I would also go with option 1. While my S-Center matches well with the S-38's, it does not have the bass capability of the S-38s (If I could have bought a single S38, I would have)and I can sometimes hear it strain while the S-38's are just cruising ( I like my movies loud). BTW, this is with...

The S38's make no provision for mounting, you need a sturdy shelf to hold them. I have S38's in front and S36's for surrounds and there is a huge difference in bass capability between the two. I knew that going in, but did not have a place for S-38's that would work since my surrounds needed to...

We have LCD business projectors at work that are more than 6 years old (they are beasts in size compared to the newest ones) and they are still working. The issues I have seen with them are dust (just a maintenance issue, could be fixed) and two of the oldest 3M units now have a slight purplish...

Unless you have a lot of flexibility in placement and a lot of time and patience, having multiple bass sources will more likely give you worse response than a single source in an optimized location. I have had that experience and will be moving both drivers to the same location as soon as I get...

Another factor in deciding screen size is how much control of ambient light the is in the room. I looked at a Sony HS20 on a 110" Firehawk screen today at a dealer that had a pretty reasonably set up room; dark walls, controlled lighting with dimmers etc. The demo started out with a few...

The Bozaks were great speakers in their day. They used "infinite baffle" woofer designs (very small Vas) in their systems. The ones I remember hearing were the Concert Grands; (4) 12 woofers, several midranges and a line array of tweeters firing through a slot. Their main competition at the time...

If you have the room and ambient light control, you can buy a Sony HS20 LCD Front Projector, a 92" to 106" Stewart Firehawk Screen and a Sony HDTV Satellite/terrestrial/NTSC receiver for $5000-$5500. The HDTV Quality was outstanding at 13 feet from a 106" screen with no "screendoor effect". I...

I also agree with a stacking or side by side arrangement; I have 2 identical subs and I would be much better off having them both in the same location if that were possible based on measurements I took. I can not do that with my current "box speaker" setup, but plan to switch to an IB setup to...

I also have a rotozip tool (the Advantage saw) and recently used the circle cutting fixture for it to cut a hole for a Tempest; ended up with a perfect circle.

The other issue with having 2 subs is that unless you have a lot of flexibilty in placement and the patience to measure and check things out to optimise the in room response, your results may be worse than having one. This was the case for me; on sub was pretty flat down to 20Hz, the other...

Has anyone done (or seen) a comparison of picture quality between the 2 systems? Since both now cost nothing for equipment (current offers on 3 room systems) and the programming is a wash for me, the key factor is the picture quality that I will get on my RPTV. I currently do not have an...

For a sanity check, I called a couple of pro gear suppliers this afternoon that advertise that they carry both lines (as well as many others). Both reps that I talked to said to buy the QSC because it was a much better amp, despite the lower power rating. One of the guys was a repair tech...

Thanks for the info Wayne. It sounds like it is a well built amp. They even give it an FTC rating of 400W in to 4 ohms (unusual in pro amps); 450W EIA at 1KHz; you have to go up to the next amp in the RMX line for that power. I asked about Behringer (in general) at our local Guitar store...

Has anyone used a Behringer EP 1500 for driving passive subs? I was looking hard at the QSC RMX 850 because it seemed like a quality amp at the ~ 300.00 price point, but it seem like you get more amp for the $$$ with the Behringer all other things being equal. One of my old audio power...

If the amp has a manual on position, another work around is to put together an outlet box with a small high amperage rated relay in line with it (normally open) and run the coil to a switched outlet on your pre/pro outlet so the amp turns on with the preamp. Since I have passive subs with a...

When you finish your crossover, you should find that there are only 2 wires to connect to your receiver. I have not looked at the schematic, but it may be confusing showing a low pass section and separate high pass section of the crossover ( which you could bi-wire to the receiver). These can be...

If you plan on using it as a passive sub ( not using the plate amp that is built in), there is no technical reason you cannot try to use the box if you can find an inexpensive driver that models well in the volume you have to work with. I recycled my old 4 way towers with Tempests and they...

Jayson, I have 2 Tempest based subs and my results are pointing in the direction of moving them to one location. I think that 2 subs will give you smoother overall response in the room IF you have a lot of flexibility in placement (KEY) and you take the time to do measurements and go through...

Interesting thread. For those who do not like "horn sound", don't go to a movie theatre or a live concert (orchestral music excepted) because you will definitely be listening to horns. That said, there is a wide variety in the quality of sound in those venues, from shreiking "in your face" to...

If you are talking passive subs with a separate amp, you would have to give them the same power. You may be able to do that with an existing amp depending on the sub's impedance and what your amp is capable of. For example, if you have an 8 ohm sub and your amp is 200 W into 8 ohms and 350 in...

Jeff, One of the reviews linked from Adire's site commented on measured distortion rising below the crossover, likely due to cone break up. The distortion came down again above the crossover when the horn took over; physics at work. Having both to compare side by side, you can give your...

Graham, That is what I really want to do. The dual Tempest IB models at 10 Db greater output at 20 Hz than the single sealed mid-Q setup I have in near field measurements ( 1 meter). In the room, based on measurements I have taken already, If I could put the manifold outlet where the...

Wayne, I am using regular audio power amps. I have a couple of old (25+ years!!) SAE power amps that are darn near bulletproof to drive them for now. If I go the IB route, the Tempests will be excursion limited so there is no need for more power than what I have. I have been looking at...

If your reciever has the preamp outs for all channels, there is no reason that you can not. I used a separate power amp on my last HK receiver; that one was from the generation that had lower power to the surrounds than the fronts. Since I had a couple of spare power amps around, I just used on...

The other option if you can't find an old speaker is to take yours to and audio dealer that carries a variety of centers. Hook it up to one channel and run the level calibration tones on the receiver (pink noise) and compare the characteristics of the sound. Since it is "broadband" noise, it...

I forgot to upload the chart. I forgot that I can see it even if is not on the server, it has been a while since I updated the page.

Thanks Wayne, let me see if I can fix it

I finished converting my second AR tower to a Mid Q Tempest Sub over the holidays and finally got around to taking some in room measurements (AT THE LISTENING POSITION) with a Radio Shack Meter (with readings corrected) of each sub individually and the total response from both. Overall, I am...

Interesting. I have S38's and an S Center in front and S36's in back, I liked the idea of even higher efficiency speakers; how do the HE series compare in dynamics? One of the things I really like about the JBL's is the ability to stay clean at high volumes, and how little compression they have...
