rti150 or rti70

licer

need help in deciding between these two speakers. Will be using them 70%ht and 30%music

real simple, if you have a good sub, go with the 70's

I've spent a good amount of time listening to the 150's, and although they do have more low end, it doesn't match the depth a good powered sub can give you.

Plus for the same price you can get the lsi 15's which isn't much of a comparison.

So the only reason I'd get the 150's is if you have all RTi's and want to keep it matched and a large budget to play with.

Most music don't go down to 30Hz anyway. Also, a HT receiver seems to be designed for use with subs anyway.

But the weight of the amps can add stability to RTi150. Right?
Plus the RTi150 would look better without the added clutter of cube shaped subs.

If you're planning on getting some amps in the future, the RTi150 should be a great choice. This is a speaker from Polk I really want to hear but can't find a demo with them yet. With good amplification, the six 6.5" subs should really move a lot of air. They were on my short list of speakers to purchase when I was upgrading.
Find a good dealer that will allow you to demo the 150's using good amplification and I'm sure you'll be impressed.

Licer,

The most important thing is that YOU listen and YOU decide whether it's worth it.

However I have spent HOURS listing to both these speakers and I can confidently say that the 6.5" woofers are no replacement for a good powered sub. I also found it lacks more with HT than with music, and since you're mostly planning to use HT, a sub is neccesary. If you don't want a seperate sub, be sure to give the RTi100's a listen.

For 70/30 go with the 70's, run em on small, and get a separate sub.

Guitar crushed it - the 150's are a waste unless you run them on large. And on large, they don't do bass as well as a great sub.

Furthermore, you are looking at a minimum of 350-400 WPC amp to drive the 150's to room filling bass volume for HT (if you don't want a separate sub), and that's big money for the amp.

I'm driving my 800's with 110 WPC and my SVS with 525, so you have 750 bundled between the two.

i have rti100s and despite what everyone says about how they produce no truely deep bass or sumthin i am quite happy with them their bass definetely shakes things and its very easily felt. however this might be because i have never truly had expirence with a high quality sub in a high quality surround sound system. but whatever the rti150s and the rti100s are both very nice speakers (i have listened to them both) i like the bass on both, however i did notice that the rti70's have better quality midrange but with much much less bass, so if you decide you want a sub then i would go with the 70's but if space does not permit you to have one then i would look into the rti100s or rti150's or like guitarhead said look at the lsi 15's. can't give you any info on them i have never heard an lsi speaker before but the specs look nice even if they are alittle less efficient then the rt series. honestly the best advice i can give you is dont take my advice, listen to the speakers yourself and decide whats for you. you will probably find yourself going crazy trying to decide but if you aren't 100% happy just return them and get a different model.

thanks a lot for all your help. Just visited circuit city today and was shocked to see a polk audio rti70 open box that was just returned and in good condition without any scratches. Got these baby for $400. Now, looking for a good sub to go with these speakers. Is the svs model 25-31pci a good match? Any other suggestions will be greatly appreciated. My systems are: onkyo txds898, rti70 for front, fx500 for side surrounds, rti28 for back surrouds, and csi40 for center, panasonic dvd.

Congratulations on a good purchase! The LSi70 is awesome. I might try open boxes.

Licer,

Dang, you lucky SOB. You got quite a good deal there. I paid almost that for my R40's and I thought I got a good deal.

Licer,

Great pickup on the 70's man. The 70's with a SVS sub will be absolutely great. I was just checking out the FR on the SVS subs compared to the more expensive models SVS models. Nice performance down to 25 hz. HSU makes a nice sub too (you might want to check them out too). Doc can help you out with a nice selection of subs.

You have the makings of a GREAT system.

The curves shown above are for an anechoic chamber with no room gain. Actual in room response will be much flatter and more extended.

With all ports open, my 20-39PC+ displays significant room gain peaking at 23 Hz, and then is -3 dB at about 16 Hz.

With one port plugged, the curve approximates an EBS design and is actually flat (with room gain included) to 11 Hz.

I am an admitted SVS fanatic, but only because I believe so strongly in the product and its incredible value. SVS is tops at each price point.
