Default What do you like?

I've been a lurking about among all the threads. Amps were easy and I feel comfortable with a chipamp kit like LM3875 or LM 4780. Speakers are a whole new game. I have not looked at audio for years but. the speaker market is just like it has always been with all sorts of claims, $ and little back up. A trip to various high end home theater vendors left me under whelmed. Would you really spend $20 k for a system? unreal.

I have a hobby cabinet shop that I can make most anything thing out of wood. Happy to post a pic if there are any other wood guys out there. I want to make a nice system for the shop with decent bass and minimum distortion. My old ears are not golden but don't like distortion. Right now my speakers are very old AR2's bought new so long ago I'm embarrassed. Sort of like listening to music with mastic/velvet as a filter. They served me well in the shop for many years so shouldn't complain.

Years ago the speaker choices were the same as now. I thought by now it would be sorted out a bit but found the same old claims. The trend seems to be smaller because of apartment and condo living. I have no neighbors except for the Wifey up stairs from the basement.so big is just fine with me, The shop is about 2000 sq feet with a cement floor. Right now the speakers are in the machine area on a wall but could be anywhere. Dust is not a problem with central dust control.

I just have to build these my self ,just because. I'm a DIY builder of all things.No options here.. Any recommendations of plan sellers and that have been well received I would like to check out. I like radical ideas and complex I love. So sealed,ported, folded etc are up for grabs.

Appreciate your help folks, thanks.

>>> What do you like?

Music!

Go for a back loaded horn and enjoy! I had AR15 and my parents still have AR92... I always enjoyed the AR sound. Many of the DIY projects on this forum will sound WONDERFUL and much better than the ARs you currently have.

PS, you said complicated so my recommendation is back loaded horns... but I also love open baffle speakers (but they are very easy to build).

You've got lots of room to fill with bass. If you're going with a full-ranger, I'd say go OB. Full ranger of choice, couple or four big woofers, bi-amp with MiniDSP, add amps to taste.

Otherwise I'd go to the multi-way forum and think about horn systems.

As a challenge try some folded Voight TQWP speakers.

Yes, that's a lot of space. I suggest what I call an FRA
Full
Range
Assisted

A 3" full range mated to at least a 12" woofer for that kind of space.
That way you can have a low crossover without any lobing issues. (good polar response)

Here is one I designed for someone here.
Thank you "Melo theory"....

Assuming a construction challenge is what is desired, a large back-horn is going to be the most challenging thing out there for unsupported wideband drive units. Otherwise, I suggest a multiway design of some kind, or possibly a line array.

@Scottmoose, no ad, just showing a picture of my speakers (if you looked at the Views link). Without knowing the room dimensions it's difficult to suggest something, especially if the room is full of machinery. The TQWP's are great sounding especially when using corner horn loading and require some woodwork ability to construct - mine especially.

Yes a line array. Good call. I think that is what is best for this situation.

Think I'd go with one of those Eminence dual-cone 12"ers, give it a suitable tweeter and a big ported cabinet. Say, 70-80L, tuned ~40Hz. Apply damping to taste.

It wouldn't be much of a challenge, construction-wise, but I'd expect it to annihilate any single driver in a BLH when it comes to filling that space.

You could even go 2.5-way and add another 12" bass driver if one per side is found lacking.

Since you have the space, google for the Cornscala kit, especially the two way variant. I expect it to be awesome in your shop. It gets universally great feedback.
