Ishiwgao 3rd Gear August 2, 2012 Share August 2, 2012 Hi. I have 2 options of speaker from the shop I am currently upgrading my 6.5 comps to. Without looking at brands,Speaker A -125W norm, 250W peak powerSensitivity 90dBFrequency 60Hz-20kHzSpeaker B -80W norm, 160W peak powerSensitivity 92dBFrequency 60Hz-20kHzMy amplifier is able to handle 400W per channel, so both speakers are suitable. Both speakers are the same price. Will the 2dB of sensitivity be my concern, or should I just go for the higher power one? ↡ Advertisement Link to post Share on other sites More sharing options...
Gee 1st Gear August 2, 2012 Share August 2, 2012 i usually go by brand first then by the numbers. although no 100% guarantee, some brands have better quality than others. quality also depends which kind, built quality, performance quality, etc. specs can be overblown and even if not, would we check it to verify? But assuming both speaker are somewhat OK brand, i would go with the higher power one. The power difference is quite big while the sensitivity is about the same.

AlanZ Neutral Newbie August 2, 2012 Share August 2, 2012 I look at the brand 1st too. Cause the reputable brands normally under rate their power whereas the not so popular ones over declare. Link to post Share on other sites More sharing options...
Wasted 1st Gear August 2, 2012 Share August 2, 2012 can google the speakers for reviews, btw 400w per channel is what amp? Link to post Share on other sites More sharing options...
Ishiwgao 3rd Gear August 2, 2012 Author Share August 2, 2012 amp is boss rev 800. supposed to be 300w per channel x4 at 2 ohm. but will bridge, and give discount for a few losses here and there, i just assumed 400w per channel as a safe number. thanks for all the replies everyone. I guess it's more than just power. will have to look deeper into the brands then Link to post Share on other sites More sharing options...

Without looking at brands, Speaker A - 125W norm, 250W peak power Sensitivity 90dB Frequency 60Hz-20kHz Speaker B - 80W norm, 160W peak power Sensitivity 92dB Frequency 60Hz-20kHz My amplifier is able to handle 400W per channel, so both speakers are suitable. Both speakers are the same price. Will the 2dB of sensitivity be my concern, or should I just go for the higher power one? Seems Speaker B could be a better choice. Lower RMS with higher dB is usually better without knowing the brand. Link to post Share on other sites More sharing options...
Fuelsaver Supercharged August 2, 2012 Share August 2, 2012 Then hi end sinphoni only 40w rms cannot be so jia at rite. Think it's quality more than quantity. Link to post Share on other sites More sharing options...
Tayspiderx 3rd Gear August 3, 2012 Share August 3, 2012 Be it brand or numbers, best if can demo the speakers, call up the supplier to check which installer hav sampler set up. If not i'll stick to the more rekown brand, mainly cos they waste no expense in R&D and reputation at stake. Other variable also can be material of cone, wiring and magnet.

Theoldjaffa Hypersonic August 3, 2012 Share August 3, 2012 when u buy digital cam, you don't just look at megapixels, you look at the photo quality right? same thing, audit the speakers. buy one that you like, at your budget of course. 1 Link to post Share on other sites More sharing options...

Timbuktu Clutched August 3, 2012 Share August 3, 2012 Hi. I have 2 options of speaker from the shop I am currently upgrading my 6.5 comps to.

Both speakers are the same price. Will the 2dB of sensitivity be my concern, or should I just go for the higher power one? The most important aspect of amp-to-speaker matching is the power amp's output impedance and the speakers' input sensitivity. Some audiophile power amps do go to as low as 2 ohms on output impedance. If you try to match that with lower efficiency, hard-to-drive speakers - e.g. ribbon speakers at 88 dB, you will end up turning up the pre-amp's volume dial to way past 12 o'clock to get decent sound ... if not near full max! Similar, matching super-efficient >96 dB speakers (e.g. horn-loaded speakers) with power amp output impedance of 6 or 8 ohms may be so loud that you get speaker cones deflecting/warping near its peak power limit at even 9 o'clock settings ... that is if you don't get the output transformers clipping before that. For amp power rating, single-ended tube power amps generate very low power, in exchange for sound quality and higher resolution. These require efficent speakers >96 dB typically.

Dclk Neutral Newbie August 3, 2012 Share August 3, 2012 This is new to me. It does make sense though. I will look into it I agree with Chickensoup. With a higher sensitivity, speaker B is easier to drive. I am assuming both sets of spekaers are of comparable standard. Link to post Share on other sites More sharing options...
Liping24cn Clutched August 3, 2012 Share August 3, 2012 Would go for the one with the higher RMS rating. As it will have 'stronger' coil. N will act as buffer to accidental over-volume from the high powered amp. One thing to consider is the cross-over between the speakers n tweeters. Not all crossovers are the same, some have higher resistance n capacitance, which will definately affect the 'power' that reach the speakers eventually. Assuming both speakers sound quality is the same(sound is subjective anyway, n my ears is not into detailed sound quality), so I will definately chose the higher RMS speaker! Also the equalizer in the HU can somewhat tune the frequency response of the speakers to make it sound 'nice' to my ears. Link to post Share on other sites More sharing options...
Ishiwgao 3rd Gear August 4, 2012 Author Share August 4, 2012 for those in this thread who wants to know, Chickensoup and Dclk are right http://en.wikipedia.org/wiki/Loudspeaker In the examples that follow, assume (for simplicity) that the drivers being compared have the same electrical impedance, are operated at the same frequency within both driver's respective pass bands, and that power compression and distortion are low. For the first example, a speaker 3 dB more sensitive than another produces double the sound power (or be 3 dB louder) for the same power input. Thus, a 100 W driver ("A") rated at 92 dB for 1 W @ 1 m sensitivity puts out twice as much acoustic power as a 200 W driver ("B") rated at 89 dB for 1 W @ 1 m when both are driven with 100 W of input power. In this particular example, when driven at 100 W, speaker A produces the same SPL, or loudness as speaker B would produce with 200 W input. Thus, a 3 dB increase in sensitivity of the speaker means that it needs half the amplifier power to achieve a given SPL. This translates into a smaller, less complex power amplifier Link to post Share on other sites More sharing options...
