This is just the service to upgrade your HPM 100 crossovers and not the actual crossover offered here. As you can see from the pictures the crossover is in two separate boards, as all the original coils and capacitors have been replaced with higher quality. The binding posts have been replaced also. Breathe new life into your HPM 100s with this upgrade. This service is for a pair of crossovers to be updated. Just ship yours to me and I'll upgrade them and ship back to you. For one pair of crossovers purchase one and for two pairs purchase 2. You can purchase 1 pair of HPM 60s and 1 pair of HPM 100s as quantity 2, so in all 2 pairs.

***The crossover with the control pots is the HPM-150***

90 Days warranty on parts and labor. All sales are final and no returns. Each item is tested before shipping.

CUSTOMERS COMMENTS:



"I just wanted to thank you for the great service you offer. The turnaround time is great and the price is reasonable.
The crossovers really woke up my HPM 100s, and probably saved me from selling them. No more confusion about which speaker handles which frequencies. The soundstage is now wide and three dimensional. The clarity is amazing. The speakers now realize their full potential. I'm quite happy with them, and I will spread the word!"

"I’ve been listening to a variety of music for about 3 hours today. I’ve learned that the HPMs like high power solid state equipment rather than my tube amp. They sound much better than stock. More open, airy mids and highs.
The bass seems cleaner, not as dark as before. Much improved imaging and soundstage. Overall I’m very satisfied with the upgrade."

"Clear definition and great separation on the tweets and mid that was hard to distinguish prior. Crisp and full of life. My go to test is a Tel-arc CD, Trumpet Spectacular with Doc Severinsen playing with the Cincinnati Pops. That trumpet sounds amazing in those smaller speakers and the orchestra just as amazing slamming out that woofer bass. It is as close to being there as one can get! I am very happy with this upgrade!"

"Worth the wait! Made my HPM-100s sing! Wall of sound with imaging to die for! Everything is sorted and sounds very detailed. Thanks very much!"

I have to say I am really impressed. The biggest difference is the vocals, clearly separated from the music. I upgraded them and then sat on my couch until 1am trying all different types of music, really a night and day difference. I have tied out the new L100s and I think these make my HPM-100s sound much better, thank you.

Been listening to the upgraded crossovers since installing them a few days ago. It was tough to live without my speakers while the crossovers were getting serviced, but it was well worth the wait. The new crossovers seems to have brought my HPM-150's some more clarity and really expanded the soundstage. Really professional work. Solder connections are strong! Will do business with again.

I've been listening to my HPM-60's for about a week since I received the upgraded crossovers and I would like to say, they sound great. The midrange is better than before and the highs are crisp and clean. I encourage you to send your crossover in for the upgrade, you'll be glad you did.
