don't think it's as big of a deal. If you planned on using your 170's as surrounds I'd be willing to bet they could keep up to reference for movies.

Yeah I had a chance to hear the 170's last week for about two full days as I helped my buddy put together a system using them as surrounds and the 340's as mains. You'll definitely have to max them out with your AVR to level match them but after hearing them at pretty loud levels I would think they'd work fine with a high sensitivity speaker like a 228HT or Tempest for movies.

I thought they sounded pretty good, pretty impressive mid bass from the 340's for a $300 speaker.

Bagby's speakers are all "voiced" close to the same and he keeps winning speaker design competitions......so the Tempests as designed and as sold by Erich are probably as good as you'd want. As for music, he states that they are excellent "rock" speakers and I can tell you from my personal experience with them, I really enjoy the punch in alternative / goth / industrial rock with them.

I am very, very impressed with them.

wow cool rock is my favorite genre and I love to crank it up.


one thing that I love about my 340s is the tweeter and how it never bothers my ears even when loud for long period of times.


I normally am not a fan of horns especially klipsch but I have that the horns on the 228s are not very fatiguing at all. I hope the temptest has the same attributes in that particular category


as of now im very interested in building 3 of these temptest speakers

I was strongly considering 212's or 228's, most likely 228's. I talked to a few people who had been at the GTG where the SEOS speakers and the JTR's were played. I told them my primary focus was movies and I was told that for movies they were very, very close. For music they liked the JTR's more but put them at 90-95% as good for music. For movies they put them even. I went with three Tempests and I'm happy I did. Especially for the money difference.

I'm really looking forward to getting a chance to compare the 1099's and Tempest up against my 228HT's, but I'm really looking forward to hearing the 1099's. I'll have a chance to compare some Tempest directly against my 228HT's for the entire week before the GTG that I'm hosting. But like Jeff said I think it's a fair assessment to say that the Tempest would be 90-95% of the JTR speakers from the limited listening I was able to get in with the Tempest when I had some in my basement.

what have guys been using for a center with the temptest? another temptest would prolly work but id like something that lays horizontal because it would fit better in my space.

You might be better off without a center if you can't put one reasonably close to ear level though
