Compact with Packlite + B1

there is a simple in line lo pass crossover you can buy from parts express for $15 or so. I tried this coming out of the back of the compact into the Pac-Lite, and it was OKAY, it needed more gain on the output to keep up with the compact, +lot's of phasing since the 8" woofer already there as that was not crossed over

4"h X 5.5"w X 11"d. Just add B1s and cables and there's a solid little bass package with super quick set-up.



Hi Dj Richard where can I order a Rolls Crossover here in NZ? I tried different sites but they don't supply it. Thanks in advance.
One thing I did for a little while when I did a weekly karaoke gig at a little bar was... I used single Compact with a 1/4" from the line out to my second Compact with the line array out. Not any more lows, just more of the same bass. +BTW I would keep the second Compact very close to the base of the other (touching).
I checked it out but it's a rack gear too. I really like the size of the Rolls Tiny crossover so I can just put it next to my packlite discretely. Thanks for the reply.

Hi Exodus, I bought my Rolls Crossover from Amazon.com. There's a stereo crossover at The Rockshop which looks interesting, has a sub output and which isn't too expensive. If I read correctly, that would be quite funky for a pair of Compacts, a Packlite and a B1 or B2.
Hi DJ Richard,

I did exactly what you said and created a YouShop account and ordered the Rolls SX21 Tiny Crossover from Amazon for US$67.00. It's on the way to NZ and apparently arriving next week. Can't wait. I'll keep you guys posted. Thanks again DJ Richard for the tip. Nick, I think you should go for it too.

Nick & Exodus, here's the link to the Rolls SX-21 Crossover at Amazon. This retailer doesn't ship to New Zealand, but you can set up a NZ Post YouShop account and that gives you a USA address for deliveries. That's how I got my DJ mixing desk and last pair of running shoes.
I have been kicking this around for some time. I just recently injured my back, so I sold both the powered subs I have. I just recently scored a Packlite on eBay. Why not come out of the main out of the Compact into the Rolls, than into the Packlite/B1 or B2? Also, have seen some newer model powered subs that look intriguing. The Fender PS512 and EV makes a similar sized powere sub. They come in about the same sized specs as the B2.
Hi macheted01,

I'm sorry to hear about your back. I hope feel better soon. In the meantime, take extra care. Congratulations on getting the A1 PackLite.

Yes - you can take a line out of the Compact Line Out to a crossover (like the Rolls) and from there to the A1 Packlite and B1 or B2. DrumrPete posted his report:

Mic'ing Kick drum with L1 Compact, Rolls SX21 tiny crossover, and Bose Ext. Bass Pkg.

I hope that helps.

I just can't get enough bass (I am a drummer, so that could explain it) so for what it's worth, I just bought the Roll's SX21 and a Packlite for use with my Compact and a pair of B1's I had and I LIKE it   I have become a Bose devotee !!!  Oh, I was messing around and thought I would just play some music through it using the RCA's and just used the line out of the Compact into the SX21 (didn't use the T1) made for a lot cleaner setup ONLY 3 outlets  and added nice bass YES probably to much bass for most but ...... 

I'm a very recent L1 Compact owner and so far really loving it! Sounds great with the prerecorded music playback we've been throwing at it and my wife is very pleased as well which is always good

For my own preference, I'd like to be able to add more punch to the bass which is why I'm looking at taking the same approach of adding an outboard crossover, Packlite, and B1 to use with it.

Can anyone contrast this option against other approaches such as using a powered subwoofer? I'm looking at the Behringer B1200 as one option. Part of me likes the idea of using the Packlite + B1, but another part would prefer a simpler approach where the sub would have an integral crossover and involve fewer boxes. It's a tradeoff. Not sure of the quality of that unit, but it's a lot less expensive and more compact.

At this point I already have hooked up a Bluetooth audio receiver + power adapter cabled to it, not wanting to add too much more outboard stuff but would like more bass.

I guess I could have chosen a different system that included Bluetooth and had more oomph, but in actuality the ones I tested didn't sound as nice as the Bose.

Wondering if anyone has an opinion on the various options available today vs when this thread was first posted?

HI mitsurugi,

Thank you for joining the Community.

If you're looking for more bass, have you tried putting it in a corner?

Please tell us how you are using your L1® Compact? Is this for DJ applications, private parties in the home, something else?

Thanks,

ST

Hi ST,

I haven't tried a corner placement yet, just against a wall. My living room area doesn't have a suitable final resting place in a corner where I could tuck it all the way back into though. I will give that a try after I rearrange some furniture.

I temporarily connected my surround sound subwoofer to the full range outs on the back (it has a builtin crossover) and even that, though limited to 50 watts, puts a noticeable oomph in the kick and adds a fuller bottom. It certainly puts out more of a low end punch / thump. 

My most immediate reason for purchase was to provide a reasonably well performing and visually appealing source for music at my son's graduation party and other similar family get togethers. I had considered a couple of 10" powered PA speakers plus sub and speaker stands, but I ruled that out for simplicity & portability.

