Hi guys just joined up good site for info... luv`it.
Well i just finished putting my cabs together with Legend BP102.
2 4x10 REAR ported cabs modeled loosely on the Fender pro cabs for size loaded with BP102` 8 in total. Now ive been reading some of the comments around this site about these BP102` & dont agree. People saying that they need this & that `big cab` `midrange speaker` & tweeters`............. all crap if you ask me, they are solid preformers.... professional speakers.
The thing i can hear is that they produce MASSIVE amounts of bottom-end.Easily as much as a 15` no worries if not more. These babies put my 15` cab in the ground. Big Bottom !!
Now this is what made my go for these , they can go VERY LOW,if you have a port on the cab it will bring out the bottom end lots & ive only just started to run them in, 3hours playing time so far.
Having a parametric eq helps because they do have a scoop at around 500-600 hz.Ive been putting my amps parametric on about 550 hz & giving them a boost & man they growl !! It took the store around 7 months to get them but it was worth it.

You cant put BP102` in a little crappy cab.They need a strong cab thats not too SMALL or BIG.I modeled my cabs after the Fender Pro cabs.
NO WINISD USED !!
They also dont need thousands of watts to pump.I use`em with a Fender TB-600 head & they have that much power that i drown the rest of the band i have to turn down .Who wants or needs high-end arent we bass players just a little is fine.Turn your treble up a little if needed. They have mids a little less highs but BIG lows (WoW).I also used a Fender BXR 200watt head which powers these babes with ease but need just a little more power than the average speaker, if you pump the power into them they just Growl even harder. Ohh Eminence did say the LEGEND BP102 would be great for me after i told them the dimensions & size the cabs would be. Use your ears to make the judgement its the best way.Dont listen to people that dont own or ever tried them... how would they know how its gonna sound.A cabinet design programme cant give you sound samples.
LEGEND BP102 ARE THE BEST !!!

cool. I´m building two 4x10" cabs (cloning the Hiwatt 410) and i´m gonna use 8x BP102. One of the cabs is ported and the other one is closed. I know these speakers are great and i´ll get the tone i want. I´m not gonna throw too much power into them (just 100W see my signature) but i know it´s gonna be ok.
Did you use a 2nd order filter just like they suggest on their page ?
post some pics !

See ya

Im not into all the techincal part of cab making thats why i copied the Fender Pro line cabinets to an extent. But instead of putting ports on front i put`em on the back right in the middle of each cabinet 1 port 4 inch wide. I get massive low-end if i want but usually have to dial back the bass cause theres so much of it but that brings out even more mids which is great.I can dial-in a nice midrange punch that has a growly thick tone to it.People say that the BP needs mid speakers or tweeters but i disagree because i get whatever i need out of`em .That high-end over 2k is too much for some including me, i dont like hiss at all. Theres heaps of guys on here that dont like tweeters on their cabs & its no wonder.
BP102`s are great`thick, bassy tone with heaps of midrange that i have to turn down some of the mids at times & as for the treble i have the knob on about 1`o`clock with top results.....what else can i say.Eminence told me that these were the ones & they are right. They have a very thick tone to them thats sounds like a piano, i love`em but thats my opion.Theres a few guys that hate them & i dont know how you could hate these speakers they bloody rip.
Keep Rockin Bassists.

Model the cabinet to be sure that you are not exceeding or approaching the mechanical limits of the driver with your available power. Otherwise your cabinet may sound very good until it no longer sounds good as your drivers have become damaged.

Your ears alone are insufficient for this.

Hi,
Yeah i know about that part of it & im just taking it easy with the BP`s for now. Ive had a few jams at medium level so im not pushing the speakers much.The limiter would kick in if there was anything going on in that area.
When i wrote to Eminence about `running-in` or `breaking-in` speakers they emailed back saying they have never heard of that before, it made me feel small like i asked a silly question & they also said speakers are meant to be played right off the bat but im still laying off the high levels for now ??????
Cheers Bass Heads.

My LDS cab was loaded with 4 BP102s. The cabinet was designed (tuned) around the speakers, though. It's front ported, along the entire bottom, and the port is pretty deep. It'll handle all the lows I could ever need, cleanly. I'm very happy with the sound I get from it.
 
#7
Not just for now. Eminence is right, breaking in a speaker gives almost negligable difference in performance and no difference in power handling.

Without knowing the tuning, I would derate the power handling of the speakers by 50% off of what is spec'd for a properly tuned cabinet. Yes, 50%.

When the limiter cuts in` is the amp at its peak or is it the speakers that are peaking ? I quess i wont be using the BXR with the BP rig anymore it doesnt have enough power for this rig` but the Fender TB-600 does.
They need a good amount of power to run forsure.I hadnt tried it at higher levels till yesterday & the limiter flashed a few times.
But what are you saying, what size cab do BP need to be tuned right in a 410 ? My cabs are pretty big & heavy with 4 inch ports, modeled loosely on Fender Pro line cabinets for size.How much more room do they need ?
 
#9
It's not only a matter of box size. The size and depth of the port matter, as well as the type and amount of insulation. Did you measure the port on the Fender cab? Do you have the same type and amount of dampening material? What about the Fender box's internals? What sort of bracing is there? Is the 410 built like Siamese 210s? All of these affect the tuning of the cabinet.

Hi,the ports are 4 inch wide no depth just a cut out right in the middle of each cab.If i add a tube in the port what will it change in sound, also the dampening material what will that do ?
The amp that i used the other day was only 200 watts (Fender BXR 200) its crap for power, it ran out of headroom quickly. I dont have a problem with the sound of the cab it sounds amazing but to get good volume they need more power... 200watts @ 4ohm just isnt enough to power 2` 800watt cabs @ 8ohm each.
Also i didnt try to copy the Fender cabs design i only got size dimensions.The ports are the same width as Fenders only i havent installed tubes for the ports yet, which is my next question.
How long should the Port Tubes be ? The cut out is 10cm wide or 4 inches, how long should the tube be ? What about dampening material, does it really matter, what will it do ?

I am going to suggest that you search a little bit on this subject, there is a lot that you are missing and I think a lottle good reading and researching will do you some real good. I would also suggest doing this before you damage your speaker.

The tuning of the SYSTEM is based on both the specific drivers used as well as the cabinet internal volume and the area and depth of the port. The system is modeled as a series of springs and masses and the tuning is critical to a reliable (and good sounding) system.

Cool ive been in touch with somebody on here who knows more than me & im going to make a few changes to my set-up.
Port size & depth are first on the list to try to get more low-end & tune the cabinet a little better, will be posting.
Cheers Andy.

Growly.. may i ask who you got in touch with ? i´m building two cabs and i´ll be using BP102s too... but i could be doing something wrong cos i´m not getting good results with Bassbox Pro and WinISD, and i´d like to talk to someone with more experience...
Do you think i could ask that person about my cabs ?
thanks

I better just ask him before i go ahead & do that but im sure he will help you.He seems to know alot about building cabs & is very helpful & sounds like a good person too.
Il give him your user name but im sure he has already seen your post.
Il be back.

Go ahead and PM me on this.

Note... I normally don't do this, but I think there might be some good opportunities for some folks here to learn a bit and expand their interest in learning more when they see WHY we (as professional designers) spend so much time and effort developing drivers and enclosures.

Once we get some results, I'll take a little time going through the hows and whys and tradeoffs in speaker design if there's any interest, using these as examples.
