Dual VTF3-MK2 or single VTF3-HO with Turbo?

I currently have one VTF3-MK2 in the front left hand corner of my 13'x25' room. I have read that the VTF3-HO with Turbo performs as well as four VTF3-MK2's without turbo. Even still, wouldn't dual lesser performing subs like the VTF3-MK2 provide a more constant response throughout my room than a single HO especially when placed at opposite ends of the room?

These are my options:

1) Purchase the turbo for my VTF3-MK2

2) Purchase a second VTF3-MK2 and eventually add turbos to them

3) Sell my VTF3-MK2 and purchase a VTF3-HO with turbo.

With my room being 2600 cubic feet, which option would you choose?

Perhaps in the very deepest bass, but in the upper bass 50hz+, the dual VTF-3 MK2 will outgun the HO.

Hi

If you can get a second VTF3-MK2, that would be my first choice of the options that you listed. There is another option that might be very satisfying, that would cost about the same as a second VTF3-MKII.

All the Best

Are you having a problem frequency dip at your primary seating position? If so, what frequency and how many dbs??

Also, what other speakers are you using?

Yes. Even though I'm using the 38% rule (placing my listening position 38% away from the rear wall in relation to the length of my room), I still have a dip in that area and towards the middle of the room of roughly 10dbs compared to the other ends of the room. Walking towards the corners increases again considerably. I'm using the Klipsch Reference series RF-7 mains, RC-7 center, and RS-7 surrounds. I am also considering getting some bass traps for the corners.

dbossa,

If you are up to experimenting, place your current sub immediately behind your primary listening position and rebalance your sub level relative to your other speakers. Also, correct the sub distance setting in your preamp/receiver. This should help a lot with getting your sub's frequency response level.

If you find that you sub sounds a bit directional, try lower crossovers till you reach the point that its non directional.

I would try this before springing for more subs. Wish I had done it before buying a second sub which I might be ebaying soon.

I used to have the sub behind the listening position when my couch was towards the middle of the room. I also equalize with a BFD and REW. However, now that I moved the couch back there isn't as much room behind it for a sub since I have a small table for games there. I'll try to see if I can make some room and try again. I just felt that maybe having a sub at opposite ends of the room would really pressurize the room more during deep bass movies.

I went from a dual VTF-3 MK2 to a -3 HO w/turbo and IMO the -3 HO w/turbo out performs the dual MK2 setup I had. It outperforms the MK2 setup in SPL, extension, and sounds at least as goos if not better on music and movies. The MK2 setup was incredible, but if you asked me to trade my single HO w/turbo for a dual MK2 setup I'd tell you to have a nice day I'm keeping the HO. It's that good.

I emailed HSU earlier today and asked them about my options above. They suggested that I get a turbo for my existing sub. Though, I'm wondering if it wouldn't be better to just upgrade the whole thing to the HO with turbo.

I just figured that having dual subs at opposite ends of the room would smooth out the room response considerably vs having only one sub.

My main concern is that I orginally bought my unit through a local distributor and now I have to order from the US. I'm really curious to know what the customs/duties fees would be for something like that. Wouldn't be too good to have a guy show up at my door with the sub asking for 40% extra to cover the border crossing

Dont know if your still debating on adding another 3.2 but here is a dealer in Canada that has some left.

Yes, this is the guy that I bought my current one from.

Today is your lucky day. Not only did I have dual VTF-3 MK2 subs, but when I started selling my MK2 subs to upgrade to the HO w/turbo I bought a turbo first and added that to the single MK2 I had left after selling the first one. The single MK2 w /turbo is just no match for the HO w/turbo The turbo did add 3-4dB and makes a nice improvement, but the HO w/turbo is in a different league.

Here's some links of what it was like when I had the dual MK2 setup the single MK2 w/turbo and a comparison between the HO and MK2 w/turbo. As good as the different MK2 setups were(and they were damn good) the HO w/turbo is still better.

I'm sure that the HO w/turbo will still completely blow away the 3 w/ turbo. My question is this:

What about DUAL VTF3-MK2 w/turbos vs a SINGLE HO w/turbo? The duals would be placed at opposite sides of the room for a smoother bass response throughout the room.

Any idea?

The reason is that I could pick up another 3 VERY cheap and eventually add the turbos to both of them.

Can't answer from experience since I only had a single 3 MK2 w/turbo, but there will always be a limitation to the 3 MK2 w/turbo, because your still running through the MK2 3" ports even though they are connected to the turbo's 4" tubes. The limitation on the MK2 was never the amp, the amp has had more than enough power it's always been the 3" ports and those are still there even with the turbo's.

My room is virtually the same size as yours (13x25). It seems that the dual VTF3-MK2s were almost overkill for your room. I could pickup a second one for about $630 whereas it would cost me almost double that to get an HO shipped here across the border. I'm beginning to think that dual 3's would be more than sufficient for my room. Do you disagree?

One other question: Would you say that the turbos on the 3 was definitely worth the investment? Or less so?

dbossa

Discussion Starter · #18 · May 18, 2007

I just pulled the trigger on a new VTF3-MK2 for roughly $635 USD or $700 CAD with all taxes and shipping included. I'll eventually add the turbos if I hear that it's really worth the investment.
