Hi Guys:
I have a pair RTI A7 and recently blow the 2 midranges and 1 tweeter. Already replace the damaged speakers but I want your help to avoid this to happen again, my configurations is:

Amp: Emotiva XPA-2 Stereo amp
Power Output: 500 watts RMS@4 ohms (0.1% THD)
250 watts RMS@8 ohms (0.1% THD)
Power Band Response: 20Hz to 20kHz with less than .05db deviation at rated power
Broadband Frequency Response: (-3db): 5Hz to 150kHz

Signal to noise Ratio: 1 watt: >91db full power: >110db
Input Impedance: -23.5 kohms

The RTI A7 specs are:
Power Range 20-300
Frequency Response 35-26k Hz
Sensitivity 89 dB
Impedance (Ohms) 8

Thanks in advance for your help

    Turn it down.....
    Best way to avoid
    Help us out list your other gear as well. How are you using them music, movies, both? Type of music?

    I only use for music mostly with CDS, sporadically with IPAD but very low volume. My other gear is:

    Preamp: Emotiva USP-1
    Preamp Audio Section
    Phono Input: Moving Coil - 240 Ohm Moving Magnet - 47kOhm
    Input Impedance Line In: 47K Ohm +/-5%
    Signal-to-Noise Ratio (rel 2V out): >116dB (ref 2V)
    Distortion: < 0.005% 20Hz - 20kHz with 80kHz measurement bandwidth
    Frequency Response: 5Hz - 80kHz, with less than 0.05dB of deviation
    Line Out Freq. Response: 5Hz - 80kHz, with less than 0.05dB of deviation
    Maximum Line Out Level: 9V RMS
    Ground Floor Noise Level: > 20uV
    Channel Separation @ 1kHz: > 80dB (same as line)
    Built In Filters:
    High Pass = Variable 50Hz or 250 Hz @ 12dB/Octave
    Low Pass = Variable 50Hz or 250 Hz @ 12dB/Octave, Summed L+R Mono
    Other Details
    Trigger Output: 12 VDC, 3.5mm jack, Center Pin is Positive / Current Load <120mA

    CD Player: Emotiva ERC-1
    Output voltage: 1V rms (7V peak)
    Channel separation: ≥95dB - ref. 1kHz
    Frequency response: 20Hz~20kHz (+/- 0.1dB)
    S/N: ≥100dB (A weighted）
    THD: ≤0.01％ 0dB 1KHz）
    Playback formats: Redbook CD, HDCD, MP3
    Digital Output Filter: 24-Bit, 384 times oversampling (Analog Devices 1955）
    Sampling Frequency: 44.1 kHz
    Analog output filter frequency: 80 kHz (-3dB)
    Amplitude output linearity: 0.2dB
    Phase linearity: 30°

    Thanks again

    There is no reason you should be clipping with that amp. You have plenty of power and those speakers are very efficient. As mentioned you are playing entirely too loud or your trying to fill a concert hall.

    I have had a similar setup with the xpa1's at 600wpc per channel a usp1 preamp on rti12s. Played plenty loud quite often with zero issues.

Now there is a lot that bird don't know, but it don't change the fact that the world is happening to him all the same. What I am tryin to say is, is that the course of your life, well its changing, and you don't even see it- Forest Bondurant

    There may be something else going on. I would pull the crossover for an inspection.

    I almost cut my hair today.
    If it is distorting, it is too loud.
