I took out a woofer in the Bose B2 to show those who were interested to see what's inside. I hope someone can open and share what the inside of the F1 subwoofer looks like.
It's a good thing you shot this in portrait mode, we really hate all the annoying videos shot in landscape that create those irritating wide cinematic images our screens were made for.

The F1 Sub is powered, but the B1 and B2 bass modules from Bose don't require any processing, so they can be used with a conventional power amplifier in your PA system, and the B2 will have more wallop than an MB4 because it has about twice again the cone area again as an MB4. (The B1 is like half of an MB4.) I have put together a "Tiny PA" system with some 8" two-way main speakers, and two Bose B1s, driven by some Behringer NU1000DSP amps, and I dial in a 125Hz crossover and a 40 Hz HPF, and the B1s are good to go. (Why use B1s for PA bass? Because the whole thing has to fit into my car without being packed to the gills.) The bass character from the B1s is a little Bose-y (a little "boomier" than normal) but the amount of low end output for a tiny box is amazing.

The other chamber would have had the resistor network for the level switch. It's essentially just a sub box, 2 woofers and 3 resistors. That's why it needs a 4 core cable. 2 for the speakers and the other 2 just loop through the resistors to tell the amp which equalization to use.

Classic Bose philosophy: put two $30 drivers in a $50 enclosure and sell for $500. Great business model. Notice there are no specs on this sub ANYWHERE even the Bose site does not provide any.

Hi! Great video! My BOSE B1 speaker took a short fall and seemed to be working fine. Though no external damage when I plug my bass guitar in and hit a low note I here a rattle from inside. I took off the grill and everything seems tight in terms of the speakers, but I haven't removed them. Is there anything you can see inside that might rattle? Can I adjust the tension support bars I saw in your video? Do you know where I could get a service manual for this cabinet? Thanks so much!

Brett, Adding a 3rd B2 (imo) has very little improvement from 2. Once you have 4 B2's (and they are clustered together), that's when it seems there is a considerable amount of gain. I would say 4 B2's were around the same volume as a pair of QSC KW181's. The B2's are much easier carry and load in/out than the QSCs. I recently did a video as well opening the Bose F1 subwoofer. I shared my thoughts comparing it to the B2's.

When you double the number of speakers, you add only 6dB output. From the first B2 to the second, you obtained +6dB over one, but you would need four B2 to obtain the next +6dB, eight for the next +6dB, and so on. It's how decibels work (since they are based on logarithms).

rorybz Yes you are correct, though you only get 3db when doubling the power. The other 3db come from mutual coupling. So it's really important to have the subs clustered together. You'll have to purchase longer NL4 speaker cables to accomplish this with the L1 systems.

Cris had you have an issue with the switch on the b2, can you replace the switch of the b2 bass module?

you gotta try the f1s. I loved the B2s until I started using the F1s. The F1 has a lot more 50 hertz, but the B2 has a lot more 80 hertz. For DJ playback, F1, live, B2 is fine.

Not all of their products. You will love the Bose F1 model 812 top & Bose F1 subwoofer. I own 16 of them! Even 2 units cover up 7000+ sq ft venue barely at 50% volume! Rest of their products are junk! Ignore rest! Go for Bose F1 model 812!

Thanks for sharing this great info. I am curious. I am using 1 x L1 model 2 system with 2 x B2 bass modules. How much does the bass response change or differ, if I add a 3rd B2 module and a second A1 packlite amp? In your opinion, please.

Does B2 come out any voice like LFE or just the bass signal come out like Normal on the other home subwoofer? Because when I use QSC RMX 2450 drive B2 which come out like LFE include the voice of singer no matter I adjust any position from -, + or normal in the back of B2. Thanks in advance

Hi...!!! I have already all my Bose speakers for my home theatre, and I’m not sure which one select for my subwoofer, the b1 or the b2, one more thing you need to know, everyone I buy of this 2 models, I’m put 1 at left side and 1 at right side too. If you create same things, for power and deep bass, you select 2 b1 or 2 b2...??? Thanks

Have you had any problems with the B2 cutting out on you? I have an LI array with the B2. Owned it for 5 years and just recently the the B2 bass is cutting out at gigs. I can still hear my vocals and guitar through the Tower but the bass cuts out for about 5-10 seconds and then comes back on. I replaced the cable to the amp but it’s still doing it. Any help would be appreciated. Thanks

Drivers look pretty cheap too be honest. Absolutely no reason to be using foam surrounds at this price point. Paper cones are okay, not perfect but acceptable if made right. The magnets are not very big either.

Consider that this is a PA sub, not a home theater sub. Treated paper is the material of choice for PA applications, It's also not made for huge ammounts of power so there's no need for a super big magnet, although it's double stacked so it's not bad at all. For that price it falls in line with many other subs in this category
