Two questions: volume level for new RTi12 Yamaha V2500, noise in tweeters.

Romel

Hi everybody!
I was recently reading forums before 2007th - and found one man saying: "You don't need 360 or 500w @ 8ohms to drive the RTis...a couple of hundred will get them going"...

I have RTi12's and Yamaha v2500 (which is 130wpc/8 ohm) wired with <6 ft/each 14AWG. System was planed as musical (jazz, r&b, classical) stereo, maybe w/ further conversion to HT.

I'm wondering is it "not good", that I have to turn up volume up to -15dB (sometimes even to -12–10dB to start feeling the music, to hear every instrument in composition) and overall to feel some louder mids and basses. I took them this friday from store's Show Room, where speakers were standing. Seller wasn't able to tell how much hours were played on RTi's, but as I think, <30h is nearest to reality.

So how bad that sound level is for my receiver? Can it overload it? As I know, Yamaha has a security (protection) on overloading an amp?

----

second question is about a noise (sand like) in tweeters, but as I read, it's normal to new speakers, and I should wait for a bit more hours to play in.

... I have a lot more questions, but about spare/replacement parts, but i think i'll post them to support's email.


Guys (& girls) thanks a lot for your further help!

A receiver is not going to allow your speakers to live up to full potential for sure, but feel free to bring the volume up to even zero db. Just listen for distortion. Yes the tweeters have to be broken in. If the house is empty during the day turn them up a bit, and play some dynamic music all day long. Most break-in will occur in the first 20hrs.

I second that you really should get a separate amp for them. I have the rti12s as well and once i added the carver m 1.5t to it i help alot. But if you do like to really FEEL the music and when i say feel i mean like its hard to breath add an ed i have one from sound shaper i got off ebay for like 20 or 30 shipped and that was a major improvement.

O and sorry i forgot this but if you look at reviews on the yamahas like in home theater magazine they are overrated spechs wise still good stuff just if it says like 120 watts expect like 50 or 60 watts

I asked the same question last year for my AVR Boston Acoustics (110w x 7) when I got my RTi-12. I took the advice from guys here and bought Carver M-1.5t (350wpc) and some decent cables/wires -- I really love it. It makes difference!

Goodl luck and enjoy your RTi12.

Hey chargerman426, Audioholics benchchecked this receiver. Power is more than your 50 or 60 watts.

I had this combination at 1 time. RX-v2500 and RTi12s. I usually listened to movies and music between -20db to -15db. These volume settings were loud enough for me, but the room size was only 15'x10'. I was not satified with the bass coming out of the RTi12s. You will need a seperate power amp to push the low end. Try by-wiring the mains with your speaker A&B. While most say they would hear no difference, I thought the 12s sounded better, more distinct this way.
I also found that if you cranked up the treble, the tweeters sounded harsh or sandy as you put it. I always ran the receiver flat, no boost in treble or bass. Message me if you have more questions.

Your AMP will be fine, if turning it up to you sounds good then why not. You could bridge your amp to get 200 Watts out of it to your front speakers if you really wanted to, but the best way to go is a power amp. cv-1800 is what I got and I also have 130watts per channel... MAKES huge difference. It is 400 watts. but I got the boom feeling and the AHHH. hehe

Thanks guys! It's been a while from then, in april... Now, fall is coming, and my addiction to sound is getting bigger and bigger. In plans - get some vintage "amateur kind" turntable to listen to my granpa's LP collection.

In addition I have bi-wired my RTi12s with Monster's Cable M1.4s. Added a CSi5 as center. Did a DIY on marble plates as stands (They really improved the sounding).

And, I'm kinda sorry for such questions, dear polkians, but: I had a chance to buy a pair (two identical) KEF iQ2c center channel speakers, completely new, for a good pricing. And I did. Is it acceptable to use them as an rear speakers? Is it good to boost a low frequencies within the receiver's equalizer (in each channel)?

Oh, yes... the funny part. When I requested a replacement backside "stand" (which weights less than 3 ounces) for my CSi5, support team gave me a shipping charge option of 100$ Funny, isn't it? To send a part to Europe.

Thanks in advance.

You will not get much admiration for Monster Cable in this forum, sorry! Also, there are not many who consider bi-wiring useful. Just FYI.

Although it is not ideal, rear speakers that do not match the fronts are not a big problem. The center speaker and front speaker match is much more important. Those iQ2c centers seemed to be configured much like in ceiling speakers, so I would guess they should not have the same weaknesses as other centers (because of the mid-tweeter-mid configuration), even if used as rears, so they should be fine, but that's an educated guess.

I would not boost the low frequencies in each channel, unless you have no subwoofer (in which case you have no real choice but to allow the speakers to play full range as best they can). If your receiver allows it, you may want to adjust the crossover quite differently for those rear KEF and your mains (which have a much lower -3dB limit). I would suggest trying 80-100Hz for the KEF, maybe, and 40-60Hz for the CSi5 and RTi12.
