Introducing the Sierra-LX!!!

[hometheater]

What is the thought about bridging an amp to drive the LXs? You gain a lot of power but the min impedence the amp can drive increases to 8 ohms.

Which amp? What's the power of it now (unbridged) - any reason to bridge (aside from the increased power)?

I would need to buy the amp but it's an old Parasound HCA-750A. Would go from 75 wpc stereo to 250 watts mono.

I'm currently using it as a center with the Denon x4400h which is rated at 125 wpc but not all channels driven. It's driving that and 4 surrounds and 4 atmos speakers. The LR are already driven by a separate amp.

[racrawford65]

If you go that route, I'd probably try it with just one channel to drive the center before bridging (I'm assuming this is user selectable). Unless you are sitting really far back, 75 watts should be ok. According to the Parasound page, the amp would sound better in stereo.

Ok, thanks. I'll just stick with my Denon for now and maybe pickup a Hpex NC500 amp in the future.

If you go class D, check out VTV amplifier. Also, look at the Pascal and Purifi options. I use a custom 7 channel Pascal for my center, surrounds, and 4 Atmos. When I had my 720, I was using a 4channel VTV Pascal for Atmos

Thanks. I’ll have to look into passive single order high pass filter options. My integrated amplifier doesn’t have any fancy features.

Did you purchase the LX directly from us? Another option is to use the Q-Plugs included with the LX to seal the port. You would then need to set the LP filter on your subwoofer higher to 80Hz. However, sealing the port will cause the woofer to have greater excursion and if you are playing at very loud volume levels, this could potentially cause problems. Best option, high pass your speakers.

Yes direct, order was placed 3/23/2022. If there where foam plugs in the box, I’ll have to search the attic for the boxes. My integrated amp is plain jane, so I’ll have to look at making a passive high pass filter.

Yes, we do include a complete set of our Q-Plugs with each LX pair we ship. Please check your shipping boxes and let me know.

Thanks!

I’m guessing the answer is no, but figure it can’t hurt to ask. For an additional charge is there an option to get the cabinets in a glossy finish? Also contemplating the towers. My favorite look are the high gloss walnut option Revel has. I’m guessing a glossy Espresso would be close, just a bit darker.
