My first pro audio build, church sanctuary speakers

Post by mattsk8 » Mon Apr 08, 2013 12:13 am

The design is from Bill Fitzmaurice, he calls it the TLAH Pro. I got a bunch of wood cut over the weekend. Tomorrow eve I hope to get drivers all wired up and mounted. Once this is done, I'm going to take one of the speakers to Meniscus so they can test it. The plans don't call for a cross over at all on the woofer, and I'm scheptical about that. Also a little scheptical about the lack of depth on the cabinet. This design came highly recommended on Bill's forum, so I decided to forge ahead, knowing close to nothing about pro audio :? !

They're 6' tall and use 8" Eminence woofers, w/ some super cheapo china piezo tweeters ($2.00 each!).

A pic of the inside. I rabbeted and dado'd all the joints, except the little blocks for the woofers, those are just glued and pinned in.

All clamped up.

Waiting till tomorrow to finish installing drivers.

I got these all wired up last night, was up till 2am. About 25' of wire in the cabinet!

Because it was so late I didn't really have time to whale on these. I will say they're SUPER sensitive! Next to my garage speakers (the Tritrix, which aren't very sensitive at all) I have to move my balance knob over 3/4 towards the Tritrix to get the same volume. Another first impression is, HOLY MIDRANGE!!! I don't know much about pro audio at all, but IMO the tweeters are way too quiet.

That's just a first impression, and I only listened for a couple minutes. It always takes me a bit to warm up to any new speaker, regardless of whether it's good or bad sounding. Tonight I'll get down and dirty w/ them, sorry neighbors!

I'll be bringing these over to you guys at Meniscus tomorrow morning. Can't wait to hear back on what you guys find w/ your measurements!!

very very nice.

very clean, i enjoy the work you do. i havent made the jump to festool yet. you think its worth it? unless i was in a hospital or a lab doing solid surface counter tops or work where inlay is everything i just cant see myself justifying it. although everytime i do i use something of theirs i think to myself "wow i have to get this"

Thanks for all the kind remarks! Its definitely a learning experience for sure! I really appreciate Meniscus' work in this. Chad has measured the speakers and so far it looks promising. The sactuary is octagon so nothing short of multiple speakers will be ideal, but so far it seems these will suffice. I plan on doing a pair of subs to compliment them as well.

I did get a chance to play these before dropping them off to Meniscus for measuring, WOW are these ever LOUD! Hooked to my 85w/ch Kenwood garage receiver and playing TSO's Carmina Burana I'm pretty sure I hit Motorhead concert SPL w/ just one of these! Surprised the cops didn't show up :lol: .

As far as Festool goes, it kind of depends on how much you do woodworking. I have 3 sanders, the track saw, and the dust collector. The sander w/ the dust collector ALMOST makes sanding fun! It literally takes all the dust out of it. The dust collector w/ the track saw is fairly dust free as well, which is really nice when working w/ MDF.

As far as whether or not they're worth it, they are expensive. I LOVE my track saw and I'm VERY glad I bought it, I think that's worth every penny. When used in addition to a portable table saw, for me it eliminates the need for a huge expensive cabinet saw; plus it's thousands of other uses.

If I had it to do over again, I would only have 2 of the sanders and of the 2 I would have the RO90 is my favorite just because it's so versitile. I also have the RO150 which is a fantastic sander as well, but if I had to pick one favorite it would be the smaller RO90. I also have the ETS150 for finish sanding, but I purchased the RO150 after that and might sell my ETS150 now just because I use my RO150 and it basically does the same thing, but much more as well.

So to answer the question of whether or not they're worth it, to me they are. They hold their resale value incredibly well. I can probably get 75% of their retail for them used. They're engineered fantastically well, and the dust collection is second to none. It is a tough price to stomach at first though, I was a cabinet maker so I made my living w/ them. Before I had Festool, I did manage quite well w/ my Rigid and Dewalt sanders, but the Festool just makes it a little bit better ;)

If you're a carpenter then you can't go wrong w/ the Festool TS55 (or TS75, I have the 55) track saw; buy it and don't look back! Depending on what kind of carpentry you do, their sanders are very nice as well; a worth while investment if that's how you make your living. The dust collection is fantastic. Be warned though, once you get a taste of the green koolaide, its a downward spiral :lol:

do you find yourself needing a belt sander or does the ro90/150 take the place of one as well?

