Subwoofer to accompany Mackie SRM450s?

[jkowtko]

For our next production, Music Man, for the first time we are using a pre-recorded orchestra in a musical. I would like to "play" the orchestra as realistically as possible.

Our theater is like a flex theater -- no pit, floor level stage, and we usually place the band in, under, or behind the set. For this production I plan to set up a separate set of speakers behind the stage on stands to play the band, and these speakers will be separate from the FOH speakers where I will pipe all of the mic output.

My budget is (as usual) limited. Since we have a bunch of SRM450s for the house, for future flexibility I bought another pair of SRM450s with some stands to use for the band speakers. However with a 45'x65' 175 seat house I'm thinking I'll need subwoofer support.

Since the SRM450s are self powered I'd like to stay with self-powered subs. I'm looking at used Mackie SWA1501 and SWA1801 in the $500-900 range.

Any suggestions or recommendations between these two subs, or any other brands I should look at for that size of room?

Thanks. John

Stick with those options. I'd go for the 18" ones, if you can afford it, they'll give you a nice response. I've seen and heard that combo (mackie SRM450 w/ mackie SWA1801) a few times, and it's a nice setup.

Beware, I've heard many more horror stories about the Mackie 18" subs. I think there was a run where the cabs weren't sealed well, and would either fart, or shred the cones. I don't have a problem with the 15", but if you used them, you would definitly want to cluster them.

Why not rent some powered subs for this performance, then wait and save up for some top quality ones? As an alternative to the Mackies, you might want to look at Yorkville. I've heard good things about the UCS1P. It's a horn loaded 15", so you'll have to group two or more to get really good bass. I've also heard good things about Danely Sound Labs subwoofers.

I've already looked into rentals ... seems nobody wants to do long-term rental since their equipment is in good demand for short-term ... they charge roughly $50/day per major component. We need the equipment for six weeks, (tech plus five weekends of performances), and I'm not about to cart 100+lb subs back and forth to the rental counter every Sunday and Thursday, so at full value we're talking ... ouch! Even with a heavy rental discount it's still far worth it to buy some equipment, use it, then sell it afterwards and even lose a bit of money in the turnaround.

I will check out Yorkville and Danley Sound (thanks ... fyi the Danley looks like it is the same as the Yorkville) ... can you tell me how strong those should be in comparison to the SWA1801?

And as usual I'm concerned about mix-matching brands for something like this, so if someone out there has had success with non-Mackie subs on SRM450s, I'd be very curious to know. And I guess if I can find a good deal on a used one, at worst case I don't like it I can resell it ... (provided I buy and sell locally).

Thanks. John

There are a lot of people who like the yorkies and Danley subs (prosoundweb has a whole section on the sub project that they did)
Two U15p and two UCS1p would be a great system you could look at http://www.musiciansbuy.com/yorkville_unity_series.html
and ask them for pricing on the UCS1p I only see pricing on the un powered one,

Personally with Yorkies this is the line I would go with, Tom is something of a genius, stuff is great, but you are probably looking at almost two thousand dollars more for the system. Would you have a better system than the Mackies, for sure

To expand a bit, typically if we are asked to recommend a simple but reasonable quality starter system for say a church or small venue where the main function is voice reinforcement, we go with the Mackie srm450. Once the client wants to upgrade for music then it comes to decision time. Usually if the have the budget, we move the Mackies to being powered monitors, and then go with a system along the lines of the Yorkie unity and up. Obviously sometimes the money simply is not there, and then we usually recommend the 1801. The 15 version unless you get two and stack them really IMO doesnt add enough sub.

One thing that does not work with the Mackie SRM 450 is to try to use two of them on each side, the horns and dispersion patterns do not work well next to one another.(splayed)

The yorkies Unity will work well stacked and splayed.

You could use the Yorkie sub, would probably need to be turn it down a bit, personally I think using the full Yorkie system would be far better

No matter what you go with, try it before you buy it. Rent a Mackie, and mabey the Yorki for at least a day and try them out in your space, just to see if you like the sound. The only reason I suggested the Yorkies was that I have heard of people who's 1801's have shredded themselves because of the construction of the cabinet. Personally, I think they sound too flappy for a sub. I prefer the 1501 sound, but realize that it may not be perfect for your use. Just food for thought.

Take a look at the EV SbA760, it's a bit more than you've budgeted but an excellent performer.

[jkowtko]

Thanks for the input everyone -- a lot of good ideas to check out.

Since I already have the Mackie SRM450s I am inclined to try to stick with Mackie for now -- provided the sub sounds okay. Fortunately I have two options for purchasing the 1801 at a decent price, and in both cases I should be able to test it in the theater to see if it sounds muddy or not (I definitely do NOT want muddy bass). I need orchestral drums and bass primarily, not rock or disco, so I am looking for a smooth but firm low end response.

The EV is a little pricey, and I thought they were in the realm of Peavey, etc, rock speakers that don't generally have flat response?

The Yorkville appears to be well respected overall .. I wish I had a little more money to spend so I could by the full range speakers to complete it. Since the local shop also carries Yorkville I'll see if they have a UCS1p I can look at.

The local store also has a JBL PRX518S at $100 cheaper than the 1801 ... any comments on this speaker? I'm thinking for such a small price difference unless the JBL sounded a lot better I'd still go with the Mackie.

Thanks. John

On paper the JBL looks good. Try it and see. The PRX's are new products, and I haven't had a chance to hear them yet. Looks like it's built-in amp is based off the Crown I-Tech, giving you DSP functions built-in, that is if Crown has resolved the issues with the I-Techs and XTi amps. Try it out. Tell us how it is.

On the budget side, does anyone have experience with Samson, JBL or Yamaha active subs?

- Samson db1500a, db1800a
- JBL jrx118sp
- Yamaha msr800w

Some of these can be obtained demo or used for well under $500, which means two for less than the price of a single Mackie or Yorkville. If anyone has good or bad things to say about any of these it will help me as I scout around for next next couple of weeks before I am forced to make a decision.

Thanks. John
