post #3121 of 5087
Dr Hsu,

I was wondering if I was right about having the cross over set at 60hz. Will that put less load on the sub so it won't run out of steam so easily?

Up until this week I've only had the 602s and am looking forward to building out the entire HT.
Thanks for any help available!

That is a huge space! Definitely need a 15H. Your suggested location is probably the best with WAF in mind.

I was curious if the numbers you posted are the raw numbers or the corrected numbers. For example, the Radio Shack SPL meter is down 7 dB at 20 Hz. A 75 dB meter reading would actually be 82 dB. Given that your averaging is from 31.5 Hz and up, it makes little difference since corrections in the range is minor.

No apologies necessary. I actually have an Extech model #407730 SPL meter. From the literature on the meter, the roll-off on the meter is very similar to that of the Radio Shack meter. The average I posted reflects the roll-off adjusted SPL readings (roughly +1.75dB over that range).

Just the opposite IMHO. You want to put more load on your subwoofers, and less on your receiver/amp/speakers. The subwoofer, IMHO, does a much better job of handling bass in the 80hz and below range (some people would argue 120hz and below if you cannot localize it).

Even in max extension mode?

I guess that depends on what main speakers you have, how efficient they are, and how powerful an amp you have driving them. If you have a 15H, the sub most likely will have more headroom than most main speakers... biggrin.gif

After a year+ of lurking, reading, debating, dreaming, convincing, I finally submitted my order for a vtf-15h biggrin.gif. This is going to literally blow away my current 10" Onkoy HTIB sub...

That, I believe it will. I actually ordered on the Sunday night before Thanksgiving and it ended up taking a full week foe Fedex ground to get the thing from the west coast to the east coast. I ended up not having the sub over the full 4 day weekend. That really bit the big one. With the prices of s/h on this sub I would expect it to be put on a plane. I would expect slow shipping if it were free like one of the competitors. Oh well, I have it now. Enough belly aching.

I hope you get yours a lot sooner. I'm still learning my way around mine. I'm sure you will love it.

No one ships anything for free, especially large and heavy items. Any business that says free shipping has the shipping built in the price.

You're right, of course.

Thanks for the feedback. After a bunch of reading, I went ahead and ordered. I actually have another sub on the way, but it's going to get RMA'd as soon as it gets here! smile.gif

You should definitely play around with crossover settings and see what you like best. My speakers will play down to 40hz or so cleanly, but I still crossover at 80hz because the sub does a better job and it puts less strain on the receiver. By crossing over at 80hz or so, I feel it gives the speakers more headroom as the receiver is not being strained to play lower frequencies.

Again, it is always best to compare between your speakers and subwoofer to see which you prefer, but I would 100% not be worried about putting strain on your subwoofer for bass between 60-100hz.

I have heard very good things about those ARX speakers, would like to hear a pair one day, they seem like a great value.

Congrats, it is a great subwoofer. I have been nothing but pleased with mine, and I have a big room like yours. I had owned several subs that really strained in the room and could not keep up. The VTF-15H has been a champ.

Where do you live? I live in Minnesota, and I ordered my VTF-15H on a Sunday and had it at my house on a Wednesday afternoon.

I'm just NW of you in Buffalo. I can't imagine the shipping schedule would be any different for me being a half hour away from where you're at.

With those, the 15H definitely have more dynamic range! Crossover at 80 Hz..

A great HT would certainly make the winters more enjoyable... biggrin.gif

Sorry Dr I don't have the 15H, I have the VTF3 MK4. LOL, remember I was contemplating selling the MK 4 and getting the 15H. So will the MK4 have plenty dynamic range?

I ordered mine a month ago. To go from anaheim to louisian only took a week so if you are closer than that then expect less time.
post #3145 of 5087
Just got my tracking info. Looks like it going to be a long weekend. Its ETA is Monday. Oh well, I've waited over a year. As hard as it will be, I guess I can manage a couple more days.
post #3146 of 5087
Its worth it. Ever since I bought mine Ive not once thought "man, I need to consider upgrading my sub". Whenever you finally feel that way about an AVR, display, whatever, it lets you know you got whats right for you.

Exactly why I got this sub. I have always wanted it, but lately was considering going to dual Legends. When they were on sale last week I almost went crazy trying to decide which route to go, but when it came down to it, I knew that if I went the Legend route, I would always have the 15h in the back of my head and wouldn't be satisfied. That was also one of my winning points for the WAF!

Well I just received 4 15" Dayton DVC 385-88 drivers. I am going to build 4 ported subwoofers that are tuned to 19hz and are about 5 cu ft (internal) volume. I purchased an iNuke3000DSP to power all four and will be using DSP/EQ and purchasing measuring equipment to get everything integrated.

The four subs plus the VTF-15H should be pretty crazy, and hopefully the VTF-15H integrates well, otherwise I may have to sell it and build a few more subs.

Here is what the four subs look like in the room after I modeled them (note, this does not include the VTF-15H which I intend to keep and suspect it will add another 3db+ across the spectrum). Should have a system that will play at reference level from the seating position and will play cleanly well into the mid teens with room gain:



Am curious on thoughts from the good Dr. or others as to how they think the VTF-15 will play with these DIY subs.

Quick question...


Do you guys think it's worth running a Klipsch sw-450 in same room as my 15H? The room is about 1,400 cubic feet.
post #3150 of 5087
No! It would only make it worse.
