Does the magnet size really matter? I'm sure Polecat can answer the question if you really need to know

it doesnt say in the tech manual im kinda surprised... but unless youre concerned abotu how much weight its taking up in your trunk then it really doesnt have any effect on performance. actually magnet size if often a misleading spec for people who dont know that weight doesnt matter. (like peak power)

magnet size doesn't dictate output.

x2, some manufactures have way too much magnet for the woofer...as long as you have enough to supply the woofer with what it needs, overkill, is just overkill.......

the magnet is as big as that one from that one time that i went over there and weighed it with a measurement thing. you know. that time.

honestly. that has absolutly NO bearing on how good the speaker is. so its a point that does not matter, and should not be compaired.

Case in point is Audiobahn.

x3.....but it has good weight......but again...magnet weight

has no effect

haha i saw some stupid *** sub with like a 1088 ounce magnet or something rediculously incredibly huge like that...

THATS overkill

 

[Trancer 10+ year member]

Yeah I checked in the L7 Technical manual and I didnt find it either. I use to have a 10L7 and a 12L7

hahahaha...this dude has got a point

 

[creater 10+ year member]

1088 ounce...thats just dumb

but yo my d0ooode had thi$ Wolefenmhagggg sub with thsi HUUGEGE A$$#$ magnet. SHIT BE BEATIN TOO HARD!!!!!!!111ONE!! so you yasll cant be knockin on them magnetzzz cause dudeS shit was TOOO crispy!!!!!@

people be looking errwhere when we roll in his whip with that GAIN AT MAXXX!@!@

Every speaker will have an optimal BL product, the field strength in the air gap multiplied by the length of the voice coil wire in the field.

If the BL product is too low, the speaker is electrically not very well

damped (which will result in a woofer with a high Qts). A bump in

frequency response and a level drop in midband efficiency may be the

result. If the BL product is too high, the speaker is electrically

overdamped (Low Qts woofer). A very high midband efficiency, but the

driver starts to roll of early.

An high BL product can be achieved in a number of ways: increase field

strength; or increase wire length in magnetic gap.

The increase in field strength is limited; so some manufacturers use

very thin wire for the voice coil, as such they can achieve a high BL

product with a low field strength (cheap magnet). Or they use an 8 layer

voice coil... needless to say that electrical power handling will

decrease enormously.

Long stroke woofers, having only a part of the voice coil in the air

gap, need a very high field strength to achieve a high BL product. Often

this means a big magnet as well...

Use magnet size as an indication, but as nothing more than that.
