My parents have been looking at a 48" sound bar to go under their new flat panel TV. From what I understand you can connect your LCR channels to it. They are interested in having me build them a DIY version. As my amateur audio mind starts to think thought the project - having LCR channels that close together would create cancelation and a pretty 'messy' HT front sound stage. Has anyone experimented with this type of set up? My parents are far more into ascetics then they into having their 'big' speakers in the room which are some two-ways on stands. Has anyone heard any of these that they can comment on? They model they were looking at was close to $400. I wandered how the Dayton BS36 sounds over at Parts Express for around $169?

To recreate the soundfield there's a ton of DSP occurring in these things. So realistically they probably aren't a DIY project unless you're a programmer with the ability to create your own custom chips.

I would personally opt for a conventional speaker design. Soundbars just feel wrong to me. Consider L+R with this design and just add a small sub. For the centre channel you can modify the enclosure slightly if need be.

Thomas,
I imagine any "soundbar" selling for only $400 is simply 3 passive LCR type speakers in a single enclosure. In other words, the units that have all the built-in DSP stuff are 2-3x that cost.
Here's the Dayton unit that the OP referenced:

Looks like Dr Hsu created a comb-filtering nightmare.....
Might work better if there were damping material on the baffle to function as waveguides.
From design to plugging in it would cost more than $169 to DIY something like that.
IMO he'd be better off building something like this and run a mono signal...

I think the Seas coax would be a nice option for a bar-type LR or LCR. I use these in a Rick Craig designed speaker, and like them very much. Zaph just measured them too.
Since everything is so close together, you may want to consider a phantom center with LR only ala the Theil Viewpoint.

How about something like this, with or without the center channel. Use pairs of 3-4" semi full range drivers, like the Dayton RS100, paired with a neo tweeter, like the Vifa D26nc55. Run them sealed and cross them over to a small sub at 120hz or so.Attached FilesDan N.Comment

How about aiming the L/R speakers away from the center channel, therefore beaming the sound off to the sides?Comment

My question is as my folks have a Sony BDP-BX37 and I believe it will only do bit stream with HDMI. (Also as this is my 85-year-old parents set with a 42" LG LED LCD TV that has only one opt dig output that then would go to the sound bar of my choice.) With all I have read and gone out and auditioned...28 January 2011, 13:47 Friday -
Hi all,
I've been playing around with one of my designs (the Monoliths): a 2.5 way with Peerless 830884 drivers and a SEAS 27TBFC on top. My parents have them, and they asked for a bit more top end sparkle (I assume due to their hearing loss).
Anyway, after further refining... -
I've been working on a few Group Buys at some of the other forums dealing with waveguides, MFW subwoofers, JBL gear, and a few other things. One was for a flat pack kit for the Anarchy tapped horn on AVS and then the Overnight Sensations from PE.
As with the other Group Buys I helped... -
The purpose of this thread is to review the idea of how difficult it is to maintain precision with completed DIY designs, or any speaker for that matter, over a long period of time. A lot of the designs on the web are getting pretty old now, including even some of the Mission Accomplished speakers.... -
I'm new around here. I've been reading your posts relating to DIY speakers. Based on those, I think my questions should be cake for you guys. I am using Bassbox 6 Pro to design speakers for my new HT. I've built 3 or 4 speaker systems in the past. The first pair, in 1980 or so using drivers from a...
