QuestionHi,
I purchased a new 12v car amp (specs below) in view of equiping my motorhome with decent sound for AV. The system will only be used when vehicle is stopped, at normal volume (read not too loud) for both stereo audio as well as for tv surround system. For video i have a 220v (in europe) dvd player with digital out, amp has dolby and dts decoding through digital in.
A) I now need to match sat speakers and a sub, and am considering the mirage nanosat speakers (specs below)
"Room" is about 12ft by 8 feet (without bed area in alcove). I would like to mount rear ones on the ceiling if possible, front left right about ear level (thus mid height) and center on same as front. tv is slightly above and left of center, with bed in alcove behind it. seating position for tv is slight right of center 3/4 way back in "room".
Questions:
1) will these "omnidirectional" speakers work well in the reasonably small space of a smallish motorhome or would i be better off with direct firing speakers (thinking about take eneragy classic).
2) Will the impendence be ok with the amp?
3) Other options/thoughts to optimize sound in this sort of configuration?
B) for subwoofer I have a double floor and plan to put the sub there if possible.
Questions:
1) size, seems 150-200w at 4 ohm is what would be required, correct?
2) I would rather a passive sub as am running off batteries, tho am not sure if this is best choice.
3) assuming passive, have found two options a pioneer sub TS-SWX310 or a JL Audio CP108TG-W1V2. Would appreciate your thoughts as well as other (perhaps more cost effective) solutions/options
4) to match the sat and sub, do I need to match/overlap the frequency response sat and sub, if so what do i need to look for?
thanks and cheers,
david
AnswerDavid,
I appreciate the thorough description of your problem. The nanoset looks to be a very logical answer to your audio needs. I am sure impedance will be fine with most amps. This system will require maximum 50 watts per channel. Realizing that every channel of a surround system needs its own power, you can buy 3 two channel amps, or 1 five channel amp. The four main and surround speakers need to be around 50 watts rms per channel which will really be overpowering. Second, the subwoofer must be active, and it must have twice the power of the regular channels. A passive sub is more like a tuned port for another speaker. It does not put out any power of it's own. An active sub is powered, and it requires about twice the power of the standard speakers. Both of the subs that you have researched will work great for your application. It is important to remember that they require twice the power of the standard speakers in this system. In a mobile situation as you state, you may not NEED 50 watts per channel, but any smaller power may run the risk of cheap equipment. If you have any more questions, please let me know, and I will be glad to make things clearer. Hope this helps, Scott
