In Wall Subwoofer Details
A subwoofer is designed to reproduce the lowest of audible frequencies and will give you that spine-tingling rumble effect that takes you out of reality and into the plot. With dual 8" polypropylene woofers and 240 Watts of power handling, the IWS-88 in-wall subwoofer performs excellently for home theater surround sound applications as well as for listening to music. Like all OSD Audio speakers, the IWS-88 includes a dog-ear bracket system that mounts securely to the sheet-rock after the cut-out hole has been made and the speaker has been dropped into the hole. The grille is paintable to match your room decor and we even include a cutout template that doubles as a paint shield. You'll experience thunderous, room-filling bass without filling up floor space.
Amplifier Suggestions Because this is a passive speaker, it will require a subwoofer amplifier to power it. Luckily, this kit comes with the subwoofer amplifier.
*Note: Requires Additional Subwoofer Amplifier, which is Included!
Subwoofer Amplifier Details
OSD Audio’s SMP250 Mono Subwoofer Amp gives passive subwoofers up to 250 watts of power so you can experience all the crashes, crunches and car chases with spine-tingling exhilaration. Designed for use with higher wattage passive subwoofers such as in-wall subs that require external power, the SMP250 Mono Subwoofer provides stable power and enhances the low frequency sound effects. Packed with high-end features, this sub amp includes a variable high cut filter that routes higher frequencies to main speakers so subs can concentrate on the low frequency sound effects they are designed to handle. The result is bass that does not sound muddy or overly thumpy but rather crisp and detailed. You’ll immediately feel and hear the difference. Other features include a back panel adjustable gain and volume control limiter to protect the woofers as well as low-level and high-level pass-through input/outputs to cover newer and old school sound systems.
Why Do You Need Subwoofer Amp? In-wall subs are most commonly passive. After all, it’s not so easy to install a 100-pound sub inside a wall. That’s where an amp like the SMP250 Mono Subwoofer Amp comes into play. This amp not only adds necessary power but the high-cut filter keeps low bass away from your surround speakers, which in turn gives you much cleaner highs and midrange. This subwoofer amp does much more than supply power. It also improves the overall sound quality of your entire surround sound system.
What Is A Class A/B Amplifier?In home theater, Class A/B are the most common because they combine the efficiency of Class B with the sound quality of Class A amps. A Class A amplifier uses the input signal 100% of the time, which means that the output signal to your sub matches the input signal from your receiver. The result is virtually no clipping or distortion. Sounds perfect, right? The downside is that Class A amplifiers run very hot because the transistors are working all the time. Class B amplifiers only amplify half of the input signal which creates some distortion but these amps are far more efficient than Class A amplifiers and run a lot cooler. A Class A/B amp combines the best of A and B, so distortion is lower yet efficiency is high so sound quality is truly maximized.
