I have searched the forums and only found tangential information on the topic I am researching. I apologize if my search query did not catch this question. I currently have a 5.1 speaker setup. I am adding two rear surround channels for a 7.1 setup. My problem is, my sofa is placed against...

My subwoofer is humming. It is even humming when my system is off. About three days ago I came home from work and my BFD was displaying the letters AA something or other (I should have written it all down) in the display. I didn't think much about it. I turnrf the BFD off. I turned the BFD on...

How many of you routinely listen to your HT at reference level? If you listen @ below reference level, how many db below reference level do you listen? The reason I ask is that if I try to watch a movie @ reference level, everyone in the room but me thinks its too loud.

I've got a question about the table in your BFD EQ spreadsheet. TIA

It is a 5mm X 20mm 12A, 250 volt, GDA ceramic fuse. McMaster-Carr and Digikey do not appear to carry this fuse. Anybody know where I can find one?

I have used a BFD for the last year or so to tame some room modes. In particular, I have a 6bd hump at 35 hertz and a +12db hump at 47 hertz. These have been present in any sub I have used, so I know its a room mode. My problem is that I cannot get the +12 db hump at 47 hertz flat without using...

Wow! The Tumult can really play loud. It's clean too. I have it mounted in a 6.15 ft^3 box tuned to about 19.5 hertz. I am using a Keiga 52100, 1,000 watt plate amp from Kyle at Acoustic Visions. I only listened to a little music (Big Head Todd and the Monsters Perfect World) and a snippet of a...

I built my Tumult enclosure. When it came time to use t-nuts and machine screws I used some #8-24 t-nuts and screws that I had on-hand and I bought some addittional t-muts and machine screws at a local big box home improvement store. Initially, #8-24 machine screws were common locally. I had to...

My Tumult makes my amps shut down at relatively low levels. Heres the story. I hooked my Tumult up to my Keiga 52100 (1,000 watts @ 4 ohms). I calibrated it to my mains, center etc at 70 db. This corresponds to a level of about 70 on my receiver. I then put in the pod race scene on Episode I and...

Aaaaaaaarrrrrrrgh! I had a handtruck mishap and chipped a 1/4"X1 1/2" piece of veneer on the baffle of my Tumult. Should I use some of the cherry wood filler I picked up at Woodcraft, or actually try to patch this with another piece of cherry veneer? I figured I can cut a suitable patch from...

Last night I picked up two sheets of 4' X 8' cheery veneer at a cabinet supply warehouse. The sheet looks like it was made from edge-glued 6" boards, then sliced thin. Now I know that to get a 4' wide piece of veneer you have to glue some boards together, but this is really obvious. Did I get...

I am using Gorilla Glue on my Tumult enclosure. When I get a little glue squeeze-out on the inside of the enclosure, this stuff is really hard to get off. If I don't remove the squeeze-out, it would be difficult to impossible to seal the box with silicone. OTOH, the box seems pretty well sealed...

Any of you guys use a handheld power planer. I need to plane a bit and am considering purchasing a hend held power planer. In a related question, is it possible for MDF to shrink or expand with humidity? I cut a panel for my enclosure, then used a router with a straight-cut bit to make 8...

I have a nail gun that shoots 2.25" finishing nails. I am building a box with most panels 1.5" thick. I was planning to use the nails from the nail gun instead of clamps. If I try to use a 2.25" finishing nail through a 1.5" panel, will this give enough clamping force for Gorilla Glue to set and...

Does anyone know the Le on an Stryke HE 15.

I found some Wilsonart laminate that I must use on a project. It is Biltmore Cherry. Beautiful facsimile of wood. I ordered a sample. Still want to use it. However, the sample is very thick. This would appear to lead to an ugly edge showing on the edge of the laminate. Has anyone here used...

Al Did you just use the gasket that came attached to the Tumult frame to seal Craig's cabinet, or did you use additional gasket material? I ran out of gasket material and was curious if I needed to order more.

How many speakerbuilders here use Unibox? Do you think its accurate? I have been using Unibox, but I don't have that much experience. Looking for some others peoples opinions. Thanks

Is anyone aware of any FREE software that can optimize panel layout for cabinet parts on sheet goods (MDF).

Last Tuesday, I called Ampman Audio (the authorized dealer I ordered my Tumult from). They returned my call and stated that Tumults were shipping last week. Anybody get their Tumult yet?

Wow! These things are massive. Picked up the 6" Aeroport at my local Rockford Fosgate dealer tonight for $35.68. These things should really make the Tumult tumultuous (sorry). These things will need a massive hole in the enclosure to install. Therein lies the problem. I build an enclosure...

Purchased a Panasonic CP72S tonight at Circuit City. My mother and father-in-law gave me a generous gift card for Christmas that was applied to this purchase (thanks mom and dad. Panasonic also has a $30 rebate on this model until March. It is sad to say that I have been using a Sony...

Lets have details. What size? Ported, PR or sealed? Finally how much power are you going to put to it? I am leaning towards sealed with a linkwitz transform and 2000 watts. The sealed enclosure will be about 47 liters. I couldn't find a ported box that really worked well with this woofer...

I was hoping you guys could help me locate a decemt 15" woofer for a subwoofer project. The kicker is that I don't want to have to buy a 1,000 watt amp to power it. Can you get good performance from a Tempest or a PE DVC 15" with a 250 watt plate amp? I currently have a PE DVC 12" in a 3.1...

I want to know what you think of your SR600. I own the SR600. I have little experience with HT. I can tell you that it easily hits reference levels with my Audax HT kit speakers. These speakers are fairly inefficient (87ish db and one watt meter). The sound quality seems to be pretty good...

On the omaha Beach chapter on Saving Private Ryan, I am having some dialogue intelligability problems when played back at reference levels. I know they are screaming and all of the effects are around them, but is it the mix or my center channel? I am running this on DTS. BTW, DTS does appear...

Can there be room modes that are too tough to tame? I have a room that is 23X13 with an open double doorway to a 14X22. My sub is placed in a corner furthest from the double doorway. I have a broad peak from 45-64 hertz of 10 db. I can tame most of the peak, but a peak at 46db remains no...

I picked up an Onkyo TX SR600 tonight at the Crutchfield outlet in Charlottesville, VA. I have not completed the install yet, but I have been contemplating the following. I have noticed that people have been able to localize the rear channel in 6.1 surround. It has been suggested that...
