Crystal Mobilesound Comp 10

[mr_ruready 10+ year member]

Has anyone heard the Crystal Mobilesound Comp 10? I plan to pick up one and run it in a 1.25^3 ported enclosure with 300 watts rms. How much output could I expect from this setup? Would sealed be better? I mainly listen to Classic rock, hip-hop and alternative. Would a 12" give me more bang for my wattage?

Their site says that the port has to be 4"d x 15"L. The enclosure is going to be only 9" deep, can I use a PVC elbow and bend the port? Would that effect the port? Can I use a different sized port all together?

http://www.audio-n-more.com/Merchant...ct_code=COMP10Only thing I could really find on it. Says 500 watts RMS there. Output would be decent I suppose, what sub won't with a decent amount of watts.

And I would go with no..only 100 more watts RMS for the 12".

So are you saying that you recommend the 12? I didn't understand you reply.

Crystal makes some good SQ subs - not sure about how loud ported, but I would note the tuning of the box you describe makes the F3 value up very close to 40Hz, kinda high IMO.

No, I am saying I don't since it only has 100 watts RMS more.

lol because it's 100 watts more has nothing to do with performance...I don't think you know what your talkin' about.

I can't comment on them though. Because I don't know what either are like and let alone I've never heard of them.

Sorry, those specs were from another sub.

Here are the specs from Crystal's site:

Recommended Ported Enclosure

Total Enclosure Volume: 0.9 cu. ft.

Port Diameter: 3 in.

Port Length: 12 in.

Fe: 33 Hz

Can I use a PVC elbow to curve the port?

Crystal are solid prerformers....I am positive it will exceed your expectations

Would I get more output @ 300 rms with a ported or sealed in your opinion?

Can I use a PVC elbow to curve the port?

yes on the curve - the distance should be measured down the middle of the path of the pipe, including the distance around the curve

Yes you can curve it, it will be louder ported at 300w, and if you have the means to get more tahn 300w, or even at 300w, I would more than likely take bets the 12" would be a bit louder than your 10" woofer.

Would the difference in output be significant in your opinion? I would like to save the space if possible but could sacrifice a little more space for a significant boost in output.

The specs for the 12" are:

Recommended Ported Enclosure

Total Enclosure Volume: 1.6 cu. ft. (.90^3 for the 10")

Port Diameter: 4 in.

Port Length: 15 in.

Fe: 34 Hz

I was pretty impressed when i heard a pair of Crystal CMP 8's in a P4S double shot box...metered on the termlab at around 147ish...

 

[mr_ruready 10+ year member]

I think I am going to go with sealed. Would using an Epicenter help boost some of the output since I am only going with 300 rms?

The Crystal CMP (and COMP) are very nice little drivers, you wont be disappointed. Hell, they're also some pretty handsome little subs too.

Anyone dealt with this site before? Are they legit?