That's actually a great question! I bought my RO150 to replace the use of my belt sander. I make my veneer w/ a resaw and planer at 1/4" thickness (or less, depends on the wood). I used to belt sand it after I glued it down to smooth it out, but it was tough to get consistency. The RO150 is FANTASTIC for this! It cuts as quick as a belt sander but is almost perfectly flat (I use the hard sanding pad on the RO150). It gives me very sharp edges and works better than I ever imagined, I'll even say it cuts faster than my belt sander did, but soooooo much better finish. Couple that w/ the RO150's ability to finish sand as well, and it's win-win IMO.

I wouldn't say the RO90 would be a good choice for this. Its more for detail work and smaller work areas. The 90 is the only sander w/ the triangle pad I've ever used that actually works. Then you also get the small hard cut, round 3" pad (nice for cabinet doors or face frames), plus the using it in finish mode w/ the 3" pad for additional detail work.

The dust collection from both sanders is amazing, sanding MDF there's virtually no dust.

You definitely sound like you know what you're doing and you would gain from these. I know the price is tough to stomach, but the quality is worth it, especially if thats how you make a living. I think the tools pay for themselves in quality and time saved. Be warned, once you take the initial plunge, all of a sudden all your other tools are obsolete so it can be an expensive venture!!!

Update...

Been a while since I've said anything about these but I have been picking away at them. After a lot of deliberating, I decided to go w/ a single, Eminence tweeter over the array of cheap piezo tweeters and man am I ever glad I did. Sounds WAY better!!

Blurry cel pic. Guess which one is the new upgraded tweeter :D

Image

Made some grill frames that I'm having Meniscus wrap, I hate wrapping grills!!

Image

The grills get screwed to the cabinets and they're spaced about 3/8" between the front of the cabinet and the grill.

Image

I was going for a pro-audio look, so I had a friend of mine that owns a truck accessories shop spray these w/ spray on bedliner. They came out rougher than I wanted, but I still think they look good (just a little different than I anticipated). The nice thing is, I could probably pitch these off my roof and into my driveway and they wouldn't get a scratch :lol: They're a bit dusty in the pics. Before I send them off I'll clean them up. Once these are done w/ grills attached and in the church, I'll post some good resolution pics.

Sorry if this was already mentioned but what size space will these be in? They look great BTW!! Are they specifically for voice?

Probably 80% of what goes through these is voice, but they're not specifically for voice. I also plan on building a pair of BFM horn loaded subs to go w/ them, but the church needs to build up the budget to get the amp and drivers for that build. These definitely need subs.

The area is an acoustical nightmare. Its all concrete block construction, and its an octagon shaped room w/ 30' tall, vaulted knotty pine ceilings. Here's pics of the church. The speakers will get flown (not by me, but my cabinet mounting points are rock solid) above the clear podium in the middle on the stage.

Going back through this I realized I never posted finished pics or results :oops: .

I'm very pleased with how these turned out. I'm very glad we swapped the tweeters from the original design, the originals were awful and the new tweeter implements well in the array (thank you Meniscus for your help with that).

My goal was to have plenty of headroom, and this design in this atmosphere is a home run IMO, it's VERY loud if you want it to be 8-) . SQ is very realistic, and the array broadcasts very evenly in a difficult venue to implement a sound system in. Now I need to teach the sound board guys how to work it, a few Sundays have been too loud, and they need to settle down with the high frequencies when they're dialing in the microphones :o :) .

Next up will be acoustic tile for the center of the ceiling, and a pair of BFM design horn loaded 15" subs (these definitely need subs).

Once again, very happy with the way these turned out, as are the other members at church!!

Pic of them flown...

Just knowing you were cutting that many holes makes me shed a tear for you! They are lucky to have you.
