Good morning. I am new to bfm speaker building forum. I have some experience in diy. I've built some diy soundgroup speakers and my most recent was the lx521s from Siegfried linkwitz. I am bit by the bug and enjoy the building process as a hobby. So, my next project is going to be the tlah pros for my future dedicated home cinema. So I bought the plans and I'm ready to begin cutting. I'm planning on using 1/2 inch mdf as it is much cheaper. My initial question is after looking over the build plans can the speaker be built with the speaker flipped, so the 5 inch top becomes the bottom? From what I understand the 3 inch end is not sealed. It would be easier to screw a base on the 5 inch end so it's not so tipsy. Will this change performance in any way?

If this can be done I thought I would build the wider end a couple inches longer and then apply a base to that extra mdf. Thanks for the help, I look forward to your responses.

Build it like the plans say or don't build it at all.

Will do. Thanks for the friendly reply.

Welcome to the forum!

How big is your room? TLAHPros are intended for larger rooms, and used as a PA speaker. The regular TLAHs are plenty for a living room /HT room.

In regards to the base, it's in the plans on how to make it a floor-stander.

Indeed welcome to the forum

Jimbo's response may seem a bit harsh, but you'd be amazed at how many people come here and say something similar to you for X design.

While it's in the plans for HT designs, MDF sucks on so many levels. Cutting it, weight, hates water, blah blah blah lol.

Sure, it's DIY, and you can do what you want, but the cabs work best when built as described. You can get what you expect, and so on.

Tom has offered up the floor stander adaptation, maybe something else we can say might help too...

Thanks for the replys I appreciate it. I am going to build them by the specs exactly. My home theater is going to be 20x28 with 8 foot 7 inch ceilings. I'm totally into over kill, so I'm good with the pros. Actually got started yesterday. One cab almost done. I'm building out of mdf, which yes totally sucks to work with. I may rebuild them at some point out of ply. Again, thanks for posting the help. I will post some pics after they are done.

Good morning. What do most people use for center speaker and surrounds? I will be putting these speakers behind a transparent screen. I have seen that the best bet for center speaker would be another tlah pro. Is that correct? The curved sla is really cool looking. The other thing I was wondering is what do most people use for the surround speakers? Is it one of the slas? I'm sure it's all on the forum somewhere, but I couldn't seem to find it. Thanks in advance.

The curved SLA is a compromise that gives good horizontal dispersion despite being horizontal. If you have an acoustically transparent screen then use a vertical speaker.

Hello. Thanks for all your help up to this point I appreciate it. I have one speaker built and I am at the point to build the mounting. On the plans it shows how to build the pole mounts on the speaker, but I was wondering what u use as a base for the pole. I thought of an umbrella base, but not sure. I thought maybe some of u would have ideas for that. Thank u again.

Jim

Pole mounts are for portable PA use, with PA stands like these:

I doubt you'd want that for home theater.

I see now how that works. Boy the simplest ideas sometimes slip by me. Thanks bill.

If I dont use mounts for lcr I'm curious how a person would stand these speakers up since they are rather tipsy. Any suggestions on how others here on the forum have done it would be welcome.
Thanks

Those I've seen in permanent installs were wall hung.

.. usually with french cleats.

Hello. First of all thanks for everyone who has responded to help this far. I have finished my two tlah pros. I received my crossovers today. I looked on the forum for an answer, but had no luck. I am very much a novice at the x over etc... part of the speaker building process.

So now I am at the point of hooking everything up. I am mainly building these for home cinema. What would be the best configuration hook up for woofer, tweeter speaker? The other thing is can these be hooked up to an avr or do I need a pre pro with amps? Like I said I am a novice at this part and very limited knowledge. Any advice would be fantastic. Thanks!