Secondarily we don't have a home stereo system anymore having migrated to all Mac and PC based music playback. We'd lost our speakers as casualties to animals and children some while back. So this will most likely stay somewhere in our main living area as it's so much better than my former PC speakers I'd used in our living area to play music from our Mac

Another use might be for karaoke, but at the moment we have a dedicated amp and non-powered speakers for that. Not very happy with their look so this might get used for that purpose.

The most unlikely use is for live music. I play bass and sometimes guitar so if there comes a need for a portable PA for a small get together, I have an option for that.

That covers the main uses, I think!

 

I now have a pair of Compacts and have paired them with a powered JBL 15" sub - a Packlite and Rolls SX with 1 & 2 B1's, the Packlite with a B2, a QSC K12 Sub and a 12" Dennon Axis sub,  with a single Compact 1 or 2 B1's gives me what I want.  I must say I am more impressed with Bose every time I use mine and I still am amazed at the bass the B1 produces.  With a pair the JBL sounded pretty good but 90% of the listeners out there will never know what is missing if you don't have it and will still be amazed by the sound produced by the Compacts.  I was using an L1 S1 the other night DJ'ing with a B2 against a wall and I actually had to much bass ........  

 

I'm still noodling this around myself. There is another thought I had:

Is the B1 designed such that it only performs well when it is driven from an L1 having the built-in "B1 EQ" settings? IOW can it do well on its own, or does it need special EQ settings to bring out the best in it, similar to the 802 PA speakers?

Yes. There's a crossover and EQ profile in the L1® power stand for the B1. This is not present in an L1® Compact. The L1® Compact Line OUT is full range.  This is why you need a crossover to use a B1 with an L1® Compact.

IOW can it do well on its own, or does it need special EQ settings to bring out the best in it, similar to the 802 PA speakers?

Tom,

 

Did you find the pair of B1s sounded better and was louder than the Ksub and JBL sub, and what model is that?

The B1's do not create the same bass response as a KSub - The B2 is similar but the B1's have their own sound,  it is tighter and run through the Bose T1 Tonematch or into the Compact I find I like the sound of my cajon and electronic kit (Roland TD and Yamaha DTX12) better, they sound great with very little fiddling and I have to work to get the same sound from my other subs.  The JBL is aJBL PRX715XLF 15" and a great sub but the ease of use of a pair of B1's or the B2 is now causing my to choose them over it.

 

Hi ST,

Sorry for not being clear on what I was asking about

Yep, I'm aware that I'd need a crossover when using an external sub (either the B1 or other).  But what I am curious about is whether the B1 itself needs further electronic massaging to "sound good"?

If you think about some Bose systems - I'm imagining a set of 802 or 901s where you are never supposed to go without the special equalizer - the question comes to my mind regarding just what exactly the L1 is doing internally when it routes the signal to the B1.

I am making an assumption that because the L1 tower has hardwired internal support for the B1, there's a likely potential that the L1 actually includes special Bose-unique processing to make the B1 come alive. If so, obviously I would not get the benefit of that when using "just" a crossover. Do you know if that's the case? (Hopefully that makes sense!)

Thanks! Ya, I don't care for the Ksub, although louder than B2 and of course a pair of B1s.

 

I do however think the PRX 715XLF is a better sub than the B2, but not as portable.

There is definitely some B1 specific EQ processing inside the L1® Model 1S, and L1® Model II.  That's not present in the L1® Compact.

You are right, you won't get the benefit of the Bose-unique processing (EQ) if you use "just" a crossover.  It would be difficult to replicate that because:

  • the B1 was designed to work with the larger L1® models. Those units have a crossover point at 200 Hz
  • the L1® Compact goes down to 65 Hz
    • You will have some overlap with the B1 unless you set the crossover at 65 Hz 
    • You can eliminate the overlap with the crossover at 65 Hz, but then you're only getting the range from 40-65 Hz from the B1
  • The Bose-unique processing for the B1 and the sound the designers were crafting was based on the B1 running 40-200 Hz.


That doesn't mean that the B1 with a Compact can't sound good. It just means that the designers didn't anticipate this use case.

Does that help?

ST

 

I have used the Compact with external full range speakers, house systems, and with powered subs. 

To my ear, the full range systems and powered speakers carry a very similar eq to the Compact, I am always pleasantly surprised with the sound I get in those instances. It seems that whatever is going on with the Compact eq is present in the line out.

Let me offer an opinion on sub use based on recent personal use with the desired output being limited to producing a bass drum thump with an electronic foot drum, to accompany an acoustic guitar and male vocal.

I have used two different powered subs, one expensive, and one not so, both 12". With the crossover at 150 Hz and the output volume matched to the Compact, the eq of the sub was not a factor. The bottom end is extended to 35 or 40 Hz and the overlap does not muddy up the sound in a detrimental way. Cost of the sub did not make a noticeable difference in sound.

If the music being played is heavy in bass content, then that overlap could become problematic and require a variable crossover to minimize the overlap region. 

Because in my experience, I didn't think it necessary to run the subs at full power, the only issue I see with using the B1 with a Packlite is you have no volume control, unless, of course, there is one on your chosen crossover. Depending on your needs or desired bass response it might not be an issue at all.
