Is BSW speaker upgrade worth it?

I figure if I get the midrange in good shape just using the onboard Hi/Lo filters of the XD600/6 I can add a subwoofer later and perhaps an EQ. In my past experience getting the deep bass was difficult and needed eq. I want to avoid having to put another electronic component in unless necessary. The advantage of the HiFi system is the full range, unEQ'd balanced differential signal delivered to the trunk mounted amp.
That said, I am a bit concerned in my simple system about bandpassing the underseat woofers. The XD600/6 seems to allow either Hi or Lo pass on a channel pair, but not both like a proper EQ would. My guess is that I will need to hi pass the 4 inch BSW's at 150-200. I can use the lo pass on the woofers to blend, but then have the concern that the woofers will not do a good job of mid bass if they are trying to push 35 HZ. I seem to remember that a tight, acoustic suspension enclosure creates a smooth sloped mechanical filter. That might work. |

So what about installing a set of 5 inchers in the doors, to bridge a little bit of that gap? The price difference is not significant between 4" and 5" and I have a feeling 5" will work in the front doors of an E90.

Otherwise you will need tuning tricks to try to move that band to a point of compromise. The XD amp does not have the necessary tuning selections to eliminate the compromise, it will be filter frequency and gains and nothing else. Either the SSMB8 or the ADMW9 will do as mid bass -from 50/60Hz to 200Hz and a trunk sub can take care of the 20Hz to 60/80Hz. IMO, VP Electricity trunk sub for the E90 and an ID10 will be more than fine filling that sub band. |

ADC,
If my planned BSW/Morels install doesn't work, changing to 5 inchers would, I guess, be an option. I'm kind of interested in doing this all for $1500. The Morels are probably "better" than the BSWs, but they preserve an "all Morel" option in the future and also, I believe, provide the best tradeoff between what I am looking for in these underseat woofers (I am careful not to call them subs). BTW, what lousy weather in our neighborhood! Still would like to get to Eastern shore. |

i have the 5.25" woofers from the MB Quart RUA213 setup installed in the doors
and i have them high passed at 60hz (12db filter) and i have my SWS-8i low passed at 60hz (24db filter) and my handoff from the MBQ to the SWS8 sounds great when i listen to any song now the bass feels like its coming out of the doors, seamless with my earlier setup, i was using the logic 7 4" in the doors i had to cross them over at 90-100hz (any lower and they distort) and my sws-8 were low passed at 60hz (any higher and they sound too boomy) i could feel the bass coming from under the chair, it didn't sound like it was coming from the doors. now my only problem is the magnets on the 5.25" speakers rub against the door window frame. they don't rub if i pull the door trim away from the door with my hand and they rub much worse when i tighten the screws that hold the door trim in place so next project is fitting some metal washers on those screws to give me a little extra clearance i believe the max depth on the E92 is 40mm, the MB's are 42mm so if it's just 2mm diff, i think a washer should cure that. i'm hoping the MS-8 i got today can help me tame the harshness that i'm guessing is between 3-5khz on the MBs |

The Rainbows I currently have (SLC 210.25 NG) are 48mm mounting depth, but the 230's are 58mm! I wonder if they'll fit... I'm thinking if I stay with Rainbows I would only need to install the mid, keeping the tweet and crossovers where they are - and this in turn would free the current 4" Rainbows to be installed in the rear deck (or sold).

kmarei,
Excellent info on your earlier results with the sws8i woofers. I think this reinforces my decision to go with the Morels and hope they can go higher. If they don't, I guess I can start cutting for 5's. |

you can play with the low pass crossover as much as you want it's easy to put it back where it is now cuz its set to the lowest setting on the knob, 60hz i live in reston, va about 5 min from dulles airport why would you want the underseat driver to play higher? why not get the door speaker to play lower? i can't see midbass coming from underneath you being a good thing |

low frequency extension or mounthing depth can't be fixed i believe the max depth on the E90 is 50mm so you're almost a cm too much we need to meet and compare notes |

Unlike some cars with an arm rest that may open to the trunk, my model has absolutely no connection between cabin and trunk. Would a trunk sub help? I know some say that the low frequencies will find their thumping way into the cabin, but what do you guys think? Any answer on the infinity basslink question? BSW's trunk sub is cool because of the hide away fibreglass enclosure. I wish I could just purchase that casing and put in my own sub and amp here. VP any link or pics of your trunk subs? But I guess that still won't solve the small problem of the hole in the mids right?

Install Questions
Technic, I am interested in the wiring harness you mentioned in your post of several months ago for the e90 with HiFi (base stereo) system. Is that available now?

There are some big helix 82dsp threads here with people using a variety of aftermarkets including the Jehnerts. The Bimmertech thread mentions them they have even developed a canned tune for them. Yeah you really do have OCD. I went through this to some extent when I was looking for an upgrade to. http://www.e90post.com/forums/showth...ght=bimmertech There are a bunch more threads like this if you search for Heliix 82dsp , bimmertech or Jehnert.
