BIC FH6-LCR Horn Tweeter Mod / Review of the DV-62si

post #1 of 13
Thread Starter 
So i got my FH6-LCR in and right off the bat i knew the horn was set up for standing vertically. This way the horn would fire wide when standing upright. I just wanted to showcase a simple mod for those who wish to use it as a center channel speaker as most do. I simply took out the horn tweeter and rotated 90 degrees, this way it will fire wide when on its side. All of the screws matched up when it was turned so its very simple to do. See pictures.

Quick review on the FH6-LCR:
Construction: cabinet is thick MDF, Polyfill throughout, crossover board is of modern circuitry, large magnets, rugged construction, very nice woofer material.

Sound: Sounds fantastic but still needs its break in period as did the DV-62si's (just got it). Zero distortion at high volumes, much clearer dialog makes for a considerably more enjoyable experience. Loud, had to turn down the center to balance.





And now with horn flipped:



Specs:
Design: 175-watt two-way 3 driver All-Channel Speaker. Wall mounts included.
Frequency Response: 40Hz-23kHz
Sensitivity: 95dB @ 1 watt, 1 meter, high efficiency output to 116 dB
Drivers: Dual 6 1/2" injection-molded woofers, one 6 1/2" mid/high frequency aluminum dome horn tweeter with Neodynium magnet.
Magnetic Shielding: YES
Gold-Plated Terminals:YES
Recommended Power: 10-175 watts per channel
Impedance: 8 ohms
Dimensions: 6 1/8"D x 21 7/8"W x 8" H
Weight: 25 Pounds each
Warranty: 5 Year Parts & Labor

This is going to be a short review of the DV-62si. The reason i am doing this is because after taking it apart i noticed that there were several design changes, tho i didnt take any pics at the time.

Construction: First: they now have polyfill throughout! this is new, and unexpected because i had bought some cheap polyfill pillows to murder / fill the speakers with and now im stuck with 2 pillows! the crossover is different than other opened DV-62si that i have seen and seems to be of updated circuitry (maybe taking into consideration the crossover mod), and finally they have braced the cabinet made of MDF with triangular shaped pieces in the corners. This company have listened to their customers and delivered, i was quite impressed.
I am selling 2 pillows, PM me lol.

Sound: Excellent, actually blown away for 100 bucks. After they broke in (30hrs or so) I had some friends over to test the system playing high quality audio files; for fun i shut off all the fronts channels and just ran the 4 DV-62's plus 3 subs without telling them. They had no idea it was just the rear channels and were amazed at the sound! Ran the matrix lobby scene and it never sounded so good. Zero distortion at absurd listening levels, none. (my ears were ringing)

Brought 1 pair to a friends house to audition them next to some bose, klipsch towers, and polk bookshelves. Easily beat the polks and bose. The klipsch not so much but thats just a bit unfair because they cost 10x as much and theyre towers.

Here' just a quick pic of one. sry no internal shots.

So are the 4 - DV-62si speakers in a different setup than the FH6-LCR??? What kind of setup are you running? What are your front speakers?

No they are apart of the same setup. The DV's are the rear channels (4) and i have the formula series (FH6) up front. with two towers (FH-6T)

Heres some pics so you can get a better idea:

These are the 4 rear channels:

Ok Im just curious why you didn't stay with the formula series all around? I would think having horn tweeters all around the room would be better than mixing and matching.

I am curious as well. I love BIC, and am considering their horn loaded speakers as well.

^^^ I have the BIC Acoustech Platinum speakers. I love them and for their price they are hard to beat. If you would like more info feel free to send me a PM.

I plan on ordering a FH6-LCR next week. Is this Mod still needed on the FH6-LCR?
post #9 of 13
He didn't quite understand the horns, so his mod wasn't a great idea. The original orientation of the horn was correct. If you were to stand the speaker vertically, yeah, you would want to rotate the horn. The sides with the greater surface area will produce a greater and more even dispersion. The way he set it up, he sacrificed horizontal axis response for a better vertical response, but horizontal response typically has a much greater effect on how good the speaker sounds. Only rotate the horns if you are going to stand the LCR up vertically.

Thanks "shadyJ".......... It's gonna be used as a center.

How are these guys doing?
I'm looking at getting some in the next couple days.

Hey all, I just picked one of these up yesterday and it had a rattle in it out of the box.

So, I took out the tweeter and found that the crossover was loose inside the cabinet. There is a large piece of double sided tape stuck to the cabinet and the crossover had come loose or it had not been pressed down hard enough on it. The stuff was still plenty sticky, just needed to press the crossover down onto it and it held fine.

While inside I noticed that the box and construction is decent, there is some fill lining the sides of the box, and even the individual wires are wrapped in foam to stop rattles. The speaker clips have the locking tabs on them so they stay secure on the drivers.

But, when I re-assembled the speaker I accidentally changed the orientation of the horn.

In essence I did this "mod" recommended here.

I checked it out, saw that it was wrong, and switched it back to the original orientation as suggested here in this thread.

I can report that the speaker sounds better as shipped.

NO MOD NEEDED if you are using it as a center.

I have a Yamaha rx773 and I ran YPAO with the horn flipped, will need to re-run now that I fixed it.

Regardless, even with the improper YPAO eq, I like this speaker so far, the higher efficiency means you can turn down the overall volume and still hear the dialogue.

Of course, I was replacing a Best Buy cheap KLH surround package center channel with 2 3.5 inch mids and a small tweeter so it was gonna be a big improvement.

While watching the Daily Show last night I noticed that the guest kept fidgeting and picking at his suit and tie.

When he did this, I could actually hear his hand scraping his mic and the little changes in the sound as he moved his hand around while he was speaking!

Also, the horn tweeter of the BIC seems like a better match for the bullet cone tweeters of my Cerwin Vega PD-9 main speakers.

They are really efficient speakers as well and the timbre definitely sounds more matched now.

So, so far so good with this thing.

I don't think you can go wrong for $100.

Speaker is built well, hefty, has decent parts inside and out, and it still fits nicely on top of my old school SONY KD36-XS955 CRT display.

Seems like a worthy upgrade if you are still running a cheap center from an HTIB or something.

But, if you are using it as a center, do NOT switch the horn orientation.

As noted above, it may seem counter intuitive, but it's supposed to be that way.

You are going to notice in about two weeks they will sound way better, at that point you may want to replace you left and right with them or the tower version of them. There's no way those old cv's will match sq wise what the fh6 can do.

When you use them as left and rights, then you do need to change the horn rotation. I have them running across my fronts for LCR.
