Default Subwoofer question

Okay so I'm upgrading my system...and I'm buying new subs...I need to know if Audiopipe TXX-APX12BL 12"s are good subs. They're in my price range and some buddies of mine are saying some good stuff about them.

Maybe for a vehicle, but inductance [Le] is way too high.

Le is the inductance of the voice coil-it can act as an inbuilt passive crossover-but at the freq's the subs will be playing they'd already be outside of the range of it.

Personally I'd stick with the Audiobahn over the Audiopipe-I've heard relatively good things about their amps-nothing good about the subs..

For a vehicle app, yes, not a typical HIFI/HT app where this much inductance creates a large mid-bass boost, forcing a very low XO point.

Regardless, for a good sound quality [SQ] app I'd want an Le = < 1.25 mH and < half this for high SQ.

GM

edit: If a driver's 'Le' spec isn't listed, best to assume it's very high, especially if advertised for a car audio app.

DCON-12 D4 ? Sound Solutions Audio 12" 300W Dual 4-Ohm DCON Series Subwoofer

they make em in d4's too..a pair wired parallel gives ya 1 ohm...I have the PB 2XL15's i mentioned earlier wired series/8 ohm per sub and both of them wired parallel for a 4 ohm load to the same amp u got. The difference in SQ/no heat buildup in my amp, etc more than made up for the little difference in spl. I am going to grab a pair of these in 15's because they are the best deal I have found on truly 100% american made subs...did you check out that triple mag stack?...geez..and oh yeah they will handle anything you got in that Hifonics 2000w amp. If you get a chance, clamp it....Mine clamped at 1750 watts/1ohm...about like what other folks get with that amp.

BTW...If you do go with the Audiopops, watch out for the surrounds..I hear they like to separate from the frames around the bolt hole circle.
